agentic-engineering-framework: Instructions file for Codex

AGENTS.md

agentic-engineering-framework AGENTS.md is an instructions file for Codex, OpenCode from DimitriGeelen/agentic-engineering-framework. It costs 1,359 tokens per session, scanned C, original, Apache-2.0.

An AGENTS.md instruction set for an agentic engineering framework, meaning rules for governing AI coding agents. It defines task tracking, commit references, approval for destructive commands, and session handovers.

In plain words
What is it for?
Use it to require a task before editing, link commits to tasks, request approval for destructive commands, and preserve context at the end of a session.
Why use it?
It makes work traceable and places checks around risky actions instead of relying only on the agent to follow informal rules.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is DimitriGeelen/agentic-engineering-framework's own configuration. It tells Codex and OpenCode how to work on agentic-engineering-framework itself, so it is not a mod to install elsewhere.

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 C, and why

agentic-engineering-framework AGENTS.md scanned grade C 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 24d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

4. **Destructive commands require approval.** Force push, hard reset, `rm -rf`, DROP TABLE → `fw tier0 approve`.

AGENTS.md — Agentic Engineering Framework

Standard agent instruction file (AAIF/Linux Foundation convention). For Claude Code-specific integration, see CLAUDE.md. For the full provider-neutral guide, see FRAMEWORK.md.

Identity

  • Name: Agentic Engineering Framework
  • Purpose: Governance framework for AI coding agents — enforces task traceability, structural gates, session continuity, and audit trails.
  • Version: 1.0.0

Core Principle

Nothing gets done without a task. This is enforced structurally, not by agent discipline.

Rules

  1. Create a task before editing files. Use fw work-on "description" --type build to create and focus.
  2. Every commit references a task. Format: T-XXX: description. Enforced by commit-msg hook.
  3. Never bypass structural gates. If a gate blocks you, stop and ask the human.
  4. Destructive commands require approval. Force push, hard reset, rm -rf, DROP TABLE → fw tier0 approve.
  5. Generate a handover before ending. Use fw handover --commit to preserve session context.
  6. Commands for the operator ship as ONE line (T-3675, standing directive). Never paste a block of commands. fw runme new <name> -- '<cmd>' … writes a logged runme.sh; hand over the printed bash /abs/path/runme.sh line, then fw runme watch <name> and read the result yourself. Never ask the operator to paste output back.

Authority Model

Human     → SOVEREIGNTY  → Can override anything
Framework → AUTHORITY    → Enforces rules, checks gates
Agent     → INITIATIVE   → Can propose, never decides

Quick Commands

Action Command

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.
