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

Annotations provide readOnlyHint=false, but the description doesn't add meaningful behavioral context beyond the basic action. It doesn't mention whether it displays the entire file, handles binary files, shows errors for missing files, or has any output formatting. With minimal annotations, the description carries most of the burden but provides limited behavioral insight.

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 a single, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it immediately scannable and perfectly concise for this simple tool.

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 file content display tool with no output schema and minimal annotations, the description is insufficient. It doesn't explain what format the content is displayed in (raw text, encoded, etc.), whether it handles large files, or what happens on errors. The context signals indicate a simple parameter structure, but the description lacks completeness for practical use.

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?

The input schema has 100% description coverage with a clear 'file' parameter documented as 'File path'. The description adds no additional parameter semantics beyond what's in the schema, so it meets the baseline of 3 for high schema coverage without extra value.

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 'Display content of a file' clearly states the verb ('display') and resource ('content of a file'), making the purpose immediately understandable. It doesn't explicitly differentiate from siblings like 'head' or 'tail', but the core function is 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 provides no guidance on when to use this tool versus alternatives like 'head', 'tail', or 'grep' from the sibling list. It states what the tool does but offers no context about appropriate use cases or limitations.

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