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

This is ellmos-ai/companion-for-agy's own configuration. It tells Codex and OpenCode how to work on companion-for-agy 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 companion-for-agy configures →

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

companion-for-agy 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 today.

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.

What it actually says

AGENTS.md — Multi-Agent Multi-Framework Guidance (companion-for-agy)

Zweck: Einstiegspunkt für Agent-Frameworks (Antigravity/Gemini, Codex CLI, Claude CLI) im Repository companion-for-agy.

Lies und folge den Hauptregeln:

  1. Globale Regeln: ~/CLAUDE.md (zentrale Regeldatei des jeweiligen Hosts)
  2. Projekt-Steuerung: CLAUDE.md und README.md

Multi-Agenten-Koordination & Lock-Sicherheit

  • Vor Änderungen am Projekt prüfen, ob eine aktive LOCK*.txt im Ordner liegt (LOCK.txt = ganzes Projekt, LOCK.<scope>.txt = Komponente).
  • Gesperrt → Datei/Ordner nicht anpacken. LOCK.user*.txt NIEMALS entfernen.
  • Pfad-Autorität: Änderungen direkt im lokalen Quellordner (dem lokalen Klon dieses Repos, nicht in einem Cloud-Sync-Ordner) durchführen.

Qualitäts-Gates & Testanweisungen

  • Vor jedem Commit/Deployment die Testsuite ausführen:
    npm test
    
  • CHANGELOG.md und llms.txt Metadaten-Zeitstempel pflegen.

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.
