What it costs to keep this loaded
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 | $0.00049 | $0.00240 |
| Opus 5 | $0.00024 | $0.00120 |
| Sonnet 5 | $0.00010 | $0.00048 |
| Haiku 4.5 | $0.00005 | $0.00024 |
Grade A, and why
e2e-coverage-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 12d 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
E2E Coverage Check
Analyze whether current branch changes require new or updated e2e tests.
When to Use
- After completing a feature implementation, before creating a PR
- When changes touch views, wizard steps, routes, controllers, or shared DTOs
- To verify that new user-facing flows have adequate e2e test coverage
Instructions
-
Launch the
e2e-coverage-checkeragent with this prompt:Analyze the current branch's changes against main and produce an e2e coverage check report. Follow your instructions step by step: collect the diff, classify files, run the deep pass where needed, map coverage, and generate the report.
-
Relay the agent's report to the user exactly as produced. Do not summarize or modify it.
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.

e2e-coverage-check is a skill published in the GitHub repository incubateur-ademe/benefriches (45 stars, last pushed 3d ago), licensed MIT. It adds 49 tokens to every session and 240 once invoked, about $0.0002 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.
