Get multiple files' content

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

Annotations already declare readOnlyHint and idempotentHint, which cover the main behavioral transparency. The description adds implementation details (one itemsbatch request, parallel fetch) that don't contradict or undermine safety, and it explains error reporting for missing files, providing extra clarity.

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 concise and well-structured, using three sentences to convey the batch operation, the process, and the error handling. No redundant information, and it's easy to scan.

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?

For a batch read operation, the description is complete: it specifies what the tool does, how it behaves (including missing file reporting), and refers to the singular tool's diagnostics for consistency. No output schema is needed, and the description provides enough context for an agent to invoke it correctly.

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 100%, with each parameter clearly explained. The main description doesn't add additional meaning beyond the schema, so the baseline score of 3 is appropriate.

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?

Description clearly states it reads several files from one repository at a specific branch/commit/tag in a single call. It differentiates from the singular get_file_content by emphasizing the batch nature, making the tool's purpose unambiguous.

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 implies usage when multiple files need to be fetched simultaneously and contrasts with the singular counterpart via 'in a single call'. It also mentions how missing files are reported, giving practical guidance, though it doesn't explicitly state when not to use it (e.g., for a single file).

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