What it does

Weft Check is an agent skill from WeaveMindAI/weft. COMMAND, not reference: Validate and build the weft program, fix diagnostics until clean. Run this when the user asks for this step by name. The weft- reference skills beside it are things you read; this is a procedure you carry out.

Its SKILL.md is about 310 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: A programming language for AI orchestrations.

When your agent uses it

  • Asks for this step by name

Example prompts

  • “/weft-check”

Workflow steps

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

  1. Read the weft-language skill if you have not this session, and the metadata.json of any node type you are about to edit. Then: weft…
  2. Parse the diagnostics. Errors are line:column message with a stable slug; the message names the fix. Fix every Error, then re-validate…
  3. Then weft build. If it fails, read the error, fix, rebuild.
  4. Report, in plain words: what was wrong, what you changed, and the current state (clean validate, clean build). No summary of the diff.

What it can do on your machine

Read from SKILL.md and the folder at commit 6e28f31. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Weft Check loads about 305 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~305

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 163 words (~305 tokens).

“Run the compiler over this project and fix what it names, without running anything.”
