Skills

📖

c-data-structures

Use when implementing data structures in C including arrays, linked lists, trees, and hash tables with manual memory management.

📖

c-memory-management

Use when managing memory in C programs with malloc/free, pointers, and avoiding common memory safety pitfalls.

📖

c-systems-programming

Use when writing low-level system software in C requiring file I/O, process management, signals, and system calls.

Hooks

🔧

PostToolUse

Runs immediately after a tool completes successfully. Can validate outputs, log results, or trigger follow-up actions based on tool execution.

han hook run c format --async
🛑

Stop

Runs when the main Claude Code agent has finished responding. Can verify task completion, check quality gates, or ensure documentation requirements are met before the session ends.

han hook run c format --async
han hook run c build --async
🛑

SubagentStop

Runs when a Claude Code subagent (Agent tool call) has finished responding. Can validate subagent outputs, enforce quality standards, or trigger additional workflows after delegated tasks complete.

han hook run c format --async
han hook run c build --async
