skill-manager

skill-manager is a skill for Claude Code, Codex from Stepkar2004/init-configurator. It costs 137 tokens per session (1,176 once invoked), scanned A, original, MIT.

A skill-lifecycle management tool that reviews the collection of skills used by a coding agent and records lessons learned.

In plain words
What is it for?
Use it to review skills, add or split them safely, merge related skills, process lessons from missed work, and check whether the overall skill set still has useful coverage.
Why use it?
It helps prevent too many overlapping skills, outdated instructions, missing knowledge, and undocumented decisions.

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

skill-manager 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

skill-manager — the one skill that is aware of all the others

Individual lessons enter through the evolve procedure, one reviewed diff at a time. Somebody still has to see the whole genome: whether the pieces are at the right altitude, whether gaps and corpses are accumulating. That somebody is this skill, and the periodic pass runs with FRESH context — the writer of a skill never grades it.

Nested-skill architecture (policy, decided 2026-07-11)

  • Few top-level skills, lazy references inside. A skill's body is the always-loaded front door; variants and less-common procedures live in references/ files loaded only when their trigger row matches. Do not rely on separate sibling skills auto-triggering for sub-procedures.
  • Hard cap: 10 top-level skills; prefer 5-7. At the cap, adding a skill requires first consolidating two related ones (merge into core + references). Current top-level set (4): workflow, skill-manager, socials, bootstrap.
  • Portability. Embed the external knowledge the genome needs (e.g. authoring standards in references/authoring.md) so any coding agent operating this repo has it — never depend on a specific tool's plugin being installed.

The structural rules (load-bearing, not style)

  • Skills exist per task-shape, never per incident. A recurring bug becomes one appended procedure in an existing skill, not a new skill.
  • Variants of one shape are references/ inside one skill (bootstrap + references/python.md; workflow + references/scale.md), never sibling skills.
  • Altitude smells: the same diff recurs after a fix → it was patched too low; one edit forces rewriting siblings → it lives too high.
  • Bodies stay under ~500 lines (alarm at 150). A bloated skill fails silently — it stops being read carefully. Push volatile detail down into references; push behavioral rules up into CLAUDE.md only when truly session-wide.
  • No version numbers in skill bodies. Decision procedures survive years; pins go stale invisibly. Dated observations are allowed in references, marked with their date.
  • Authoring standards (descriptions as triggers, progressive disclosure, eval method): references/authoring.md.

What ships with it

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.
