Using Shipyard with Codex

Shipyard also installs under Codex CLI (0.124.0+) on a
best-effort, not-parity basis — all skills run natively; the multi-agent workflows

instead of via a session hook.

Quick Start

Once installed, navigate to any project directory and run:

spec-kit Integration

Shipyard integrates with spec-kit (GitHub's Spec-Driven Development toolkit), letting you use spec-kit's structured specification workflow as a higher-quality alternative to /shipyard:brainstorm.

spec-kit produces a rich set of artifacts in specs/[###-feature]/:

The /shipyard:plan command automatically detects these staged artifacts:
- Skips the researcher agent when RESEARCH.md already exists
- Seeds the architect with SPECKIT-TASKS.md to generate accurate wave/plan decomposition with less hallucination

Workflow

/shipyard:import-spec also handles:
- Auto-discovery: if no argument is given, lists available specs/ directories
- [NEEDS CLARIFICATION] markers: surfaced as an Open Questions section in…
