Who owns a path

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

The description indicates it returns the owner and whether the user can proceed, which are behavioral traits. However, it lacks details such as what happens if the path does not exist, whether it performs any side effects, or any authentication requirements. With no annotations, the description carries full burden and is somewhat minimal.

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 concise sentence that front-loads the purpose and outcome. Every word adds value, with no 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?

For a simple read-only tool with one parameter and no output schema, the description covers the essential purpose and return values. It could mention edge cases like non-existent paths, but overall it is sufficiently complete for an agent to understand when and how to use it.

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 one parameter 'path' with 100% description coverage, including an example. The tool description does not add extra parameter information beyond what the schema already provides, so it meets the baseline but does not enhance understanding.

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 explicitly states the tool's purpose: checking if a path belongs to another dev's scope before editing. The verb 'check' and resource 'ownership' are specific, and the tool is clearly distinct from sibling tools like 'broadcast' or 'remember'.

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 clear usage guidance: use this tool before editing a file or directory. It implies when to use it, but does not explicitly state when not to use it or mention alternatives. Given the simple context, this is adequate.

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