 "title": "Prune duplicate regression tests in a large suite",
 "page_title": "How to prune duplicate regression tests in a large suite with Deslop GPT",
 "summary": "Remove self-justifying or overlapping tests while keeping distinct failure coverage.",
 "who": "A maintainer whose test suite has grown with overlapping agent-written tests and who wants a faster, clearer suite.",
 "problem": "Many tests check the same thing, and some only verify code that was written to satisfy them.",
 "outcome": "A reduced test set in which each remaining test protects a distinct success, rejection, error, or edge-case behavior.",
 "steps": [
  "Install the Skill in Codex with `$skill-installer` using https://github.com/MrZoyo/deslop-GPT/tree/v0.3.4/skills/deslop",
  "Open the target repository in Codex.",
  "Run `$deslop tests apply` to prioritize test signal and mutual-support test and code clusters. (inferred, check the README)",
  "Review each deleted test and confirm its behavior is covered elsewhere.",
  "Run the project's own test suite and confirm it still passes. (inferred, check the README)"
 ],
 "agent_prompt": "Using the deslop Skill from MrZoyo/deslop-GPT, run `$deslop tests apply` on <target-repo-path>. Expected output: a list of removed tests with their coverage rationale. Verify that the remaining test count drops and that the project's own test command still passes.",
 "agents": [
  "codex",
  "claude-code"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README says the Skill reduces test surface, not behavior surface, so a smaller suite is only good if the remaining tests still guard the same behavior.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "python",
 "requirements": [
  "A local git checkout of the target repository",
  "Codex or Claude Code installed",
  "Git, if you install the Skill from a local clone"
