Looper-Go Development

Overview

Looper-Go is a Go implementation of the autonomous AI loop runner. This skill covers common development workflows.

Common Commands

Build

# Build binary
go build ./cmd/looper

# Build to custom location
go build -o ~/bin/looper ./cmd/looper

# Build for multiple platforms
go build -o bin/looper-linux ./cmd/looper
GOOS=darwin go build -o bin/looper-macos ./cmd/looper
GOOS=windows go build -o bin/looper.exe ./cmd/looper

Test

# Run all tests
go test ./...

# Run with coverage
go test -cover ./...

# Run specific package
go test ./internal/loop

# Verbose output
go test -v ./internal/loop

# Run make test (includes smoke tests)
make test

Run

# Default run (uses to-do.json in current dir)
looper run

# Specify max iterations
LOOPER_MAX_ITERATIONS=5 looper run

# Run with specific task file
looper --task-file path/to/tasks.json run

# View logs
looper tail

# List tasks
looper ls

# Show config
looper config

# Check dependencies
looper doctor

Debug

# Enable debug logging
LOOPER_DEBUG=1 looper run

# View JSONL logs
looper tail

# View specific run
looper tail --run <run-id>

# Validate task file
looper validate

# Format task file
looper fmt

Development Workflow

1. Make Changes

Edit code in internal/ or cmd/ as needed.

2. Test Changes

# Run unit tests
go test ./...

# Run smoke tests
make test

# Run live test
~/.codex/skills/looper-live-test/scripts/run-live-test.sh

3. Commit Changes

# Check status
git status

# Run pre-commit hooks (if installed)
pre-commit run --all-files

# Commit
git commit -m "feat: description"

4. Build and Install

# Build
go build ./cmd/looper

# Install to PATH
go install ./cmd/looper

Configuration

Config File Locations (priority order)

1. .looper/config.json - Project-specific
2. ~/.config/looper/config.json - User config
3. Environment variables (LOOPER_*)
4. CLI flags

Example Config

{
  "max_iterations": 100,
  "agent": {
    "type": "claude",
    "model": "claude-3-5-sonnet-20241022"
  },
  "paths": {
    "log_dir": "./looper-logs"
  }
}

Key Environment Variables

Troubleshooting

Build Fails

# Clean and rebuild
go clean -cache
go mod tidy
go build ./cmd/looper

Tests Fail

# Run verbose to see details
go test -v ./...

# Check specific package
go test -v ./internal/loop

Agent Not Found

# Check config
looper config

# Verify agent binary exists
which codex
which claude

# Check in config
cat .looper/config.json | jq '.agent'

Adding New Features

1. Add Internal Package

mkdir internal/feature
# Create feature.go

2. Add Tests

# Create feature_test.go
go test ./internal/feature

3. Wire Into Loop

Edit internal/loop/loop.go to use new feature.

4. Update Documentation

• Edit ARCHITECTURE.md if structural change
• Edit README.md if user-facing
• Add godoc comments

Release Process

Use the release-runbook skill:

~/.codex/skills/release-runbook/scripts/release.sh --version 1.2.3 --test-cmd "make test"

Code Style

• Standard Go formatting (gofmt)
• Conventional commits for commit messages
• Add tests for new functionality
• Update documentation

Resources

• ARCHITECTURE.md - Full architecture documentation
• README.md - User documentation
• CONTRIBUTING.md - Contribution guidelines
• AI_POLICY.md - AI contribution policy
