context-timeline
Real-time browser visualization of Claude Code's context window and subagent/tool execution as a git-graph timeline. Opens http://localhost:7878 on SessionStart with a vertical timeline (most recent on top), one column per agent (main + subagents branching from their Task tool call). Tool calls are color-coded by type (Read=green, Edit/Write=orange, Bash=red, Grep/Glob=cyan, Task=purple, Web=yellow, MCP=gray). Right sidebar shows context-window usage (tokens/200K) with cache_read/cache_creation/input/output breakdown plus per-subagent mini-context. Reads ~/.claude/projects/<encoded-cwd>/<session_id>.jsonl directly — no data replication, no network calls. Pure stdlib Python, zero pip dependencies. Persistent daemon HTTP server on port 7878 (auto-fallback 7879-7888 if busy; override with CONTEXT_TIMELINE_PORT env var). Watchdog auto-shutdown after 1h of inactivity. Disable browser auto-open with CONTEXT_TIMELINE_NO_BROWSER=1. Manual shutdown: python3 .claude/hooks/context-timeline.py --shutdown
context-timeline-2
context-timeline: Claude Code session visualizer. Modes (called by Claude Code hooks via stdin JSON): --server-start SessionStart hook — launch daemon + open browser --event <NAME> PreToolUse / PostToolUse / Stop hook — notify server --shutdown Kill daemon manually --run-server <PORT> Internal: daemon entry point (do not call directly)
conventional-commits
Enforce conventional commit message format for all git commits. Validates commit messages follow the pattern: type(scope): description. Supported types: feat, fix, docs, style, refactor, perf, test, chore, ci, build, revert. Ensures consistent commit history for changelog generation and semantic versioning.

❌ Invalid commit message format Your message: {commit_msg} Commit messages must follow Conventional Commits: type(scope): description Types: feat: New feature fix: Bug fix docs: Documentation changes style: Code style changes (formatting) refactor: Code refactoring perf: Performance improvements test: Adding or updating tests chore: Maintenance tasks ci: CI/CD changes build: Build system changes revert: Revert previous commit Examples: ✅ feat: add user authentication ✅ feat(auth): implement JWT tokens ✅ fix: resolve memory leak in parser ✅ fix(api): handle null responses ✅ docs: update API documentation Invalid: ❌ Added new feature (no type) ❌ feat:add feature (missing space after colon) ❌ feature: add login (wrong type, use 'feat') 💡 Tip: Start your message with one of the types above followed by a colon and space.
dangerous-command-blocker
Advanced protection against dangerous shell commands with multi-level security. Blocks catastrophic operations (rm -rf /, dd, mkfs), protects critical paths (.claude/, .git/, node_modules/), and warns about suspicious patterns. Features: catastrophic command blocking, critical path protection, smart pattern detection, and detailed safety messages.
debug-window
Auto Debug Log Viewer. Opens a live-tailing debug log window when Claude Code starts with --debug or -d flag. The window closes automatically on session end. To keep the debug window open after session ends, set DEBUG_WINDOW_AUTO_CLOSE_DISABLE=1 in your settings.json. Tested on Intel Mac. Supports macOS, Linux, and Windows (Git Bash/Cygwin). Contributions from other platform users are welcome.
deployment-health-monitor
Monitor deployment status, error rates, and performance metrics, sending notifications for failed deployments or performance degradation. Tracks Vercel deployment health, monitors build success/failure rates, and provides alerts for deployment issues. Setup: Export 'export VERCEL_TOKEN=your_token' and 'export VERCEL_PROJECT_ID=your_project_id' (get from vercel.com/account/tokens and Vercel dashboard).
desktop-notification-on-stop
Sends a native desktop notification when Claude Code finishes responding. Uses the Stop hook event so you get a single notification per response instead of one per tool call (which is very noisy with PostToolUse). Supports macOS (osascript) and Linux (notify-send). Useful when you switch to another window while Claude works — you'll get a notification when it's ready for your input.
discord-detailed-notifications
Send detailed Discord notifications with session information when Claude Code finishes. Includes working directory, session duration, and system info with rich embeds. Requires DISCORD_WEBHOOK_URL environment variable.
discord-error-notifications
Send Discord notifications when Claude Code encounters long-running operations or when tools take significant time. Helps monitor productivity and catch potential issues with rich embeds. Requires DISCORD_WEBHOOK_URL environment variable.
env-file-protection
Prevent writing to .env files using the if condition for lightweight filtering. Blocks any Write tool call targeting .env* files, protecting secrets from accidental overwrites. Uses the if field to avoid spawning a process unless the file pattern matches.
