+# Hook Setup Guide
+
+Configure automatic self-improvement triggers for AI coding agents.
+
+## Overview
+
+Hooks enable proactive learning capture by injecting reminders at key moments:
+- **UserPromptSubmit**: Reminder after each prompt to evaluate learnings
+- **PostToolUse (Bash)**: Error detection when commands fail
+
+## Claude Code Setup
+
+### Option 1: Project-Level Configuration
+
+Create `.claude/settings.json` in your project root:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "matcher": "",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "./skills/self-improvement/scripts/activator.sh"
+          }
+        ]
+      }
+    ],
+    "PostToolUse": [
+      {
+        "matcher": "Bash",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "./skills/self-improvement/scripts/error-detector.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Option 2: User-Level Configuration
+
+Add to `~/.claude/settings.json` for global activation:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "matcher": "",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "~/.claude/skills/self-improvement/scripts/activator.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Minimal Setup (Activator Only)
+
+For lower overhead, use only the UserPromptSubmit hook:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "matcher": "",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "./skills/self-improvement/scripts/activator.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Codex CLI Setup
+
+Codex uses the same hook system as Claude Code. Create `.codex/settings.json`:
+
+```json
+{
+  "hooks": {
+    "UserPromptSubmit": [
+      {
+        "matcher": "",
+        "hooks": [
+          {
+            "type": "command",
+            "command": "./skills/self-improvement/scripts/activator.sh"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## GitHub Copilot Setup
+
+Copilot doesn't support hooks directly. Instead, add guidance to `.github/copilot-instructions.md`:
+
+```markdown
+## Self-Improvement
+
+After completing tasks that involved:
+- Debugging non-obvious issues
+- Discovering workarounds
+- Learning project-specific patterns
+- Resolving unexpected errors
+
+Consider logging the learning to `.learnings/` using the format from the self-improvement skill.
+
+For high-value learnings that would benefit other sessions, consider skill extraction.
+```
+
+## Verification
+
+### Test Activator Hook
+
+1. Enable the hook configuration
+2. Start a new Claude Code session
+3. Send any prompt
+4. Verify you see `<self-improvement-reminder>` in the context
+
+### Test Error Detector Hook
+
+1. Enable PostToolUse hook for Bash
+2. Run a command that fails: `ls /nonexistent/path`
+3. Verify you see `<error-detected>` reminder
+
+### Dry Run Extract Script
+
+```bash
+./skills/self-improvement/scripts/extract-skill.sh test-skill --dry-run
+```
+
+Expected output shows the skill scaffold that would be created.
+
+## Troubleshooting
+
+### Hook Not Triggering
+
+1. **Check script permissions**: `chmod +x scripts/*.sh`
+2. **Verify path**: Use absolute paths or paths relative to project root
+3. **Check settings location**: Project vs user-level settings
+4. **Restart session**: Hooks are loaded at session start
+
+### Permission Denied
+
+```bash
+chmod +x ./skills/self-improvement/scripts/activator.sh
+chmod +x ./skills/self-improvement/scripts/error-detector.sh
+chmod +x ./skills/self-improvement/scripts/extract-skill.sh
+```
+
+### Script Not Found
+
+If using relative paths, ensure you're in the correct directory or use absolute paths:
+
+```json
+{
+  "command": "/absolute/path/to/skills/self-improvement/scripts/activator.sh"
+}
+```
+
+### Too Much Overhead
+
+If the activator feels intrusive:
+
+1. **Use minimal setup**: Only UserPromptSubmit, skip PostToolUse
+2. **Add matcher filter**: Only trigger for certain prompts:
+
+```json
+{
+  "matcher": "fix|debug|error|issue",
+  "hooks": [...]
+}
+```
+
+## Hook Output Budget
+
+The activator is designed to be lightweight:
+- **Target**: ~50-100 tokens per activation
+- **Content**: Structured reminder, not verbose instructions
+- **Format**: XML tags for easy parsing
+
+If you need to reduce overhead further, you can edit `activator.sh` to output less text.
+
+## Security Considerations
+
+- Hook scripts run with the same permissions as Claude Code
+- Scripts only output text; they don't modify files or run commands
+- Error detector reads `CLAUDE_TOOL_OUTPUT` environment variable
+- All scripts are opt-in (you must configure them explicitly)
+
+## Disabling Hooks
+
+To temporarily disable without removing configuration:
+
+1. **Comment out in settings**:
+```json
+{
+  "hooks": {
+    // "UserPromptSubmit": [...]
+  }
+}
+```
+
+2. **Or delete the settings file**: Hooks won't run without configuration
