get_log_file_update_by_filename

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, so the safety profile is covered. The description adds no further behavioral context such as file content format, error behavior, or special constraints, merely restating that it reads the resource.

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 very short and front-loaded with the core statement, followed by the endpoint and argument. It avoids waste, though a single additional sentence about usage or filename format would improve it without bloat.

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?

Despite being a simple one-parameter read with an output schema and safety annotations, the description leaves critical ambiguity: what exactly 'UpdateLogFile' is, what filename to supply, and how it differs from the similar sibling get_log_file_by_filename. This is insufficient for confident selection and invocation among many sibling tools.

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 description coverage is 0%, so the description must compensate. It only says 'filename: Path parameter,' which tells the agent the parameter goes in the URL path but not what filename values are valid, whether an extension is needed, or how it maps to the update log.

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 a clear verb and resource: 'Read UpdateLogFile.' The endpoint confirms it is a GET operation for a specific log file. However, it does not explicitly distinguish this from the closely related sibling get_log_file_by_filename, leaving the 'update' qualifier in the name as the only differentiator.

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?

There is no guidance about when to use this tool versus alternatives like get_log_file_by_filename or list_log_file_update. The endpoint path hints at the update log, but no explicit context, exclusions, or selection criteria are provided.

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