What it does

Refine is an agent skill from windmill-labs/windmill. End-of-session reflection. Reviews friction encountered during the session and proposes updates to docs/ to capture lessons learned.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Open-source developer platform to power your entire infra and turn scripts into webhooks, workflows and UIs. Fastest workflow engine (13x vs Airflow). Open-source alternative to…

Example prompts

  • “/refine”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify friction: Review what happened in this session
  2. Read current docs: Read the docs that were relevant to this session
  3. Propose updates: For each piece of friction, decide if it warrants a doc update
  4. Apply updates: Edit the relevant docs/ files. Keep changes minimal and specific — add only what would have saved time this session.
  5. Report: Summarize what was added/changed and why.

What it can do on your machine

Read from SKILL.md and the folder at commit f40eea2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Refine loads about 420 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 216 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~420

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 216 words (~420 tokens).

“Reflect on the current session and update documentation with lessons learned.”
