claim_clink

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

With no annotations provided, the description carries the burden of behavioral disclosure. It reveals the key behavioral trait: claiming locks the clink against other workers and expires after a default timeout. It does not describe what happens if a clink is already claimed, but the core safety semantics are well covered.

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 two concise sentences, front-loaded with the action and purpose, with no filler. The timeout and expiry details are valuable and compactly stated.

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 claim tool with two parameters and no output schema, the description covers purpose, exclusivity, and expiry, which are the essential aspects. It lacks explicit conflict/error semantics (e.g., what happens if the clink is already claimed), but overall it is sufficient for an agent to decide to invoke 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?

Schema coverage is 100%, and the timeout_seconds parameter already includes its default in the schema. The description only restates the default 5-minute timeout, adding no new parameter-level meaning, so the baseline score of 3 is appropriate.

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 uses a specific verb 'claim' with the resource 'clink' and clearly explains the purpose: to indicate processing and prevent concurrent processing by other workers. It distinguishes this from sibling tools like complete_clink and release_clink by focusing on the initial locking action.

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?

It explicitly states when to use the tool (before processing) and notes the expiry and release behavior, giving clear operational context. However, it does not directly name alternatives like release_clink or complete_clink or state when not to use it, so it falls just short of full alternative guidance.

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