# Entry Examples
Concrete examples of well-formatted entries with all fields.
## Learning: Correction
```markdown
## [LRN-20250115-001] correction
**Logged**: 2025-01-15T10:30:00Z
**Priority**: high
**Status**: pending
**Area**: tests
### Summary
Incorrectly assumed pytest fixtures are scoped to function by default
### Details
When writing test fixtures, I assumed all fixtures were function-scoped.
User corrected that while function scope is the default, the codebase
convention uses module-scoped fixtures for database connections to
improve test performance.
### Suggested Action
When creating fixtures that involve expensive setup (DB, network),
check existing fixtures for scope patterns before defaulting to function scope.

## Learning: Knowledge Gap (Resolved)

**Area**: config
### Summary
Project uses pnpm not npm for package management
### Details
Attempted to run `npm install` but project uses pnpm workspaces.
Lock file is `pnpm-lock.yaml`, not `package-lock.json`.
### Suggested Action
Check for `pnpm-lock.yaml` or `pnpm-workspace.yaml` before assuming npm.
Use `pnpm install` for this project.

**Promoted**: CLAUDE.md
**Area**: backend
### Summary
API responses must include correlation ID from request headers
### Details
All API responses should echo back the X-Correlation-ID header from
the request. This is required for distributed tracing. Responses
without this header break the observability pipeline.
### Suggested Action
Always include correlation ID passthrough in API handlers.

### Summary
Must regenerate API client after OpenAPI spec changes
### Details
When modifying API endpoints, the TypeScript client must be regenerated.
Forgetting this causes type mismatches that only appear at runtime.
The generate script also runs validation.
### Suggested Action
Add to agent workflow: after any API changes, run `pnpm run generate:api`.

### Summary
Docker build fails on Apple Silicon due to platform mismatch
### Details
When building Docker images on M1/M2 Macs, the build fails because
the base image doesn't have an ARM64 variant. This is a common issue
that affects many developers.
### Suggested Action
Add `--platform linux/amd64` to docker build command, or use
`FROM --platform=linux/amd64` in Dockerfile.
### Metadata

# Docker M1 Fixes
Solutions for Docker build issues on Apple Silicon Macs.
## Quick Reference
| Error | Fix |
|-------|-----|
| `no match for platform linux/arm64` | Add `--platform linux/amd64` to build |
| Image runs but crashes | Use emulation or find ARM-compatible base |
## The Problem
Many Docker base images don't have ARM64 variants. When building on
Apple Silicon (M1/M2/M3), Docker attempts to pull ARM64 images by
default, causing platform mismatch errors.
## Solutions
### Option 1: Build Flag (Recommended)
Add platform flag to your build command:
\`\`\`bash
docker build --platform linux/amd64 -t myapp .
\`\`\`
### Option 2: Dockerfile Modification
Specify platform in the FROM instruction:
\`\`\`dockerfile
FROM --platform=linux/amd64 python:3.11-slim
\`\`\`
### Option 3: Docker Compose
Add platform to your service:
\`\`\`yaml
services:
app:
platform: linux/amd64
build: .
\`\`\`
## Trade-offs
| Approach | Pros | Cons |
|----------|------|------|
| Build flag | No file changes | Must remember flag |
| Dockerfile | Explicit, versioned | Affects all builds |
| Compose | Convenient for dev | Requires compose |
## Performance Note
Running AMD64 images on ARM64 uses Rosetta 2 emulation. This works
for development but may be slower. For production, find ARM-native
alternatives when possible.

# 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
