# Hyperflow Trace > Hyperflow debugging. Use for bugs, test failures, runtime errors, broken builds, or "this doesn't work" reports — verbs like debug, "fix it", solve, "why is X failing", "Y is broken", or a pasted stack trace. Systematic root-cause analysis before any patch — never blind-patch symptoms. - Skill: `jeremylongshore/hyperflow-trace` (Agent Skill) - Install (CLI): `npx skillmds@latest add jeremylongshore/hyperflow-trace` - Raw SKILL.md: https://api.skillmd.com/api/skills/jeremylongshore/hyperflow-trace/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: jeremylongshore (https://skillmd.com/u/jeremylongshore) - Updated: 2026-09-08 - Page: https://skillmd.com/skills/jeremylongshore/hyperflow-trace --- # hyperflow-trace — root-cause phase (Antigravity single-agent) Find the root cause before changing anything. Follow the `hyperflow` doctrine. ## Steps 1. **Reproduce / locate.** Read the error, stack trace, or failing test. Identify the exact failing line and the observed-vs-expected behavior. 2. **5 Whys.** Trace the causal chain backward — keep asking "why" until you reach the true cause, not a symptom. 3. **Hypotheses.** List the 2-4 most plausible causes. For each, state a cheap test (read a file, add a log, run one test) that confirms or rules it out. Test them — narrow to the real cause. 4. **Confirm** the root cause with evidence (a failing assertion, a value print, a reproduced path). Do not patch on a guess. 5. **Fix** the root cause minimally. Add or update a test that would have caught it (characterization test before behavior change). 6. **Verify**: re-run the failing case + the surrounding suite. Self-review the diff (L1-L3). Commit as `fix(): ` (conventional, lowercase). ## Rules - Never blind-patch a symptom to make an error message disappear. - No behavior change beyond the fix unless asked. - If the root cause is unclear after hypothesis testing, surface what you found and what's still unknown — don't ship a speculative patch. --- **Source:** [`jeremylongshore/claude-code-plugins-plus-skills`](https://github.com/jeremylongshore/claude-code-plugins-plus-skills) → `plugins/ai-agency/hyperflow/templates/antigravity/skills/hyperflow-trace/SKILL.md`
