What problem does it solve?

It helps you design, validate, and orchestrate Claude Code hooks across the full lifecycle with deterministic behavior, precise matchers, correct exit-code contracts, and safety-oriented gating.

Core Features & Use Cases

• Lifecycle hook architecture: Build hook pipelines that intercept specific of Claude Code’s 17 lifecycle events (e.g., PreToolUse, PostToolUse, Stop) with precise matchers and handler types.
• Deterministic control & contracts: Enforce fail-safe execution using exit-code semantics (0 proceed, 2 block with feedback) and required human-readable stderr on blocks.
• Audit, patterns, and debugging: Audit coverage across settings, reference proven hook patterns, and debug hooks that fail to fire due to matcher/scope/permissions issues.
• Meta-agent hook generation: Generate hook sets and coordinated pipelines from requirements, including test harness generation.

Quick Start
