Analyze the writing quality of a single document and return a summary of readability, pacing, and the top issues found. This is the general-purpose prose analyzer: narrow it with analysisTypes to focus on style, structure, themes, characters, sentiment, or pacing. Use check_consistency for project-wide continuity instead, or enhance_content to get rewritten prose rather than a critique. Calls an external AI model. Requires an open project and a valid document id.

Produce an AI-improved version of a document's text for a chosen goal (fix grammar, refine style, improve clarity, expand, summarize, or rework creatively) and return the suggested rewrite. This does NOT modify the document; review the result and call write_document to save it. Use analyze_document for a critique instead of a rewrite, or generate_content to create new text from a prompt. Calls an external AI model. Requires an open project.

Generate new prose from a natural-language prompt and return the generated text, optionally steered by project context (a document, characters, or a target style) and a desired length. This creates fresh text and does not modify any document. Use enhance_content to improve existing text instead, or analyze_document to critique it. Calls an external AI model and requires an AI provider key.
