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

skills 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This repository is a collection of Agent Skills for coding agents that need reusable, task-focused workflows.

Commands

mise install
mise run format
mise run check

This repository has no test, build, or dev mise tasks. mise run check verifies Markdown formatting with oxfmt, runs the root skill-structure check, and runs the redacted Gitleaks scan; mise run format rewrites Markdown in place.

Engineering Standards

Follow the shared engineering guidelines in the AI Coding Guidelines portal. Read the portal recipe for the task before editing; repository documentation is the source of truth when it is more specific.

Project-specific overrides:

  • None. This repository follows the shared standards.

Layout

  • .github/ — GitHub Actions workflows and the pull request template.
  • scripts/ — repository validation scripts, including check-skills.sh.
  • skills/ — the eight installable Agent Skills; each has a SKILL.md and may have one-level references/ content.

Boundaries

Always:

  • Run mise run check and require exit status 0 before every commit.
  • When changing a file under skills/, keep the skill entrypoint at skills/*/SKILL.md and run bash scripts/check-skills.sh before opening a pull request.
  • When adding a relative link in a root document, point it to an existing path in this repository and recheck the link before committing.

Never:

  • Add package.json, pnpm-lock.yaml, tsconfig.json, or JavaScript/TypeScript source files; this repository validates Markdown and Bash instead.
  • Commit a change when mise run check exits nonzero.
  • Add another AGENTS.md below skills/; the root file is the canonical agent instruction surface.
  • Change skills/herdr-parallel-dev/scripts/verify-worktrees.sh during a skill-content change unless the request names that path.

Ask first:

  • Before adding a top-level directory or changing mise.toml, .oxfmtrc.json, .pre-commit-config.yaml, .gitattributes, .github/workflows/, or scripts/check-skills.sh.
  • Before changing the install or update commands in README.md, including npx skills add fang2hou/skills -g or npx skills update -g -y.
  • Before deleting or renaming any skills/*/SKILL.md or changing a published skill's frontmatter name.

Changes

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.
