+# Vendored skills
+
+These five skills are copied from an external repository, not written here:
+
+- `grill-me`, `grilling`
+- `improve-codebase-architecture`, `codebase-design`, `domain-modeling`
+
+Source: https://github.com/mattpocock/skills
+Pinned at commit `84fdeffd12f2ee307994d1eb6feb48173b6e0502`.
+
+They form one dependency closure — `grill-me` is a stub that runs `grilling`, and
+`improve-codebase-architecture` draws its vocabulary from `codebase-design` and its
+CONTEXT.md upkeep from `domain-modeling`. Removing any one breaks the others.
+
+Local changes on top of upstream, kept to the minimum so a refresh stays a diff:
+
+- Flattened the upstream `skills/engineering/` and `skills/productivity/` split, since this
+  repo's skills are flat.
+- Replaced each SKILL.md's markdown links to its own bundled files with plain repo-root paths
+  in prose (`.agents/skills/<skill>/FILE.md`). Upstream's sibling-relative links break when the
+  file is read through the `.claude/skills/<skill>/SKILL.md` symlink, which mirrors only
+  SKILL.md — and a repo-root *link* is equally wrong, since a markdown target resolves relative
+  to the file containing it. Companion files keep their sibling-relative links; they are only
+  ever read at their real path, never through the symlink.
+- Dropped the upstream `agents/openai.yaml` files — Codex packaging metadata for that repo's
+  own plugin distribution, unused here.
+- **Removed every ADR path.** Upstream, `domain-modeling` offers to write Architecture Decision
+  Records into `docs/adr/` and `improve-codebase-architecture` reads and cites them. This repo has
+  not adopted ADRs, and a skill that offers to create them is how the practice arrives by side
+  effect rather than by decision. Deleted `domain-modeling/ADR-FORMAT.md`, its "Offer ADRs
+  sparingly" section, and the `docs/adr/` entries in its file-structure diagrams; dropped the ADR
+  clauses from `improve-codebase-architecture` (intro, explore step, "ADR conflicts", the
+  offer-an-ADR bullet in the grilling loop) and the ADR callout row in `HTML-REPORT.md`. Also cut
+  "record an architectural decision" from `domain-modeling`'s description, since that phrase is an
+  invocation trigger. What remains is CONTEXT.md and ubiquitous-language work only.
+
+To refresh, diff against the same paths at a newer commit and re-apply these four changes. The
+ADR removal is the one that needs judgement: if the team later adopts ADRs, take upstream's
+version of those sections back rather than rewriting them here.

+# Deepening
+
+How to deepen a cluster of shallow modules safely, given its dependencies. Assumes the vocabulary in [SKILL.md](SKILL.md) — **module**, **interface**, **seam**, **adapter**.
+
+## Dependency categories
+
+When assessing a candidate for deepening, classify its dependencies. The category determines how the deepened module is tested across its seam.
+
+### 1. In-process
+
+Pure computation, in-memory state, no I/O. Always deepenable — merge the modules and test through the new interface directly. No adapter needed.
+
+### 2. Local-substitutable
+
+Dependencies that have local test stand-ins (PGLite for Postgres, in-memory filesystem). Deepenable if the stand-in exists. The deepened module is tested with the stand-in running in the test suite. The seam is internal; no port at the module's external interface.
+
+### 3. Remote but owned (Ports & Adapters)
+
+Your own services across a network boundary (microservices, internal APIs). Define a **port** (interface) at the seam. The deep module owns the logic; the transport is injected as an **adapter**. Tests use an in-memory adapter. Production uses an HTTP/gRPC/queue adapter.
+
+Recommendation shape: *"Define a port at the seam, implement an HTTP adapter for production and an in-memory adapter for testing, so the logic sits in one deep module even though it's deployed across a network."*
+
+### 4. True external (Mock)
+
+Third-party services (Stripe, Twilio, etc.) you don't control. The deepened module takes the external dependency as an injected port; tests provide a mock adapter.
+
+## Seam discipline
+
+- **One adapter means a hypothetical seam. Two adapters means a real one.** Don't introduce a port unless at least two adapters are justified (typically production + test). A single-adapter seam is just indirection.
+- **Internal seams vs external seams.** A deep module can have internal seams (private to its implementation, used by its own tests) as well as the external seam at its interface. Don't expose internal seams through the interface just because tests use them.
+
+## Testing strategy: replace, don't layer
+
+- Old unit tests on shallow modules become waste once tests at the deepened module's interface exist — delete them.
+- Write new tests at the deepened module's interface. The **interface is the test surface**.
+- Tests assert on observable outcomes through the interface, not internal state.
+- Tests should survive internal refactors — they describe behaviour, not implementation. If a test has to change when the implementation changes, it's testing past the interface.

+# Design It Twice
+
+When the user wants to explore alternative interfaces for a chosen deepening candidate, use this parallel sub-agent pattern. Based on "Design It Twice" (Ousterhout) — your first idea is unlikely to be the best.
+
+Uses the vocabulary in [SKILL.md](SKILL.md) — **module**, **interface**, **seam**, **adapter**, **leverage**.
+
+## Process
+
+### 1. Frame the problem space
+
+Before spawning sub-agents, write a user-facing explanation of the problem space for the chosen candidate:
+
+- The constraints any new interface would need to satisfy
+- The dependencies it would rely on, and which category they fall into (see [DEEPENING.md](DEEPENING.md))
+- A rough illustrative code sketch to ground the constraints — not a proposal, just a way to make the constraints concrete
+
+Show this to the user, then immediately proceed to Step 2. The user reads and thinks while the sub-agents work in parallel.
+
+### 2. Spawn sub-agents
+
+Spawn 3+ sub-agents in parallel. Each must produce a **radically different** interface for the deepened module.
+
+Prompt each sub-agent with a separate technical brief (file paths, coupling details, dependency category from [DEEPENING.md](DEEPENING.md), what sits behind the seam). The brief is independent of the user-facing problem-space explanation in Step 1. Give each agent a different design constraint:
+
+- Agent 1: "Minimize the interface — aim for 1–3 entry points max. Maximise leverage per entry point."
+- Agent 2: "Maximise flexibility — support many use cases and extension."
+- Agent 3: "Optimise for the most common caller — make the default case trivial."
+- Agent 4 (if applicable): "Design around ports & adapters for cross-seam dependencies."
+
+Include both [SKILL.md](SKILL.md) vocabulary and CONTEXT.md vocabulary in the brief so each sub-agent names things consistently with the architecture language and the project's domain language.
+
+Each sub-agent outputs:
+
+1. Interface (types, methods, params — plus invariants, ordering, error modes)
+2. Usage example showing how callers use it
+3. What the implementation hides behind the seam
+4. Dependency strategy and adapters (see [DEEPENING.md](DEEPENING.md))
+5. Trade-offs — where leverage is high, where it's thin
+
+### 3. Present and compare
+
+Present designs sequentially so the user can absorb each one, then compare them in prose. Contrast by **depth** (leverage at the interface), **locality** (where change concentrates), and **seam placement**.
+
+After comparing, give your own recommendation: which design you think is strongest and why. If elements from different designs would combine well, propose a hybrid. Be opinionated — the user wants a strong read, not a menu.

+description: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
+---
+
+# Codebase Design
+
+Design **deep modules**: a lot of behaviour behind a small interface, placed at a clean seam, testable through that interface. Use this language and these principles wherever code is being designed or restructured. The aim is leverage for callers, locality for maintainers, and testability for everyone.
+
+## Glossary
+
+Use these terms exactly — don't substitute "component," "service," "API," or "boundary." Consistent language is the whole point.
+
+**Module** — anything with an interface and an implementation. Deliberately scale-agnostic: a function, class, package, or tier-spanning slice. _Avoid_: unit, component, service.
+
+**Interface** — everything a caller must know to use the module correctly: the type signature, but also invariants, ordering constraints, error modes, required configuration, and performance characteristics. _Avoid_: API, signature (too narrow — they refer only to the type-level surface).
+
+**Implementation** — what's inside a module, its body of code. Distinct from **Adapter**: a thing can be a small adapter with a large implementation (a Postgres repo) or a large adapter with a small implementation (an in-memory fake). Reach for "adapter" when the seam is the topic; "implementation" otherwise.
+
+**Depth** — leverage at the interface: the amount of behaviour a caller (or test) can exercise per unit of interface they have to learn. A module is **deep** when a large amount of behaviour sits behind a small interface, **shallow** when the interface is nearly as complex as the implementation.
+
+**Seam** _(Michael Feathers)_ — a place where you can alter behaviour without editing in that place; the *location* at which a module's interface lives. Where to put the seam is its own design decision, distinct from what goes behind it. _Avoid_: boundary (overloaded with DDD's bounded context).
+
+**Adapter** — a concrete thing that satisfies an interface at a seam. Describes *role* (what slot it fills), not substance (what's inside).
+
+**Leverage** — what callers get from depth: more capability per unit of interface they learn. One implementation pays back across N call sites and M tests.
+
+**Locality** — what maintainers get from depth: change, bugs, knowledge, and verification concentrate in one place rather than spreading across callers. Fix once, fixed everywhere.
+
+## Deep vs shallow
+
+**Deep module** = small interface + lots of implementation:
+
+```
+┌─────────────────────┐
+│   Small Interface   │  ← Few methods, simple params
+├─────────────────────┤
+│                     │
+│  Deep Implementation│  ← Complex logic hidden
+│                     │
+└─────────────────────┘
+```
+
+**Shallow module** = large interface + little implementation (avoid):
+
+```
+┌─────────────────────────────────┐
+│       Large Interface           │  ← Many methods, complex params
+├─────────────────────────────────┤
+│  Thin Implementation            │  ← Just passes through
+└─────────────────────────────────┘
+```
+
+When designing an interface, ask:
+
+- Can I reduce the number of methods?
+- Can I simplify the parameters?
+- Can I hide more complexity inside?
+
+## Principles
+
+- **Depth is a property of the interface, not the implementation.** A deep module can be internally composed of small, mockable, swappable parts — they just aren't part of the interface. A module can have **internal seams** (private to its implementation, used by its own tests) as well as the **external seam** at its interface.
+- **The deletion test.** Imagine deleting the module. If complexity vanishes, it was a pass-through. If complexity reappears across N callers, it was earning its keep.
+- **The interface is the test surface.** Callers and tests cross the same seam. If you want to test *past* the interface, the module is probably the wrong shape.
+- **One adapter means a hypothetical seam. Two adapters means a real one.** Don't introduce a seam unless something actually varies across it.
+
+## Designing for testability
+
+Good interfaces make testing natural:
+
+1. **Accept dependencies, don't create them.**
+
+   ```typescript
+   // Testable
+   function processOrder(order, paymentGateway) {}
+
+   // Hard to test
+   function processOrder(order) {
+     const gateway = new StripeGateway();
+   }
+   ```
+
+2. **Return results, don't produce side effects.**
+
+   ```typescript
+   // Testable
+   function calculateDiscount(cart): Discount {}
+
+   // Hard to test
+   function applyDiscount(cart): void {
+     cart.total -= discount;
+   }
+   ```
+
+3. **Small surface area.** Fewer methods = fewer tests needed. Fewer params = simpler test setup.
+
+## Relationships
+
+- A **Module** has exactly one **Interface** (the surface it presents to callers and tests).
+- **Depth** is a property of a **Module**, measured against its **Interface**.
+- A **Seam** is where a **Module**'s **Interface** lives.
+- An **Adapter** sits at a **Seam** and satisfies the **Interface**.
+- **Depth** produces **Leverage** for callers and **Locality** for maintainers.
+
+## Rejected framings
+
+- **Depth as ratio of implementation-lines to interface-lines** (Ousterhout): rewards padding the implementation. We use depth-as-leverage instead.
+- **"Interface" as the TypeScript `interface` keyword or a class's public methods**: too narrow — interface here includes every fact a caller must know.
+- **"Boundary"**: overloaded with DDD's bounded context. Say **seam** or **interface**.
+
+## Going deeper
+
+- **Deepening a cluster given its dependencies** — see `.agents/skills/codebase-design/DEEPENING.md` (path from the repo root): dependency categories, seam discipline, and replace-don't-layer testing.
+- **Exploring alternative interfaces** — see `.agents/skills/codebase-design/DESIGN-IT-TWICE.md` (path from the repo root): spin up parallel sub-agents to design the interface several radically different ways, then compare on depth, locality, and seam placement.

+# CONTEXT.md Format

+## Structure

+
+## Language
+
+**Order**:
+{A one or two sentence description of the term}

+**Invoice**:
+A request for payment sent to a customer after delivery.
+_Avoid_: Bill, payment request
+
+**Customer**:
+A person or organization that places orders.
+_Avoid_: Client, buyer, account
+```
+
+## Rules
+
+- **Be opinionated.** When multiple words exist for the same concept, pick the best one and list the others under `_Avoid_`.
+- **Keep definitions tight.** One or two sentences max. Define what it IS, not what it does.
+- **Only include terms specific to this project's context.** General programming concepts (timeouts, error types, utility patterns) don't belong even if the project uses them extensively. Before adding a term, ask: is this a concept unique to this context, or a general programming concept? Only the former belongs.
+- **Group terms under subheadings** when natural clusters emerge. If all terms belong to a single cohesive area, a flat list is fine.
+
+## Single vs multi-context repos
+
+**Single context (most repos):** One `CONTEXT.md` at the repo root.
+
+**Multiple contexts:** A `CONTEXT-MAP.md` at the repo root lists the contexts, where they live, and how they relate to each other:
+
+```md
+# Context Map
+
+## Contexts
+
+- [Ordering](./src/ordering/CONTEXT.md) — receives and tracks customer orders
+- [Billing](./src/billing/CONTEXT.md) — generates invoices and processes payments
+- [Fulfillment](./src/fulfillment/CONTEXT.md) — manages warehouse picking and shipping
+
+## Relationships
+
+- **Ordering → Fulfillment**: Ordering emits `OrderPlaced` events; Fulfillment consumes them to start picking
+- **Fulfillment → Billing**: Fulfillment emits `ShipmentDispatched` events; Billing consumes them to generate invoices
+- **Ordering ↔ Billing**: Shared types for `CustomerId` and `Money`
+```
+
+The skill infers which structure applies:
+
+- If `CONTEXT-MAP.md` exists, read it to find contexts
+- If only a root `CONTEXT.md` exists, single context
+- If neither exists, create a root `CONTEXT.md` lazily when the first term is resolved
+
+When multiple contexts exist, infer which one the current topic relates to. If unclear, ask.

+
+# Domain Modeling
+
+Actively build and sharpen the project's domain model as you design. This is the *active* discipline — challenging terms, inventing edge-case scenarios, and writing the glossary and decisions down the moment they crystallise. (Merely *reading* `CONTEXT.md` for vocabulary is not this skill — that's a one-line habit any skill can do. This skill is for when you're changing the model, not just consuming it.)
+
+## File structure
+
+Most repos have a single context:
+
+```
+/
+├── CONTEXT.md
+└── src/
+```
+
+If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives:
+
+```
+/
+├── CONTEXT-MAP.md
+└── src/
+    ├── ordering/
+    │   └── CONTEXT.md
+    └── billing/
+        └── CONTEXT.md
+```
+
+Create files lazily — only when you have something to write. If no `CONTEXT.md` exists, create one when the first term is resolved.
+
+## During the session
+
+### Challenge against the glossary
+
+When the user uses a term that conflicts with the existing language in `CONTEXT.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?"
+
+### Sharpen fuzzy language
+
+When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things."
+
+### Discuss concrete scenarios
+
+When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts.
+
+### Cross-reference with code
+
+When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?"
+
+### Update CONTEXT.md inline
+
+When a term is resolved, update `CONTEXT.md` right there. Don't batch these up — capture them as they happen. Use the format in `.agents/skills/domain-modeling/CONTEXT-FORMAT.md` (path from the repo root).
+
+`CONTEXT.md` should be totally devoid of implementation details. Do not treat `CONTEXT.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else.

+
+## Header
+
+Repo name, date, and a compact legend: solid box = module, dashed line = seam, red arrow = leakage, thick dark box = deep module. No introduction paragraph — straight into the candidates.
+
+## Candidate card
+
+The diagrams carry the weight. Prose is sparse, plain, and uses the glossary terms (from the `/codebase-design` skill) without ceremony.
+
+Each candidate is one `<article>`:
+
+- **Title** — short, names the deepening (e.g. "Collapse the Order intake pipeline").
+- **Badge row** — recommendation strength (`Strong` = emerald, `Worth exploring` = amber, `Speculative` = slate), plus a tag for the dependency category (`in-process`, `local-substitutable`, `ports & adapters`, `mock`).
+- **Files** — monospaced list, `font-mono text-sm`.
+- **Before / After diagram** — the centrepiece. Two columns, side by side. See patterns below.
+- **Problem** — one sentence. What hurts.
+- **Solution** — one sentence. What changes.
+- **Wins** — bullets, ≤6 words each. e.g. "Tests hit one interface", "Pricing logic stops leaking", "Delete 4 shallow wrappers".
+
+No paragraphs of explanation. If the diagram needs a paragraph to be understood, redraw the diagram.
+
+## Diagram patterns
+
+Pick the pattern that fits the candidate. Mix them. Don't make every diagram look the same — variety is part of the point.
+
+### Mermaid graph (the workhorse for dependencies / call flow)
+
+Use a Mermaid `flowchart` or `graph` when the point is "X calls Y calls Z, and look at the mess." Wrap it in a Tailwind-styled card so it doesn't feel parachuted in. Style with classDef to colour leakage edges red and the deep module dark. Sequence diagrams work well for "before: 6 round-trips; after: 1."
+
+```html
+<div class="rounded-lg border border-slate-200 bg-white p-4">
+  <pre class="mermaid">
+    flowchart LR
+      A[OrderHandler] --> B[OrderValidator]
+      B --> C[OrderRepo]
+      C -.leak.-> D[PricingClient]
+      classDef leak stroke:#dc2626,stroke-width:2px;
+      class C,D leak
+  </pre>
+</div>
+```
+
+### Hand-built boxes-and-arrows (when Mermaid's layout fights you)
+
+Modules as `<div>`s with borders and labels. Arrows as inline SVG `<line>` or `<path>` elements positioned absolutely over a relative container. Reach for this when you want the "after" diagram to feel like one thick-bordered deep module with greyed-out internals — Mermaid won't render that with the right weight.
+
+### Cross-section (good for layered shallowness)
+
+Stack horizontal bands (`h-12 border-l-4`) to show layers a call passes through. Before: 6 thin layers each doing nothing. After: 1 thick band labelled with the consolidated responsibility.
+
+### Mass diagram (good for "interface as wide as implementation")
+
+Two rectangles per module — one for interface surface area, one for implementation. Before: interface rectangle is nearly as tall as the implementation rectangle (shallow). After: interface rectangle is short, implementation rectangle is tall (deep).
+
+### Call-graph collapse
+
+Before: a tree of function calls rendered as nested boxes. After: the same tree collapsed into one box, with the now-internal calls shown faded inside it.
+
+## Style guidance
+
+- Lean editorial, not corporate-dashboard. Generous whitespace. Serif optional for headings (`font-serif` works well with stone/slate).
+- Colour sparingly: one accent (emerald or indigo) plus red for leakage and amber for warnings.
+- Keep diagrams ~320px tall so before/after sits comfortably side by side without scrolling.
+- Use `text-xs uppercase tracking-wider` for module labels inside diagrams — they should read as schematic, not as UI.
+- The only scripts are the Tailwind CDN and the Mermaid ESM import. The report is otherwise static — no app code, no interactivity beyond Mermaid's own rendering.
+
+## Top recommendation section
+
+One larger card. Candidate name, one sentence on why, anchor link to its card. That's it.
+
+## Tone
+
+Plain English, concise — but the architectural nouns and verbs come straight from the `/codebase-design` skill. Concision is not an excuse to drift.
+

+
+**Never substitute:** component, service, unit (for module) · API, signature (for interface) · boundary (for seam) · layer, wrapper (for module, when you mean module).
+
+**Phrasings that fit the style:**
+

+- "Pricing leaks across the seam."
+- "Deepen: one interface, one place to test."

+No hedging, no throat-clearing, no "it's worth noting that…". If a sentence could be a bullet, make it a bullet. If a bullet could be cut, cut it. If a term isn't in the `/codebase-design` glossary, reach for one that is before inventing a new one.

+
+# Improve Codebase Architecture
+
+Surface architectural friction and propose **deepening opportunities** — refactors that turn shallow modules into deep ones. The aim is testability and AI-navigability.
+
+This command is _informed_ by the project's domain model and built on a shared design vocabulary:
+
+- Run the `/codebase-design` skill for the architecture vocabulary (**module**, **interface**, **depth**, **seam**, **adapter**, **leverage**, **locality**) and its principles (the deletion test, "the interface is the test surface", "one adapter = hypothetical seam, two = real"). Use these terms exactly in every suggestion — don't drift into "component," "service," "API," or "boundary."
+- The domain language in `CONTEXT.md` gives names to good seams.
+
+## Process
+
+### 1. Explore
+
+**Scope before you scan — YAGNI.** Deepening a module pays off by making future changes to it easier, so put extra weight on the parts of the codebase that have recently changed. Decide *where* to look before you look:
+
+- If the user named a direction — a module, a subsystem, a pain point — take it, and skip the inference below.
+- Otherwise, walk back a good stretch of the commit history (`git log --oneline`) to find the codebase's hot spots — the files and areas that keep coming up — and let those paths pull your attention first. If the changes are scattered with no clear hot spot, widen the net.
+
+Read the project's domain glossary (`CONTEXT.md`) first.
+
+Then spawn a sub-agent to walk the codebase. Don't follow rigid heuristics — explore organically and note where you experience friction:
+
+- Where does understanding one concept require bouncing between many small modules?
+- Where are modules **shallow** — interface nearly as complex as the implementation?
+- Where have pure functions been extracted just for testability, but the real bugs hide in how they're called (no **locality**)?
+- Where do tightly-coupled modules leak across their seams?
+- Which parts of the codebase are untested, or hard to test through their current interface?
+
+Apply the **deletion test** to anything you suspect is shallow: would deleting it concentrate complexity, or just move it? A "yes, concentrates" is the signal you want.
+
+### 2. Present candidates as an HTML report
+
+Write a self-contained HTML file to the OS temp directory so nothing lands in the repo. Resolve the temp dir from `$TMPDIR`, falling back to `/tmp` (or `%TEMP%` on Windows), and write to `<tmpdir>/architecture-review-<timestamp>.html` so each run gets a fresh file. Open it for the user — `xdg-open <path>` on Linux, `open <path>` on macOS, `start <path>` on Windows — and tell them the absolute path.
+
+The report uses **Tailwind via CDN** for layout and styling, and **Mermaid via CDN** for diagrams where a graph/flow/sequence reliably communicates the structure. Mix Mermaid with hand-crafted CSS/SVG visuals — use Mermaid when relationships are graph-shaped (call graphs, dependencies, sequences), and hand-built divs/SVG when you want something more editorial (mass diagrams, cross-sections, collapse animations). Each candidate gets a **before/after visualisation**. Be visual.
+
+For each candidate, render a card with:
+
+- **Files** — which files/modules are involved
+- **Problem** — why the current architecture is causing friction
+- **Solution** — plain English description of what would change
+- **Benefits** — explained in terms of locality and leverage, and how tests would improve
+- **Before / After diagram** — side-by-side, custom-drawn, illustrating the shallowness and the deepening
+- **Recommendation strength** — one of `Strong`, `Worth exploring`, `Speculative`, rendered as a badge
+
+End the report with a **Top recommendation** section: which candidate you'd tackle first and why.
+
+**Use CONTEXT.md vocabulary for the domain, and the `/codebase-design` vocabulary for the architecture.** If `CONTEXT.md` defines "Order," talk about "the Order intake module" — not "the FooBarHandler," and not "the Order service."
+
+See `.agents/skills/improve-codebase-architecture/HTML-REPORT.md` (path from the repo root) for the full HTML scaffold, diagram patterns, and styling guidance.
+
+Do NOT propose interfaces yet. After the file is written, ask the user: "Which of these would you like to explore?"
+
+### 3. Grilling loop
+
+Once the user picks a candidate, run the `/grilling` skill to walk the decision tree with them — constraints, dependencies, the shape of the deepened module, what sits behind the seam, what tests survive.
+
+Side effects happen inline as decisions crystallize — run the `/domain-modeling` skill to keep the domain model current as you go:
+
+- **Naming a deepened module after a concept not in `CONTEXT.md`?** Add the term to `CONTEXT.md`. Create the file lazily if it doesn't exist.
+- **Sharpening a fuzzy term during the conversation?** Update `CONTEXT.md` right there.
+- **Want to explore alternative interfaces for the deepened module?** Run the `/codebase-design` skill and use its design-it-twice parallel sub-agent pattern.

 # Local Codex Review (pre-push)
@@ -11,17 +11,18 @@ before the PR exists. Use this before `git push` on a non-trivial change.
 
 **Correspondence with CI** — identical:
 - Policy: `REVIEW.md` (severity triage, public-surface checklist, AGENTS.md compliance, test coverage).
-- Model: `gpt-5.6-sol`, `model_reasoning_effort="xhigh"`.
+- Reasoning effort: `model_reasoning_effort="xhigh"`.
 - Output: markdown starting with `## Codex Review`, findings tagged P0 / P1 / P2 with file:line.
 
 **Differences from CI** — local-only:
+- Model is `gpt-6-astra`; CI stays on `gpt-5.6-sol`. Not an oversight to reconcile: `gpt-6-astra` is confirmed on the ChatGPT auth `codex login` uses locally, while CI authenticates with `OPENAI_API_KEY` (`codex-pr-review.yml` prefers it over `CODEX_AUTH_JSON`) and that tier is unverified for the model. Move CI once API access is confirmed, or once CI switches to `CODEX_AUTH_JSON`.
 - Scope is the current branch vs `main` at the merge-base, **including uncommitted changes** (CI reviews a pushed PR diff).
 - Sandbox is `read-only` (CI uses `danger-full-access` on an ephemeral runner). Codex reads the diff and files but cannot modify your working tree.
 - Fresh context is inherent: `codex exec` is a separate cold process, so it does not anchor on the current chat session — the same reason `local-review` insists on a subagent.
 
 ## Prerequisites
 
-- `codex` CLI **>= 0.144.1** installed and authed (`codex login` or `OPENAI_API_KEY`). Older CLIs reject `gpt-5.6-sol` with "requires a newer version of Codex". Upgrade with `npm install --global @openai/codex@0.144.1` (may need `sudo` for a global install). Keep this in sync with the pin in `.github/workflows/codex-pr-review.yml`.
+- `codex` CLI **>= 0.153.4** installed and authed via `codex login` (an `OPENAI_API_KEY` in the environment takes priority and may not reach `gpt-6-astra` — see the model note above). Older CLIs reject the model with "requires a newer version of Codex"; `run.sh` checks the version up front. Upgrade with `npm install --global @openai/codex@0.153.4` (may need `sudo` for a global install). This matches the pin in `.github/workflows/codex-pr-review.yml` — the CLI version is the same on both sides, only the model differs.

+   `/review` (and `/codex`) are **idempotent per head SHA**: if a running or successful review already covers the current head, they skip that agent and post nothing new — the waiter reads the existing verdict for that head, so a skipped agent is *not* a missing one.

 2. **Judge the round.** Codex is mandatory; Claude, Pi and cubic count whenever they posted. Every review starts with one of the three `REVIEW.md` verdicts:

    If any P0/P1 finding is unaddressed or the head moved for reasons other than nit fixes, do **not** post the marker or flip — run another round instead.
 
+### A round that never starts is usually a conflict
+
+The review workflows don't run on a PR that cannot merge, so a round that produces no verdict is
+more often a conflict with `main` than a CI outage. Check before assuming anything is broken:
+
+```bash
+gh pr view <PR_NUMBER> --json mergeable,mergeStateStatus
+```
+
+Resolve by **merging, not rebasing** — a rebase rewrites the head SHA that round verdicts and the
+clean-round marker are keyed to, invalidating work you have already paid for:
+
+```bash
+git fetch origin main
+git merge origin/main
+```
+
+**If that merge changed `backend/ee-repo-ref.txt`, move the EE worktree to match.** The file pins
+the EE commit CE builds against, so a merge that advances it leaves the EE checkout behind what CE
+now expects, and `cargo check --features private` compiles a tree neither you nor CI intends:
+
+```bash
+git -C <ee-worktree> merge "$(tr -d '[:space:]' < backend/ee-repo-ref.txt)"
+```
+
+Push both, then start a fresh round — the head moved, so the earlier verdicts no longer apply.
+
+### Flip, or ask first
+
+A clean round earns the flip; it does not always earn it *unattended*. Judge the blast radius from
+the diff first — `git diff --name-only main...HEAD` answers most of these.
+
+**Ask before flipping** when the change:
+
+- touches `*_ee.rs` (it spans the EE repo through symlinks and has a companion PR)
+- adds a migration under `backend/migrations/`
+- changes `openapi.yaml`, `openflow.openapi.yaml`, or the generated client
+- touches auth, permission, or token paths
+- changes shared worker infrastructure — the job poller, `handle_child`, an executor
+- trips `REVIEW.md`'s "Checklist for new public surfaces"
+
+**Flip without asking** when it is self-contained: a single-file fix, test-only, docs-only, one
+call site, no new public surface.
+
+Unattended (webmux oneshot) there is nobody to ask, so the judgement holds and the action
+degrades: flip the self-contained ones, and leave the rest at a clean draft with a line in the PR
+description saying why — `left in draft: adds a migration, wants a human look before ready`.
+Don't flip a wide-blast-radius change just because the round came back clean, and don't ask a
+question nobody will read.
+
+`AGENTS.local.md` (gitignored, so it may not exist) carries a "PR ready calibration" section
+recording how past ambiguous calls went. Read it before deciding; when a call is still genuinely
+ambiguous, ask, then append the answer there so the next one is less ambiguous.
+
+### When rounds stop converging
+
+Three or more rounds without a clean verdict usually means the change's shape is wrong, not that
+there is an endless supply of independent bugs. The tells:
+
+- findings keep landing in the same files round after round
+- fixing one finding creates the next
+- the findings are about coupling, duplication, or state threaded through many places, rather
+  than logic errors
+
+When that pattern holds, stop running rounds — each one costs a CI cycle and is not going to
+converge. Say plainly that the remaining findings look structural rather than incidental, and
+name the module or seam they cluster around. With a user present, suggest they run
+`/improve-codebase-architecture` over that area: it is slash-only so you cannot invoke it
+yourself, and reshaping the code is a scope change they should choose. Unattended, put the
+diagnosis in the PR description and stop there rather than grinding out more rounds.

 ## When to Run

+Run after **adding or editing** a SQL query in Rust source. Without it, CI fails with:
 ```
 error: `SQLX_OFFLINE=true` but there is no cached data for this query
 ```
 
+**Do NOT run it when a change only *removes* queries.** The cache is already complete for
+CI; all that is left are orphaned entries, which are cosmetic and never break a build.
+Running `prepare` to tidy them risks destroying the cache for no gain. Delete them
+offline instead: for each `.sqlx/query-*.json`, normalize its `query` field (strip `\`
+line-continuations, collapse whitespace) and check whether it still appears in any `.rs`
+file. That detector reports ~48 false positives in a CE checkout — EE queries live in
+`*_ee.rs` symlinks it cannot read — so **filter to the tables your change touched** and
+delete only those.
+
+## Before You Run Anything
+
+1. **Back the cache up.** `prepare` deletes `.sqlx/` *before* regenerating, so any compile
+   failure leaves it gutted (observed: 2350 → 142 entries).
+   ```bash
+   bash .agents/skills/update-sqlx/sqlx-cache.sh backup
+   ```
+   Its state is per-worktree, so a sibling worktree running `prepare` at the same time
+   cannot overwrite your backup.
+2. **Point `DATABASE_URL` at THIS worktree's database.** `prepare` compiles every
+   `sqlx::query!` against the **live** database. Another worktree's DB lacks your
+   migrations, so every new-table query fails and takes the cache down with it. The
+   symptom is `relation "<your_new_table>" does not exist` — that is a wrong
+   `DATABASE_URL`, not a broken query. See AGENTS.md → "Per-worktree ports and database".
+
+## Queries Inside Tests Need `--all-targets`, Which Fails In A CE Checkout
+
+`prepare` only caches queries in code it compiles, and `--workspace` alone does **not**
+compile test targets. A `sqlx::query!` inside `tests/*.rs` therefore gets no entry, and CI
+fails on the test target with the usual "no cached data" error even though the lib built
+clean. `SQLX_OFFLINE=true cargo check --workspace --all-targets` is what reproduces it.
+
+Adding `--all-targets` caches them — and, in a CE checkout, **aborts partway through**:
+`backend/tests/otel.rs` imports `windmill_common::otel_ee`, which exists only behind the
+`private` feature, so the compile dies after `prepare` has already emptied `.sqlx/`.
+Observed: 2435 → 4 entries, `error: cargo check failed with status: exit status: 101`.
+
+Do not fight it — the abort is a pre-existing EE gap, not something your change caused.
+Take the entries you need and put the backup back:
+
+```bash
+bash .agents/skills/update-sqlx/sqlx-cache.sh backup
+
+cd backend
+DATABASE_URL=<this worktree's db> \
+  cargo sqlx prepare --workspace -- --workspace --features all_sqlx_features --all-targets
+# expected to fail; it still wrote the entries it got to before dying
+cd ..
+
+bash .agents/skills/update-sqlx/sqlx-cache.sh newq      # prints each added query
+bash .agents/skills/update-sqlx/sqlx-cache.sh restore   # backup back, added entries grafted on
+```
+
+**Read what `newq` prints before running `restore`** — it shows each added entry's `query`
+field, and every one should be yours. The set is small (one per new test query); anything
+else in there means the run got further than you think.
+
+Then verify both targets, since the lib passing says nothing about the tests:
+
+```bash
+SQLX_OFFLINE=true cargo check --workspace --features all_sqlx_features   # lib
+SQLX_OFFLINE=true cargo check -p <your-crate> --all-targets              # tests
+```
+
 ## The Problem
 
 `cargo sqlx prepare --workspace` **deletes all existing cache files** and regenerates only the ones found in the current compilation. If you don't compile with every feature flag (especially `private` for EE files), you will **silently delete EE query caches**, breaking CI for enterprise tests.
@@ -68,7 +131,16 @@ But if it fails with EE compilation errors, use the safe procedure above.
 
 - **Never** run `cargo sqlx prepare --workspace` with only OSS features and commit the result — it will delete EE caches.
 - **Never** set `SQLX_OFFLINE=true` for local `cargo sqlx prepare` — use a live database per CLAUDE.md. (CI runs with `SQLX_OFFLINE=true`, which is why the cache must be complete.)
+- **Never** run `prepare` without a `.sqlx` backup, or against a `DATABASE_URL` you have not confirmed belongs to this worktree.
+- **Never** run `prepare` at all for a removal-only change.
 - **Never** skip the verification step (step 4 above).
+- **Never** leave a `--all-targets` run's output in place after it aborts — it is a
+  near-empty cache. Restore the backup and graft on only the entries you verified.
+
+Step 4 compares against `origin/main` because step 1 restored from it, so the two agree.
+If you did **not** run step 1 — auditing a branch's cache on its own, say — compare
+against `git merge-base HEAD origin/main` instead: `origin/main` advances, so its newer
+entries would read as losses on your branch.

+# Anything else makes no decision (exit 0) and falls back to the normal permission flow, except

+# lib-guarded-verb.sh).
+#
+# The command is read one segment at a time, so chaining and line breaks carry no weight of
+# their own: `cd /tmp/scratch && mv /tmp/a /tmp/b` is proved on the operands of the `mv`. A
+# decision covers the whole command line, so `allow` is emitted only when every segment is one
+# of these verbs proved here or a `cd` that resolved, AND exactly one of them writes (see the
+# gate at the foot of this file — an earlier write can change what a later operand means). A
+# line that mixes a proven op with some other command makes no decision instead and leaves that
+# line to the normal permission flow, rather than waving an unexamined command through with it.
+#
+# This is a hook rather than an allow rule because permission rules match a command prefix, so
+# they can only constrain the FIRST operand. `cp /tmp/x ~/.zshrc` matches a `cp /tmp/` prefix,
+# and requiring every operand is the point.
+#
+# One operation may not straddle two roots, sources included, and a sibling checkout is a
+# different root — `path_class` names the git tree, not just its kind. A copy out of a checkout
+# into /tmp would be a read-exfiltration path around the `Read(**/secrets/**)` / `Read(**/*.pem)`
+# deny rules, since the content lands where `Read(/tmp/**)` allows it to be read back, and one
+# out of a repo the Read tool is not confined to would do the same for that repo. Keeping every
+# operand of one operation inside a single root closes both without restating those rules here.
+# The checkout root itself is what makes an in-repo `mv` or `chmod` auto-allowable: deleting a
+# file there has never prompted, and moving or chmod-ing one is not the graver act.
+#
+# Deny-by-default tokenizing, in the same spirit as guard-rm-outside-tmp.sh: every path token
+# must consist only of alphanumerics and `. _ / -`, the one exception being the leading `~/` or
+# `$HOME/` that `expand_home_prefix` rewrites first. That set contains none of the characters
+# bash uses for quoting, expansion, or command separation ($ ` ~ { } ( ) ' " \ ; & | < >), nor
+# any glob character, so all of those forms fail by construction. `canon_path` then resolves
+# `..` and existing symlinks, so `/tmp/link` pointing at /etc/passwd is caught.
+#
+# `tar` and `unzip` keep the stricter rule — /tmp only, and absolute operands only — because
+# their positional grammar makes a bare word ambiguous: `tar P -xf ...` is --absolute-names,
+# not a file named P, and resolving it as a path would put an option in a root and allow it.
+# The other five take relative operands, resolved against the working directory that `cd`
+# tracking maintains, since for those a bare word really is a path (a GNU option starts with
+# `-`, and the option allowlist below rejects the ones that would change symlink handling).
+#
+# `tar` and `unzip` get their own parser: their write destination arrives as a flag VALUE
+# (`-C`, `-d`) rather than a positional, and a bundle like `-xzf` consumes the token after it.
+# Flags are an allowlist, not a denylist, so `-P` / `--absolute-names` — which turn off tar's
+# refusal to extract `..` and absolute member paths — defer rather than needing enumeration.
+# Extraction additionally requires an explicit destination under /tmp, or a working directory
+# already under /tmp, since otherwise members land in the project checkout.

+# Residual risk accepted: an archive whose members include a symlink pointing out of /tmp

+# Any other command that runs `rm` gets an explicit `ask`, which is the ordinary permission
+# prompt and the only one `rm` gets (see lib-guarded-verb.sh); a command that runs no `rm` at

+#
+# The command is read one segment at a time, so chaining and line breaks carry no weight of
+# their own: `rm -f /tmp/a && rm -rf /tmp/b` is two deletes, each proved on its own operands.
+# A decision covers the whole command line, so `allow` is emitted only when every segment is
+# an `rm` this guard proved or a `cd` it could resolve. A line that mixes a proven `rm` with
+# some other command makes no decision instead and leaves that line to the normal permission
+# flow: the delete is not what needed a prompt, and waving the rest of the line through with
+# it would turn a trailing `rm -f /tmp/x` into a way to auto-approve anything.
+#
+# Deny-by-default: every token must consist only of a safe character set (alphanumerics,
+# `. _ / -` and glob chars `* ? [ ]`), the one exception being the leading `~/` or `$HOME/` that
+# `expand_home_prefix` rewrites first. That set contains none of the characters bash uses for
+# quoting, expansion, or command separation ($ ` ~ { } ( ) ' " \ ; & | < >), so those forms

+# Which targets those roots cover, and the tradeoff they rest on, is `path_class` in

 - Return a markdown PR comment starting with `## Pi Review`.
 - Tag each finding with a severity (P0 / P1 / P2), file path, and line number when known confidently.
 - Output ONLY the final review markdown — no preamble, no thinking, no tool transcripts.
+
+# Before you settle on a verdict
+
+`REVIEW.md` tells you to discard findings you are not confident in. That rule exists to suppress noise, not to license a quick approval. Review in two passes:
+
+1. Enumerate every candidate defect you notice, without judging any of them yet.
+2. Take each candidate and try to prove it is real: read the surrounding code, check the caller, check the error path. Keep it, or dismiss it for a specific reason.
+
+A "Good to merge" verdict must be accompanied by a "Considered and dismissed" section listing each candidate from pass 1 with the concrete reason it is not a finding. If that section would be empty, pass 1 was skipped: go back and do it.
+
+Facts cut both ways. If you notice that a cached value can be multiple megabytes, that a lock is held across an await, or that a new parameter is caller-controlled, that observation is a candidate for pass 2 even when the surrounding code looks deliberate. Do not narrate such a fact as evidence that the code is fine without first checking whether it is a bug.

+   expected, not a last resort. A few examples, not a closed list: drive the UI with the Playwright
+   MCP, run a real job of the kind you touched, restart the backend with the cargo features the
+   path needs (`backend/AGENTS.md`), put a stub in front of an upstream, start MinIO for an S3
+   path, plant state with SQL, exercise it through the `wmill` CLI. If the path you need has no
+   obvious way in, invent one rather than skipping it; `docs/` carries recipes for several areas.
+   If it needs a credential or a third-party account, ask for one rather than skipping the test or

 ## Documentation
 
 - **Validation**: `docs/validation.md` — what checks to run based on what you changed
+- **Unreleased SDK changes**: `docs/wac-sdk-e2e.md` — exercising a client change on a real worker
+- **Agent workers**: `docs/agent-worker-e2e.md` — building and running one locally. An agent
+  reaches the DB only through the API, so `Connection::Http` paths are never taken by a plain
+  `cargo run`; a normal build cannot start one at all.
 - **Enterprise**: `docs/enterprise.md` — EE file conventions and PR workflow
+- **Product telemetry**: `docs/feature-telemetry.md` — when to instrument a new feature with
+  `feature_usage`, and the four-step recipe. An unregistered `(feature, kind)` pair is dropped
+  silently, so frontend-only instrumentation records nothing.
 - **Backend patterns**: use the `rust-backend` skill when writing Rust code
 - **Frontend patterns**: use the `svelte-frontend` skill when writing Svelte code. Do NOT edit svelte files unless you have read that skill.
 - **Frontend UUIDs**: do not call `crypto.randomUUID()` in frontend code. Import `randomUUID` from `$lib/utils/uuid` instead.
-- **Code review**: review the current PR or branch against the shared review policy in `REVIEW.md` (severity triage, public-surface checklist, AGENTS.md compliance, test-coverage assessment). The skill at `.agents/skills/local-review/SKILL.md` orchestrates it. All three CLIs auto-discover the same SKILL — Claude reads `.claude/skills/` (symlinked to the canonical `.agents/skills/` file), Codex and Pi read `.agents/skills/` directly. Invoke with `/local-review` in Claude Code, `$local-review` (or `/skills` selector) in Codex, or `pi --skill local-review` / `/skill:local-review` in Pi.

The CLI docs the agents use to operate `wmill` are derived from the source — stale generated files give agents the wrong flags.
+- **Session recorder**: `frontend/src/lib/components/recording/` is also the recorder `wmill app dev --recording` serves, vendored into the CLI as `cli/src/commands/app/devRecorderBundle.gen.ts`. After changing `rawAppSnapshot.ts` or `rawAppRecording.svelte.ts`, run `bun run gen:dev-recorder` from `cli/` (`cli/test/dev_recorder_bundle_unit.test.ts` fails otherwise).
+- **Raw-app policy**: `frontend/src/lib/components/raw_apps/rawAppPolicy.ts` also derives the policy the server's raw-app deploy stores, vendored into the bundle job as `backend/windmill-api/src/apps_raw_policy.gen.js`. After changing it or anything it imports, run `bun run gen:app-policy` from `cli/` (`cli/test/app_policy_bundle_unit.test.ts` fails otherwise). It rides in the job rather than being read from the CLI the job runs because the images install `windmill-cli` unpinned, so an image can carry one older than its server.
 
 ## Dev Environment
 
+> **In a git worktree, the ports and database below are NOT the ones to use.** Each
+> worktree gets its own backend port, frontend port and Postgres database, so the
+> defaults in this section apply only to a plain single checkout. **Discover the real
+> values before running anything** — see "Per-worktree ports and database" below.
+
+**Check whether they are already running before starting anything.** In a webmux worktree
+(`$WEBMUX_WORKTREE_PATH` is set) the backend and frontend are already up in sibling tmux panes —
+use those, don't spawn your own. `tmux list-panes -t "$(tmux display-message -p -t "$TMUX_PANE"
+'#{window_id}')" -F '#{pane_index} #{pane_current_command}'` shows what is running; read its log
+with `tmux capture-pane`, and see `backend/AGENTS.md` to restart it with different cargo features.
+A second server started in your own shell fights the first one for the port. The commands below
+are for a plain checkout with nothing running.
+
 - **Backend**: `cargo run` from `backend/` (API at http://localhost:8000)
-- **DuckDB local jobs**: before running DuckDB scripts locally, build the FFI shared library with `cd backend/windmill-duckdb-ffi-internal && ./build_dev.sh`. Re-run it after clean builds or when `backend/target/debug/libwindmill_duckdb_ffi_internal.*` is missing. The bundled DuckDB compile (~2min) is cached in a per-user dir shared across worktrees, so a fresh worktree reuses it and the build is near-instant.
-- **Data pipelines (DuckLake) from source**: a plain `cargo run` (even `--features quickjs`) advertises a `duckdb` worker tag but **cannot** execute DuckDB scripts and has **no** working S3 proxy (DuckLake writes 404). Build CE DuckLake with `cargo run --features quickjs,duckdb,parquet,private` (add `,python` for Python scripts, `,enterprise,license` for EE) **and** build the FFI (bullet above). See `backend/CLAUDE.md` → "Running data pipelines (DuckLake) from source" for the exact feature sets and the two feature-gate gotchas.
 - **Frontend**: `REMOTE=http://localhost:8000 npm run dev` from `frontend/` (port 3000+)
 - **DB**: `psql postgres://postgres:changeme@localhost:5432/windmill`
 - **Login**: `admin@windmill.dev` / `changeme`
 - **Instance settings**: navigate to `/#superadmin-settings`
 - **Migrations**: use `cargo sqlx migrate add -r <name>` from `backend/` to create new migrations (never generate timestamps manually)
 
-## Verifying Frontend Changes
+### Per-worktree ports and database
 
-After modifying frontend code, drive the running dev server with the **Playwright MCP** to verify the change in a real browser — don't claim a UI change works without exercising it.
+In a webmux worktree the authoritative values live in
+`$(git rev-parse --git-dir)/webmux/runtime.env` — `BACKEND_PORT`, `FRONTEND_PORT`,
+`DATABASE_URL`, `CARGO_FEATURES`, `WM_DB_NAME`. Every pane sources it at startup. Read that
+first: it is not a `.env*` file, so the repo's secret-file read rules don't stand in the way.
 
-Two MCP servers are registered in `.mcp.json`:
-- `playwright` — headless Chromium, default for devboxes (no display required)
-- `playwright-headed` — windowed Chromium, when a display is available
+In a plain checkout, fall back to `.env` / `.env.local` (repo root) and `backend/.env`.
 
-**One-time setup:** run `npx playwright install chromium` to download the browser binary (Playwright won't fetch it automatically on first use).
+Each worktree gets a **brand-new database**, created and migrated from scratch by the post-create
+hook. It is not a copy of the main dev instance: you get the `admins` workspace, the
+`admin@windmill.dev` superadmin, the license key copied from the base database, and whatever the
+migrations seed — and none of your own workspaces, scripts, flows or apps. Create whatever a test
+needs. Cloning the base `windmill` database instead is
+opt-in per project via `WM_CLONE_DB` in `.webmux.yaml`; read the note there before turning it on.
 
-Typical flow:
-1. Ensure backend (`cargo run`) and frontend (`REMOTE=http://localhost:8000 npm run dev`) are running
-2. `mcp__playwright__browser_navigate` to the relevant page (login at `admin@windmill.dev` / `changeme`)
-3. `mcp__playwright__browser_snapshot` to inspect the accessibility tree (preferred over screenshots for reading the DOM)
-4. `mcp__playwright__browser_click` / `browser_fill_form` / `browser_type` to interact
-5. `mcp__playwright__browser_take_screenshot` for visual confirmation
-6. `mcp__playwright__browser_console_messages` / `browser_network_requests` to surface errors
+The database is named after the **worktree directory, not the branch** (`scripts/worktree-common.sh`):
+`windmill_` + the directory basename with `-` → `_`, which Postgres then truncates at 63
+characters. Branch `hugo/win-2340-ai-agent-evals-standalone-agent-runs-and-eval-datasets` sits in
+a worktree directory named `win-2340-…`, so its database is
+`windmill_win_2340_ai_agent_evals_standalone_agent_runs_and_eval` — no `hugo_`, and the tail
+chopped. Take `WM_DB_NAME` from `runtime.env` instead of reconstructing the name. Read those, or
+discover from what is already running:
 
-**Attach the screenshots to the PR.** For any change under `frontend/`, embed screenshots of the affected UI in the PR body — the `pr` skill requires this and carries the upload recipe.
-
-If you cannot exercise a UI change (no dev server, etc.), say so explicitly rather than claiming success.
-
-## Banned Patterns
-
-### `$bindable(default_value)` on optional props
-
-Using `$bindable(default_value)` on props that can be `undefined` is **banned**. This pattern causes subtle bugs because the default value masks the `undefined` state.
-
-**Bad:**
-
-```svelte
-let { my_prop = $bindable(default_value) }: { my_prop?: string } = $props()
+```bash
+psql postgres://postgres:changeme@localhost:5432/postgres -tAc \
+  "select datname from pg_database where datname like 'windmill%'" | grep "$(git branch --show-current | tr - _)"
+# the port the frontend actually proxies to (REMOTE of this worktree's vite):
+for p in $(pgrep -f vite); do case "$(readlink /proc/$p/cwd)" in *"$(basename "$(git rev-parse --show-toplevel)")"*)
+  tr '\0' '\n' < /proc/$p/environ | grep -E '^REMOTE=|^PORT=';; esac; done
 ```
 
-**Correct alternatives:**
+Getting these wrong is not a cheap mistake:
 
-1. **Use `$derived` with nullish coalescing** — handle the potential `undefined` at the usage site:
-
-   ```svelte
-   let { my_prop = $bindable() }: { my_prop?: string } = $props()
-   let effective_value = $derived(my_prop ?? default_value)
-   ```
-
-2. **Create a `useMyPropState()` helper** — encapsulate the undefined-handling logic in a reusable function and call it higher in the component tree, so the child component always receives a defined value.
+- **`DATABASE_URL` pointed at another worktree's database silently destroys the sqlx
+  cache.** `cargo run` and `cargo sqlx prepare` both compile `sqlx::query!` against the
+  **live** database, so the wrong one fails with `relation "<your_new_table>" does not
+  exist` — and `prepare` deletes the whole `.sqlx/` directory *before* it fails, leaving
+  it gutted. Always `cp -r backend/.sqlx <tmp>/sqlx_backup` first (see the `update-sqlx`
+  skill).
+- **The frontend proxies to its own worktree's backend port, not 8000.** Starting a
+  backend on the wrong port leaves the UI up but every API call 502s, which reads like an
+  application bug rather than a misconfiguration.
+- **Kill backends by pid scoped to this worktree's cwd** (`readlink /proc/<pid>/cwd`),
+  never `pkill -f target/debug/windmill` — that kills every sibling worktree's backend.
+  Beware that a `pgrep -f "<pattern>"` in a shell whose own command line contains
+  `<pattern>` matches the shell itself.

 ## Core Principles
 
 - **MUST `outline` before `Read`** on unfamiliar files — then `body` or `Read` with offset/limit for specifics
+- **Scratch stays outside the checkout.** Temp scripts, data dumps, cache backups and
+  screenshots go in the session scratch directory or `/tmp`, so nothing temporary can end up
+  committed. Write the paths in `rm`/`mv`/`cp` out literally: a PreToolUse hook proves each
+  operand, and auto-allows deletes, moves, copies and mode changes under `/tmp`, inside a git
+  checkout under `$HOME`, or in the Playwright MCP browser caches (`~/Library/Caches/ms-playwright`
+  and `ms-playwright-mcp`, `~/.cache/…` on Linux), as long as one operation stays within a single
+  root — a sibling checkout is a root of its own (`tar` and `unzip` stay `/tmp`-only). Chain
+  deletes freely, each proved on its own operands, but keep writes to one per line, name the
+  destination rather than a directory to drop it in, and put anything else on its own line: a
+  command the hook does not prove drops the whole line back to the normal permission flow. A
+  leading `~/` or `$HOME/` is expanded and proved; a quoted operand, any other `$VAR`, a redirect,
+  a `$(…)`, a relative `cd`, or a wrapper like `xargs rm` cannot be, and that deferral is what
+  turns a cleanup into a prompt.
+- **Change files with Edit/Write, not the shell.** `sed -i`, `cat > file <<'EOF'` and inline
+  `python3 - <<'PY'` scripts put an edit through the PreToolUse guards and the permission
+  classifier, which match `Bash` and nothing else, so a routine edit arrives as a prompt. Bash
+  stays right for running things — tests, builds, git, one-off queries.
 - Search for existing code to reuse before writing new code
 - Follow established patterns in the codebase
 - Keep changes focused — don't refactor beyond what's asked
+- **A simpler design found late is still the design.** Work already spent is not an argument
+  for a shape, and neither is a clean review round, a passing suite, or a long PR thread. The
+  signal to stop and re-derive rather than patch again is a change that keeps growing to defend
+  its own structure: each review finding fixing an assumption the previous fix broke, the same
+  class of bug reappearing somewhere new, or most of the diff being consequences of one early
+  choice rather than the thing you set out to do. When that happens, say plainly what the
+  simpler design is and what switching costs — a migration, a review cycle restarted from zero,
+  work discarded — and let the user decide. Do not keep paying down the harder one because it
+  is nearly finished, and do not present the accumulated cost as a reason to continue.
 - **Ship only the tests the PR needs.** A committed test must pin behavior a future change could plausibly break, and be the smallest setup that exercises the new logic. While developing, write as many exhaustive tests and do as much manual testing as you need to convince yourself the change works — then remove that scaffolding before marking the PR ready, keeping only the essential regression guard(s). A test that merely re-exercises pre-existing behavior, or needs elaborate fixtures to assert something trivial, is scaffolding: delete it. If nothing meaningful is left to guard, ship no test rather than a ceremonial one.
 - **Comments record constraints, not narration.** Write a comment only for what the code can't show: why a non-obvious approach is required, what breaks if it's "simplified" away. State each invariant once, at the place where someone would break it, in ≤4 lines. Don't describe what the next line does, don't repeat the same rationale at multiple sites, and don't address the PR reviewer (justifying a change belongs in the PR description, not the code). Reference nothing ephemeral — no numbered steps from your dev flow, no "the poller / the test does X" scaffolding, no transient state that won't exist for the next reader; keep only the essential, durable rationale. Describe the code as it is, never its drafting history: "we no longer do X", "unchanged behavior", "instead of the previous approach" are meaningless to a reader who never saw the earlier iteration — before finishing, reread your comments as if the current state is the only state that ever existed.
 - **Never attribute work to a specific customer, account, or "requested by a customer" in repo-tracked content** (PR descriptions, commit messages, code comments, docs). Describe changes by their technical motivation instead.

+# Windmill
+
+Open-source platform for internal tools, workflows, API integrations, background jobs and UIs. This file pins the vocabulary that is specific to Windmill's domain, so that code, docs and reviews name the same thing the same way.
+
+## Language
+
+### Flows
+
+**Step**:
+One node of a flow — the unit a user selects in the graph and configures in the right-hand panel. Typed as `FlowModule` in code.
+_Avoid_: module (ambiguous with the architectural sense), node, action
+
+**Step setting**:
+A per-step runtime option stored on the step itself: retries, error handling, timeout, concurrency limit, priority, cache, debounce, early stop, skip, suspend, sleep, lifetime. Distinct from the step's inputs and its code. The panel that edits them is the **run settings** tab; a single setting is still a step setting.
+_Avoid_: advanced setting, step config, flow option
+
+**Configured**:
+Said of a step setting whose config object is present on the step. Deliberately not the same as "would change the runtime's behaviour" — a setting can be configured and still be a no-op (`sleep` of `0`). Every surface that answers "is this setting on?" answers it this way.
+_Avoid_: enabled, active, effective
+
+**Trigger step**:
+The first step of a polling flow. It runs on a schedule and returns the items found since its last run; an empty return means there is nothing to process and the flow stops early, marked skipped rather than failed.
+_Avoid_: poll script, trigger node, schedule step
+
+**Default predicate**:
+The `stop_after_if` expression seeded onto a trigger step at creation, encoding what "nothing new" looks like. One value, owned in one place, shared by every path that creates a trigger step.
+
+**Connect**:
+Arming an input so that the next property picked fills it. A property can be picked from the prop picker or, when the panel is docked beside the graph, by clicking a step node's output. At most one input is armed per panel, so a pick always has exactly one destination.
+_Avoid_: link, bind, plug (the icon is a plug; the action is connecting)
+
+**Step input**:
+One argument of a step, edited in the step's input form. Its prop picker is a pane beside the form, always visible, so previous results can be browsed without connecting.
+_Avoid_: argument field, param
+
+**Expression input**:
+Any other place a property can be picked into: the loop iterator, skip and early-stop predicates, the retry condition, a branch predicate, timeout. Its prop picker opens in a popover from the connect button rather than taking a pane.
+_Avoid_: JS field, code input
+
+### Permissions
+
+**Member**:
+A user or group granted a role on a folder, a group, or an item's extra ACL. The list of them is
+"Members (n)" everywhere it is shown, and one is added with "Add member".
+_Avoid_: participant, collaborator, owner, ACL entry, permission (that names the concept, not the people)
+
+**Role**:
+The access level a member holds: viewer, writer or admin on a folder; member or admin on a group.
+Viewers read, writers also edit, admins also manage the members. A group role of **manager** —
+manages the group without belonging to it — is a legacy state the UI shows and can leave, but
+offers no way to enter.
+_Avoid_: permission level, access level, rank
+
+**Owner**:
+Reserved for the path prefix that says where an item lives — `u/alice` or `f/team`. A folder's
+`owners` column in the database is its admin members; call those admins, never owners, in the UI.
+_Avoid_: using "owner" for a folder admin

Not counting the init and periodic scripts means they run again on every restart: an init script's runtime is added to the latency of every batch of that many jobs, and a periodic script fires once per process start whatever its interval says. The worker's shell in the workers page also starts backed off rather than after the two minutes it otherwise takes, since a process due to be recycled cannot count on living that long: the first command of a session can wait up to 15s, later ones are immediate. For deployments that isolate executions by process lifetime rather than with nsjail; note that a container restart resets the process, not the container filesystem, so caches and `/tmp` survive it. The worker name is then derived from the hostname instead of being random, so the restarted worker keeps its row in the workers list (an agent worker keeps the row but restarts its job count).

+Global initial fixtures can seed the session's `artifacts` — `{ name, versions: [{ content,
+note? }], role?, approvedVersion? }`, oldest version first, so the artifact starts with the
+history `list_artifact_versions` reports — and the `previewTabs` open in its side panel, for
+cases that run with `runtime.sessionChat: true`. A tab entry names one destination and may
+be the `active` one:
+
+```json
+"previewTabs": [{ "artifact": { "name": "Onboarding plan", "version": 2 }, "active": true }]
+```
+
+`page` (`{ href, label }`) and `item` (`{ kind, path }`) tabs work the same way. Tabs are
+driven by the production tab model, so `open_preview`, `get_preview_status` and
+`close_page` really open, report and close them, and a `version` is the pin a reader
+chose in the artifact's version picker — which only `get_preview_status` reports.
+
+Global initial fixtures can seed `workspace.variables` with
+`{ path, value, is_secret, description?, labels?, ws_specific? }` entries so cases can
+read and edit variables that already exist in the workspace. The mock mirrors the real
+`get_variable`, **decrypt-by-default included**: a secret's `value` is withheld only
+when the caller explicitly passes `decryptSecret: false`, and omitting the flag returns
+the decrypted value, exactly as against a real backend. The chat's read path passes
+`decryptSecret: false`, so a case can verify it never invents a value it was not shown.
+Seed a recognizable secret (the existing fixture uses `sk_live_do_not_leak_me`) and
+assert it via `valueExcludes` to catch a leak.

+recorded call to that tool may pass the field at all (an explicit `null` counts as
