In plain words
What is it for?
Use it when authoring, bundling, documenting, or distributing a skill folder.
Why use it?
It removes uncertainty about how a skill should be structured and prepared for handoff.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is tar -xzf my-skill.tar.gz -C ./skills/.

Good fit Use it when authoring, bundling, documenting, or distributing a skill folder.

About the project

Brigade is an ecosystem for running crews of AI agents as a personal intelligence system, with local handling of credentials and support for exposing agent crews to the internet for testing. It is for people who want to organize and operate multiple AI agents using their own API keys or existing Claude, ChatGPT, Copilot, Claude Code, or Codex access. The catalogue skills provide workflows for using Brigade and its agent ecosystem.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

share-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Sharing Skills

This skill explains how skills are structured and how to package one for sharing. It is a companion to skill authoring: where skill-creator helps you write a skill, this covers laying it out correctly and bundling it to hand off.

Where skills live

Each skill is a folder under the skills/ directory. The folder name is the skill's identity and must match the name field in its frontmatter (lowercase). At minimum a skill folder contains a SKILL.md; it may also include supporting files (scripts, reference docs, assets) the skill refers to.

skills/
  my-skill/
    SKILL.md
    reference.md        # optional supporting docs
    scripts/run.sh      # optional helper scripts

SKILL.md format

A SKILL.md is a Markdown file with a YAML frontmatter block followed by the skill body.

---
name: my-skill          # must equal the folder name, lowercase
description: Use when ...  # the "use when" trigger guidance, product-free
# optional eligibility keys (omit any that don't apply):
os: [darwin, linux]       # OS restriction
requires-bins: [foo]      # binaries that MUST be present
requires-any-bins: [a, b] # at least one of these binaries
requires-env: [MY_TOKEN]  # required environment variables
---

Body guidelines:

  • Open with a short overview of what the skill does and when to reach for it.
  • Keep instructions truthful: only describe actions the runtime can actually perform.
  • Reference any supporting files by relative path within the folder.
  • Keep it lean — the description and metadata are what get surfaced; the body is read on demand.

Versioning a shared skill

When you intend to share a skill, keep a changelog note and a version in mind so recipients can tell revisions apart. A simple convention is a ## Changelog section at the bottom of SKILL.md or a sibling CHANGELOG.md.

Packaging a folder to share

To share a skill, bundle its entire folder (so supporting files travel with it) and hand it off as an archive.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
