In plain words
What is it for?
They are for implementing, reviewing, or testing skillman features and its skills configuration commands.
Why use it?
They give an agent the project context, file structure, configuration rules, and testing expectations needed to work safely in the codebase.

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

skillman AGENTS.md 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 2d 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.

Project Overview

skillman is a CLI wrapper to manage project skills and lock them in skills.json. It provides a declarative way to install skills per project, similar to how package managers work with package.json.

Architecture

├── cli.ts              # CLI entry point with parseArgs
├── config.ts           # skills.json config management
├── skills.ts           # Skills CLI execution
└── utils/
    ├── colors.ts       # ANSI color codes for terminal output
    └── gitignore.ts    # .gitignore file management
test/index.test.ts      # Tests using vitest

Config (src/config.ts)

  • findSkillsConfig(cwd?) — Finds skills.json by traversing up from cwd
  • readSkillsConfig(options?) — Reads and validates skills.json (options: { cwd?, createIfNotExists? })
  • updateSkillsConfig(updater, options?) — Generic update with callback (options: { cwd?, createIfNotExists? }, defaults createIfNotExists: true)
  • addSkill(source, skills?, options?) — Adds a skill source (options: { cwd?, createIfNotExists? }, defaults createIfNotExists: true)
  • Auto-injects $schema field during validation if missing

Skills CLI (src/skills.ts)

  • findSkillsBinary(options?) — Finds local skills binary in node_modules/.bin (options: { cache? }, cached by default)
  • installSkills(options?) — Spawns skills add for each source with progress logging; options: { cwd?, agents?, global?, yes? }
  • installSkillSource(entry, options) — Installs a single skill source; options: { cwd?, agents?, global?, yes?, prefix? }

CLI Entry (src/cli.ts)

  • main(argv?) — CLI entry point using Node.js parseArgs
  • parseSource(input) — Parses source input into { source, skills }; supports:
    • Colon/comma format: owner/repo:skill1,skill2 or owner/repo:skill1:skill2
    • skills.sh URLs: https://skills.sh/owner/repo/skill-name

Utils (src/utils/)

colors.ts — ANSI escape codes for terminal styling:

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.
