civitas: Instructions file for Codex

AGENTS.md

civitas AGENTS.md is an instructions file for Codex, OpenCode from minnhaaaaa/civitas. It costs 9,330 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Civitas, a food-procurement system in which multiple agents negotiate a purchasing plan and another agent reviews the evidence. They describe the project’s architecture and its rule that agreement alone is not proof of a correct decision.

In plain words
What is it for?
Use them when modifying or reviewing the Civitas codebase. They are guidance for development work, not a standalone procurement tool.
Why use it?
They give coding agents the project’s principles and constraints, helping them make changes that fit the intended design.

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

civitas 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 5d 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

Civitas — Autonomous Food Procurement through Agent Parliament and Agent Jury

Civitas is a multi-agent autonomous procurement system based on Problem Statement 5 of the AgentXcelerate challenge.

The official problem asks the system to determine what food to procure, how much to procure, from which suppliers, and how inventory should be distributed across locations while considering demand, inventory, supplier lead times, pricing, perishability, and location requirements.

Civitas goes beyond this baseline by introducing:

  1. Agent Parliament — autonomous agents with conflicting objectives negotiate a procurement plan.
  2. Agent Jury — evaluates whether the reasoning and evidence behind the agreement deserve to be trusted.
  3. Adaptive Replanning — a weak Jury result sends the system back into investigation and negotiation instead of allowing immediate execution.

1. Core Product Principle

Don't just make agents agree. Make sure their agreement deserves to be trusted.

The system must distinguish:

Agent Agreement
        ≠
Independent Evidence
        ≠
Correct Decision

A proposal supported by six agents can still be based on one underlying source or one propagated assumption.

Civitas therefore treats evidence lineage as a first-class object.


2. Architecture

The primary control loop is:

USER GOAL
    ↓
PLANNER
    ↓
PARLIAMENT
    ↓
INVESTIGATION THROUGH MCP
    ↓
COMPETING PROPOSALS
    ↓
NEGOTIATION
    ↓
CANDIDATE PLAN
    ↓
JURY
    ↓
┌───────────────┐
│               │
▼               ▼
APPROVE      INVESTIGATE
│               │
▼               ▼
EXECUTE       REPLAN
                │
                └──────→ PARLIAMENT

The Jury is therefore part of the autonomous planning loop.

It is not a final dashboard or post-hoc evaluator.

The primary product interface is conversational:

OPERATOR → CODEX → CIVITAS MCP SERVER → CONTROL LOOP
                                      → OPERATIONAL MCP PROVIDERS

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.
