skill-health

skill-health is a skill for Claude Code, Codex from aaronjmars/aeon-agent. It costs 0 tokens per session (8,220 once invoked), scanned A, a copy of skill-health, MIT.

A maintenance and reporting skill for checking the health of other skills and reviewing their recent run data. It can also work with recorded issues and fleet-wide metrics.

In plain words
What is it for?
Use it for per-skill health checks, issue tracking, and analytics over recent skill runs.
Why use it?
It makes failures, unresolved issues, unusual results, and changes in skill performance easier to find.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/skill-runs --json --hours $WINDOW_HOURS > output/.chains/skill-analytics-runs.json 2>/dev/null.

Good fit Use it for per-skill health checks, issue tracking, and analytics over recent skill runs.

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-health 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 7d 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.

This skill fetches no URLs directly — all data is local or via `gh` / `./scripts/skill-runs` (which uses `gh api`, so auth comes from `GITHUB_TOKEN` with no secret ever on the command line). No `curl` fallback needed.
Origin

This is a copy

98% identical to skill-health — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

${var} — View selector.

  • empty → health check across all scheduled skills (default).
  • a skill slug (e.g. token-movers) → health check for that one skill.
  • analytics or metrics (optionally analytics:HOURS, e.g. metrics:72) → fleet metrics view over the last HOURS (default 168 = 7d, cap 720).
  • a bare integer (e.g. 168) → metrics view with that window in hours (legacy shorthand).

Overview

This skill provides two views over the same GitHub-Actions skill-run data. They share a preamble but branch into distinct logic:

  • health (default): per-skill classification, issue filing/resolution against memory/issues/, and a state-change-gated notification. This is the load-bearing self-healing view — its issue contract, memory/skill-health/ scoring, and ### skill-health log shape are depended on by the health loop and other skills. Do not weaken it.
  • analytics (metrics): a fleet-wide ranked view — top runners, failure rates, exit-taxonomy distribution, silent-scheduled detection, and anomaly flags — with a significance-gated notification plus an article and a dashboard JSON spec. heartbeat gives binary ok/not-ok per run and the health view audits skills one degradation-band at a time; the analytics view is the only place the operator sees the entire fleet ranked side-by-side.

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.
