Breaking

The skill object model is slimmed down. The runtime skill object now carries only name, description, and content (richtext). The displayName and attachments attributes and the alwaysOn / enabled flags have been removed, and the find_skill tool is gone. A skill's identity and label are now its name. If you authored skill records against the old shape, drop those fields. See Agents.

Full-context skill disclosure. Every skill — built-in or tenant-authored — is now listed by name and description in an ## Available Skills section of the agent system prompt. The agent loads a skill's full content on demand with get_skill before starting a specialized task, so there is no separate discovery step or per-skill flag to manage.
New skill-creator built-in skill. Agents can now author a skill from scratch or import one from the skills.sh marketplace and save it as a reusable skill record. The E2B sandbox template preinstalls the skills CLI to support marketplace imports.
Default Skills list view. The sealed skill object ships with a default list view (columns name, description, sorted by name) so authored skills are browsable out of the box.

Model pricing resolves by apiModelId. Pricing and capability lookups now match on a model's apiModelId, not only its id, so aliased or provider-prefixed model identifiers resolve to the correct rates.
Localized tool-part copy. The attached-records suffix in the AI tool-part component is now translated, and the French locale gained a translation for the displayTemplate label.
