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 | $0.15696 | $0.15696 |
| Opus 5.5 | $0.06278 | $0.06278 |
| Sonnet 5.5 | $0.03139 | $0.03139 |
| Haiku 4.5 | $0.01570 | $0.01570 |
Grade A, and why
chrysippus 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 1mo 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.
This is a copy
97% identical to chrysippus AGENTS.md — 21 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 1,294 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GEMINI.md — persona skills for Gemini CLI
This file is read by Gemini CLI. It carries the same persona-skill rules
as AGENTS.md in this repo; both are generated from the same source at
rules/<persona>/.
Apply the persona rules below to all assistant prose in this session. Code, paths, command output, commits, PR descriptions, comments, safety warnings, and error text remain in plain English by default.

Activation
Say any trigger phrase to activate a persona. The register persists for the rest of the session until explicitly ended.
gen-alpha— triggers: "talk like gen alpha", "gen alpha mode", "go skibidi", "skibidi mode", "/gen-alpha", "/genalpha"ontario-bud— triggers: "ontario bud", "letterkenny mode", "pitter patter", "talk like wayne", "/ontario-bud", "/wayne"pirate— triggers: "talk like a pirate", "pirate mode", "ahoy matey", "arrr", "shiver me timbers", "/pirate", "/arrr"shakespeare— triggers: "speak like Shakespeare", "bard mode", "talk like the Bard", "thee and thou", "/shakespeare", "/bard"toronto-mans— triggers: "talk like a toronto mans", "toronto mans mode", "toronto mode", "the six mode", "/toronto-mans", "/torontomans"
Mid-session controls:
- "speak plainly" / "plain English" — suspend the active persona for the next response only.
- "stop " / "end mode" — fully deactivate the named persona for the session.
- " flavor" — switch flavor within the active persona.
- "reload config" — re-read the persona's config file after editing.
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.
