humanfile: Instructions file for Codex

AGENTS.md

humanfile AGENTS.md is an instructions file for Codex, OpenCode from zhangyu94/humanfile. It costs 721 tokens per session, scanned A, original, MIT.

A repository guide for coding agents that explains the project structure, important documents, architecture, and editing rules. It also describes humanfile, a tool where file ownership is declared in .human files.

In plain words
What is it for?
Use it to orient an agent in the humanfile repository, find design documents and implementation plans, and follow its coding and documentation conventions.
Why use it?
It gives an agent a map of the codebase and tells it to get approval before changing files owned by someone else. This helps prevent edits that ignore project conventions or ownership boundaries.

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

This is zhangyu94/humanfile's own configuration. It tells Codex and OpenCode how to work on humanfile 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 humanfile configures →

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

humanfile 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.

AGENTS.md

This file is the entry point for AI coding agents working in this repository. It serves as a map — not an encyclopedia. Follow the pointers below to find deeper context.

Repository Overview

humanfile lets developers declare which files they take responsibility for via .human files. Agents learn to obtain explicit approval before editing, treat these files as source of truth, and respect ownership boundaries. The project ships a core library + CLI, a GitHub Action, and agent guidance for multiple platforms.

Architecture

See ARCHITECTURE.md for the package layout, dependency graph, and module responsibilities.

Documentation Map

All long-form documentation lives in docs/:

Path Contents
docs/design/ Design decisions, core beliefs
docs/plans/active/ Current implementation plans
docs/plans/completed/ Archived completed plans
docs/specs/ Product specifications and requirements
docs/references/ External reference material
docs/RELEASE.md Internal release/shipping runbook
docs/DESIGN.md High-level design philosophy
docs/PLANS.md Plans index and status

Placement rule:

  • docs/references/ is only for information derived from outside this repository.
  • Internal operational guides (for example release/shipping steps) belong in docs/ (for example docs/RELEASE.md).

Key Conventions

  • Language: TypeScript (ESM-first, dual CJS build for the core library)
  • Package manager: pnpm with workspaces
  • Monorepo layout: packages/core (lib + CLI + configs), packages/action
  • Tests: Vitest — run pnpm test from root or any package
  • Build: tsdown — run pnpm build from root or any package
  • Cross-platform: The implementation is expected to work and to be tested on MacOS/Linux/Windows

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.
