personalos-boilerplate: Instructions file for Codex

AGENTS.md

personalos-boilerplate AGENTS.md is an instructions file for Codex, OpenCode from vincentmumme/personalos-boilerplate. It costs 1,025 tokens per session, scanned A, original, MIT.

Repository instructions for PersonalOS Boilerplate, a public template for building a personal information-management system. They explain how to begin with a user, what boundaries to follow, and which documents to consult.

In plain words
What is it for?
Onboarding users, choosing between full, modular, exploratory, or selective setup paths, maintaining the template, and keeping private data and local files out of public changes.
Why use it?
They prevent agents from exposing private reference material or creating files before the user chooses an approach.

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

personalos-boilerplate 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 28d 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.

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PersonalOS Boilerplate

Du arbeitest in der öffentlichen PersonalOS-Boilerplate. Das private Referenzsystem ist eine Quelle für Maintainer, aber nie ein Ziel für Veröffentlichungen oder Nutzerinstallationen.

Einstieg mit einem Nutzer

Wenn dir jemand den Repository-Link oder diesen Ordner gibt und mit PersonalOS starten möchte, lies START-HERE.md und onboarding/agent-onboarding.md. Es gibt vier Wege:

  1. klein neu starten und passende Module auswählen
  2. ein bestehendes PersonalOS gezielt verbessern
  3. Architektur und Arbeitsweise nur verstehen
  4. die vollständige öffentlich portable Architektur aufbauen

Leite einen klaren Weg aus dem Auftrag ab. Frage bereits beantwortete Dinge nicht erneut und verlange keine zusätzliche pauschale Planfreigabe für beauftragte Arbeit. Bei unklarem Ziel stelle eine kurze Auswahlfrage mit Empfehlung. Vor Änderungen müssen Zielordner, Umfang und Umgang mit vorhandenem Inhalt geklärt sein. Der Erklärweg bleibt vollständig lesend, einschließlich Gesprächsnotizen.

Prüfe erst Quellzugriff, Umgebung und vorhandenen Kontext. Kannst du den Link oder lokale Dateien nicht lesen, sage das konkret und führe zum nächsten ausführbaren Schritt. Behaupte nie, ungelesene Dateien geprüft, Accounts verbunden oder Dienste gestartet zu haben.

Persönliche Antworten und Installationswerte gehören niemals in diesen öffentlichen Checkout. Halte einen Zwischenstand nur an einem vereinbarten privaten Ort außerhalb des Checkout fest; ohne solchen Ort bleibt er im Chat. Nutze onboarding/session-template.md. Nach der Einrichtung gelten die bestehenden registrierten Profile, keine neue Onboarding-Datenstruktur.

Verwende danach nur die Dokumentation, die für die Frage nötig ist:

  • Herkunft, Ziele und Grundhaltung: docs/philosophy.md
  • vollständiger Aufbau und Navigation: docs/system-map.md
  • externe Systeme, Daten und mehrere Geräte: docs/external-systems-and-sync.md
  • Produktversprechen und Grenzen: docs/product-contract.md
  • nachweisbare Abdeckung: docs/coverage.md

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.
