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 5.1 | $0.01039 | $0.01039 |
| Opus 5.5 | $0.00416 | $0.00416 |
| Sonnet 5.5 | $0.00208 | $0.00208 |
| Haiku 4.5 | $0.00104 | $0.00104 |
Grade C, and why
skills AGENTS.md scanned grade C with 1 finding 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 12d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Ask first: destructive ops (`rm -rf`, `git reset --hard`, force-push, branch delete) How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Agent Skills Catalog
Project
Skill definitions live in skills/<name>/. Installed copies under ~/.claude/skills/ and ~/.agents/skills/ are the runtime, not the source: edit only this repo.
Commands
- Validate one skill:
python3 ~/.claude/skills/skill-creator/scripts/quick_validate.py skills/<name> - Score one skill:
asm eval skills/<name>(--jsonfor per-category scores) - Package:
python3 ~/.claude/skills/skill-creator/scripts/package_skill.py skills/<name>(writesdist/) - Scaffold:
python3 ~/.claude/skills/skill-creator/scripts/init_skill.py <name> --path skills/ - Check every
evals/evals.json:python3 scripts/validate-evals.py - Trigger evals (tests the installed copy):
python3 scripts/run-skill-evals.py <name> --runs 3 - Local install:
bash install.sh. It's an interactive TUI that installs for real, takes no flags, and needs a TTY - There is no npm, pnpm, make, or pytest here. Don't invent test commands.
Constraints
- Never: edit installed skill copies (
~/.claude/skills/,~/.agents/skills/) from this repo - Never: hand-edit
dist/; regenerate it withpackage_skill.py - Never: commit
*-workspace/,.asm-improver/,.claude/scheduled_tasks.lock, secrets,.env, or**/credentials* - Never: add eval fixtures under
skills/; they go ineval-fixtures/<name>/(theskills/plugin folder is capped at 512 files) - Never: commit or push without an explicit user request (drafting the message is fine)
- Ask first: destructive ops (
rm -rf,git reset --hard, force-push, branch delete) - Ask first: a change that touches more than one skill
Conventions
- Every SKILL.md edit bumps
metadata.version(patch for wording, minor for a new capability, major for a restructure), and the skill's row in the rootREADME.mdshows the same version - Quote any frontmatter string containing
:#-<>|,&?! nameequals the skill's own directory name, suite children included (skills/<umbrella>/<child>/). Each suite SKILL.md validates and versions independently- SKILL.md stays under 500 lines and 3000 words; overflow goes to
references/ docs/README.mdopens with the AI-skip HTML comment (copy it from any existing skill)- A skill that mutates a git repo has a
## Repo Sync Before Edits (mandatory)section. A skill that invokes another skill has a## Dependency Preflight (mandatory)section - Small fix: make a minimal, targeted diff. Never rewrite a SKILL.md for a one-line change or refactor opportunistically
- New skill: run
init_skill.py, fill in SKILL.md, adddocs/README.md, validate, then add a CHANGELOG entry under## Unreleased - Before creating a skill, grep
skills/*/SKILL.mdfor one that already owns the behavior - Renaming a skill: change the frontmatter
name, the directory, and theREADME.mdcatalog references in the same commit - Commits use Conventional Commits (
feat:,fix:,chore:,docs:). Breaking changes go in the body, not the title
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.
