Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00841 | $0.00841 |
| Opus 5 | $0.00420 | $0.00420 |
| Sonnet 5 | $0.00168 | $0.00168 |
| Haiku 4.5 | $0.00084 | $0.00084 |
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, includingcheck-skills.sh.skills/— the eight installable Agent Skills; each has aSKILL.mdand may have one-levelreferences/content.
Boundaries
Always:
- Run
mise run checkand require exit status 0 before every commit. - When changing a file under
skills/, keep the skill entrypoint atskills/*/SKILL.mdand runbash scripts/check-skills.shbefore 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 checkexits nonzero. - Add another
AGENTS.mdbelowskills/; the root file is the canonical agent instruction surface. - Change
skills/herdr-parallel-dev/scripts/verify-worktrees.shduring 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/, orscripts/check-skills.sh. - Before changing the install or update commands in
README.md, includingnpx skills add fang2hou/skills -gornpx skills update -g -y. - Before deleting or renaming any
skills/*/SKILL.mdor changing a published skill's frontmattername.
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.

skills AGENTS.md is an instructions file published in the GitHub repository fang2hou/skills (2 stars, last pushed 16d ago), licensed MIT. It adds 841 tokens to every session, about $0.0042 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
