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

With no annotations, the description carries the full burden and does disclose the key behaviors: the authorization requirement ('claimant or host only') and the resulting state change (bounty returns to open, available for others). It omits failure modes (e.g., behavior for non-claimants) and whether re-claiming is immediate, so it is not exhaustive.

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 tight sentences with the action and state effect front-loaded, then the usage trigger. No filler or redundancy.

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 single-parameter state-transition tool with no output schema, an agent has what it needs: what happens, who may call it, and when to call it. Only parameter sourcing/format guidance is missing.

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 should compensate, but it only alludes to 'a bounty' without giving the ID format or where to obtain it. The single parameter's name (bounty_id) is self-evident, which keeps this at a minimum-viable 3 rather than lower.

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 and resource ('release your claim on a bounty') plus the resulting state ('back to open'), which is enough to separate it from claim_bounty and set_bounty_status. The parenthetical scope note adds precision without ambiguity.

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?

'Use when you can't finish the work — someone else can pick it up' gives a clear triggering condition and motivation. It does not name explicit alternatives (e.g., set_bounty_status) or when-not-to-use, so it stops short of a 5.

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