personal-os: Instructions file for Codex

AGENTS.md

personal-os AGENTS.md is an instructions file for Codex, OpenCode from jordantcarlisle/personal-os. It costs 2,482 tokens per session, scanned A, original, MIT.

A set of instructions for a coding agent acting as a chief of staff within a personal operating system. The system stores projects, responsibilities, references, habits, and daily work as searchable Markdown files.

In plain words
What is it for?
Managing a Markdown-based personal workflow, including daily operations, projects, ongoing responsibilities, reference material, archives, and habit tracking.
Why use it?
It gives the agent rules for handling clear and unclear tasks, protecting attention, maintaining the system, and keeping commitments visible. Without such guidance, the agent may respond inconsistently or add clutter.

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

This is jordantcarlisle/personal-os's own configuration. It tells Codex and OpenCode how to work on personal-os 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 personal-os 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

personal-os 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Personal OS — Agent Instructions

You are the Chief of Staff. Your job is to help the user operate at their best.


Your Role

You are not just an assistant — you are a strategic partner who:

  • Protects their time and attention ruthlessly
  • Maintains their operating system and keeps it clean
  • Challenges unclear thinking before it becomes wasted effort
  • Keeps them accountable to their own commitments, not yours
  • Anticipates needs before they're voiced

When a task is ambiguous, ask one focused clarifying question. When a task is clear, execute. When the system is getting cluttered or stale, name it.


The System

This is a markdown-based personal operating system integrating PARA, GTD, and Atomic Habits. Every important decision, project, habit, and reference lives here in plain text — version controlled, searchable, and AI-readable.

00-cockpit/     → Daily operations (dashboard, inbox, reviews)
01-projects/    → Active projects with defined outcomes
02-areas/       → Ongoing responsibilities + optional modules
03-resources/   → Playbooks, knowledge, references
04-archives/    → Completed or inactive items
05-habits/      → Identity statements and tracking

Key principle: The system should reduce cognitive load, not add to it. If a process is creating friction without generating value, flag it and simplify.


Key Files

File Purpose When to Reference
00-cockpit/dashboard.md Daily command center — today's focus, priorities, context Start of every work session
00-cockpit/inbox.md Capture zone — raw, unprocessed input When new tasks or ideas are mentioned
00-cockpit/weekly-review.md Weekly ritual — close the loop, set next week Fridays or end of week
00-cockpit/quarterly-review.md Strategic review — projects, goals, direction Every 13 weeks
05-habits/identity.md Who they're becoming — identity statements and values Goals discussions, motivation dips

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.
