shipit: Skill for Claude Code

.claude/skills/dogfooding-shipit/SKILL.md

dogfooding-shipit is a skill for Claude Code from nikzlabs/shipit. It costs 81 tokens per session (2,797 once invoked), scanned C, original, Apache-2.0.

A guide to running ShipIt inside another ShipIt instance for development and testing. It explains the local Compose preview, setup limits, credentials, test data, and HTTP control.

In plain words
What is it for?
Use it when starting or debugging the inner ShipIt interface, preparing a test repository, setting credentials, or controlling the inner instance through its HTTP API.
Why use it?
It helps developers understand the special setup of this nested test environment and avoid treating its intentional limitations as bugs.

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 C, and why

dogfooding-shipit scanned grade C with 2 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 11d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dogfooding ShipIt in ShipIt

Opening the ShipIt repo in production ShipIt surfaces the dev Compose service as a manual preview — heavy enough (a whole second orchestrator, plus a Dockerfile.dogfood build) that it starts on demand rather than every boot. It shares the agent container's /workspace/node_modules (populated by agent.install at session boot) and runs Vite's dev server on the exposed port 3000, proxying /api, /ws, and /preview to the inner orchestrator on internal port 4000. It does not run its own npm install or a production vite build — the Compose file explains why that would be redundant and unsafe.

Start it with shipit service start dev. A first start may take minutes; a start that times out is still running — re-check with shipit service list.

Local mode is a real exception to "ShipIt always runs in Docker"

The inner orchestrator runs with RUNTIME_MODE=local, which skips Docker entirely: no inner containers, no inner Compose, and inner agents spawn in-process via claude-adapter / codex-adapter rather than in a session worker container.

That makes several things degrade, by design — do not treat them as bugs:

  • No inner terminal
  • No inner file watcher
  • No inner preview

Full design: docs/118-shipit-ui-local.

Credentials — set them once, outside

The dev service's credentials are user-supplied secrets, set once in the outer Settings → Secrets (docs/184-remove-platform-secret-forwarding). Platform secret forwarding was deliberately removed, so nothing is inherited.

GITHUB_TOKEN plus any service credential you want to exercise is the set. The x-shipit-secrets block in docker-compose.yml declares every storageEnv name the model catalogue knows — ANTHROPIC_AUTH_TOKEN, ANTHROPIC_API_KEY, OPENAI_API_KEY, DEEPSEEK_API_KEY, ZAI_CODING_PLAN_KEY, ZAI_API_KEY, OPENROUTER_API_KEY, VERCEL_AI_GATEWAY_API_KEY — so a key set once out there appears in every dogfood session without a visit to inner Settings (docs/131 req 11).

What this file has done since we first saw it

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.

dogfooding-shipit is a skill published in the GitHub repository nikzlabs/shipit (7 stars, last pushed today), licensed Apache-2.0. It adds 81 tokens to every session and 2,797 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
