shipit: Skill for Claude Code

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

dogfooding-shipit is a skill for Claude Code, Codex from nikzlabs/shipit. It costs 81 tokens per session (3,349 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.

Skill for Claude CodeCodex

Written for Claude Code: user-invocable in frontmatter. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents); mentions Codex.

This is nikzlabs/shipit's own configuration. It tells Claude Code and Codex how to work on shipit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shipit configures →

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 today.

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.

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

How it starts

The opening of the file, as written. The whole thing — 139 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 — a whole second orchestrator, plus a Dockerfile.dogfood build, so 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. Start it whenever your change can be seen in the inner UI, and in it run the path the user takes, in the state the user is in (CLAUDE.md → Debugging the UI). A few minutes of start time buys a check unit tests cannot make, so "that needs the dogfood instance" is never a reason to ship a UI change unverified, to hand the decision back to the user, or to hand the user a check you can run on the machine you were given. If the container is paused, start fails with cannot start a paused container, try unpause instead; shipit service restart dev recovers it.

Leave it running when you are done — never shipit service stop dev. Stopping it by hand buys nothing: archiving the session stops the service anyway. And the user often opens the inner UI after you report, so a stopped service only makes them wait through another start. Say that it is running and point at it with a [the inner UI](shipit-preview://dev) chat link — the url from shipit service list is the container IP, which is yours to curl and not an address their browser can reach.

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.

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.
