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

Annotations indicate readOnlyHint=false and destructiveHint=false. The description adds behavioral context: it is a 'free local tool', 'no x402 charge', and intended for building searchable history. These go beyond the annotations. However, it does not describe behavior on repeated calls or error scenarios, which would be helpful.

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 first two sentences are concise and front-loaded. However, the SAP MCP execution guidance block is repetitive and not directly about the tool's function, adding unnecessary length. Could be more streamlined.

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 tool's simplicity (logging action), the description covers purpose, usage context, and cost. The output schema exists separately. It misses a bit on exact triggers (e.g., should it be called after every call?), but overall adequate.

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?

Schema coverage is 100% with well-described parameters (toolName, outcome, etc.). The description does not add further parameter meaning beyond what the schema provides. Baseline 3 is appropriate as the schema already does the heavy lifting.

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 clearly states it 'Records a tool call execution in the agent memory database (SQLite FTS5)' and specifies the context 'Auto-call after any paid or significant tool call to build searchable history.' This distinguishes it from other memory tools like sap_memory_recall or sap_memory_search, which serve different purposes.

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 advises calling after 'any paid or significant tool call' and notes it is free ('No x402 charge'), giving clear when-to-use guidance. However, it does not explicitly mention when not to use it or compare with alternatives, but the intent is clear for recording.

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