A data table backed by the instance database resolved to exactly one Postgres connection, `custom_instance_user`, for everyone who could reach it at all. There was no way to say this job reads, that one writes, this one never sees the salaries table. A data table role is now a real Postgres login on the cluster, defined once for the instance by a superadmin and named exactly as they named it. A script that declares `-- role analytics` connects as `analytics`, and Postgres decides what it may touch — grants are ordinary SQL. Windmill answers only "may this caller ask for this role", from the tenant lists on the data table entry: `u/alice`, `g/analysts`, `f/finance` or `*`. A data table with no `permissions` block behaves exactly as before. Everything that opens a connection on someone's behalf goes through one chokepoint, `get_datatable_resource_from_db`, which takes the identity explicitly and fails closed when there is none. The role logs in as itself — never `SET ROLE`, which a script could `RESET ROLE` its way out of. A fork's data table entry becomes a pointer at the workspace that governs it rather than a copy of it. The settings clone used to hand a fork a byte-identical entry naming the parent's database, which a fork admin could edit to grant themselves `admin` there; a pointer has nothing local to edit, and its tenants are evaluated as a member of the governing workspace, by email. `permissions` is stripped from the workspace export and ignored on import: tenants name principals of one workspace, and a settings push is not where an access decision should be made. Operations that see the whole database whatever the roles grant stay with the governing workspace's admins: editing the roles, a migration that declares none, and opening a replication stream for a Postgres trigger or capture.

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-pluginrepo 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:
- Parse TypeScript and Python SDK files to extract function signatures
- Parse the OpenFlow YAML schema
- Parse the CLI commands
- Assemble complete prompts from markdown files
- Generate TypeScript exports in
auto-generated/ - Optionally refresh plugin-ready standalone
SKILL.mdfiles 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.pyto update exports
