  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Weft Language is an agent skill from WeaveMindAI/weft. Read before writing or editing any .weft source: declarations, wiring, config literals, reserved keys, inline signatures and expressions, types, groups and the level rule, included files, loops, the pulse execution model, @file, @asset and @include, and every compiler error slug.

Its SKILL.md is about 13k 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.

Example prompts

  • “/weft-language”

Requirements

  • Python 3

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 (its code samples are weft).

    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 Language loads about 13k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 8,224 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~13k

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 8,224 words (~13,265 tokens).

“One way to say each thing, and the compiler refuses everything else. This page is the whole surface as of this template; when it disagrees with your memory, this page wins.”
