## What it does

developer-essentials by Seth Hobson packs the routine parts of coding into one plugin: Git workflows, SQL optimization, error handling, code review, E2E testing, authentication, debugging and monorepo management. It installs into Claude from the `wshobson/agents` marketplace.

Two commands get it running: add the marketplace, then install the plugin. Once it is in, the skills are available to the agent during a session — ask it to look at a slow query or walk a diff before you merge.

The plugin ships under MIT, so forking and trimming it for your own repo is fair game. The author lists Claude, Codex and Cursor as supported, which is worth checking against your own setup before you rely on it.

## Install

### Claude Code (native platform)

**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 developer-essentials@claude-code-workflows
```

## When to use it
- find out why a SQL query is slow and rewrite it
- review a diff before merging
- set up an end-to-end test for a new flow
- debug a failure that only shows up sometimes
- sort tasks across packages in a monorepo

## Example prompts
- look at this SQL query and suggest how to speed it up
- review this diff before I merge
- help me debug this failing test in the module
