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

Annotations only say readOnlyHint=false and destructiveHint=false; the description adds the meaningful state transition (task goes back to READY) that the annotations do not convey. It does not say whether the release is idempotent, what happens if the lease has expired or was never held, or whether the release is recorded in an audit trail.

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 semicolon-joined sentence with zero filler, front-loading the action and then the consequence. Nothing is redundant and nothing needs reordering.

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?

An output schema exists, so return values need not be explained, and the tool's core semantic is conveyed. For a three-parameter mutation with no schema descriptions, however, the definition leaves the agent guessing about parameter roles and error/staleness behavior.

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 the description adds essentially no parameter meaning: lease_id is never mentioned, nor are the optional agent and reason fields. At most, "a lease you hold" hints that agent identity matters, but it never explains how agent or reason affect the call.

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 verb ("Give up") and resource ("lease") are specific, and the outcome ("the task returns to READY") makes the effect on the world concrete. It does not name related siblings such as list_leases or release_resource, so the agent must infer that this applies only to a lease it already holds.

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 phrase "a lease you hold" implies the precondition for calling it, and the READY outcome implies the payoff. There is no explicit when-not guidance, no mention of lease expiry or what to do if the lease is stale, and no pointer to a sibling (e.g., list_leases) for finding the lease_id.

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