mushi-health

mushi-health is a skill for Claude Code from kensaurus/cursor-kenji. It costs 72 tokens per session (1,652 once invoked), scanned A, original, MIT.

A health-check procedure for the parts of a Mushi Mushi software pipeline, including credentials, APIs, deployed functions, keys, logs, and scheduled checks.

In plain words
What is it for?
Use it after setup or deployment, or when the Mushi pipeline is not responding, to check each part in order.
Why use it?
It helps identify the first failing component instead of treating later symptoms as separate problems.

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

mushi-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 8d 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.

Mushi Health Check

Degree of freedom: MIXED. First-red diagnosis [HIGH freedom]; Steps 1–6 in order [LOW freedom — run exactly].

How to reason

  1. Observedoctor, deploy check, keys, logs, cron — in that order
  2. Interpret — first red is root vs downstream symptom
  3. Classify — creds / functions-down / keys / logs / cron-missing
  4. Severity — paused project or invalid API key outranks a quiet QA cron on a new project

Worked example

Observe: mushi doctor green; mushi deploy checkqa-story-runner; qa_story_runs empty for 2h. Interpret: first red is the runner; empty cron is downstream. Classify: function-down — check get_logs for qa-story-runner; do not add keys yet. Verify: stop at Step 2; fix the runner; continue remaining steps only after it is green.

Self-critique before reporting

  • In order — did not skip ahead of the first ❌
  • Evidence — each row cites command output or a query, not memory
  • Stopped to fix — first red was remediated before later steps
  • Right owner — e2e loop proof → mushi-integration; targeted diagnosis → diagnose_setup

Run these checks in order. Stop and fix at the first ❌ before continuing.

Component map

# Component How to check
1 CLI credentials mushi doctor
2 API + edge functions mushi deploy check
3 Project overview mushi status
4 BYOK key pool mushi keys list or MCP list_byok_keys
5 Supabase logs Supabase MCP get_logs
6 QA cron running DB query on qa_story_runs

Step 1 — CLI credentials [LOW freedom — run exactly]

mushi doctor

Expected output — all lines green:

✓  ~/.mushirc found
✓  MUSHI_API_KEY valid (mushi_...)
✓  MUSHI_API_ENDPOINT reachable (200 OK)
✓  MUSHI_PROJECT_ID matches a live project
✓  Feature flags fetched

Fix if red: Re-run mushi login --api-key mushi_... --endpoint https://<ref>.supabase.co/functions/v1/api --project-id <pid>.

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.
