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 | $0.00037 | $0.00347 |
| Opus 5.5 | $0.00015 | $0.00139 |
| Sonnet 5.5 | $0.00007 | $0.00069 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
api-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 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
/api-coverage — Map API Test Coverage
Type: API Description: Maps API endpoints against existing API tests, showing which endpoints and methods are tested and which are missing.
Input Format
Optional:
- A list of endpoints (pasted, OpenAPI/Swagger spec, or via connector)
- A feature scope
With no input, map all existing API specs under tests/api/.
Output Format
A coverage table:
| Endpoint | Method | Tested | Cases covered (success / auth / invalid / error) |
|---|
Plus a prioritized list of gaps with the suggested skill to close each.
Step-by-Step Instructions
- Enumerate every
*.api.spec.tsundertests/api/. - Parse each test to extract the endpoint, method, and which case types it covers (success / 401 / 400 / error).
- If an endpoint list or OpenAPI spec was provided, align tests to it; otherwise infer the endpoint set from existing tests.
- Mark each endpoint+method as fully tested, partially tested (missing case types), or untested.
- Render the coverage table.
- List gaps in priority order and recommend
/new-api-specto close each.
Rules
- A method isn't "covered" unless success, auth failure, and invalid input are all tested.
- Read specs, don't execute them.
- Be explicit about assumptions when no endpoint list is provided.
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.

api-coverage is a skill published in the GitHub repository kint4/autoframe (8 stars, last pushed 4mo ago), licensed MIT. It adds 37 tokens to every session and 347 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
