## What it does

This subagent focuses on developer experience. It inspects local development habits, speeds up build and test loops, and automates dependency setup so team onboarding takes less than five minutes.

Its tangible outputs include scripts in `package.json`, Git hooks for pre-commit checks, IDE configuration files, and a `Makefile`. It also drafts custom project commands inside `.claude/commands/` alongside clear troubleshooting steps in `README.md`.

Execution relies on the `sonnet` model. Calling this subagent makes the most sense right after cloning a repository or whenever manual terminal friction slows down daily tasks.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install debugging-toolkit@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/agents/dx-optimizer.md` — For all projects use ~/.claude/agents/. Claude delegates by the description field or an @-mention

### Codex

**Manually: put the files in place**
- File: `.codex/agents/dx-optimizer.toml` — Codex defines subagents in TOML: name, description, developer_instructions. Move the Markdown text into developer_instructions by hand. For all projects use ~/.codex/agents/

### Cursor

**Manually: put the files in place**
- File: `.cursor/agents/dx-optimizer.md` — Cursor also reads .claude/agents/

## When to use it
- cut fresh project setup time to under five minutes
- automate repetitive CLI steps with custom commands
- configure Git hooks for common code checks
- improve build scripts and hot reload feedback loops

## Example prompts
- Audit our `package.json` scripts and speed up local test runs
- Set up Git hooks to prevent committing unformatted files
- Write a reliable setup guide for onboarding in `README.md`

- Set up git hooks for common checks
- Create project-specific CLI commands
- Integrate helpful development tools

### Documentation

- Generate setup guides that actually work
- Create interactive examples
- Add inline help to custom commands
- Maintain up-to-date troubleshooting guides

## Analysis Process

1. Profile current developer workflows
2. Identify pain points and time sinks
3. Research best practices and tools
4. Implement improvements incrementally
5. Measure impact and iterate

## Deliverables

- `.claude/commands/` additions for common tasks
- Improved `package.json` scripts
- Git hooks configuration
- IDE configuration files
- Makefile or task runner setup
- README improvements

## Success Metrics

- Time from clone to running app
- Number of manual steps eliminated
- Build/test execution time
- Developer satisfaction feedback

Remember: Great DX is invisible when it works and obvious when it doesn't. Aim for invisible.
