renew_claim

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

Annotations already declare the safety profile (not read-only, idempotent, not destructive), so the description's job is to add nuance — e.g., what happens if the lease has already lapsed, or whether renewal resets the expiry window. It adds none of that; "Extend the lease" merely restates the mutation the annotations already imply.

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 words are not concision here, they are under-specification. There is no wasted sentence, but there is also no front-loaded payload beyond the verb, leaving the definition effectively empty.

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 mutating claim-lifecycle tool with two undocumented required parameters, no output schema, and a crowded sibling set, the description is far too thin. The annotations supply only the basic safety hints; the description never explains lease semantics, failure modes, or how it pairs with claim_task/release_task.

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% and both required parameters (task_id, claim_token) are undocumented. The description says nothing about them — it doesn't explain that claim_token identifies the lease being extended or that task_id scopes it, so an agent gets no help beyond the bare names.

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?

"Extend the lease" gives a specific verb and an object, but the object ("lease") is never tied to the tool's actual resource, a claim on a task. Nothing distinguishes it from siblings like claim_task, release_task, or complete_task, which all operate on the same claim lifecycle.

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?

No when-to-use, when-not-to-use, or alternative is named. An agent must infer from the name alone that this renews an existing claim's lease rather than acquiring (claim_task) or ending (release_task) one.

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