owner

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

No annotations are provided, so the description carries the full disclosure burden, and it omits permissions, error behavior, and whether the lookup is read-only or blocking. It does, however, disclose a genuinely non-obvious semantic: ownership is reported even when a lease exists on a parent directory, which tells the agent the result accounts for inherited/ancestor state. That single insight is useful but insufficient on its own.

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?

A single short, front-loaded line with zero filler; the scoping nuance is packed into the parenthetical. It is efficient, though arguably too terse to be self-explanatory.

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?

With an output schema present, return values need not be explained, and the tool takes only one required parameter. Still, with no annotations and no usage guidance, an agent lacks context on error cases (e.g., unknown path) and on the relationship to the claim/release siblings, leaving the definition minimally viable.

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%, so the description must compensate; it only refers to 'tuhle cestu' (this path) without specifying format — absolute vs. relative, trailing separator handling, or symlink behavior. The parameter's meaning is guessable from its name but not clarified beyond the 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 reads as a question ('Who holds this path...?') rather than a verb+resource statement, so the operation (query ownership/lease holder) must be inferred. The resource — a path — is named clearly, and the parenthetical distinguishes it from a naive ownership check. It does not name the sibling tools (claim/release) that would make the distinction 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?

There is no guidance on when to call this versus the sibling tools, and no prerequisites or exclusions are stated. The 'even despite a lease on the directory above' clause hints at a resolution rule but not at when an agent should reach for this tool. An agent must infer its role from the name and sibling set.

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