benefriches: Skill for Claude Code

.claude/skills/e2e-coverage-check/SKILL.md

e2e-coverage-check is a skill for Claude Code from incubateur-ademe/benefriches. It costs 49 tokens per session (240 once invoked), scanned A, original, MIT.

A review of branch changes against main that checks whether end-to-end tests cover new or changed user flows. End-to-end tests verify a feature through the application as a user would use it.

In plain words
What is it for?
Use it after implementing a feature or before opening a pull request to decide which browser-based tests should be added or updated.
Why use it?
It highlights missing test coverage before a pull request is created, especially when changes affect screens, routes, controllers, or shared data structures.

Token cost

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.

Security

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

  1. Launch the e2e-coverage-checker agent 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.

  2. Relay the agent's report to the user exactly as produced. Do not summarize or modify it.

Changes

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.
