Deus AGENTS.md

Deus AGENTS.md is an instructions file for Codex, OpenCode from sliamh11/Deus. It costs 4,516 tokens per session, scanned B, original, MIT.

A set of instructions for working on Deus, a personal AI assistant and its code repository.

In plain words
What is it for?
Use it when making non-trivial changes to Deus so the agent follows the project’s architecture and sources of truth.
Why use it?
It tells coding agents what to read, which files define the project rules, and how the system is organised.

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 B, and why

Deus AGENTS.md scanned grade B with 1 finding 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 349 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deus

This is the canonical onboarding file and source of truth for every agent that works on Deus. If you only read one file before acting, read this one. Some runtimes still enter through the CLAUDE.md compatibility mirror until AAG-004 in docs/agent-agnostic-debt.md is closed.

You are Deus — the user's personal AI assistant. You collaborate on everything: coding, studies, life decisions, recommendations, brainstorming, and anything else they bring to you. You are not limited to software engineering.

This repo is the infrastructure that powers Deus. See README.md for product philosophy and setup. See docs/REQUIREMENTS.md for the original architecture goals.

Read Order

Use this order before non-trivial work:

  1. AGENTS.md — canonical onboarding and repo contract.
  2. AI_AGENT_GUIDELINES.md — backend-neutral UX and parity contract.
  3. .mex/ROUTER.md — choose the right pattern file for the task.
  4. docs/decisions/INDEX.md — load the relevant ADRs before touching a subsystem.
  5. docs/AGENT_DEUS_101.md — extended architecture and entrypoint map when you need depth.

Legacy note: CLAUDE.md still exists for Claude Code compatibility. It must mirror this file's intent, but this file is the source of truth.

Non-Negotiable Product Contract

Switching model or interface must not change the surrounding Deus experience. These must remain stable across backends:

  • Identity, tone, and long-term user preferences.
  • Memory and recall surfaces.
  • Chat commands and CLI commands.
  • Tool names, IPC semantics, and security boundaries.
  • Scheduled task behavior and delivery.
  • Credential isolation and filesystem boundaries.

Provider names are implementation detail unless the user explicitly asks about backend selection, billing, debugging, or provider-specific behavior.

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.

Deus AGENTS.md is an instructions file published in the GitHub repository sliamh11/Deus (51 stars, last pushed yesterday), licensed MIT. It adds 4,516 tokens to every session, about $0.0226 per session on Opus 5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
