multimodel-dev-os AGENTS.md is an instructions file for Codex, OpenCode from rizvee/multimodel-dev-os. It costs 602 tokens per session, scanned A, original, MIT.

Repository instructions for MultiModel Dev OS, a local Node.js command-line tool and configuration standard for AI coding agents. They describe its build, test, verification, coding, and file-organization rules.

In plain words
What is it for?
Use them when editing the project, running its build or tests, performing strict verification, or following its JavaScript and file-layout conventions.
Why use it?
They give agents consistent boundaries for project structure, memory, tasks, and registry safety, and define how changes should be checked.

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

This is rizvee/multimodel-dev-os's own configuration. It tells Codex and OpenCode how to work on multimodel-dev-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 multimodel-dev-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

multimodel-dev-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.

Project Overview

project: multimodel-dev-os stack: Node.js (ES modules), esbuild, Vitest description: MultiModel Dev OS is a zero-dependency local CLI and developer configuration standard that enforces structure, memory, tasks, and registry safety boundaries for AI coding agents.

Build Commands

build: npm run build (compiles src/ to bin/multimodel-dev-os.js)
test:  npm test (runs vitest suites)
verify: node scripts/verify.js (runs strict audit checks)

Coding Conventions

  • Language: JavaScript (ES Modules, Node.js native API)
  • Framework: Zero runtime dependencies (standard library crypto, fs, path, readline, https, etc.)
  • Style guide: Clear JSDoc typing, deterministic canonical serializations, timing-safe crypto
  • Type checking: JSDoc type comments
  • Formatting: 2-space indentation, single-shebang binary layout

File Structure Rules

src/       -> Application source code
bin/       -> Standalone built binary (do not edit bin/ directly; edit src/)
tests/     -> Unit test files and mock fixtures
docs/      -> Developer manuals and architecture documentation
scripts/   -> Packaging, compilation, and validation scripts

Boundaries

no-touch:
  - .env
  - .env.local
  - node_modules/
  - package-lock.json (do not manually edit)
  - bin/multimodel-dev-os.js (auto-generated by esbuild, modify src/)
  - .ai/registry-signing-key (gitignored private key, generate via keygen)

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.
