* feat(sdk): allow overriding worker tag when running jobs Add an optional `tag` parameter to every job-running helper across the TypeScript, Python, PowerShell and Rust client SDKs. When set, it is forwarded as the `tag` query param on the `jobs/run/*` endpoints, which the backend already honors as a worker-tag override. The parameter is appended last and defaults to null/None everywhere, so existing positional and keyword callers are unaffected. Rust has no optional params, so its existing `run_script_async`/`run_script_sync` signatures are left untouched and new `*_with_tag` variants are added. Fixes WIN-2105 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(system_prompts): regenerate SDK docs for tag param Regenerate auto-generated system prompts so the TypeScript/Python SDK references (and the script skills that embed them) reflect the new optional `tag` parameter on the job-running helpers. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(powershell-sdk): preserve original RunScriptAsync/RunFlowAsync arities PowerShell class methods dispatch by exact argument count and have no default parameter values, so adding `$Tag` in place dropped the old 4-arg `RunScriptAsync` / 3-arg `RunFlowAsync` overloads — existing direct class calls would fail with "Cannot find an overload". Re-add the original arities as thin overloads that forward `$null` for `$Tag`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(system_prompts): generate prompts.d.ts to stop literal-content drift prompts.d.ts was a tracked declaration file with string-literal types baked in, but generate.py never regenerated it — only prompts.ts and the hand-written index.d.ts. So every prompt change (e.g. the new SDK `tag` param) left prompts.d.ts stale, and check-freshness didn't catch it because generate.py never wrote the file. Emit prompts.d.ts from generate.py as plain `export declare const X: string;` declarations. The contents now live only in prompts.ts, so the declaration file can't drift, and check-freshness covers it going forward.

Windmill CLI
A simple CLI allowing interactions with windmill from the command line.

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.
Pushing Resources, Scripts & More
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/*
Testing with a local windmill-yaml-validator
To test local changes to the validator before publishing, use npm link:
# In windmill-yaml-validator/
npm run build
npm link
# In cli/
npm link windmill-yaml-validator
