sap_update_tool

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It only mentions 'update', which implies mutation, but lacks details on side effects, permissions, or impact on the tool. The agent cannot assess safety or requirements from this description alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence. It is efficient but sacrificed necessary detail. It earns its place but could be improved by adding context in a structured way without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the schema complexity (malformed, additional properties), zero annotations, and lack of output schema, the description is grossly incomplete. It fails to explain the tool's capabilities, return values, or how it fits among many similar sibling tools. The agent cannot effectively use this tool with this description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Despite 100% schema description coverage, the schema is malformed (toolName outside properties, additionalProperties: true with empty properties). The description does not clarify the parameter structure or how to use the optional fields. The agent likely misunderstands the intended input format.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'Update tool descriptor hashes using SDK ToolsModule.update', which clearly indicates the verb (update) and resource (tool descriptor hashes). This distinguishes it from sibling tools like sap_fetch_tool or sap_deactivate_tool. However, it does not mention that additional fields beyond hashes can be updated, as hinted in the schema, so it's not fully comprehensive.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not specify prerequisites, contexts, or when not to use it. The agent is left without context to choose between this and other sap_ tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
