This monorepo contains 9 tools across 4 packages (api-hub, roadmap, notes, auth). Tool definitions are visible in package.json files and referenced source locations, but critical quality gaps exist: (1) Three tools named 'search' create ambiguity, LLMs cannot distinguish between searching API Hub artifacts, Road Map deliverables, and SAP Notes without reading full descriptions. (2) Input schemas are present but sparse, most parameters lack type constraints (enums, min/max). (3) Descriptions are present but generic; many lack WHEN-to-use guidance or dependency hints. (4) No output schemas documented, LLMs cannot plan downstream calls. (5) Error handling not visible in provided code. (6) Tool 'resources' and 'spec' operate on artifact IDs but no guidance on how to obtain valid IDs. Average per-tool score: 42/100.

• Rename the three 'search' tools to 'search_api_hub_artifacts', 'search_roadmap_deliverables', and 'search_sap_notes' to eliminate ambiguity and enable LLMs to select the correct tool by name alone.
• Document output schemas for all tools. Specify which fields are returned (e.g., search returns [{ id, name, description, categoryKey }]) so LLMs can chain calls and extract IDs for downstream fetch/resources/spec calls.
• Convert free-form string parameters to enums. Define valid values for 'categoryKey' (API, Events, CDSViews, S4HANACloudBADI, etc.) and 'artifactType' (API, Event, CDSVIEW, BADI, etc.) as JSON Schema enums.
• Add min/max constraints to numeric parameters. E.g., 'top' should be 1 - 100 (default 20), 'skip' should be 0 - 10000. Include these in both schema and description.
• Enhance descriptions with dependency hints. E.g., 'fetch' description: 'Fetch artifact details by ID. Obtain IDs by calling search_api_hub_artifacts() first. Returns specification, documentation, and metadata.'
