# GSD Runbook

> Operational procedures for debugging, validation, and recovery.

---

## Quick Commands

### Status Check

**PowerShell:**
```powershell

# Current git status

git status



# Recent commits

git log --oneline -10



# Current branch

git branch --show-current

```

**Bash:**
```bash

# Current git status

git status



# Recent commits

git log --oneline -10



# Current branch

git branch --show-current

```

---

## Wave Validation

### Verify Wave Completion

**Before marking a wave complete:**

1. All tasks have commits:
   ```powershell

   git log --oneline -N  # N = number of tasks in wave

   ```

2. All verifications passed (documented in SUMMARY.md)

3. STATE.md updated with current position

4. State snapshot created

### Wave Rollback

**If a wave needs to be reverted:**

```powershell

# Find commit before wave started

git log --oneline -20



# Reset to that commit (keeps changes staged)

git reset --soft <commit-hash>



# Or hard reset (discards changes)

git reset --hard <commit-hash>

```

---

## Debugging Procedures

### 3-Strike Rule

After 3 consecutive failed debug attempts:

1. **Stop** — Don't try a 4th approach in same session

2. **Document** in STATE.md:
   ```markdown

   ## Debug Session

   

   **Problem:** {description}

   

   **Attempts:**

   1. {approach 1} → {result}

   2. {approach 2} → {result}

   3. {approach 3} → {result}

   

   **Hypothesis:** {current theory}

   

   **Recommended next:** {suggested approach}

   ```

3. **Fresh session** — Start new conversation with documented context

### Log Inspection

**Find relevant logs:**

```powershell

# Search for error patterns

Select-String -Path "*.log" -Pattern "error|exception|failed" -CaseSensitive:$false

```

```bash

# Search for error patterns

grep -ri "error\|exception\|failed" *.log

```

---

## Verification Commands

### Build Verification

```powershell

# Node.js

npm run build

if ($LASTEXITCODE -eq 0) { Write-Host "✅ Build passed" }



# Python

python -m py_compile src/**/*.py

```

### Test Verification

```powershell

# Node.js

npm test



# Python

pytest -v



# Go

go test ./...

```

### Lint Verification

```powershell

# Node.js

npm run lint



# Python

ruff check .



# Go

golangci-lint run

```

---

## State Recovery

### From STATE.md

When resuming work:

1. Read STATE.md for current position
2. Check "Last Action" for context
3. Follow "Next Steps" to continue
4. Verify recent commits match documented progress

### From Git History

If STATE.md is outdated:

```powershell

# See recent work

git log --oneline -20



# Check specific commit details

git show <commit-hash> --stat



# View file at specific commit

git show <commit-hash>:path/to/file

```

### Context Pollution Recovery

If quality is degrading mid-session:

1. Create state snapshot immediately
2. Update STATE.md with full context
3. Commit any pending work
4. Start fresh session
5. Run `/resume` to reload context

---

## Search Commands

### Find in Codebase

**PowerShell:**
```powershell

# Find pattern in files

Select-String -Path "src/**/*.ts" -Pattern "TODO" -Recurse



# Find files by name

Get-ChildItem -Recurse -Filter "*.config.*"

```

**Bash:**
```bash

# Find pattern in files (with ripgrep)

rg "TODO" --type ts



# Find pattern in files (with grep)

grep -r "TODO" src/



# Find files by name

find . -name "*.config.*"

```

### Search-First Workflow

Before reading any file:

1. Search for relevant terms:
   ```powershell

   Select-String -Path "**/*.md" -Pattern "architecture" -Recurse

   ```

2. Identify candidate files from results

3. Read only relevant sections:
   ```powershell

   Get-Content file.md | Select-Object -Skip 49 -First 20  # Lines 50-70

   ```

---

## Common Issues

### "SPEC.md not FINALIZED"

**Cause:** Planning lock prevents implementation

**Fix:**
1. Open `.gsd/SPEC.md`
2. Complete all required sections
3. Change status to `Status: FINALIZED`
4. Retry command

### "Context degrading"

**Symptoms:** Shorter responses, skipped steps, inconsistency

**Fix:**
1. Create state snapshot
2. Commit current work
3. Start fresh session
4. Run `/resume`

### "Commit failed"

**Causes:** Staged conflicts, hook failures

**Debug:**
```powershell

git status

git diff --staged

```
