post_fs_cat

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

The description lacks any behavioral context beyond a list of error codes. No annotations are provided, and the description does not disclose side effects, permissions, or other behavioral traits.

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 sparse, consisting solely of an error code list. While it is short, it does not achieve conciseness; it omits essential information about the tool's function.

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 complexity (a POST operation likely interacting with filesystem) and lack of output schema details, the description is completely inadequate. An agent cannot determine how to invoke or interpret the 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?

Although there are no parameters, the description does not add any meaning beyond the empty input schema. It fails to clarify that no input is required or what the tool expects.

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 only lists error codes and does not state what the tool does. It fails to provide a verb or resource, making it impossible for an agent to understand the tool's purpose.

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 guidance on when to use this tool versus alternatives. The sibling list includes similar post_fs tools (cp, mv, rm), but no differentiation is provided.

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