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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the return format options (string or array of lines) but doesn't cover critical aspects like error handling (e.g., what happens if the file doesn't exist), permissions required, file size limits, or encoding considerations. For a read operation on a remote system, this leaves significant gaps.

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 that front-loads the core purpose and includes a useful detail about return format options. Every word earns its place with zero redundancy or unnecessary elaboration.

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's moderate complexity (reading files from a remote system) and lack of annotations or output schema, the description is minimally adequate. It covers the basic purpose and return format but misses behavioral details like error conditions or security constraints, which are important for remote file operations among many sibling tools.

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 schema description coverage is 100%, so the schema already fully documents all three parameters (server, path, as_lines). The description adds no additional parameter semantics beyond what the schema provides, such as examples of valid paths or implications of the as_lines choice. This meets the baseline for high schema coverage.

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 clearly states the specific action ('Read the contents of a file') and resource ('from the remote system'), distinguishing it from sibling tools like write_file, copy_file, or rename_file. It precisely defines the tool's function without ambiguity.

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 for reading file contents but doesn't explicitly state when to use this tool versus alternatives like get_disk_usage or list_files (if such a tool existed). It provides no guidance on prerequisites, exclusions, or specific contexts beyond the general purpose.

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