* feat(pipeline): local development for data pipelines (CLI --local + pipeline dev preview) Add the local edit→preview→run loop for data pipelines (folders of `// pipeline` scripts), the analog of `wmill dev` / `wmill app dev`, usable from a code editor or an agentic loop — without deploying. No backend changes: full body inference comes from the same wasm the frontend uses (windmill-parser-wasm-asset), which returns assets + pipeline annotations in one call; local runs reuse runScriptPreview with _wmill_skip_asset_dispatch. - localGraph.ts: wasm-backed working-tree → asset-graph builder (the enabler) - pipeline show/run --local; new pipeline docs (PIPELINE.md/AGENTS.md) subcommand - pipeline dev watcher + /pipeline_dev page (PipelineDevView) rendering the same PipelineGraphEditor from the pushed local graph, run via preview - cascadeRun.ts: reusable run primitives extracted from the route page - regenerated CLI agent docs See docs/pipeline-local-dev.md for the full design, test steps, and handoff TODOs. The live `pipeline dev` browser preview is implemented but not yet stack-verified.

The CLI's wasm therefore never emitted `// materialize`, so the producer had no output edge and showed disconnected from its `// on` consumers. Bump the CLI to 1.740.0 (matching the frontend) and translate the parsed materialize target into the producer's write edge + materialize_target, mirroring frontend resolveGraph.ts. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): harden local-dev CLI (bare-.sql crash, defaultTs, docs clobber) Review fixes, complementary to the dev-preview/materialize/multi-root work already on the branch (none overlap those commits): - localGraph: a bare `.sql` (no dialect) made inferContentTypeFromFilePath throw and abort the whole graph build — and wedge `pipeline dev` at startup. Skip the unclassifiable file instead. Also map `bunnative` → parse_assets_ts and add ruby/rlang/nu/powershell to the `#`-comment fallback. - show/run/docs/dev: thread the resolved `wmill.yaml` defaultTs into the graph builder so `.ts` infers under the workspace's runtime (bun vs deno) instead of always bun — `opts.defaultTs` was always undefined (no such CLI flag). - dev: wrap the startup graph build so a half-written file can't abort the watcher. - docs: don't clobber a user-authored AGENTS.md/CLAUDE.md — only (over)write the pointer when absent or already a generated `@PIPELINE.md` pointer. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): bind dev WS to loopback + local-graph regression tests - pipeline dev WS broadcast the folder's full script source (scripts[].content + temp_script_refs) unauthenticated on 0.0.0.0:3201 — bind 127.0.0.1 so it's not LAN-reachable (webview localhost + SSH/devbox port-forward still work). - Add regression tests for the just-landed local-graph fixes: bare .sql is skipped (was a build/dev-startup crash), defaultTs threads into .ts runtime inference (bun vs deno), and #-comment languages (ruby) use the # annotation fallback. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(pipeline): --frontend flag for pipeline dev page origin wmill pipeline dev opens <remote>/pipeline_dev, but that route only exists in this build's frontend, so it 404s against a remote whose deployed frontend predates it. --frontend <origin> points the page at a locally-run frontend (REMOTE=<remote> npm run dev) while the API/token still target the remote — enabling the live preview against a real backend before the PR is deployed. No behavior change when omitted. Regenerated CLI agent docs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): WS session token + details-pane live-reload refresh Addresses CI review (Codex/Pi/Claude): - dev WS: a browser tab could open ws://localhost:<port>/ws and receive the folder's full source (browsers don't enforce same-origin on WS, loopback bind alone doesn't help). Gate the upgrade on an unguessable per-session token carried in the dev-page URL (verifyClient → 401 without it). Verified: no-token/bad-token connections get 401 with no bundle. - details pane: scriptRes keyed on [workspace, selection, draftScript] didn't re-run on a pipeline dev live-reload (same selection), so the open pane showed stale source. Thread a localScriptsVersion (the pushed bundle) into the key. Verified: editing a selected node's file updates the pane source without reselect. - docs/pipeline-local-dev.md: refresh the stale 'not yet exercised' status + done TODOs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): emit volume: annotation assets in local dev graph Addresses CI review (Codex P1 / Pi P1): the wasm body parser doesn't surface `// volume: <name>` annotations — the frontend (infer.ts:parseVolumeAnnotations) and backend (asset_inference.rs) parse them separately and merge as rw volume assets. localGraph didn't, so a `# volume: cache` producer had no write edge and showed disconnected from its `// on volume://cache` consumer (and pipeline run --local wouldn't schedule downstream). Mirror the leading-comment-block scan (SQL excluded, matching both reference parsers) and merge into inferScriptAssets. Regression test added; verified producer -> volume://cache -> consumer connects. Also (Codex P2): docs/pipeline-local-dev.md manual browser URL omitted the new ws_token param — without it the WS upgrade is rejected and the page sits disconnected. Doc now says to copy the URL the CLI prints (carries wm_token + ws_token) and recommends --frontend. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): runAll excludes event roots + review polish Addresses CI review (Codex P1, Claude P2/P3): - pipeline run runAll: derive the whole-pipeline selection from validStarts + descendants instead of all runnables, so an unqualified 'pipeline run <folder>' no longer fires event-trigger roots (kafka/mqtt/…) with empty args/side effects. Verified: a kafka root is excluded from the plan. - cascadeRun.ts runBoundedCascade: use buildLineageDownstreamMap (read-aware) so a pure-reader runs after its producer, and return cyclic — parity with the route page's bounded run (the file is meant to be THE shared correct primitive). - PipelineGraphEditor: storedRightPaneSize starts at 0 so the orientation-aware default (55% stacked / 40% side-by-side) actually applies on first open. - localGraph fallbackParse (go/bash): scan only the leading comment header (no body-comment phantom triggers) and strip key=value options from the asset URI; regression test added. - docs: reject '..' in the folder arg (it writes files under f/<folder>). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): route local previews to the // tag worker Addresses CI review P1: the local graph/bundle dropped the parsed `// tag`, so a node annotated `// tag gpu` ran on the default worker in both `pipeline run --local` and `/pipeline_dev`, while the deployed pipeline routes it to that worker tag. Carry the tag through LocalScript / the pushed bundle / LocalScriptContent and pass it to runScriptPreview at all three launch sites. Verified: a duckdb node tagged `bash` produces a job tagged `bash`; regression test added. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): add asset partitions/schemas routes to OpenAPI, use generated client The ducklake asset panels (PartitionStatusGrid, SchemaHistoryPanel) hit /assets/partitions and /assets/asset_schemas via raw fetch with cookie-only auth, because those backend routes were never added to openapi.yaml so the generated client had no methods for them. On /pipeline_dev (token-via-URL, no session cookie) the raw fetches 401'd. Add both GET routes + MaterializedPartition/AssetSchemaVersion schemas to openapi.yaml and call them through AssetService, which injects the bearer token, types, and cancellation automatically. Verified: Partitions + Schema tabs load in /pipeline_dev. (backfill stays a raw fetch — it's an EE-only route not in the OSS spec — with the token added inline.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(cli): regenerate bun.lock for windmill-parser-wasm-asset package.json / package-lock.json carry windmill-parser-wasm-asset@1.740.0 but the tracked bun.lock (the CLI installs/builds/tests via bun) was stale, so fresh bun installs would resolve a different graph than the committed lock. Regenerated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): show asset producer + its runs in the dev-preview panel Selecting a ducklake/asset node in /pipeline_dev showed 'No producer for this asset' because selectionProducers wasn't passed (it's derived from the deployed graph on the route page, absent here). Compute it from the local graph's w/rw write-edges (incl. the // materialize target) and pass it through, mirroring the route page — so the panel shows the producing script and its (preview) runs, including data-test failures. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): carry annotation metadata onto local-graph runnables The local graph emitted only path/usage_kind/in_pipeline/materialize_target per runnable, so /pipeline_dev and pipeline show --local weren't the same surface as the deployed graph for annotated scripts — missing the badges/lineage the shared canvas renders. Map the wasm-parsed partition_kind, freshness, tag, retry, data_tests, column_lineage, and materialize_strategy (derived append/merge/replace) onto each runnable, mirroring the deployed AssetGraphRunnableNode. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): exclude event handlers that are lineage descendants from runAll The runAll guarantee ('never fires an event handler with empty args') only held for event ROOTS — validStarts excludes them, but runAll then unions in descendants(dag, start), so a kafka/mqtt/... handler that also reads an upstream pipeline asset (a lineage descendant of a valid start) still landed in the plan. Add eventTriggerScripts() and subtract it from the selection after the descendant union. +unit test. Also: docs/pipeline-local-dev.md recipe used 'pipeline docs demo_pipeline' without --local (default queries the deployed graph → hits the empty hint); add --local. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): whole-pipeline run cuts at event handlers (drop their downstream too) The prior runAll fix subtracted event handlers from the selection but left their downstream: for manual_root → asset_x → kafka_handler → asset_y → consumer, deleting only kafka_handler left consumer selected, and topoOrder then ran it as a root with missing/stale event-derived inputs. Replace the descendant-union+delete with reachableCutting(dag, validStarts, eventHandlers): traverse from valid starts but treat event handlers as cut points, so a node reachable ONLY through an event handler is dropped while one reachable via a non-event path stays. +unit test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): recover // tag in the go/bash annotation fallback The wasm path carries out.tag, but the go/bash fallback (and the wasm-error degradation path) only recovered pipeline + on, so a // tag gpu on a bash/go node — or a temporarily-unparseable ts/py/sql node — silently routed the local preview to the default worker while the deployed pipeline routes to the tag. Scan for // tag in fallbackParse too. +test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(pipeline): extract shared assetProducers helper The 'who writes this asset' write-edge derivation was copied verbatim in PipelineDevView and the pipeline route page — two copies that would drift. Extract assetProducers(graph, selection) into graphTraversal.ts and use it from both, keeping the dev view and route page in lockstep. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): only overwrite AGENTS.md/CLAUDE.md when it's the exact generated pointer Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): wire local-dev runs into the selected-node runs pane Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): exclude data_upload/webhook entrypoints from auto CLI runs Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(pipeline): --upload binds an object to a data_upload/webhook entry point Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(pipeline): add "Run + downstream" to the dev preview detail form Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): cut non-autorun triggers on all run paths; multi-binding --upload Address CI review: apply the data_upload/webhook/event barrier cut to the single-root and bounded (--from/--to) paths, not just whole-pipeline; accumulate repeatable --upload bindings per script (were overwritten); scope dev upload keys by script+param to avoid basename clobbering; drop <script> from help text. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): reseed dev run form when a local edit changes the script's args The read-only pane is keyed on script.path only, so in /pipeline_dev the selected node re-resolves on every WS bundle without remounting; PipelineScriptView cloned script.schema once, so adding/removing args left the run form on a stale schema (could run with missing inputs). Extract PipelineRunForm (owns the SchemaForm clone) and key it on the serialized schema: a real arg change reseeds the form, an unchanged re-resolve keeps in-progress input. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): don't cut a scheduled/manual root that also has a non-autorun trigger Address Codex P1: the barrier set subtracted only --upload-bound scripts, so a script with both `// on schedule` and `// on data_upload` resolved as the start yet was also a barrier — reachableCutting skipped it, giving an empty run plan. Subtract all valid starts (schedule/manual roots + bound handlers) from barriers: a legitimately-scheduled root runs on its schedule path even if it also carries a caller-input trigger; pure input-only roots stay cut. Adds a regression test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): deployed non-autorun enrichment, s3:// storage, --to cut accounting, tag regex Address CI review (Codex P1/P1/P2, Pi P2): - Deployed `pipeline run` recovers marker-only data_upload/webhook/email triggers from script bodies (like the `show` path) so input-only entrypoints are cut instead of auto-run empty on the deployed graph. - `--upload s3://<storage>/<key>` keeps the named storage (authority) instead of folding it into the key, matching the S3Object round-trip convention. - Bounded `--to` targets cut by a barrier are reported in droppedEnds (+warning), not reachableEnds. - fallbackParse `// tag` matches a single token (\S+), rejecting multi-word prose. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): header-only deployed marker scan, fail-closed enrichment, default-storage s3 keys Address CI review (Codex P2, cubic P1/P1/P2): - Deployed marker recovery scans the LEADING comment header only (shared recoverHeaderMarkers helper, reused by the show enrichment too) so a body comment `// on data_upload` can't inject a phantom trigger and over-cut. - Deployed run enrichment fails CLOSED: a script-body fetch error aborts the run instead of silently letting an input-only entrypoint run with empty args. - Revert `--upload s3://` to default-storage whole-path keys (matching pipeline `s3://` asset-URI semantics); named-storage authority-splitting broke nested default keys like `s3://raw/2026/events.csv`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): reject trailing content on fallback native markers; trim s3:/// key Address CI review (Codex P2, cubic P3): - fallbackParse now requires a native marker (`// on data_upload`) to stand alone; a line with trailing content (`// on data_upload f/foo`, `# on kafka topic`) is rejected, matching the canonical parser and keeping local/deployed parity. - s3UriKey trims a leading slash so the canonical empty-authority default form `s3:///key` doesn't leak a leading slash into the object key. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): persist dev WS token per-port so reconnect survives a CLI restart Address Codex P2: the /pipeline_dev auto-reconnect reuses the ws_token from the page URL, but `pipeline dev` minted a fresh random token each start, so a restart on the same port left the open page rejected by verifyClient forever. Persist the token per-port under the user-private config dir (0600) and reuse it on restart, so an already-open page reconnects — matching the reconnect behavior's intent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): scope persisted dev WS token by workspace+folder+port Address cubic P2: keying the persisted token by port alone let a stale browser tab from a previous folder's session on the same port reconnect and receive a different folder's source. Scope the token file by workspace+folder+port so a same-session restart still reconnects, but a different folder on the same port gets a distinct token that rejects stale cross-folder tabs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): caller args can't override skip-dispatch guard; hash the dev token key Address CI review (Codex P1, cubic P2): - makeLaunch / CLI run build args with `_wmill_skip_asset_dispatch` LAST (and drop any caller-supplied copy) so a run-form/`--upload` arg can't re-enable backend asset dispatch while the client orchestrates the cascade (double-run / running deployed subscribers from a local preview). Adds a cascadeRun guard test. - Dev WS token file key is a sha256 of NUL-delimited workspace+folder+port, so different folders (`a/b` vs `a_b`) can't collide onto the same token file. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(pipeline): canonical s3://storage/key --upload parsing; scope dev token by remote+root Address Codex P1/P1: - Restore canonical S3Object URI parsing for `--upload` s3 sources, matching the frontend's `parseS3Object` (`s3://<storage>/<key>`, empty authority ⇒ default, `s3:///key`/`s3:///nested/key` for the default store). `s3://secondary/k.csv` → `{ s3: "k.csv", storage: "secondary" }` so a named-storage object is read from the right store. (This is the canonical convention; the default-storage nested key is served by the `s3:///` form.) - Scope the persisted dev WS token by remote+workspace+root+folder+port (was workspace+folder+port), so two profiles on different remotes (or local checkouts) with the same workspace/folder/port don't share a token — a stale tab can't reconnect across a workspace/remote boundary.

You can find more information in Windmill Docs
Installation
Install the wmill CLI tool using npm install -g windmill-cli.
Update to the latest version using wmill upgrade.
Workspaces
To get started run wmill workspace add or use the instructions from the
workspace settings.
Running Flows & Scripts
Run a script or flow using wmill flow/script run u/username/path/to/script and
pass any inputs using --data + Inputs specified as a JSON string or a file
using @ <filename> or stdin using @-.
Curl-style syntax using -d @- for stdin or -d @<filename> is also supported.
Flow Steps and Logs will be streamed during execution automatically.

The CLI can push specifications to a windmill instance. See the examples/ folder for formats.
Switch to a different workspace
wmill workspace switch <workspace_name>
Sync a workspace
Pull
wmill sync pull
Push
wmill sync push
We recommend using the --yaml option to use yaml instead of json as the encoding format. Yaml will be made the default soon.
Pushing individual files
You can push individual resources using
wmill <type> push <file_name> \<remote_name\>. This does not require a special
folder layout or file name, as this is given at runtime.
Listing
All commands support listing by just not providing a subcommand, ie
wmill script will result in a list of scripts. Some allow additional options,
learn about this by specifying --help.
User Management
You can add & remove users via wmill user add/remove, and list them using
wmill user
Pulling
You can pull the entire workspace using wmill pull
Completion
The CLI comes with completions out of the box via wmill completions <shell>.
(Via cliffy)
Bash
To enable bash completions add the following line to your ~/.bashrc:
source <(wmill completions bash)
Fish
To enable fish completions add the following line to your
~/.config/fish/config.fish:
source (wmill completions fish | psub)
Zsh
To enable zsh completions add the following line to your ~/.zshrc:
source <(wmill completions zsh)
Development
AI Guidance Variants
wmill init can now materialize alternate AI guidance bundles without changing
the generated defaults in the repo, but this is exposed as internal env-var
overrides rather than public CLI flags.
Examples:
WMILL_INIT_AI_SKILLS_SOURCE=/path/to/custom/skills wmill init --use-default
WMILL_INIT_AI_SKILLS_SOURCE=/path/to/custom/skills WMILL_INIT_AI_AGENTS_SOURCE=/path/to/AGENTS.md wmill init --use-default
WMILL_INIT_AI_SKILLS_SOURCE=/path/to/custom/skills WMILL_INIT_AI_CLAUDE_SOURCE=/path/to/CLAUDE.md wmill init --use-default
This is the same guidance-writing path used by the benchmark CLI under
ai_evals/, so the benchmark harness and wmill init now generate the same
project guidance shape:
AGENTS.mdCLAUDE.md.agents/skills/*.claude/skills/*
