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 | $0.00051 | $0.00319 |
| Opus 5 | $0.00026 | $0.00160 |
| Sonnet 5 | $0.00010 | $0.00064 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
tdmcp-coverage-writer 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 11d 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
tdmcp-coverage-writer
Use this skill when assigned a specific coverage gap.
Workflow
- Read the target implementation and the closest existing tests.
- Identify the behavior or branch that is currently untested.
- Add the smallest test that would fail if that behavior regressed.
- Use existing helpers such as
tests/helpers/tdMock.ts,KnowledgeBase,RecipeLibrary, andsilentLoggerinstead of inventing new scaffolding. - Run the narrow test and fix any real failure.
Assertions to prefer
- Real return text/JSON blocks from
CallToolResult. - Bridge request bodies captured by msw.
- Friendly
isErrorresults instead of thrown handler errors. - CLI stdout/stderr and exit status for user-facing commands.
- Resource URI and payload shape consumed by MCP clients.
Avoid
- Tests that only import a module to mark lines covered.
- Broad snapshots where a specific behavior assertion would do.
- New exclusions in coverage config.
- Rewriting production code unless the test exposes a real bug and the lead asked you to patch it.
Output
Report the changed files, command run, behavior covered, and any remaining branch or live-TD validation that is still unverified.
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.

tdmcp-coverage-writer is a skill published in the GitHub repository Pantani/tdmcp (39 stars, last pushed 26d ago), licensed MIT. It adds 51 tokens to every session and 319 once invoked, about $0.0003 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.
