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 | $0.00013 | $0.00320 |
| Opus 5 | $0.00006 | $0.00160 |
| Sonnet 5 | $0.00003 | $0.00064 |
| Haiku 4.5 | $0.00001 | $0.00032 |
Grade A, and why
check-coverage 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 2d 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
Check Coverage
Analyze test coverage and identify gaps.
Workflow
1. Run Coverage (if available)
BASHUNIT_COVERAGE=true ./bashunit tests/
2. Map Functions to Tests
For each file in src/:
# List all public functions
grep "^function bashunit::" src/module.sh
# Find tests referencing each function
grep -r "function_name" tests/
3. Categorize Coverage
- Well tested — multiple tests, edge cases covered
- Partially tested — basic test exists, missing edge cases
- Not tested — no tests found
4. Identify Critical Gaps
Priority 1: Public API functions (export -f) with no tests
Priority 2: Error handling paths (return 1, exit 1) not tested
Priority 3: Complex conditionals without branch coverage
5. Generate Report
Output a markdown report with:
- Summary (total functions, tested count, estimated %)
- Coverage by module
- Critical gaps with file:line references
- Recommended tests to add (specific test function names)
Coverage Goals
- 90%+ for public functions
- All user-facing CLI commands tested
- All error paths tested
- Internal helpers: optional (if trivial)
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.

check-coverage is a skill published in the GitHub repository TypedDevs/bashunit (424 stars, last pushed 2d ago), licensed MIT. It adds 13 tokens to every session and 320 once invoked, about $0.0001 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.
