manage-codex-skills

manage-codex-skills is a skill for Codex from WildPigKing/codex-project-skill-manager. It costs 58 tokens per session (370 once invoked), scanned A, original, MIT.

A library manager for Codex skills, which are reusable instructions for handling specific tasks. It keeps a registry and generated menu so skills can be found, checked, classified, or moved with approval.

In plain words
What is it for?
Use it to route a task to up to three relevant skills, inspect the skill library, propose categories, validate registrations, rebuild the skills menu, or apply approved moves and classifications.
Why use it?
It reduces the work of searching a large skill collection and finding missing, duplicated, or incorrectly registered entries. It also keeps changes under user control.

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

manage-codex-skills 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/rebuild_skills_menu.py, scripts/validate_skills_menu.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.

What it actually says

Manage Codex Skills

Treat skills-menu.json as the registry source and SKILLS_MENU.md as generated output.

Route a task

  1. Scan every menu row by skill name, trigger, and output.
  2. For each distinct task or subrequest, shortlist at most three relevant skills.
  3. Read only the complete SKILL.md files for the shortlist.
  4. State the order when multiple skills are complementary.
  5. Continue without a skill when there is no good match.
  6. Do not bulk-load all skills or route by category name alone.

Organize a library

  1. Inventory skill names, descriptions, paths, categories, sources, and statuses read-only.
  2. Detect missing registrations, duplicate names, invalid frontmatter, and path conflicts.
  3. Propose a category for each unclassified skill with a short reason and confidence. This proposal is read-only and is not a persisted classification.
  4. Show exact directory creations and optional relocations.
  5. Let the user approve all, some, or none. An unmanaged skill stays in place and remains usable.
  6. Apply only approved changes. Recording a category, rebuilding a user menu, or moving a skill is a write. Then validate the resulting menu.

Run scripts/rebuild_skills_menu.py to generate the menu. Run scripts/validate_skills_menu.py before reporting completion.

Passing format validation does not prove a skill is effective. Use draft before representative testing, tested after one successful realistic use, and stable only after repeated successful use.

Files

What ships with it

3 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.
