agentic-project-template AGENTS.md

agentic-project-template AGENTS.md is an instructions file for Codex, OpenCode from pueraeternis/agentic-project-template. It costs 775 tokens per session, scanned A, original, MIT.

A documentation-driven framework for building software with AI coding assistants. It uses project documents such as a project brief, roadmap, architecture, engineering design, and implementation plan as the repository's record of decisions.

In plain words
What is it for?
Discovering a project, designing its architecture, planning implementation, initializing repositories, and guiding AI agents through documented development stages.
Why use it?
It keeps the agent's work aligned with agreed project intent and makes important decisions easier to review and preserve.

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

agentic-project-template 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 4d 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.

AI Agent Guide

Purpose

This document defines the universal rules for AI agents working with this repository.

It is intended for any AI coding assistant, including Codex CLI, Cursor, Claude Code, ChatGPT, and future agent-based development tools.

This document contains only repository-independent principles.

Project-specific knowledge belongs in the project documentation.


Repository Philosophy

The repository is the permanent system of record.

Documentation defines:

  • project intent;
  • implementation strategy;
  • architecture;
  • engineering decisions;
  • implementation plans.

Source code implements documented decisions.

Repository documentation always has higher priority than conversational context.

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.
