# SpecWeave GitHub Plugin Hooks
|
||||
|
||||
**Plugin**: `specweave-github`
|
||||
**Location**: `plugins/specweave-github/hooks/`
|
||||
|
||||
---
|
||||
|
||||
## Purpose
|
||||
|
||||
This hook provides GitHub Issues sync functionality for SpecWeave increments.
|
||||
|
||||
**Key Features**:
|
||||
- ✅ Updates GitHub issue checkboxes based on `tasks.md` completion status
|
||||
- ✅ Posts progress comments with percentage completion
|
||||
- ✅ Bidirectional sync (local → GitHub)
|
||||
- ✅ Non-blocking (failures don't stop core workflow)
|
||||
- ✅ Self-contained (no dependencies on core plugin)
|
||||
|
||||
**IMPORTANT CHANGE (v0.26.0)**: This hook is NO LONGER automatically triggered on task completion. GitHub sync should be done manually or on increment completion to avoid excessive API calls and performance overhead.
|
||||
|
||||
---
|
||||
|
||||
## Available Hooks
|
||||
|
||||
### 1. `post-task-completion.sh`
|
||||
|
||||
**Triggers**: Manual invocation or increment completion (NOT on task completion)
|
||||
|
||||
**Preconditions**:
|
||||
- ✅ Active increment exists (`.specweave/increments/####/`)
|
||||
- ✅ `metadata.json` has `.github.issue` field
|
||||
- ✅ GitHub CLI (`gh`) installed and authenticated
|
||||
- ✅ `tasks.md` file exists in increment
|
||||
|
||||
**Actions**:
|
||||
1. Reads completed tasks from `tasks.md`
|
||||
2. Fetches GitHub issue body
|
||||
3. Updates checkboxes for completed tasks
|
||||
4. Posts progress comment with percentage
|
||||
5. Logs all actions to `.specweave/logs/hooks-debug.log`
|
||||
|
||||
**Example Flow**:
|
||||
```
|
||||
Task T-003 completed in tasks.md
|
||||
↓
|
||||
Hook fires (PostToolUse + TodoWrite matcher)
|
||||
↓
|
||||
GitHub issue #42 checkboxes updated: [ ] T-003 → [x] T-003
|
||||
↓
|
||||
Progress comment posted: "Progress Update: 3/5 tasks (60%)"
|
||||
↓
|
||||
Log: "[GitHub] ✅ GitHub sync complete"
|
||||
```
|
||||
|
||||
**Dependencies**:
|
||||
- `gh` CLI (GitHub CLI)
|
||||
- `jq` for JSON parsing
|
||||
- Bash 4.0+
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
### Hook Registration
|
||||
|
||||
**DEPRECATED (v0.26.0)**: This hook is NO LONGER automatically registered on TodoWrite events.
|
||||
|
||||
**Previous behavior (v0.24.0 and earlier)**:
|
||||
- Hook automatically fired on EVERY task completion
|
||||
- Caused excessive GitHub API calls
|
||||
- Created performance overhead and duplicate executions
|
||||
|
||||
**New behavior (v0.26.0+)**:
|
||||
- Hook must be invoked manually via `/specweave-github:sync`
|
||||
- OR triggered on increment completion (not task completion)
|
||||
- Reduces API calls by 90%+
|
||||
- Eliminates duplicate hook executions
|
||||
|
||||
### Usage
|
||||
|
||||
**Manual Sync** (recommended workflow):
|
||||
```bash
|
||||
# After completing several tasks, sync progress to GitHub
|
||||
/specweave-github:sync
|
||||
|
||||
# Or sync specific feature
|
||||
/specweave-github:sync FS-048
|
||||
```
|
||||
|
||||
**Automatic Sync Options**:
|
||||
1. **On Increment Completion**: Add hook to specweave plugin's post-increment-completion
|
||||
2. **Periodic Sync**: Set up cron job or CI/CD trigger
|
||||
3. **On Demand**: Call `/specweave-github:sync` when needed
|
||||
|
||||
### Metadata Format
|
||||
|
||||
Increments must have `metadata.json` with GitHub issue link:
|
||||
|
||||
```json
|
||||
{
|
||||
"github": {
|
||||
"issue": 42,
|
||||
"url": "https://github.com/owner/repo/issues/42",
|
||||
"repo": "owner/repo"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Installation
|
||||
|
||||
### Automatic (Recommended)
|
||||
|
||||
When `specweave init` runs, all plugin hooks are automatically installed:
|
||||
|
||||
```bash
|
||||
npx specweave init my-project
|
||||
# Installs all plugins including specweave-github
|
||||
# Hooks auto-register via hooks.json
|
||||
```
|
||||
|
||||
### Manual (Development)
|
||||
|
||||
For testing or development:
|
||||
|
||||
```bash
|
||||
# Install plugin
|
||||
/plugin install specweave-github
|
||||
|
||||
# Verify hook registration
|
||||
cat ~/.claude/settings.json
|
||||
# Should show specweave-github hooks registered
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Hook Independently
|
||||
|
||||
```bash
|
||||
# Test syntax
|
||||
bash -n plugins/specweave-github/hooks/post-task-completion.sh
|
||||
|
||||
# Test execution (requires active increment + GitHub issue)
|
||||
./plugins/specweave-github/hooks/post-task-completion.sh
|
||||
```
|
||||
|
||||
### Test with GitHub Issue
|
||||
|
||||
1. Create increment: `/specweave:increment "test feature"`
|
||||
2. Create GitHub issue: `/specweave-github:create-issue 0001`
|
||||
3. Complete several tasks via TodoWrite
|
||||
4. **Manually trigger sync**: `/specweave-github:sync`
|
||||
5. Check GitHub issue for updates
|
||||
|
||||

|
||||
|
||||
## Logging
|
||||
|
||||
All GitHub sync actions are logged to:
|
||||
|
||||
```
|
||||
.specweave/logs/hooks-debug.log
|
||||
```
|
||||
|
||||
**Example Log Output**:
|
||||
```

## Architecture
|
||||
|
||||
### How It Works with Core Plugin
|
||||
|
||||
**Before (v0.12.x)**:
|
||||
```
|
||||
Core hook (500+ lines)
|
||||
├── Sound notifications
|
||||
├── Living docs sync
|
||||
├── Translation
|
||||
├── GitHub sync ← Embedded in core!
|
||||
├── JIRA sync ← Embedded in core!
|
||||
└── ADO sync ← Embedded in core!
|
||||
```
|
||||
|
||||
**After (v0.13.0+)**:
|
||||
```
|
||||
Core hook (330 lines) GitHub plugin hook (241 lines)
|
||||
├── Sound notifications ├── Check for GitHub issue
|
||||
├── Living docs sync ├── Update checkboxes
|
||||
├── Translation ├── Post progress comment
|
||||
└── Self-reflection └── Log actions
|
||||
```
|
||||
|
||||
**Key Benefits**:
|
||||
- ✅ **Separation of concerns**: Core plugin has NO external tool dependencies
|
||||
- ✅ **Optional plugin**: GitHub sync only runs if `specweave-github` installed
|
||||
- ✅ **Independent testing**: Test GitHub sync in isolation
|
||||
- ✅ **Cleaner code**: Each hook <250 lines, single responsibility
|
||||
- ✅ **Parallel execution**: Claude Code runs all hooks concurrently
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Hook Not Firing
|
||||
|
||||
**Check**:
|
||||
1. Plugin installed: `/plugin list --installed | grep specweave-github`
|
||||
2. Hook registered: `cat ~/.claude/settings.json | grep specweave-github`
|
||||
3. Active increment: `cat .specweave/logs/current-increment`
|
||||
4. GitHub issue linked: `cat .specweave/increments/####/metadata.json | jq .github`
|
||||
|
||||
### GitHub CLI Not Found
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
# macOS
|
||||
brew install gh
|
||||
|
||||
# Linux
|
||||
curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
|
||||
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
|
||||
sudo apt update
|
||||
sudo apt install gh
|
||||
|
||||
# Authenticate
|
||||
gh auth login
|
||||
```
|
||||
|
||||
### Sync Failures
|
||||
|
||||
**Check logs**:
|
||||
```bash
|
||||
tail -f .specweave/logs/hooks-debug.log | grep '\[GitHub\]'
|
||||
```
|
||||
|
||||
**Common issues**:
|
||||
- ❌ No `metadata.json`: Create GitHub issue via `/specweave-github:create-issue`
|
||||
- ❌ Not authenticated: Run `gh auth login`
|
||||
- ❌ Invalid issue number: Check `metadata.json` has correct issue ID
|
||||
- ❌ Network error: Check internet connection
|
||||
|
||||

|
||||
|
||||
## Migration from v0.12.x
|
||||
|
||||
If upgrading from SpecWeave v0.12.x or earlier:
|
||||
|
||||
1. **Automatic**: Run `specweave init` (re-installs all hooks)
|
||||
2. **Manual**: Copy `plugins/specweave-github/hooks/` to `.claude/hooks/` (not recommended)
|
||||
|
||||
**No action needed**: Existing increments with GitHub issues will continue to sync automatically.
