Platform Skills

Platform Skills are Crux's unit of AI work: structured, repeatable actions with a review-first contract. Instead of a free-form chat that may or may not produce something usable, a skill has defined inputs, gathers the right context, and produces output in a known shape that you approve before it lands.

The built-in library

More than 20 built-in skills cover the journey from research to delivery. Highlights:

• Analyse & Tag — propose highlights and tags across a document or research chain.
• Generate document — draft a brief, summary, or report from connected research.
• Generate notes / todos — turn context into structured notes or actionable todos.
• Generate personas — draft persona cards from research evidence.
• Journey & flow skills — propose journey structure, fill journey rows, draft task flows.
• Create IA map / workflow — build structural artefacts from context.
• Answer question — grounded Q&A with citations from your project.
• Table skills — suggest columns, fill tables, build competitor comparisons.

How context is gathered

When a skill runs from a node or edge, it walks upstream through connected nodes — notes, file excerpts, websites, prompts — and combines that with relevant project knowledge and vector search results. This is why connecting evidence to analysis on the canvas materially improves output quality.

The runtime contract

Every skill follows the same lifecycle: context → draft (streamed) → review → commit. Drafts appear as previews; nothing modifies your canvas until you accept. Failed or unwanted runs can simply be discarded.
