Without document_id it creates a new document on the board; with the document_id an earlier call returned it replaces that document's title and whole text and keeps its id, so publishing a new version never adds a duplicate. Pass the updated_at the last answer returned as expected_updated_at: a document a member saved since is refused and left unchanged. A replace overwrites the previous title and text, which cannot be brought back. It answers the document's id, its new updated_at and the path a member opens it at. Not for drafting an article that opens the Splash Pad's article workflow — that is `splash_pad.write_article`. Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with `workspace_ambiguous` and lists the choices — offer them, never pick one. ## OpenAPI ````yaml /openapi.json post /api/v1/tools/board.write_document openapi: 3.1.0 info: title: Goosy Bear API version: 1.0.0-beta summary: Manage workspace content, projects, Data tables, Pages, library and credits. description: >- BETA. This API is in beta: paths, request shapes and response envelopes may change, and every response carries an `x-goosy-api: beta` header for as long as that is true. A change is additive, or it is deprecated first: a response to a call that uses a deprecated feature carries `Deprecation` and `Sunset` headers, and nothing is removed until at least 90 days after its deprecation. Pin the OpenAPI document you generated against and re-generate when it changes. servers: - url: https://app.goosybear.ai description: Production security: - tenantApiKey: [] paths: /api/v1/tools/board.write_document: post: tags: - board summary: Call board.write_document description: >- 'put the call script on the sales board', 'replace the Gravity call script with this version', 'update the onboarding doc' — create one document on a board of this workspace, or replace one in place.
