read_file

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

No annotations provided; the description only states 'Read file content' and 'Returns: File content and metadata'. Does not disclose important behaviors like supported file types, size limits, or that it is read-only.

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?

Concise with clear Args and Returns sections. However, it could include more behavioral details without increasing length significantly.

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?

Covers basic purpose and parameter, but lacks details like return format (plain text?) and behavioral constraints. Moderate completeness given no output schema and simple tool.

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 has 0% coverage (path is just 'string' with no description). The description adds 'File path (relative to data directory)', providing essential context 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?

Description states 'Read file content' which clearly identifies the action and resource. It distinguishes itself from siblings like list_directory and search_files, but is somewhat tautological with the tool name.

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 on when to use this tool versus alternatives. Does not mention exclusions or prerequisites, such as file existence or permissions.

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