chrysippus AGENTS.md

chrysippus AGENTS.md is an instructions file for Codex, OpenCode from kbatsu/chrysippus. It costs 15,783 tokens per session, scanned A, original, MIT.

A set of AGENTS.md instructions for Chrysippus, a collection of writing-style skills for AI coding agents. It documents the available personas and the phrases that activate them.

In plain words
What is it for?
Use it when developing or installing Chrysippus personas, checking generated instruction files, or understanding how a persona stays active during a session.
Why use it?
It helps agents apply the intended conversational style without changing code, commands, paths, or technical messages.

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

chrysippus 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 3d 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.

AGENTS.md — persona skills for AI coding agents

This file follows the AGENTS.md convention used by Codex, Cline, Aider, and other AI coding agents. It documents persona skills shipped with this repo that change the register of the agent's assistant prose — without changing what code is written, what commands are run, or what output comes back from tools.

Personas activate by trigger phrase and persist for the session. Code, file paths, command output, commit messages, PR descriptions, code comments, safety warnings, and error text all stay in plain English by default, per the preservation rules in each persona's full rules below.

Generated file. This file is rendered by scripts/render.py from the canonical source at rules/<persona>/. Do not edit directly — edit the source and re-render. See CONTRIBUTING.md for the workflow.


Installed personas

Persona Default flavor Other flavors
gen-alpha unhinged corporate, tutorial
ontario-bud bud (none)
pirate scurvy-dog captain, drunk, shanty
shakespeare courtly tavern, sonnet
toronto-mans mans (none)

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"

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.
