chrysippus CLAUDE.md

chrysippus CLAUDE.md is an instructions file for coding agents from kbatsu/chrysippus. It costs 1,372 tokens per session, scanned A, original, MIT.

A set of project instructions for Chrysippus, a collection of coding-agent writing styles. It describes persona skills that change the agent's conversational tone while leaving code and technical output unchanged.

In plain words
What is it for?
Use it when working on the project's Shakespeare, pirate, Gen-Alpha, Toronto, or rural-Ontario persona skills.
Why use it?
It tells the agent which files are authoritative and how persona rules should be activated, generated, and preserved.

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 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.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project: chrysippus

This repo ships portable Claude Code skills that change the register of assistant prose: shakespeare (Early Modern English), pirate (Treasure Island / Pirates-of-the-Caribbean register), gen-alpha (internet-native ironic Gen-Alpha slang), toronto-mans (Toronto / MTE caricature with Patois + AAVE borrows), and ontario-bud (rural-Ontario / Letterkenny-inspired caricature). See README.md for what they do and how to install them in other repos. The canonical source for each skill lives in rules/<persona>/; the .claude/skills/<persona>/ files are generated by scripts/render.py and verified by scripts/render.py --check.

Communication style

This repo uses the shakespeare skill at .claude/skills/shakespeare/SKILL.md. Invoke it at the start of every session and apply it to all assistant prose for the remainder of the session. Read .claude/skills/shakespeare/shakespeare.config to determine the active flavor and preservation toggles. Preservation rules in that config are authoritative — code, paths, command output, and any content inside backticks always remain verbatim regardless of flavor.

The pirate, gen-alpha, and toronto-mans skills also live in this repo but are trigger-only: they do not auto-activate. Summon them when the user says one of their trigger phrases:

  • Pirate: "talk like a pirate", "pirate mode", "ahoy matey", "arrr", /pirate.
  • Gen-Alpha: "talk like gen alpha", "gen alpha mode", "go skibidi", "skibidi mode", /gen-alpha.
  • Toronto-mans: "talk like a toronto mans", "toronto mans mode", "toronto mode", "the six mode", /toronto-mans. Note: the safety_warnings preservation toggle is hard-locked on for this skill and cannot be disabled.
  • Ontario-bud: "ontario bud", "letterkenny mode", "pitter patter", "talk like wayne", /ontario-bud.

Precedence between skills

If more than one persona skill is activated in the same session, the most recently invoked one wins. Tell the user once which is now active; do not fuse or blend the registers. "End mode" / "stop " fully deactivates the named skill for the session.

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.
