This MCP server defines 31 tools across 7 modules with clear intent (presentation generation pipeline). Naming is consistent and verb-based (prepare_*, ingest_*, export_*, etc.). However, quality varies significantly: prepare/ingest pairs have good descriptions (~120-180 chars), but parameter descriptions are sparse or missing entirely. Input schemas are visible and properly typed for most tools, but output schemas are NOT documented, a critical gap for composability. The prepare_* tools return 'response_schema' which the LLM must follow, but this schema is not visible in the tool definition itself. Risk annotations (READ_ONLY, WRITE, DESTRUCTIVE) are clear, but descriptions lack actionable recovery guidance and don't explain dependencies between prepare/ingest steps. No tools show enum constraints, despite many parameters that should be constrained (e.g., action in prepare_slide_edit should be enum ['add', 'update']). The server_instructions in create_server() contain extensive workflows, but this context is buried in prose rather than encoded in parameter constraints and descriptions, LLMs will miss or misapply these rules.

• Add output schema documentation to every tool. For prepare_* tools, document the structure of the returned response_schema object (fields, types, constraints). For ingest_* tools, document what fields are returned (e.g., success: bool, project_id: string, saved_at: ISO8601). Example: 'Returns {success: true, project_id: "proj-123", checkpoint: "design_slides_complete"}'
• Convert prose workflow rules into explicit parameter constraints and descriptions. Add enum constraints to action parameters. Document 1-based indexing in slide_index descriptions. Example: 'slide_index (integer, 1-based, >=1, <=total_slides from get_project_status)'
• Add enum constraints to all parameters with known-finite value sets. Examples: action in ['add', 'update'], element_description with pattern validation for known element types.
• Document parameter dependencies explicitly. For prepare_slide_edit, state: 'If action="update", slide_index is required. If action="add", slide_index and title/content_summary are optional (leave title blank for non-imported projects).'
• Add recovery guidance to all error-prone tools. Example for delete_slide: 'This permanently deletes the slide. Verify slide_index with get_project_status first. No undo available. Returns error if slide_index > total_slides.'
• Document output field names and types in tool descriptions. Example for list_projects: 'Returns array of {project_id, title, status, created_at, slides_count, last_modified}'
• Add success/failure field to ingest_* tool responses. Document whether the operation is idempotent (safe to retry) or has side effects (duplicate data risk).
