get_read_file

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. However, the description adds no extra context beyond the annotations, such as error behavior, permission requirements, or what 'read file' specifically means. It contributes minimal value beyond the structured metadata.

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 ('Get single file') but this is under-specification rather than genuine conciseness. It omits crucial context about the file type and use cases, so the brevity is not justified by completeness.

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?

With no output schema and a single parameter, the tool is simple, but the description is insufficient for an agent to distinguish it from many file-related siblings. The lack of usage guidance and the ambiguity around 'read file' make the overall context incomplete.

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% and the parameter 'file_id' is described as 'File ID to show', which is clear. The description 'Get single file' adds slight clarity that only one file is retrieved, but it does not provide additional semantic detail beyond the schema.

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 single file' clearly indicates a read operation but lacks specificity about what a 'read file' is, especially with sibling tools like 'get_file' and 'list_read_files'. It does not distinguish itself from the generic 'get_file', making the purpose ambiguous despite a clear verb and resource.

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 'get_file', 'download_file', or 'list_read_files'. The description gives no context for selection, failing to clarify which file type is meant or when to prefer this over siblings.

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