Install the hooks skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/parcadei/Continuous-Claude-v3.git /tmp/Continuous-Claude-v3
mkdir -p ~/.claude/skills
cp -r /tmp/Continuous-Claude-v3/.claude/skills/hooks ~/.claude/skills/hooks
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Hook Development Rules

When working with files in .claude/hooks/:

Pattern

Shell wrapper (.sh) → TypeScript (.ts) via npx tsx

Shell Wrapper Template

#!/bin/bash
set -e
cd "$CLAUDE_PROJECT_DIR/.claude/hooks"
cat | npx tsx <handler>.ts

TypeScript Handler Pattern

interface HookInput {
  // Event-specific fields
}

async function main() {
  const input: HookInput = JSON.parse(await readStdin());

  // Process input

  const output = {
    result: 'continue',  // or 'block'
    message: 'Optional system reminder'
  };

  console.log(JSON.stringify(output));
}

Hook Events

  • PreToolUse - Before tool execution (can block)
  • PostToolUse - After tool execution
  • UserPromptSubmit - Before processing user prompt
  • PreCompact - Before context compaction
  • SessionStart - On session start/resume/compact
  • Stop - When agent finishes

Testing

Test hooks manually:

echo '{"type": "resume"}' | .claude/hooks/session-start-continuity.sh

Registration

Add hooks to .claude/settings.json:

{
  "hooks": {
    "EventName": [{
      "matcher": ["pattern"],  // Optional
      "hooks": [{
        "type": "command",
        "command": "$CLAUDE_PROJECT_DIR/.claude/hooks/hook.sh"
      }]
    }]
  }
}
