get_file_content

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

With no annotations, the description must reveal behavioral traits. It only says 'Get...metadata', not clarifying if it's read-only, what permissions are needed, or what the response contains. No output schema further limits transparency.

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 short at five words, which is concise but at the cost of essential details. It is not optimally informative for an agent to invoke correctly.

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 the tool has four parameters with no descriptions and no output schema, the description is woefully incomplete. It does not explain return values, error cases, or the role of the 'ref' parameter, leaving significant gaps.

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%—no parameter descriptions exist. The description adds no information about the four parameters (owner, repo, path, ref), failing to compensate for the lack of schema documentation.

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 'Get repository file content metadata' indicates the tool retrieves something related to file content, but 'metadata' is ambiguous—it could mean actual content or attributes. Compared to siblings like 'create_or_update_file' and 'list_repository_files', the purpose is somewhat clear but not precise.

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 such as 'list_repository_files' or 'get_commit'. There is no mention of prerequisites, context, or exclusions.

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