Quick patches mask underlying issues.\n\n**Core principle:** ALWAYS find root cause before attempting fixes. Symptom fixes are failure.\n\n**Violating the letter of this process is violating the spirit of debugging.**\n\n## The Iron Law\n\n```\nNO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST\n```\n\nIf you haven't completed Phase 1, you cannot propose fixes.\n\n## When to Use\n\nUse for ANY technical issue:\n- Test failures\n- Bugs in production\n- Unexpected behavior\n- Performance problems\n- Build failures\n- Integration issues\n\n**Use this ESPECIALLY when:**\n- Under time pressure (emergencies make guessing tempting)\n- \"Just one quick fix\" seems obvious\n- You've already tried multiple fixes\n- Previous fix didn't work\n- You don't fully understand the issue\n\n**Don't skip when:**\n- Issue seems simple (simple bugs have root causes too)\n- You're in a hurry (rushing guarantees rework)\n- Manager wants it fixed NOW (systematic is faster than thrashing)\n\n## The Four Phases\n\nYou MUST complete each phase before proceeding to the next.\n\n### Phase 1: Root Cause Investigation\n\n**BEFORE attempting ANY fix:**\n\n1. **Read Error Messages Carefully**\n   - Don't skip past errors or warnings\n   - They often contain the exact solution\n   - Read stack traces completely\n   - Note line numbers, file paths, error codes\n\n2. **Reproduce Consistently**\n   - Can you trigger it reliably?\n   - What are the exact steps?\n   - Does it happen every time?\n   - If not reproducible \u2192 gather more data, don't guess\n\n3. **Check Recent Changes**\n   - What changed that could cause this?\n   - Git diff, recent commits\n   - New dependencies, config changes\n   - Environmental differences\n\n4. **Gather Evidence in Multi-Component Systems**\n\n   **WHEN system has multiple components (CI \u2192 build \u2192 signing, API \u2192 service \u2192 database):**\n\n   **BEFORE proposing fixes, add diagnostic instrumentation:**\n   ```\n   For EACH component boundary:\n     - Log what data enters component\n     - Log what data exits component\n     - Verify environment/config propagation\n     - Check state at each layer\n\n   Run once to gather evidence showing WHERE it breaks\n   THEN analyze evidence to identify failing component\n   THEN investigate that specific component\n   ```\n\n   **Example (multi-layer system):**\n   ```bash\n   # Layer 1: Workflow\n   echo \"=== Secrets available in workflow: ===\"\n   echo \"IDENTITY: ${IDENTITY:+SET}${IDENTITY:-UNSET}\"\n\n   # Layer 2: Build script\n   echo \"=== Env vars in build script: ===\"\n   env | grep IDENTITY || echo \"IDENTITY not in environment\"\n\n   # Layer 3: Signing script\n   echo \"=== Keychain state: ===\"\n   security list-keychains\n   security find-identity -v\n\n   # Layer 4: Actual signing\n   codesign --sign \"$IDENTITY\" --verbose=4 \"$APP\"\n   ```\n\n   **This reveals:** Which layer fails (secrets \u2192 workflow \u2713, workflow \u2192 build \u2717)\n\n5. **Trace Data Flow**\n\n   **WHEN error is deep in call stack:**\n\n   See `root-cause-tracing.md` in this directory for the complete backward tracing technique.\n\n   **Quick version:**\n   - Where does bad value originate?\n   - What called this with bad value?\n   - Keep tracing up until you find the source\n   - Fix at source, not at symptom\n\n### Phase 2: Pattern Analysis\n\n**Find the pattern before fixing:**\n\n1. **Find Working Examples**\n   - Locate similar working code in same codebase\n   - What works that's similar to what's broken?\n\n2. **Compare Against References**\n   - If implementing pattern, read reference implementation COMPLETELY\n   - Don't skim - read every line\n   - Understand the pattern fully before applying\n\n3. **Identify Differences**\n   - What's different between working and broken?\n   - List every difference, however small\n   - Don't assume \"that can't matter\"\n\n4. **Understand Dependencies**\n   - What other components does this need?\n   - What settings, config, environment?\n   - What assumptions does it make?\n\n### Phase 3: Hypothesis and Testing\n\n**Scientific method:**\n\n1. **Form Single Hypothesis**\n   - State clearly: \"I think X is the root cause because Y\"\n   - Write it down\n   - Be specific, not vague\n\n2. **Test Minimally**\n   - Make the SMALLEST possible change to test hypothesis\n   - One variable at a time\n   - Don't fix multiple things at once\n\n3. **Verify Before Continuing**\n   - Did it work? Yes \u2192 Phase 4\n   - Didn't work? Form NEW hypothesis\n   - DON'T add more fixes on top\n\n4. **When You Don't Know**\n   - Say \"I don't understand X\"\n   - Don't pretend to know\n   - Ask for help\n   - Research more\n\n### Phase 4: Implementation\n\n**Fix the root cause, not the symptom:**\n\n1. **Create Failing Test Case**\n   - Simplest possible reproduction\n   - Automated test if possible\n   - One-off test script if no framework\n   - MUST have before fixing\n   - Use the `superpowers:test-driven-development` skill for writing proper failing tests\n\n2. **Implement Single Fix**\n   - Address the root cause identified\n   - ONE change at a time\n   - No \"while I'm here\" improvements\n   - No bundled refactoring\n\n3. **Verify Fix**\n   - Test passes now?\n   - No other tests broken?\n   - Issue actually resolved?\n\n4. **If Fix Doesn't Work**\n   - STOP\n   - Count: How many fixes have you tried?\n   - If < 3: Return to Phase 1, re-analyze with new information\n   - **If \u2265 3: STOP and question the architecture (step 5 below)**\n   - DON'T attempt Fix #4 without architectural discussion\n\n5. **If 3+ Fixes Failed: Question Architecture**\n\n   **Pattern indicating architectural problem:**\n   - Each fix reveals new shared state/coupling/problem in different place\n   - Fixes require \"massive refactoring\" to implement\n   - Each fix creates new symptoms elsewhere\n\n   **STOP and question fundamentals:**\n   - Is this pattern fundamentally sound?\n   - Are we \"sticking with it through sheer inertia\"?\n   - Should we refactor architecture vs. continue fixing symptoms?\n\n   **Discuss with your human partner before attempting more fixes**\n\n   This is NOT a failed hypothesis - this is a wrong architecture.\n\n## Red Flags - STOP and Follow Process\n\nIf you catch yourself thinking:\n- \"Quick fix for now, investigate later\"\n- \"Just try changing X and see if it works\"\n- \"Add multiple changes, run tests\"\n- \"Skip the test, I'll manually verify\"\n- \"It's probably X, let me fix that\"\n- \"I don't fully understand but this might work\"\n- \"Pattern says X but I'll adapt it differently\"\n- \"Here are the main problems: [lists fixes without investigation]\"\n- Proposing solutions before tracing data flow\n- **\"One more fix attempt\" (when already tried 2+)**\n- **Each fix reveals new problem in different place**\n\n**ALL of these mean: STOP. Return to Phase 1.**\n\n**If 3+ fixes failed:** Question the architecture (see Phase 4.5)\n\n## your human partner's Signals You're Doing It Wrong\n\n**Watch for these redirections:**\n- \"Is that not happening?\" - You assumed without verifying\n- \"Will it show us...?\" - You should have added evidence gathering\n- \"Stop guessing\" - You're proposing fixes without understanding\n- \"Ultrathink this\" - Question fundamentals, not just symptoms\n- \"We're stuck?\" (frustrated) - Your approach isn't working\n\n**When you see these:** STOP. Return to Phase 1.\n\n## Common Rationalizations\n\n| Excuse | Reality |\n|--------|---------|\n| \"Issue is simple, don't need process\" | Simple issues have root causes too. Process is fast for simple bugs. |\n| \"Emergency, no time for process\" | Systematic debugging is FASTER than guess-and-check thrashing. |\n| \"Just try this first, then investigate\" | First fix sets the pattern. Do it right from the start. |\n| \"I'll write test after confirming fix works\" | Untested fixes don't stick. Test first proves it. |\n| \"Multiple fixes at once saves time\" | Can't isolate what worked. Causes new bugs. |\n| \"Reference too long, I'll adapt the pattern\" | Partial understanding guarantees bugs. Read it completely. |\n| \"I see the problem, let me fix it\" | Seeing symptoms \u2260 understanding root cause. |\n| \"One more fix attempt\" (after 2+ failures) | 3+ failures = architectural problem. Question pattern, don't fix again. |\n\n## Quick Reference\n\n| Phase | Key Activities | Success Criteria |\n|-------|---------------|------------------|\n| **1. Root Cause** | Read errors, reproduce, check changes, gather evidence | Understand WHAT and WHY |\n| **2. Pattern** | Find working examples, compare | Identify differences |\n| **3. Hypothesis** | Form theory, test minimally | Confirmed or new hypothesis |\n| **4. Implementation** | Create test, fix, verify | Bug resolved, tests pass |\n\n## When Process Reveals \"No Root Cause\"\n\nIf systematic investigation reveals issue is truly environmental, timing-dependent, or external:\n\n1. You've completed the process\n2. Document what you investigated\n3. Implement appropriate handling (retry, timeout, error message)\n4. Add monitoring/logging for future investigation\n\n**But:** 95% of \"no root cause\" cases are incomplete investigation.\n\n## Supporting Techniques\n\nThese techniques are part of systematic debugging and available in this directory:\n\n- **`root-cause-tracing.md`** - Trace bugs backward through call stack to find original trigger\n- **`defense-in-depth.md`** - Add validation at multiple layers after finding root cause\n- **`condition-based-waiting.md`** - Replace arbitrary timeouts with condition polling\n\n**Related skills:**\n- **superpowers:test-driven-development** - For creating failing test case (Phase 4, Step 1)\n- **superpowers:verification-before-completion** - Verify fix worked before claiming success\n\n## Real-World Impact\n\nFrom debugging sessions:\n- Systematic approach: 15-30 minutes to fix\n- Random fixes approach: 2-3 hours of thrashing\n- First-time fix rate: 95% vs 40%\n- New bugs introduced: Near zero vs common\n"}]}, "parent_tool_use_id": null, "session_id": "0fe6532b-6f59-4e85-8f16-c851dbe639b3", "uuid": "7affa242-ba5a-4e8a-b87d-962bf10222f5", "timestamp": "2026-08-21T17:20:44.247Z", "isSynthetic": true}
