okhp3-skill-cataloger

okhp3-skill-cataloger is a skill for Codex from OKHP3/skillz. It costs 103 tokens per session (1,908 once invoked), scanned A, original, MIT.

A tool for cataloguing Agent Skills stored in a repository. It inventories skill folders, checks their names and descriptions, and creates a README catalogue plus metadata.

In plain words
What is it for?
Use it to list, validate, check versions, or refresh the catalogue of skills under .agents/skills/.
Why use it?
It removes the manual work of keeping a skill index accurate and can show validation problems instead of hiding them.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node artifacts/forge/scripts/build-catalog.js.

Good fit Use it to list, validate, check versions, or refresh the catalogue of skills under .agents/skills/.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

okhp3-skill-cataloger 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 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/gen-skills-readme.py, tests/test_write_family_md.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Intent: Turn a repository’s SKILL.md files into a reproducible inventory without editing skill content or hiding validation failures.

Scope boundary

In scope Out of scope
Discovering skills and reading their frontmatter Rewriting, installing, deleting, or upgrading skills
Validating names, descriptions, and duplicate names Editing README prose outside generated markers
Generating marked README catalogs and .catalog-meta.json Claiming a benchmark, security audit, or live marketplace result
Generating full-index FAMILY.md inventory sections Running --full casually in an application repository

Mode contract

Run from the repository root. The bundled script is the fallback; prefer a project-level scripts/gen-skills-readme.py only when it is the same or newer implementation and you have inspected it.

Operation Command Scans Generated outputs
Catalog (default) python3 ${SCRIPT} --skills-dir .agents/skills Direct child skill folders .agents/skills/README.md between catalog markers and .agents/skills/.catalog-meta.json
Catalog, flat add --mode project .agents/skills/<skill>/SKILL.md One flat table: Skill, Description, Version, Category
Catalog, categorized add --mode library .agents/skills/<category>/<skill>/SKILL.md Category sections with skill counts
Full index python3 ${SCRIPT} --full Root <family>/<skill>/SKILL.md folders; skips .agents/, skills/ export mirrors, and tool directories Root README.md, active-family FAMILY.md, root .catalog-meta.json

--full is a distinct distribution-surface operation and always uses library grouping. It does not catalog .agents/skills/ or the root skills/ publication mirror. In full mode, --output changes the root catalog path; family files and root metadata remain part of the run.

Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
