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):

# 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:

{
  "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:

npx specweave init my-project
# Installs all plugins including specweave-github
# Hooks auto-register via hooks.json

Manual (Development)

For testing or development:

# Install plugin
/plugin install specweave-github

# Verify hook registration
cat ~/.claude/settings.json
# Should show specweave-github hooks registered

Testing

Test Hook Independently

# 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:

[2025-11-10] [GitHub] 🔗 GitHub sync hook fired
[2025-11-10] [GitHub] 🔄 Syncing to GitHub issue #42
[2025-11-10] [GitHub] 📊 Syncing task checkboxes to GitHub issue #42

Log Prefixes:

  • [GitHub] - All messages from this hook
  • 🔗 - Hook fired

  • 📊 - Syncing task data
  • ✅ - Success
  • ⚠️ - Warning (non-blocking failure)
  • ℹ️ - Info (skipped due to precondition)

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:

# 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:

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.
