Demo 1 — "What does this repo do?"

🎭 shakespeare — courtly "A trove of personas, good sir — five registers for thy AI agent to don. Bardic, piratey, youthful, Toronto-coded, or rural-Ontarian. The code remaineth verbatim; only the voice doth shift."

🏴‍☠️ pirate — scurvy-dog "Aye matey — five voices for Claude Code and its kin. Ye can speak like the Bard, a buccaneer, a gen-alpha, a Toronto mans, or an Ontario bud. Code stays as writ; only the words change."

🫠 gen-alpha — unhinged "ok so 5 voices for claude code. shakespeare pirate gen-alpha toronto-mans ontario-bud. code untouched fr. purely for vibes no cap. also made by millennials bc of course."

6️⃣ toronto-mans — mans "Mans ship five persona skills for AI coding agents fam. Bard, pirate, gen-alpha, toronto-mans, and ontario-bud — you're reading it. Code stays plain no cap, only the voice shifts still."

🇨🇦 ontario-bud — bud "Five voices in here, bud. Bardic, piratey, gen-alpha, toronto-mans, and ontario-bud — that's me. Code stays plain English, just the voice changes. Pitter patter."

Demo 2 — "Bug on line 42 of parse.ts — null isn't handled. Advice?"

🎭 shakespeare "Upon line 42 of parse.ts lurketh a bug most grievous: null is given no welcome, and the function doth crash. Place a null-guard afore the call, that the stream may flow unbroken."

🏴‍☠️ pirate "Kraken on line 42 of parse.ts, matey — null walks in and the function be capsized. Add a null-guard, and the seas stay calm."

🫠 gen-alpha "line 42 of parse.ts is cooked — null not handled. add a guard, move on. W fix."

6️⃣ toronto-mans "Bug on line 42 of parse.ts still fam — null ain't being handled. Easy ting to fix: null-guard before the call. Bare simple no cap."

🇨🇦 ontario-bud "Bug on line 42 of parse.ts there, bud — null ain't being handled. Easy fix: drop a null-guard in afore the call. Sorted."

Notice parse.ts and null in every response — backtick contents stay verbatim regardless of register. That's the preservation rule, one of several. See the full config model →

What chrysippus is

Each persona changes how the agent talks (register, vocabulary, tone) while leaving what it does untouched (code, commits, errors, tool output). Inspired by caveman — same mechanism, opposite goal. caveman compresses speech to save tokens; chrysippus retunes register for fun. No savings here, just vibes.

What's preserved regardless of active persona

  • Anything inside backticks — hard rule, not configurable.
  • Commit messages, PR descriptions, code comments — plain English by default.
  • Safety warnings, destructive-op confirmations, error text — plain English by default.
  • Replies in non-English languages — the agent answers in the user's language, in plain prose.
  • Most-recent-wins precedence if multiple personas activate in the same session.

Docs

  • Install — per-agent setup (Claude Code, Cursor, Codex, Windsurf, Aider, Cline, Gemini).
  • Personas — one page per skill with demos, flavor matrix, and register-specific guardrails.
