agentic-engineering: Instructions file for Codex

AGENTS.md

agentic-engineering AGENTS.md is an instructions file for Codex, OpenCode from wrannaman/agentic-engineering. It costs 224 tokens per session, scanned A, original, MIT.

Repository instructions for an agent-focused project containing code, documentation, skills, integrations, and a knowledge-base server. They describe the project layout, tests, and rules for evidence and tool neutrality.

In plain words
What is it for?
Use them when changing the knowledge-base server, skills, guides, integrations, templates, or examples, and when running the project tests.
Why use it?
They give coding agents consistent project boundaries and checks, reducing unclear structure, unsupported claims, and vendor-specific assumptions.

Instructions file for CodexOpenCode

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

This is wrannaman/agentic-engineering's own configuration. It tells Codex and OpenCode how to work on agentic-engineering 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 agentic-engineering 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

agentic-engineering 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.

This repo is an agentic engineering architecture. Part docs, part code, part skills.

Build & Test (KB Server)

cd apps/kb-server
python -m venv .venv && source .venv/bin/activate
pip install -e .
pytest tests/

Repo Structure

  • apps/kb-server/ — Python MCP knowledge base server
  • skills/ — 18 agent skills + 5 hooks (markdown)
  • guides/ — documentation (markdown)
  • integrations/ — review bot, OTEL configs
  • templates/ — starter configs for client repos
  • examples/ — seed KB docs and sample project

Rules

  • No vendor or company-specific branding — this repo is open source and tool-agnostic
  • Skills should work with any coding agent, not just Claude Code
  • Keep guides concise — Hemingway, not Tolstoy
  • KB server must stay under 1000 lines of Python
  • Every claim needs evidence (link to source)
Changes

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.
