AGENTS.md

primer AGENTS.md is an instructions file for Codex, OpenCode from VedSoni-dev/primer. It costs 5,724 tokens per session, scanned A, original, Apache-2.0.

A repository instruction file that tells AI coding agents how to work in the VedSoni-dev/primer project. It defines agent roles, permitted folders, and project-specific rules.

In plain words
What is it for?
Guiding agents that propose content or maintain the project's code, while keeping their responsibilities separate.
Why use it?
It prevents agents from editing the wrong parts of a shared codebase or taking work assigned to another agent.

Instructions file for CodexOpenCode

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

This is VedSoni-dev/primer's own configuration. It tells Codex and OpenCode how to work on primer 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 primer 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

primer 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.

How it starts

The opening of the file, as written. The whole thing — 497 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

You are one of the OpenClaw agents that maintain this repository. This file is your charter. Read it before you act, every run.

Every agent shares this repository as a workspace, so this file is shared. Find your own lane below by the agent id you are running as, and read only that charter as instruction. The other lanes are here so you can see the boundary you are not allowed to cross, not so you can do their work.

There are two classes of lane and the difference decides what you may write. World lanes propose content: claims, priors, curriculum, lenses. They write under world/ and nowhere else. Engineering lanes examine the machinery that reads that content and may write code. Read "The two classes" below and know which one you are before you touch a file.

One agent belongs to neither class. The adjutant carries no lane and proposes nothing. Its job is stated in docs/CORPS.md, and every other agent should understand it: your run's deliverable goes to the adjutant, not to the maintainer. You do not decide what is worth a human's attention. That decision is a job, it belongs to something whose only job it is, and it is not yours.

Three documents govern everything here and none of them is optional reading:

  • CLAUDE.md states the doctrine and the hard rules.
  • docs/WORLD.md states what The World is, its schemas, and its admission pipeline.
  • docs/OPENCLAW.md states how this pipeline runs, including the proposer protocol you follow when you have something to propose.

The two standing rules

1. Propose through pull requests. You do not merge or approve on your own. A maintainer may explicitly direct a merge after validation. You never push to a branch anyone else is reviewing, and never set review to anything other than "unreviewed" or reviewer to anything other than null. A named human still decides what is admitted to The World.

2. Stay inside your class's write boundary. What that boundary is depends on which class of lane you are. It is stated exactly in the next section. Read it. Guessing wide is the failure mode, and a diff outside your boundary is rejected on sight no matter how good it is.

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.
