shakespeare

shakespeare is a command for coding agents from kbatsu/chrysippus. It costs 21 tokens per session (202 once invoked), scanned A, original, MIT.

A command that switches the session into a Shakespeare-inspired speaking style, using Early Modern English. It can also select among the persona's available style variants.

In plain words
What is it for?
Use it for role-play, creative writing, demonstrations, or testing how an agent behaves under a specific historical speaking style.
Why use it?
It lets you change the agent's tone for the rest of the session without manually repeating the style instructions. You can switch variants or return to plain speech using the documented commands.

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

shakespeare 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 4d 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

Activate the shakespeare skill for this session.

Read .claude/skills/shakespeare/SKILL.md in full and follow its §1 activation rules — including the 3-line flavor announcement the skill expects to make on activation (current flavor, other flavors + switch syntax, stop syntax). Also read .claude/skills/shakespeare/shakespeare.config for the active flavor and preservation toggles.

If the user passed a flavor argument (e.g., /chrysippus:shakespeare tavern or /shakespeare tavern), activate with that flavor from the start — the announcement's Line 1 should reflect it.

Mid-session overrides documented in SKILL.md §1 still apply — "speak plainly", "reload shakespeare config", and the per-flavor switch phrases.

Changes

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.
