Help developers use @chenglou/pretext, a small TypeScript text measurement library that computes exact text metrics without DOM reflows. Use when users mention pretext, @chenglou/pretext, @chenglou/pretext/rich-inline, measuring text height without triggering DOM reflow, measuring text height or line count in JS, auto-fitting font size to a container, flowing text around obstacles or images, laying out text per-line with variable widths, computing the natural/widest line width of a paragraph,...

Attach Proof Engine proofs to LLM-wiki claims. Use for ingest (extract claims, look up or commission proofs, rewrite pages with badges) and lint (re-verify citations, detect contradictions, report stale proofs) steps in wiki pipelines. Trigger phrases: "ingest wiki page", "lint wiki", "{{prove:}} markers", "verify wiki citations".

Create formal, verifiable proofs of claims with machine-checkable reasoning. Use when asked to prove, verify, fact-check, or rigorously establish whether a claim is true or false — mathematical, empirical, or mixed. Trigger phrases: "is it really true", "can you prove", "verify this", "fact-check this", "prove it", "show me the logic". Do NOT use for opinions, essays, or questions with no verifiable answer.

Use familiar companion tools for creative buddy/companion interactions. Handles fortunes, code roasts, haiku, stats, mood, lore, focus timers, and personality changes. Triggers when user addresses their companion by any name — "buddy" (Anthropic's UI label), "familiar", "companion", or whatever name the user uses for their companion — or by companion-specific intent: "tell me a fortune", "roast my code", "write a haiku", "show stats", "start a focus timer", "pomodoro", "be like Marvin", "chan...
