get_log_file_by_filename

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP endpoint and the fact that the filename is a path parameter, but it does not add behavioral context like return format or potential size limits. It is consistent with annotations but adds little beyond them.

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 extremely concise and front-loaded with the verb and resource. It contains no fluff or repetition, and the endpoint and argument are presented clearly. It is appropriately sized for a simple read operation.

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?

The tool is simple with one parameter and an output schema, and annotations cover safety. However, the description does not clarify what the output contains (e.g., file content) or any usage considerations (e.g., filename discovery via list_log_file). It is adequate but not thorough for a complete understanding.

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 0%, so the description must compensate. It does mention that filename is a 'Path parameter', which adds a small bit of context beyond the schema's type/title. However, it does not explain what filenames are valid or how they relate to the log file listing, leaving the parameter meaning mostly implicit.

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 the action 'Read LogFile' and provides the endpoint, which clearly indicates it retrieves a specific log file by filename. It distinguishes from siblings like list_log_file and get_log_file_update_by_filename via the filename path parameter. However, it is terse and could be more explicit about returning the file content, so not a perfect 5.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention any context, exclusions, or comparisons to sibling tools such as list_log_file or get_log_file_update_by_filename. The agent receives no routing information.

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