Test Suite Audit skill for Claude and Codex

Test Suite Audit as an AI skill. It asks for Project and language, Test location and command, Suite pain points and 3 more, then does the rest. Free to…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when a team has a slow, flaky, or bloated test suite and wants to know which tests to cut and which flows lack protection, without any edits. Do not use for writing new tests or fixing a specific failing test. Related topics: coding, technical.

What it will ask you for

• Project and language (free text, e.g. "Python web API")
• Test location and command (free text, e.g. "Folder and run command")
• Suite pain points (longer free text)
• Run time of the full suite (free text, e.g. "Minutes")
• Most critical user flows (longer free text)
• Report detail (choose one: Summary, Detailed)

How it works

1. Read the tests and group them by area, noting runtime and flakiness evidence.
2. Score each group on cost signals against protection signals.
3. List tests that cost more than they protect with a recommendation to delete, merge, or rewrite.
4. Map the critical flows to existing tests and rank the gaps by damage if they fail.
5. Close with five prioritised actions and the estimated run time saved, making no code changes.

What you get

A report with a cost versus protection table, a list of tests to delete merge or rewrite, a ranked gap list for critical flows, and five prioritised actions.

What it watches out for

• Using line coverage as the measure, which rewards trivial tests.
• Recommending deletion of slow tests that guard a critical flow.
• Editing files during an audit that was meant to be read-only.
