shipyard-codex-orchestration

shipyard-codex-orchestration is a skill for Claude Code from lgbarn/shipyard. It costs 104 tokens per session (708 once invoked), scanned A, original, MIT.

Guidelines for running Shipyard’s multi-step coding workflows in Codex. Shipyard is a workflow system for tasks such as building, auditing, planning, reviewing, researching, and mapping.

In plain words
What is it for?
Use it to run Shipyard workflows as sequential roles, including builder, reviewer, auditor, architect, verifier, researcher, and mapper.
Why use it?
It explains how to preserve review and verification stages when separate parallel agents are unavailable, reducing the risk of skipping important checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shipyard-codex-orchestration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shipyard orchestration under Codex

Shipyard was built for Claude Code, where workflows dispatch fresh subagents in parallel (builder, reviewer, auditor, architect, verifier, researcher, mapper, …) via the Task tool. Codex has no equivalent — it runs in a single context.

So under Codex, Shipyard workflows run as inline sequential personas: instead of dispatching a separate agent, you adopt each role yourself, one after another, in this same conversation.

Honest degradation — what you lose

  • No parallelism. Roles run one at a time, so multi-agent phases are slower.
  • No context isolation. In Claude Code a fresh reviewer can't be biased by the builder's reasoning. Here the same context does both, so a review is less independent. Compensate by being deliberately skeptical when you switch into a review/verify role — re-read the actual artifact, don't trust your own prior step.

What you keep: the discipline — the review and verify gates still run, just sequentially.

The inline-sequential pattern

When a workflow calls for "dispatch the X agent", instead:

  1. State which role you're entering ("Now acting as the reviewer…").
  2. Adopt that role's mandate fully — including its MUST-NOT constraints (a reviewer makes no code edits; a mapper only documents).
  3. Produce the role's deliverable.
  4. Exit the role and continue the workflow.

Routing — which skill for which intent

Intent Skill / behavior
Implement a plan shipyard-executing-plans skill, run builder→reviewer→verifier inline
Security/compliance audit security-audit skill, adopting the auditor mandate
Create a plan shipyard-writing-plans skill (+ shipyard-brainstorming first)
Code review after a build shipyard-review skill
Domain/technology research shipyard-research skill
Map/onboard a codebase shipyard-map skill
Ship/release a completed phase shipyard-ship skill
TDD a feature shipyard-tdd skill
Debug a failure shipyard-debugging skill

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
