Document co-authoring
Plan and write proposals, specifications, RFCs and decision documents.
Skills
Skills give a model a clear method for recurring work: how to analyse information, create useful documents and follow the workflows your organisation relies on.
For well-scoped tasks, that guidance can help a smaller model follow a reliable process—so you can match the model to the work.

Capabilities
Browse the kinds of work a model can take on with reusable guidance. A skill explains when it applies and gives the model a workflow to follow with the tools and information available to your team.
Plan and write proposals, specifications, RFCs and decision documents.
Compare documents against rubrics and references with traceable evidence.
Create polished printable reports, forms, checklists and PDFs.
Extract source-located facts from uploaded documents for analysis.
Find and use evidence from your assistant's indexed datasets.
Inspect, filter, summarize and transform files in the workspace.
Create, query and maintain SQLite databases and structured data.
Create reveal.js slide decks and presentation-style artifacts.
Answer questions grounded in uploaded images, diagrams and screenshots.

Package a repeatable category of work in SKILL.md. Explain when the method applies and how the model should carry it out, then add supporting references, templates, examples or executable helpers. The model can load the guidance when it matches the task.
