## What it does

gsd-plugin, now named Buildomator, gives Claude Code a staged workflow for project work. It covers project setup, phase planning, execution, and verification through `/bm:` commands. Each step runs in a focused subcontext, keeping separate work from competing for the same conversation space.

The plugin includes 60+ slash commands, 21 agents, hooks, an MCP server for project state, and cross-session memory. It can resume work after `/compact`. Its bundled SDK exposes the `bm-sdk` command and the equivalent `gsd-sdk` alias.

A previously installed global SDK can take precedence over those bundled wrappers and cause parts of the workflow to be skipped. Check `which bm-sdk gsd-sdk` before installing. Installation happens from inside a Claude Code session.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install gsd-plugin@claude-community
```

## When to use it
- plan a project phase
- split a large codebase task into focused steps
- run a planned phase with agents
- verify completed project work
- resume project state across sessions

## Example prompts
- Start a new project with `/bm:new-project`.
- Plan the first project phase using `/bm:plan-phase`.
- Run the current phase, then check it with `/bm:execute-phase` and `/bm:verify-work`.

# Buildomator for Claude Code

**Plugin version:** `4.1.0`

**Buildomator** (formerly [gsd-plugin](https://github.com/jnuyens/gsd-plugin)) is a Claude Code plugin that plans, executes, and verifies your work. It asks you only about the real design and architecture decisions that need your judgment, then carries out the rest on its own. Each step runs in its own focused subcontext, so token use stays low even on long projects.

Buildomator is a performance-optimized evolution of GSD for Claude Code: it cuts per-turn token overhead by ~92%, keeps project state in an MCP-backed store, and auto-resumes across `/compact` so a compaction never loses your place.

## Installation

GSD Plugin installs *inside* a Claude Code session, not from your host shell. If you have never used Claude Code plugins before, follow these steps in order.

### No prerequisites

As of **v2.42.0** the plugin bundles its own copy of the GSD SDK at `sdk/dist/cli.js` and ships a `bin/bm-sdk` wrapper (plus a `bin/gsd-sdk` alias) that Claude Code automatically puts on `PATH` for plugin Bash calls. `bm-sdk` is the primary command name; `gsd-sdk` keeps working as a fully equivalent alias, and the retirement once planned for v5.0 is deferred, so both continue to work. You no longer need to `npm install -g get-shit-done-cc` (or its successor `get-shit-done-redux`). Closes [#4](https://github.com/buildomator/buildomator/issues/4).

### Pre-install: remove any pre-v2.42.0 global SDK install

If you previously installed `get-shit-done-cc` / `get-shit-done-redux` or `@gsd-build/sdk` / `@gsd-redux/sdk` via `npm -g` (or `npx`), the global binary at `/opt/homebrew/bin/gsd-sdk` (Apple Silicon) or `/usr/local/bin/gsd-sdk` (Intel macOS / Linux) takes precedence in `$PATH` over the plugin's bundled wrapper. The npm package now maps both `bm-sdk` and `gsd-sdk` to the same CLI, so a shadowing global can hijack either name. The global SDK does NOT honor `CLAUDE_PLUGIN_ROOT`, so every plugin workflow that calls bare `bm-sdk` (or `gsd-sdk`) for init queries, agent-skill lookups, or config reads reports `agents_installed: false`, and skills like `/bm:new-project` silently degrade by skipping the parallel research path. The plugin's wrapper-env-export patch only fires when the wrapper itself is invoked, so a shadowing global bypasses it.

Check whether you have a shadowing install:

```bash
which bm-sdk gsd-sdk
```

If either name resolves to anything OTHER than a path under `~/.claude/plugins/cache/` (typical bad outputs are `/opt/homebrew/bin/gsd-sdk` or `/usr/local/bin/gsd-sdk`), uninstall it from your host shell before going further:

```bash
npm uninstall -g @gsd-build/sdk
npm uninstall -g get-shit-done-cc
npm uninstall -g @gsd-redux/sdk
npm uninstall -g @opengsd/get-shit-done-redux
npm uninstall -g get-shit-done-redux   # if you tried the unscoped name (404s on npm; v2.43.x docs incorrectly referenced this form, fixed in v2.44.6)
```

Re-run `which bm-sdk gsd-sdk`. The expected post-uninstall output is either a path under `~/.claude/plugins/cache/` (after the plugin is installed in Step 3) or not found (before installation). Both are correct.

If you skip this step and install the plugin anyway, v2.43.1+ ships a `gsd-shadowing-sdk-detector` SessionStart hook that will detect the conflict at the start of every Claude Code session and emit a one-time advisory pointing back to this section.

### Step 1: Trust GitHub's SSH host key (first time only on a new machine)

`/plugin marketplace add` clones over SSH. On a fresh machine GitHub's host key is unknown, which makes the non-interactive `git clone` Claude Code runs fail silently. Prime `known_hosts` once from your host shell:

```bash
ssh -T git@github.com
```
