Install

Feature Forge runs on Claude Code (the first-class surface) and on other coding agents through generated adapter bundles. Pick the path that matches your agent, then install the Stage-5 loop runner.

Claude Code (preferred)

# Register the marketplace (one-time)
/plugin marketplace add garygentry/feature-forge

# Install the plugin
/plugin install feature-forge@feature-forge

Skills are then available as slash commands — e.g. /feature-forge:forge-init or /feature-forge:forge for a status check. Claude installs under ~/.claude.

Other agents (Codex, Copilot, Cursor, Gemini)

The universal installer copies the generated adapter bundle into every coding agent it detects on your machine:

npx @garygentry/feature-forge install                    # all detected agents
npx @garygentry/feature-forge install -a codex           # a single agent
npx @garygentry/feature-forge install --dry-run --json   # preview the plan, change nothing

The --dry-run --json plan reports the exact install destination per agent. See Cross-agent usage for per-agent notes and the agent-selection rules used by the loop.

Install the loop runner (for Stage 5)

Stage 5 runs an autonomous coding loop. The default runner is rauf, published to npm as @garygentry/rauf. Install the rauf CLI with npx:

npx @garygentry/rauf --help          # or install globally: npm i -g @garygentry/rauf

Prefer a standalone binary? Use the install script instead:

curl -fsSL https://raw.githubusercontent.com/garygentry/rauf/main/scripts/install-binary.sh | bash

Then, inside each project where you’ll run the loop, set up rauf’s per-project files:

rauf install .

You only need the runner before you reach Stage 5 — you can install the plugin and start writing a PRD right away.

Verify the install

npx @garygentry/feature-forge list        # per-agent installed / up-to-date status

In Claude Code, type /feature-forge:forge-init and confirm the skill resolves.
