skill-repair

skill-repair is a skill for Claude Code, Codex from aaronjmars/aeon-agent. It costs 28 tokens per session (4,064 once invoked), scanned A, a copy of skill-repair, MIT.

A workflow for finding and repairing skills that are failing or performing worse than expected. It checks the problem, identifies its cause, applies a repair when possible, verifies the result, and records the outcome.

In plain words
What is it for?
It is for triaging tracked skills, fixing individual or shared causes, opening a pull request when a repair is applied, and reporting blocked, healthy, or unresolved cases.
Why use it?
It prevents isolated fixes when several skills share one underlying problem and distinguishes repairable issues from problems needing operator action. A dry-run option allows diagnosis without making changes.

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-repair scanned grade A 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 4d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`gh` and `git` handle auth internally, so the diagnostic reads carry no `$SECRET` on the command line. There is no network sandbox — `curl` works; use `gh api` for GitHub reads, and prefer **WebFetch** over `curl` for an

How it starts

The opening of the file, as written. The whole thing — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — Skill name to repair. If empty, runs systemic triage and picks the worst fixable target. ${var} modifiers: prefix dry-run: to diagnose only without writing a PR (e.g. dry-run:digest).

Today is ${today}. Your task is to diagnose and repair the worst-impact failing or degraded skill — preferring a single shared fix over N per-skill patches when failures cluster.

Phases

PREFLIGHT → TRIAGE → DIAGNOSE → REPAIR → VERIFY → LOG

Stop early at the appropriate exit code if any phase finds nothing actionable.

Exit taxonomy

Pick exactly one before notifying.

Code Meaning
REPAIR_OK_FIXED Per-skill fix applied, PR opened
REPAIR_OK_SYSTEMIC Shared root cause across N skills — single shared fix or shared issue filed
REPAIR_DIAGNOSED_NO_FIX Root cause known but requires operator action (e.g. missing secret, upstream API down). Issue updated, no PR
REPAIR_NO_TARGETS All tracked skills healthy and no open fixable issues
REPAIR_DRY_RUN var=dry-run:NAME — diagnostic only, no PR
REPAIR_BLOCKED Preflight failed (gh auth, missing files) or cooldown active

1. PREFLIGHT

Bail early with REPAIR_BLOCKED (and notify with the reason) if any of these fails:

  • gh auth status succeeds.
  • memory/cron-state.json exists and parses as JSON.
  • memory/issues/INDEX.md exists. If absent, bootstrap a minimal one (Open + Resolved tables, no rows).
  • memory/state/skill-repair-history.json exists. If absent, create {}.

Cooldown / idempotency (skip target with REPAIR_BLOCKED if any matches; don't loop on a fix that didn't take):

  • The chosen target appears in memory/state/skill-repair-history.json with last_repair_at within 24h. (Operator can override by deleting the entry.)
  • An open PR already exists matching fix/skill-repair-{name}-*gh pr list --state open --search "head:fix/skill-repair-{name}".
  • More than 3 skill-repair PRs already opened in the current UTC day — rate-limit our own PRs.

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.
