ship-it: Instructions file for Claude Code

AGENTS.md

ship-it AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from samsantosb/ship-it. It costs 973 tokens per session, scanned A, original, MIT.

A guide for running a development pipeline with any coding agent, even when the agent does not support a built-in skill system.

In plain words
What is it for?
Use it to run skills manually, connect the pipeline repository to a separate target repository, and follow shared guardrails across coding tools.
Why use it?
It explains how to follow plain Markdown playbooks and map common tools such as Git and GitHub or GitLab commands, avoiding dependence on one agent platform.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: ${CLAUDE_PLUGIN_ROOT} variable, but also the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions CLAUDE.md; names the AskUserQuestion tool.

This is samsantosb/ship-it's own configuration. It tells Claude Code, Codex and OpenCode how to work on ship-it 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 ship-it configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

ship-it AGENTS.md 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 2mo 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.

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — running this pipeline on any agent

This pipeline is harness-agnostic by design: the skills are plain-markdown playbooks, the contracts are plain files, and the tools are git, gh/glab and file edits. Any capable coding agent — Kiro, opencode, OpenAI Codex, Gemini CLI, Cursor, Zed, aider, Claude Code, an OSS model on any harness — can run it by following this page. (The .claude-plugin/ manifests exist only for harnesses with native plugin support; nothing else depends on them.)

How to run a skill without a skill system

  1. Open skills/<name>/SKILL.md and follow it top to bottom as your instructions for the task. The user's argument (a card path, a PR number, an idea) is the skill's input. Ignore the YAML frontmatter — it is skill-system metadata for harnesses with native skill support (disable-model-invocation included).
  2. Resolve ${CLAUDE_PLUGIN_ROOT} to this repository's root: ${CLAUDE_PLUGIN_ROOT}/shared/guardrails.md means shared/guardrails.md here. "Load before acting" means read those files before doing anything else.
  3. When a skill hands off to another (/watch-pr <PR>, /create-tasks <doc>), open that skill's SKILL.md and continue with the given argument.

Tool equivalences

The playbooks name a few tools by their Claude Code names (the reference harness for tool naming); substitute your harness's equivalent:

In the playbooks Use instead
AskUserQuestion (batched, up to 4 questions, options with "(Recommended)") Ask in chat: numbered options, recommended option first, one message for the whole batch
Grep / Glob / Read / Write tools Your search/read/write equivalents (rg, your editor tooling)
Skill chaining / slash commands Open the referenced SKILL.md and keep going
Session scratchpad (watch-pr state file) Any writable temp directory outside the target repo
Resume commands in notifications (/do-task tasks/TASK-007.md) Write the invocation your harness understands — the human must be able to paste it
"User memory" (resolution step 3; personal facts like a Slack handle) Your harness's memory store if it has one; otherwise skip that step and ask — personal facts never go into the repo either way
MCP/connector registration (claude mcp add …, Connectors menu) Your harness's own MCP/connector mechanism; no MCP support → prefer the CLI paths (gh, glab) and local Markdown mode

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.
