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.

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 | $0.00691 | $0.00691 |
| Opus 5 | $0.00345 | $0.00345 |
| Sonnet 5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
claude-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 5d 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.

Overview: Claude Agent Skills Stack
This repository implements a decentralized "Claude Agent Skills" architecture. Each skill is self-contained and provides tools, references, and validation scripts for agents.
Execution Environment
- Python Scripts: Use
uvfor dependency management whenever possible. Scripts should be executable viapython <script_path>. - Mandatory Requirements:
- All
SKILL.mdfiles MUST contain a YAML front-matter withname,description, andtools(as a YAML list). - POSIX compliance: All text files must end with a newline (
\n) and use LF line endings. - Example front-matter:
--- name: my-skill description: "Skill description" tools: - Read - Write ---
- All
Key Paths
skills/<skill-name>/SKILL.md: Main entry point for a skill.skills/<skill-name>/scripts/: Validation and analysis scripts.skills/<skill-name>/assets/: Templates and static resources.skills/<skill-name>/references/: Documentation and best practices.
Release & Versioning
Two decoupled version spaces — never align one to the other:
- Per-skill version → SemVer. Each skill carries its own
metadata.versioninSKILL.md(e.g.4.0.0), bumped major/minor/patch according to the change in that skill. Independent across skills. - Repo release tags → CalVer. Git tags use
vYYYY.MM.MICRO(e.g.v2026.05.0, thenv2026.05.1for a second release the same month,v2026.06.0the next month). A tag means "a publish happened" — it is not the version of any skill.
Tagging procedure:
- Next tag =
v$(date +%Y.%m).<micro>where<micro>is the highest existingvYEAR.MONTH.*tag + 1, or0if none this month. Legacy SemVer tags (v4.1.0and earlier) are ignored for this calculation. - Pre-checks:
main == origin/main, target commit pushed, andgit rev-parse -q --verify refs/tags/<tag>shows the tag is free. ThePublish Skillsworkflow (triggerv*) is destructive if a published tag is rewritten. - Annotated + GPG-signed tag, message
vYYYY.MM.MICRO - <summary>. - The
Publish Skillsworkflow needs no change:v*still matches, the tag is only used as the GitHub release name, and the.skillfilename strip targets the skill's SemVer in the filename, not the tag.
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.

claude-skills AGENTS.md is an instructions file published in the GitHub repository obeone/claude-skills (3 stars, last pushed today), licensed MIT. It adds 691 tokens to every session, about $0.0035 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.
