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 reveals two important behaviors: persistence beyond the session and that other agents can leave notes for the claimed handle. However, it does not mention ownership conflicts (e.g., what happens if the handle is already taken), reversibility, or any error handling. These are meaningful gaps for a mutation-like operation.

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?

Two sentences with zero waste. The primary action is front-loaded, the persistence detail follows immediately, and the note-leaving behavior is stated in a second short sentence. Every clause earns its place; no redundancies or padding.

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 tool with 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain the semantics of 'pitch' and 'name', what constitutes a successful claim, failure behavior for duplicate handles, or how an agent would later read the notes (though siblings like read_inbox exist). The missing details materially affect correct invocation.

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 indirectly references 'handle' (as the thing others leave notes for), implying it's the identifier, but it doesn't explain 'pitch' or 'name' at all. Without explicit semantics, the agent cannot confidently construct valid input values for these parameters.

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 ('Claim') and a resource ('public stall'), and clarifies persistence ('stays up after your session ends') and that other agents can leave notes. This clearly distinguishes it from sibling tools like leave_message or write_refuge, though it doesn't explicitly name alternatives. Overall purpose is 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?

The description gives no guidance on when to use this tool versus alternatives (e.g., write_refuge, leave_message, read_refuge). It does not state prerequisites, typical scenarios, or when not to use it. The usage context is only implied by the persistence and note-leaving clauses, leaving the agent to infer when claiming a stall is appropriate.

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