health-check

health-check is a command for Claude Code from 0xUXDesign/ai-codebase-boilerplate. It costs 8 tokens per session (252 once invoked), scanned A, original, MIT.

A periodic codebase audit that checks for unused code, duplicated code, circular dependencies, TODO comments, oversized files and functions, and source and test size.

In plain words
What is it for?
Use it to find dead exports, unused dependencies, repeated code, dependency cycles, unfinished work, and areas that may need refactoring.
Why use it?
It turns accumulated maintenance problems into a health scorecard instead of leaving them hidden in the repository.

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

health-check 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 9d 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.

What it actually says

Run a full codebase health audit:

  1. npx knip — dead exports, unused files, unused dependencies
  2. npx jscpd src/ --threshold 5 — code duplication report
  3. npx madge --circular --extensions ts,tsx src/ — circular dependencies
  4. Find all TODO/FIXME/HACK/DEBT comments: grep -rn "TODO\|FIXME\|HACK\|DEBT" src/
  5. Find files over 500 lines: find src/ -name "*.ts" -o -name "*.tsx" | xargs wc -l | awk '$1 > 500'
  6. Find functions over 50 lines (approximate): look for long function bodies
  7. Count total source LOC: find src/ -name "*.ts" -o -name "*.tsx" | xargs wc -l
  8. Count total test LOC: find . -name "*.test.ts" -o -name "*.test.tsx" | xargs wc -l

Present as a health scorecard with trends if previous data exists.

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.
