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 | $0.00000 | $0.00182 |
| Opus 5.5 | $0.00000 | $0.00073 |
| Sonnet 5.5 | $0.00000 | $0.00036 |
| Haiku 4.5 | $0.00000 | $0.00018 |
Grade A, and why
test-coverage-analyzer 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 2mo 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
Complete Test Coverage Analysis
Analyze test coverage and quality across the entire repository.
This command provides complete testing analysis by:
- Identifying all test files and test patterns
- Mapping test coverage to source code
- Finding untested critical paths
- Analyzing test quality and patterns
- Generating testing improvement recommendations
Follow these steps:
- Use nodes-semantic-search to find all test-related code (test, spec, mock, fixture, jest, mocha)
- Get all test implementations with get-code
- Analyze test dependencies and coverage with get-usage-dependency-links
- Find connections between tests and source code with find-direct-connections
- Search for testing documentation and guidelines with docs-semantic-search
- Generate comprehensive test coverage report with improvement suggestions
This command is ideal for: test audits, coverage improvement, and testing strategy planning.
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.

test-coverage-analyzer is a command published in the GitHub repository diffbot/mcp-code-graph (402 stars, last pushed 11mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 182 tokens. 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.
