Update Call Log

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

Discloses partial update behavior ('only the supplied fields are changed') and return value ('returns the modified object on success'). Annotations already indicate readOnlyHint=false and destructiveHint=false; description adds valuable context about partial updates.

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?

Description is concise with four sentences plus a link and endpoint. Information is front-loaded. The link adds value for attachments but slightly increases length.

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?

Covers core purpose, partial update, required parameters, and return value. No output schema, so return description is sufficient. Lacks error handling details but acceptable for a tool with moderate complexity.

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 clear parameter descriptions. Description repeats required parameters but adds no new meaning beyond schema. The partial update hint is already covered in behavioral transparency.

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?

Clearly states 'Update single Call Log' with a specific verb and resource. Differentiates from sibling tools like create_call_log, delete_call_log, list_call_logs by focusing on updating an existing record.

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?

Provides context ('Use this to update an existing Daily Log records') but does not explicitly exclude creation, deletion, or other operations. No mention of when not to use this tool or alternatives.

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