agentpack: Instructions file for Codex

AGENTS.md

agentpack AGENTS.md is an instructions file for Codex, OpenCode from liqiongyu/agentpack. It costs 1,011 tokens per session, scanned A, original, MIT.

Repository instructions for Agentpack, a Rust command-line tool that manages coding-agent assets and workflows.

In plain words
What is it for?
Checking when to read OpenSpec proposals, understanding the repository layout, and following its build and test process.
Why use it?
They give an agent the project rules, important files, specifications, and commands needed to work safely in that codebase.

Instructions file for CodexOpenCode

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

This is liqiongyu/agentpack's own configuration. It tells Codex and OpenCode how to work on agentpack 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 agentpack 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

agentpack 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 1mo 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.

OpenSpec Instructions

These instructions are for AI assistants working in this project.

Always open @/openspec/AGENTS.md when the request:

  • Mentions planning or proposals (words like proposal, spec, change, plan)
  • Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
  • Sounds ambiguous and you need the authoritative spec before coding

Use @/openspec/AGENTS.md to learn:

  • How to create and apply change proposals
  • Spec format and conventions
  • Project structure and guidelines

Keep this managed block so 'openspec update' can refresh the instructions.

Repository Guidelines

Project Structure & Module Organization

  • src/: Rust CLI (agentpack).
  • templates/: embedded operator assets (Codex skill + Claude commands) used by agentpack bootstrap.
  • tests/: unit tests + golden snapshots (tests/golden/).
  • docs/: product/design docs (docs/PRD.md, docs/ARCHITECTURE.md, docs/SPEC.md, docs/BACKLOG.md).
  • openspec/: proposal-driven changes + archived changes under openspec/changes/archive/.
  • .github/: CI and GitHub templates.

Specs & Contracts

  • docs/SPEC.md is the authoritative, implementation-level contract (CLI behavior, --json envelopes, file formats).
  • docs/JSON_API.md and docs/ERROR_CODES.md define the stable --json envelope rules and error codes for automation.
  • openspec/specs/ is the OpenSpec “requirements slice”; changes go through openspec/changes/<change-id>/... and MUST stay consistent with docs/SPEC.md.
  • If you change stable output (especially --json), update docs/SPEC.md, OpenSpec deltas, and relevant snapshots under tests/golden/.
    • If you add a new mutating command, update src/cli/util.rs (MUTATING_COMMAND_IDS), agentpack help --json, and guardrails tests (tests/cli_guardrails.rs).

Build, Test, and Development Commands

  • just check: run the standard local/CI checks (preferred).
  • cargo fmt --all -- --check: formatting (required).
  • cargo clippy --all-targets --all-features -- -D warnings: lint (required).
  • cargo test --all --locked: tests (required in CI).
  • pre-commit install: install git hooks (one-time).
  • pre-commit run -a: run repo hooks locally.
  • agentpack completions <shell>: generate shell completions.
  • openspec validate --all --strict --no-interactive: validate OpenSpec specs in CI-friendly 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.
