Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00061 | $0.00687 |
| Opus 5 | $0.00030 | $0.00344 |
| Sonnet 5 | $0.00012 | $0.00137 |
| Haiku 4.5 | $0.00006 | $0.00069 |
Grade A, and why
nyann:doctor 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 5d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin root: This is a Claude Code plugin, NOT a CLI tool. Do NOT
search via which, npm list, pip list, or brew list. This file

/nyann:doctor
Wraps bin/doctor.sh --target <cwd> --profile <name>.
Output is a three-section drift report plus DOCUMENTATION and GITHUB PROTECTION blocks:
MISSING: files the profile expects but the repo lacks
MISCONFIGURED: files present but content short of expectations
NON-COMPLIANT HISTORY: last N commit subjects that don't match Conventional
Commits (informational only — no rewrite offered)
DOCUMENTATION:
✓/⚠/✗ CLAUDE.md size against budget
✓/✗ internal link resolution
⚠ MCP links needing connector verification (skill-layer)
✓/⚠ orphan detector on docs/ + memory/
GITHUB PROTECTION: (when gh is reachable; soft-skips otherwise)
✗ branches/<name>: required_reviews, required_checks, …
✗ tags: pattern_present, blocks_force_push, …
✗ codeowners: file-missing-but-required, file-present-but-gate-off
✗ security: dependabot_alerts, secret_scanning, …
Exit codes:
| Code | Meaning |
|---|---|
| 0 | clean — no drift |
| 4 | warnings only (misconfigured, non-compliant history, orphans, CLAUDE.md warn/absent, soft protection drift) |
| 5 | critical (missing hygiene files, broken internal links, CLAUDE.md hard-cap error, missing branch/tag protection on a strategy-declared branch) |
When to invoke
- "is this project healthy?" / "check hygiene" / "audit docs" → run this.
- User asks to fix drift → this finishes, then dispatch to
/nyann:retrofitfor remediation. doctor never fixes.

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.

nyann:doctor is a command published in the GitHub repository thettwe/nyann (6 stars, last pushed 6d ago), licensed MIT. It adds 61 tokens to every session and 687 once invoked, about $0.0003 per session on Opus 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.
