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 | $0.00008 | $0.00252 |
| Opus 5 | $0.00004 | $0.00126 |
| Sonnet 5 | $0.00002 | $0.00050 |
| Haiku 4.5 | $0.00001 | $0.00025 |
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:
npx knip— dead exports, unused files, unused dependenciesnpx jscpd src/ --threshold 5— code duplication reportnpx madge --circular --extensions ts,tsx src/— circular dependencies- Find all TODO/FIXME/HACK/DEBT comments:
grep -rn "TODO\|FIXME\|HACK\|DEBT" src/ - Find files over 500 lines:
find src/ -name "*.ts" -o -name "*.tsx" | xargs wc -l | awk '$1 > 500' - Find functions over 50 lines (approximate): look for long function bodies
- Count total source LOC:
find src/ -name "*.ts" -o -name "*.tsx" | xargs wc -l - 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.

health-check is a command published in the GitHub repository 0xUXDesign/ai-codebase-boilerplate (11 stars, last pushed 5mo ago), licensed MIT. It adds 8 tokens to every session and 252 once invoked, about $0.0000 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 2026-08-30.
