Ruben Fiszel f0301b1605 feat(flows): preserve step/subflow worker tags under a custom-tagged flow (#9375)
* feat(flows): preserve step/subflow worker tags under a custom-tagged flow

A flow running on a custom worker tag force-propagates that tag to every
descendant step, script and nested sub-flow, overriding their own declared
tags. This made it impossible to route a specific step or sub-flow to a
different worker group. The new opt-in FlowValue.preserve_step_tags lets a
step that declares its own non-empty tag run on it; untagged steps still
inherit the flow tag. Defaults off to preserve existing behavior.

* chore: regenerate system prompts for preserve_step_tags

* feat(flows): nest preserve_step_tags toggle under flow worker tag setting

The toggle only affects routing when the flow has a custom worker tag, so
show it as a sub-setting of the Worker Group tag picker, visible only once a
tag is set, instead of as a standalone option.

* fix(flows): allow step worker tag picker when preserve_step_tags is enabled

When a flow defines a worker tag, the per-step tag picker was replaced by a
read-only "Flow's WG" label. With preserve_step_tags enabled the step's own
tag is honored, so the picker must remain editable in that case.

* fix(flows): propagate preserve_step_tags to branch and loop bodies

payload_from_modules built the synthetic RawFlow for branch/loop bodies with
a default FlowValue, dropping preserve_step_tags. Tagged steps inside a
branch or loop therefore still inherited the parent flow tag even with the
flag enabled. Thread the flag through to the synthetic FlowValue so the
behavior is consistent for nested containers.

* fix(flows): clear preserve_step_tags when flow worker tag is removed

Avoids the flag lingering as invisible state after the flow tag (and its
toggle) are removed.

* fix(flows): repair preserve_step_tags propagation to branch/loop bodies

The previous commit added flow.preserve_step_tags at the payload_from_modules
call sites but the parameter and FlowValue field were not actually threaded
through (a failed edit left the function unchanged), so the crate did not
compile. This completes the change: payload_from_modules takes preserve_step_tags
and sets it on the synthetic FlowValue for branch/loop bodies.

* fix(flows): complete preserve_step_tags propagation to branch/loop bodies

Previous two commits left windmill-worker uncompilable: payload_from_modules
received flow.preserve_step_tags at its call sites but the parameter and the
synthetic FlowValue field were not actually added. This adds the parameter,
sets preserve_step_tags on the synthetic FlowValue, and threads
flow.preserve_step_tags through all five call sites.

* fix(flows): clear preserve_step_tags whenever the flow worker tag is removed

The flag was only reset when the Worker Group toggle was switched off, not
when the tag was cleared directly in the picker (or via the YAML editor),
leaving preserve_step_tags=true as invisible state with the advanced badge
still reporting it active. Move the cleanup into the reactive block that
already tracks the flow tag so every clear path is covered.

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.

CLI input example

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.md
  • CLAUDE.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
