description	Build a specific feature or improvement using Factory's multi-agent system. Runs the Factory CEO in focus mode to study the codebase, generate a hypothesis, build the change, review it, and evaluate the result. Use when the user says 'implement X', 'build X', 'add X feature', or wants autonomous multi-agent development on a specific task.

/factory:implement

Build a specific feature or improvement using the Factory's multi-agent system.

The user wants to build: $ARGUMENTS

Prerequisites

The factory CLI must be installed. Check and install from the plugin's bundled source:

command -v factory >/dev/null 2>&1 || uv tool install "${CLAUDE_PLUGIN_ROOT}"

Execution

The project must have .factory/ initialized (run factory ceo "$(pwd)" or /factory:study first). Focus mode requires improve mode — it will error if the project hasn't been set up yet.

Run the Factory CEO in focus mode on the current project:

factory ceo "$(pwd)" --focus "$ARGUMENTS"

This will:

1. Study the codebase and generate observations
2. Strategize a single targeted hypothesis for "$ARGUMENTS"
3. Build the change on a feature branch with a PR
4. Review the change against guard rules and scope constraints
5. Evaluate before/after scores to verify improvement
6. Keep or revert based on eval results and precheck gates
7. Archive learnings for future cycles

If the CLI is not available

If factory cannot be installed (e.g. no uv available), tell the user:

To use /factory:implement, install the Factory CLI:

  uv tool install /path/to/remote-factory
  # or from git
  uv tool install git+https://github.com/akashgit/remote-factory

Then re-run this command.
