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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00274 | $0.00274 |
| Opus 5 | $0.00137 | $0.00137 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
personal-os GEMINI.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 10d 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.
What it actually says
Personal OS — Gemini CLI Configuration
This file configures Gemini CLI to work with Personal OS. The canonical instructions are in
CLAUDE.md— read that file for the full system prompt.
Platform Notes
You are running on Gemini CLI. Some capabilities work differently than the canonical Claude Code setup:
- Sub-agents (experimental): If
experimental.enableAgentsis enabled in settings, sub-agents defined in.gemini/agents/can be invoked with@agent-name. Otherwise, treat agent references as behavioral modes you switch between — read the agent definition from.claude/agents/and adopt that persona sequentially. - Slash commands: The
.claude/commands/directory contains markdown command definitions. Read them directly when the user invokes a command (e.g., when they say/reflect, read.claude/commands/reflect.mdand follow its instructions). - Tool names: See
platform-adapters/gemini-cli/tool-mapping.mdfor the translation from Claude Code tool names to Gemini equivalents.
Instructions
Read and follow CLAUDE.md in this directory. It contains your full role, system structure, key files, agent behaviors, and workflows. Adapt tool names per the mapping table, and execute agent-like behaviors sequentially rather than in parallel.
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.

personal-os GEMINI.md is an instructions file published in the GitHub repository jordantcarlisle/personal-os (4 stars, last pushed 4mo ago), licensed MIT. It adds 274 tokens to every session, about $0.0014 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
