Diego ImbertandClaude Opus 5 715d8a0e6d fix(datatables): give the role catalog its own row, out of reach of the config machinery
Putting it inside `custom_instance_pg_databases` was the wrong call, and it cost two ways.
The catalog serializes a generated Postgres password per role, and that row is the
operator-facing instance config, so the passwords reached `get_instance_config` and its YAML
editor — a live cluster credential in a response body, a UI field and any log of either.
Worse in the other direction: `to_settings_map` strips the catalog, so a full-row upsert of
that key writes the row back without it and the catalog is gone, while the cluster keeps every
login it described.

`custom_instance_replication_pwd` is the precedent and says exactly why — a generated secret,
written only by the server, never operator-authored, hidden so the config machinery cannot
read, rewrite or drop it. The catalog is the same thing, so it now has the same shape:
`datatable_roles`, in `HIDDEN_SETTINGS`, `PROTECTED_SETTINGS` and the agent-worker denylist.
No redaction to keep in step with three code paths, and no way for a neighbouring write to
take it out.

Two races on the same shared documents. `edit_datatable_config` read the stored data tables
outside its transaction and then wrote the whole `datatable` document, so a permissions save
committing in between was silently rolled back; it now reads under `FOR UPDATE`. And
`set_datatable_permissions` validated role ids against the catalog before opening its
transaction, so a deletion in between let it write a deleted role back — including as the
default, which every later job then fails on; it now holds the catalog lock and the settings
row across validation and write.

Completes the authorization contracts the previous commit claimed but did not finish:
`read_datatable_entry` (which it named and missed), `resolve_governing_datatable`, whose whole
job is to answer for a workspace the caller may not belong to, and
`converge_connect_grants_with`, which had not inherited its wrapper's.

Also the generic Python SDK reference: `_format_py_params` learned the bare `*` last time, but
`extract_py_functions` is a second formatter and still rendered `datatable(name, role)`, so
code written from that page passed a keyword-only argument positionally.

System Prompts

This directory contains the single source of truth for AI system prompts used by both the frontend copilot and CLI guidance.

Usage

Regenerating Prompts

When SDK methods or the OpenFlow schema change, run:

python system_prompts/generate.py

To also refresh the standalone skills in a Claude plugin checkout:

python system_prompts/generate.py --plugin-dir ~/windmill-claude-plugin

--plugin-dir accepts:

  • the windmill-claude-plugin repo root
  • a plugin root such as plugins/windmill
  • a direct skills/ directory

To regenerate the public docs repo (consumed by context7):

python system_prompts/generate.py --context7-dir ~/windmill-cli-docs

--context7-dir writes a fully-rendered snapshot (AGENTS.md, cli-commands.md, skills/<name>/SKILL.md, README.md, manifest.json with the Windmill version) with all template placeholders resolved — suitable for ingestion by docs aggregators. In CI this runs from .github/workflows/publish-cli-docs.yml on every release tag. The generator refuses to wipe the target directory unless it's empty or has a context7 marker (context7.json, manifest.json, or a windmill-cli-docs git remote), so a typo can't delete unrelated files.

This will:

  1. Parse TypeScript and Python SDK files to extract function signatures
  2. Parse the OpenFlow YAML schema
  3. Parse the CLI commands
  4. Assemble complete prompts from markdown files
  5. Generate TypeScript exports in auto-generated/
  6. Optionally refresh plugin-ready standalone SKILL.md files in the target directory

Scope

These system prompts contain ONLY:

  • How to write Windmill scripts (language syntax, conventions, SDK usage)
  • How to structure Windmill flows (OpenFlow schema, module types, data flow)
  • Resource type handling, S3 operations

They DO NOT contain:

  • Tool usage instructions (edit_code, set_flow_json, etc.)
  • IDE/editor specific commands
  • Testing tool invocations

Tool instructions are added separately by the frontend and CLI.

CLI-only workflow instructions live in base/flow-cli.md and are included in the generated write-flow skill for wmill init. They are intentionally excluded from the frontend flow chat prompt.

Integration

Frontend

Uses Vite path alias $system_prompts pointing to auto-generated/:

import { FLOW_GUIDANCE } from "$system_prompts/flow";
import { getLangContext } from "$system_prompts/languages";

CLI

Generates /cli/src/guidance/skills.gen.ts with embedded skill content for wmill init.

Editing Guidelines

  • Edit markdown files in base/, languages/
  • Never edit files in auto-generated/ directly
  • After editing, run generate.py to update exports
