read_file

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

With no annotations, the description carries the full behavioral burden and does not meet it. It does not disclose whether reads require permissions, how large or binary files are handled, whether the file must exist, or what errors look like on missing/inaccessible paths.

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 single sentence is front-loaded and wastes no words, but its brevity comes from under-specification rather than efficient communication. It is neither bloated nor helpful beyond the tool title.

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?

An output schema exists, so return values need not be explained, but for a file-reading tool the description still omits critical context: path resolution rules, size/encoding limits, and failure modes. It is too thin to guide correct invocation on its own.

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 description coverage is 0% and there is a single required parameter, file_path, whose meaning the description never elaborates. It does not clarify path format (absolute/relative), root/workspace constraints, or encoding, so it adds nothing beyond the bare 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 states a specific verb ('Read') and resource ('contents of a file'), so the core operation is unambiguous. It does not, however, differentiate from any sibling or indicate scope (single file, local vs remote path namespace).

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?

There is no indication of when to use this tool, when not to, or what alternatives exist. Given the large sibling list, some routing guidance (e.g. versus a file-listing or search tool) would be valuable, but none is offered.

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