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

Annotations already declare a non-destructive, idempotent mutation. The description adds value beyond them: the cost is 'Free', the deal returns to the shared pool, and the effect is that another scout can claim it. It doesn't cover error cases or required permissions, keeping it short of a 5.

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?

Three tight sentences with no waste. The core action and its semantics are front-loaded, and 'Free' efficiently conveys cost information.

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 one-parameter mutation with no output schema and full annotation coverage, the description supplies the missing operational context (cost, pool destination, counterparty effect). Minor gaps like failure behavior are acceptable at this complexity.

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 100%, and the single dealId parameter is already documented including its source (get_scout_deals). The description adds nothing about parameters, so baseline 3 applies.

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?

States a specific verb (release), resource (a claimed deal), and destination (back to the shared pool). It is clearly the inverse of the sibling claim_deal, and the parenthetical clarifies what 'release' means operationally.

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?

Gives an explicit when-to-use trigger: 'when the user skips a deal they claimed, so another scout can take it.' This is clear context, though it doesn't explicitly name claim_deal as the complementary action or state when NOT to use it.

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