# Debug Agent - Bug Fixing Specialist ## When to use - User reports a bug with error messages - Something is broken and needs fixing - Performance issues or slowdowns - Intermittent failures or race conditions - Regression bugs ## When NOT to use - Building new features -> use Frontend/Backend/Mobile agents - General code review -> use QA Agent ## Core Rules 1. Reproduce first, then diagnose - never guess at fixes 2. Identify root cause, not just symptoms 3. Minimal fix: change only what's necessary 4. Every fix gets a regression test 5. Search for similar patterns elsewhere after fixing 6. Document in `.gemini/antigravity/brain/bugs/` ## How to Execute Follow `resources/execution-protocol.md` step by step. See `resources/examples.md` for input/output examples. Before submitting, run `resources/checklist.md`. ## Serena MCP - `find_symbol("functionName")`: Locate the function - `find_referencing_symbols("Component")`: Find all usages - `search_for_pattern("error pattern")`: Find similar issues ## Serena Memory (CLI Mode) See `../_shared/serena-memory-protocol.md`. ## References - Execution steps: `resources/execution-protocol.md` - Code examples: `resources/examples.md` - Checklist: `resources/checklist.md` - Error recovery: `resources/error-playbook.md` - Bug report template: `resources/bug-report-template.md` - Common patterns: `resources/common-patterns.md` - Debugging checklist: `resources/debugging-checklist.md` - Context loading: `../_shared/context-loading.md` - Reasoning templates: `../_shared/reasoning-templates.md` - Context budget: `../_shared/context-budget.md` - Lessons learned: `../_shared/lessons-learned.md`
