-### Step 1: Assess & Isolate -□ Verify the issue is reproducible -□ Check error logs/monitoring for root cause indicators -□ Estimate blast radius (how many users affected) -□ Create incident channel/ticket - -### Step 2: Environment Setup -□ Create hotfix branch: `git checkout -b hotfix/[issue-name]` -□ Pull latest production: `git pull origin main` -□ Verify local environment matches production -□ Document current state (git commit hash, deployment time) - -### Step 3: Context Preparation -□ Open Claude Code in project root -□ Set explicit scope: "Working on hotfix for [issue]" -□ Use Plan Mode first: `/plan` (safer for critical changes) -□ Load relevant error logs/stack traces -``` - -### Hotfix Development (5-15 minutes) - -```markdown -### Step 4: Fix Implementation -□ Use Claude to locate issue: "Find where [error] occurs" -□ Review proposed fix carefully (critical code path) -□ Prefer minimal changes (smaller diff = lower risk) -□ Add defensive checks if time permits - -### Step 5: Immediate Verification -□ Run affected test suite: `npm test [related tests]` -□ Manual smoke test of fixed functionality -□ Test edge cases that triggered the issue -□ Verify no regression in related features -``` - -### Post-Fix Phase (5-10 minutes) - -```markdown -### Step 6: Commit & Deploy -□ Create focused commit: `git add [changed files]` -□ Write clear commit message: - "hotfix: [verb] [what was broken] - - - Root cause: [brief explanation] - - Fix: [what changed] - - Tested: [how verified] - - Fixes #[incident-number]" - -□ Push hotfix branch: `git push origin hotfix/[issue-name]` -□ Create PR with "HOTFIX" label -□ Tag reviewer(s) for immediate review -□ Include before/after behavior in PR description - -### Step 7: Deploy & Monitor -□ Deploy to staging first if possible (even for hotfixes) -□ Monitor staging for 2-3 minutes -□ Deploy to production -□ Watch error rates/logs for 5-10 minutes -□ Verify issue is resolved in production -□ Update incident channel/ticket - -### Step 8: Post-Mortem (Schedule later) -□ Document root cause analysis -□ Identify why this wasn't caught earlier -□ Add tests/monitoring to prevent recurrence -□ Update CLAUDE.md with lessons learned -□ Schedule team discussion if systemic issue -``` - -### Hotfix Anti-Patterns - -| ❌ Don't | ✅ Do | -|---------|------| -| Skip tests "to save time" | Run at minimum the affected tests | -| Make "while we're here" improvements | Fix ONLY the immediate issue | -| Deploy without code review | Get at least one approval (async if urgent) | -| Forget to monitor after deploy | Watch for 10+ minutes post-deploy | -| Skip documentation | Update incident log immediately | -| Work on main branch | Always use hotfix branch | - -### Time-Based Decision Matrix - -| Time Available | Approach | -|----------------|----------| -| **< 5 min** | Rollback to previous version, fix properly later | -| **5-15 min** | Minimal fix, comprehensive testing later | -| **15-30 min** | Proper fix with tests, still monitor closely | -| **> 30 min** | Not a hotfix, follow normal development process | - -### Claude Code Hotfix Commands - -```markdown -# Use Plan Mode for safety -/plan - -# Ask Claude to assess -"Analyze this error log and suggest the safest minimal fix" - -# Get focused context -"Read only the [affected module], not the entire codebase" -

-| Question | Traditional Approach | Git Archaeology Approach | -|----------|---------------------|-------------------------| -| Why this weird workaround? | Guess or ask someone | Check commit that added it | -| Why was this refactored? | Search Slack/docs | Read PR description | -| When did this bug appear? | Binary search testing | `git bisect` with Claude | -| Who knows this code? | Check Slack or guess | See commit authors | - -### Pattern 1: Understanding Mysterious Code - -**Scenario**: You found confusing code and want to know why it exists. - -```markdown -# Step 1: Find the commit -You: "Run git blame on [file:line] to find when this code was added" - -# Step 2: Get commit context -You: "Show me the full commit with git show [commit-hash]" - -# Step 3: Find related discussion -You: "Search for the PR or issue related to this commit" - -# Step 4: Summarize -You: "Explain why this code exists based on the commit history" -``` - -**Example**: - -``` -You: Why does user.ts:45 have this strange null check? - -Claude: Let me investigate... -- Runs: git blame src/user.ts -- Finds commit: abc123 "fix: handle legacy user objects" -- Reads commit message: "Older user records don't have email field" -- Conclusion: It's a backward compatibility fix from 2023 migration -``` - -### Pattern 2: Tracking Feature Evolution - -**Scenario**: Understand how a feature evolved over time. - -```markdown -# Get all commits related to a feature -You: "Find all commits that mention 'authentication' in the last 6 months" - -Claude runs: -git log --grep="authentication" --since="6 months ago" --oneline - -# Analyze the evolution -You: "Summarize how authentication changed over these commits" - -Claude provides timeline: -- Jan: Initial OAuth implementation -- Feb: Added 2FA support -- Mar: Migrated to JWT -- Apr: Added session refresh -``` - -### Pattern 3: Finding When Bugs Were Introduced - -**Scenario**: A bug exists now but didn't before. Find when it appeared. - -```markdown -# Manual approach -You: "Help me use git bisect to find when [bug] was introduced" - -Claude guides you: -1. git bisect start -2. git bisect bad [current commit] -3. git bisect good [known good commit] -4. Claude tests each bisect step -5. Identifies the breaking commit - -# Automated with Claude -You: "Write a script to test if [bug] exists, then use git bisect run" - -Claude creates: -- Test script that exits 0 (good) or 1 (bad) -- Runs git bisect automatically -- Reports the exact commit that introduced the bug -``` - -### Pattern 4: Finding Domain Experts - -**Scenario**: Who should review this code? - -```markdown -You: "Who has worked on [file/directory] most?" - -Claude runs: -git shortlog -sn -- [path] - -Result: -42 Alice Johnson -18 Bob Smith -5 Carol White - -Interpretation: Alice is the domain expert -``` - -### Pattern 5: Understanding Deleted Code - -**Scenario**: Code was deleted but you want to understand what it did. - -```markdown -# Find when code was deleted -You: "Search git history for when [function name] was removed" - -Claude runs: -git log -c -S'[function name]' --all - -# Restore and analyze -You: "Show me what [function name] did before it was deleted" - -Claude: -1. Finds the deletion commit -2. Shows commit^ (before deletion) -3. Extracts and explains the old implementation -4. Explains why it was removed (from commit message) -``` - -### Pattern 6: Comparing Implementations - -**Scenario**: The code changed drastically. Why? - -```markdown -You: "Compare how [feature] was implemented in: -- Current version -- Version from 6 months ago" - -Claude: -1. git show HEAD:[file] -2. git show HEAD~6mo:[file] -3. Highlights key differences -4.
