cc-sessions-hooks

Create hooks by implementing the core patterns for UserPromptSubmit, PreToolUse, PostToolUse, or SessionStart lifecycle points. The Skill guides you through proper structure, error handling, and atomic state mutations to enforce framework integrity and write-gating requirements safely.

Write-gating is a critical validation mechanism that controls when state mutations occur within the cc-sessions framework. It prevents unauthorized or unsafe writes by enforcing checks before tool execution and session state changes, ensuring DAIC discipline and framework safety.

Use atomic state mutation patterns provided by the Skill to prevent corruption when multiple hooks interact with shared session state. These patterns ensure consistent state access, proper execution ordering, and safety guardrails across hook lifecycle points.

Yes, PreToolUse hooks enable framework-level validation of task manifest format before any tool executes. This Skill provides patterns for implementing such validation while respecting DAIC modes and managing state safely.

Debug hook failures by checking execution order, state mutation atomicity, and DAIC mode compliance. The Skill covers error handling structures, state inspection techniques, and validation patterns specific to hook lifecycle points and framework requirements.

Intermediate understanding of state management and hooks is sufficient. The Skill provides structured guidance on basic and enforcement hook patterns, shared-state access, and safety guardrails without requiring expert-level framework internals knowledge.
