80 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Runtime per-test healing with evidence: multi-attribute selector healing, environment-aware diagnosis, flake classification, quarantine management, and confidence-scored auto-repair. Goes beyond simple locator fallbacks to cover action-level healing, data healing, and observable repair workflows. Use when: "flaky test," "test stability," "self-healing locator," "broken locator recovery," "unreliable test," "quarantine flaky test." Not for: bulk regenerating selectors after a planned UI refactor…

Works with any agent that supports SKILL.md skills.

skills/test-reliability/SKILL.md, line 388- Reproduce the flake: `npx playwright test <spec> --repeat-each=20 --workers=4 --trace=on` — it must fail at least once before you trust any fix.
skills/test-reliability/SKILL.md, line 389- After fixing, prove stability: `npx playwright test <spec> --repeat-each=50 --workers=4` — require 50/50 passes, in CI conditions too.
skills/test-reliability/SKILL.md, line 390- Confirm quarantine routing: `npx playwright test --project=stable` excludes `@quarantine` tests and `--project=quarantine` runs only them.

if [ -e ~/.agents/skills/'test-reliability' ] || [ -L ~/.agents/skills/'test-reliability' ]; then echo 'A skill folder named test-reliability already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/petrkindlmann/qa-skills' "$d" && git -C "$d" checkout --quiet '62434253c2592f27b494609c27f224939c86346d' -- 'skills/test-reliability' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/test-reliability' ~/.agents/skills/'test-reliability' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'test-reliability' ~/.claude/skills/'test-reliability' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
