sanad-agent: Instructions file for Codex

AGENTS.md

sanad-agent AGENTS.md is an instructions file for Codex, OpenCode from EastStarAI/sanad-agent. It costs 3,115 tokens per session, scanned A, original, MIT.

The main working contract for SanadAgent, an open-source system whose documentation directs how agents and developers work in the repository. It defines documentation layers, project discovery, worktree use, port offsets, and multi-agent coordination.

In plain words
What is it for?
Use it to orient agents, find the project feature index, follow rules for different code areas, coordinate parallel work, and keep documentation aligned with implementation.
Why use it?
It reduces incorrect changes caused by missing project rules or outdated understanding of the system’s architecture. Git worktrees are separate working directories for different branches, and port offsets prevent local services from conflicting.

Instructions file for CodexOpenCode

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

This is EastStarAI/sanad-agent's own configuration. It tells Codex and OpenCode how to work on sanad-agent 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 sanad-agent 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

sanad-agent 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 8d 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.

Sanad Agent Repository Contract

Documentation is the core constraint of this project. Treat /AGENTS.md (this file) as the Master Runtime Contract and bootloader for AI agents and human developers working on the open-source components of the SanadAgent system.

[!IMPORTANT]

🧭 Documentation is the most important part of this project

Treat every AGENTS.md file as a Runtime Contract, not as optional notes. Poor documentation causes AI agent behavior drift, architecture drift, and incorrect changes in the wrong layers.

  1. Functional Discoverability: For a complete, curated index of all codebase features, components, and guides, read docs/llms.txt immediately.
  2. Operational Rules: Plan, coordinate, and execute tasks using Git Worktrees, dynamic port offsets, and multi-agent systems.

1. Documentation Hierarchy

This repository uses a nested web of contracts. The closer the document is to the code, the more technical it should be:

  • AGENTS.md (this file / repository root) — Main Master Contract governing all open-source components.
  • client/AGENTS.md — Owns Flutter client UI contracts, widgets, and state registries (Flutter).
  • agent/AGENTS.md — Owns local Dart daemon interfaces, MCP servers, and background services (Dart).

Rules for AI Agents and Developers

  • Always read the local AGENTS.md file governing a subdirectory before making any edits in that directory.
  • Always update the relevant docs in the same session as the code change. This is a strict Definition of Done (DoD).
  • Review the closest owning AGENTS.md for every changed area. Update it only when the change alters a durable law, ownership boundary, invariant, or makes an existing statement stale; do not edit contracts merely to record implementation activity.
  • Keep higher-level docs abstract where appropriate and push implementation detail down into local leaf docs.
  • Keep lower-level docs concrete, explicit, and practical.
  • Remove stale or contradictory documentation immediately to prevent behavior drift.
  • Use README.md only as the public product source of truth for quick starts and pitches. Do not let README.md become a competing implementation contract; durable architecture and development contracts belong here in AGENTS.md and their nested child contracts.
  • Use fvm for all Flutter/Dart operations. Never execute global flutter/dart commands.
  • All referenced file paths must be relative to the workspace root.

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.
