A periodic report that checks whether a code repository has the files and guidance needed for AI-assisted development, and reviews feedback from recent merged pull requests.

Use it to assess repository readiness, mine recent pull-request feedback, prepare for releases, or run a weekly or monthly check.

It shows missing preparation and recurring review comments in one place, so improvement work is easier to prioritize.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Anti-Refusal · line 62
Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.01054
Opus 5.5	$0.00014	$0.00422
Sonnet 5.5	$0.00007	$0.00211
Haiku 4.5	$0.00003	$0.00105

Measured 16d ago against content hash 0d5b94504de9, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

repo-health 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 16d 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.

Repo health

Overview

One report from three scripts — repo-health-score.sh (nine assets, pass/partial/fail/na plus action_needed; no medal or aggregate; assets 5–6 read na outside the MTK checkout; rubric in .claude/references/repo-health-assets.md), audit-drift-check.sh, and pr-review-mine.sh (imperative reviewer phrases recurring across ≥2 merged PRs, tagged [MINED:feedback], suggest-only; heuristics and denylist in .claude/references/pr-mining-patterns.md). Writes .claude/repo-health-latest.md (always) and .claude/repo-health-latest.json (with --json); both are gitignored.

When To Use

"Is this repo AI-ready?", "repo health", "what should we improve?", "mine our PRs", "what do reviewers keep asking for?"
Periodically, before a major release, or after /mtk-setup --audit.

When NOT To Use

MTK usage numbers → mtk-doctor --usage.
Inside the build loop, or on a repo with fewer than 3 merged PRs (mining has no signal; run with --no-mining).

Workflow

Flags. --prs N (1..50, default 10), --json, --no-mining.
Checklist. bash scripts/repo-health-score.sh (add --json for the JSON file). The nine assets are canonical; never add, drop or re-grade one at runtime — a change goes through the reference and the script.

Audit drift (best-effort, never blocks):

CONST_DOC=AGENTS.md; [ -f "$CONST_DOC" ] || CONST_DOC=CLAUDE.md
for doc in "$CONST_DOC" .claude/references/architecture-principles.md .claude/references/conventions.md; do
  [ -f "$doc" ] || continue
  bash scripts/audit-drift-check.sh "$doc" || true   # exit 1 = drift
done

Drift annotates asset 2 as 🟨 audit drift: N citations; it never changes the status. Unstamped docs are skipped silently.

Mining (unless --no-mining): bash scripts/pr-review-mine.sh --prs <N>. Fail-soft: without an authenticated gh it prints Skipped: <reason> and exits 0 — report that line, never phrases from memory. A phrase needs ≥2 distinct PRs; one reviewer repeating it in one PR is not a team norm. Boilerplate that slips through ("great work") goes on the ## Denylist of pr-mining-patterns.md, then re-run; the denylist is never bypassed for one run.

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.

repo-health is a skill published in the GitHub repository moberghr/mtk-agent-toolkit (9 stars, last pushed 8d ago), licensed MIT. It adds 34 tokens to every session and 1,054 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
