Update Weather Log

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

Annotations already indicate a write operation, and the description adds that only supplied fields are changed (partial update). It does not disclose side effects, auth requirements, or rate limits, but the annotations cover the basic safety profile.

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 somewhat verbose with documentation links and endpoint details, but it is structured with a clear purpose first. It could be more concise without losing clarity.

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 no output schema, the description states it returns the modified object. It covers required parameters but does not explain the nested 'weather_log' object shape, though the schema covers that. Adequate but not fully comprehensive.

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%, so baseline is 3. The description adds no additional meaning beyond what the schema already provides, only listing required parameters and referencing external docs for attachments.

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 updates a single Weather Log, distinguishing it from create/delete siblings. It uses specific verb+resource, though extra endpoint info could be streamlined.

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 says 'Use this to update an existing Daily Log records' and lists required parameters, implying usage context. However, it does not provide when-not-to-use or mention alternatives, leaving some ambiguity.

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