Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is mattzcarey/shippie's own configuration. It tells Codex and OpenCode how to work on shippie 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 shippie 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 A, and why

shippie 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 9d 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.

Repository Guidelines

Shippie is a prebuilt code-review agent built on flue (which runs the agent loop on "pi"). It ships as a flue project and as a GitHub Action, and runs anywhere flue deploys (Node, Cloudflare, GitHub Actions, GitLab CI).

Project Structure

  • flue.config.ts — defineConfig({ target: 'node' }).
  • src/agents/reviewer.ts — the review agent (createAgent): model, local() sandbox, instructions, and the suggest_change tool.
  • src/workflows/review.ts — the one-shot review workflow (run({ init, payload, env })); also exports route so the built server can serve POST /workflows/review.
  • src/tools/suggest-change.ts — defineTool for inline review comments.
  • src/review/ — config.ts (resolve config from payload/env), diff.ts (git diff + parsing), instructions.ts (review prompt + AGENTS.md/CLAUDE.md injection), context.ts (prompt builder), constants.ts, prompt/fileInfo.ts, utils/filterFiles.ts.
  • tests/ — vitest specs (*.test.ts), mirroring the src/ layout (kept out of src/ so the package code stays clean).
  • src/github/reporter.ts — posts inline comments + summary to GitHub (Octokit) or to a local file.
  • src/mcp/connect.ts — connects remote MCP servers from config.
  • src/common/ — shared types.ts and formatting/summary.ts.
  • action.yml — composite GitHub Action. docs/ — user docs (docs/flue-migration.md is the refactor log).

Build, Test, and Development Commands

  • Install: npm install (Node >= 22.19 required).
  • Lint + format: npm run check (oxlint + oxfmt). Auto-fix: npm run check:fix.
  • Type-check: npm run check:types (tsc --noEmit).
  • Build: npm run build (flue build --target node → dist/server.mjs).
  • Run a review locally: npm run review (flue run review --target node); reviews staged changes and writes to .shippie/review/. Pass --payload '{"platform":"local"}' explicitly if needed.
  • Run the built server: npm start (node dist/server.mjs), then POST /workflows/review?wait=result.
  • Tests: npm test (vitest).

Changes

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.
