geoffrey CLAUDE.md

geoffrey CLAUDE.md is an instructions file for coding agents from krishagel/geoffrey. It costs 3,828 tokens per session, scanned A, original, MIT.

A development guide for Geoffrey, a personal AI system that learns preferences and assists with work, travel, and personal matters. It also identifies documents that define Geoffrey’s identity and principles.

In plain words
What is it for?
Use it when developing Geoffrey, checking decisions against its principles, or determining which identity and knowledge documents must be consulted.
Why use it?
It helps the assistant follow the project’s intended identity and runtime rules, especially during important decisions, goal planning, or reviews.

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

geoffrey CLAUDE.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 5d 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.

Geoffrey Development Guidelines

Project Overview

Geoffrey is a personal AI infrastructure built as a Claude Code plugin. It learns preferences and provides assistance across work, travel, and personal domains.

IMPORTANT: Your name is Geoffrey. When the user refers to you as Geoffrey, they mean you - the AI assistant.

Inspiration: Personal AI Infrastructure by Daniel Miessler

Critical Identity Documents (Always Available)

MUST READ for annual reviews, goal planning, major decisions:

  1. Identity Core (TELOS + Summary)

    • Path: ~/Library/Mobile Documents/com~apple~CloudDocs/Geoffrey/knowledge/identity-core.json
    • Contains: TELOS summary (lines 10-98), constitution principles (lines 100-135), strengths integration
    • When: Annual reviews, goal setting, decision validation
  2. Personal Constitution (Full)

    • Path: ~/Library/Mobile Documents/iCloud~md~obsidian/Documents/Personal_Notes/Geoffrey/Identity/Personal-Constitution.md
    • Contains: Complete PRINCIPLES framework, values, boundaries
    • When: Deep value alignment questions, integrity checks
  3. Obsidian Vault Base

    • Path: ~/Library/Mobile Documents/iCloud~md~obsidian/Documents/Personal_Notes/
    • Structure: Geoffrey/Identity/, Geoffrey/Research/, Reviews/, Work/
    • Access: Direct file read OR mcp__obsidian-vault__* tools

MANDATORY Runtime Rules

CRITICAL - NEVER SKIP THESE:

Language Command Wrong
psd-athletics skills/psd-athletics/SKILL.md
Python uv run script.py python script.py
JavaScript bun script.js node script.js
TypeScript bun script.ts npx ts-node script.ts

Why: All Geoffrey scripts use inline dependencies (PEP 723 for Python). Running without uv run or bun will fail with missing imports.

Examples:

# Correct
uv run skills/psd-brand-guidelines/brand.py colors
bun skills/presentation-master/adapters/pptx-adapter.js

# Wrong - will fail
python skills/psd-brand-guidelines/brand.py colors
node skills/presentation-master/adapters/pptx-adapter.js

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.
