Instructions file for CodexOpenCode

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

This is bradwmorris/ra-h_os's own configuration. It tells Codex and OpenCode how to work on ra-h_os 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 ra-h_os 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

ra-h_os 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.

RA-OS Agent Workflow (Open Source)

This file is the source of truth for AI agents and contributors working in this repository.

Scope

  • This workflow applies to ra-h_os only.
  • Do not require private-repo docs, handoffs, or backlog files to complete work here.

Working Rules

  1. Start from main and create a branch:
    • feat/<short-name>
    • fix/<short-name>
    • docs/<short-name>
  2. Keep changes small and reviewable.
  3. If behavior changes, update docs in the same PR.
  4. Do not commit directly to main.

Standard Dev Loop

  1. Reproduce/define the problem.
  2. Implement the minimal correct change.
  3. Run local checks.
  4. Update docs and screenshots if needed.
  5. Open PR with clear summary and test notes.

Required Checks

npm run type-check
npm run lint
npm run build

Docs Map

  • README.md - product overview + quick start
  • docs/README.md - docs index
  • docs/4_tools-and-guides.md - MCP tools + skills surface
  • docs/6_ui.md - UI behavior
  • docs/8_mcp.md - MCP setup, troubleshooting, and memory-file guidance
  • docs/development/process.md - contributor process
  • docs/development/docs-process.md - docs maintenance process

Upstream Relationship

  • ra-h_os accepts direct contributions.
  • Maintainers may sync relevant changes between public and private repos.
  • Public contributions should remain attributable and not be overwritten.
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.
