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

Beyond the annotations, it discloses cost and consequence in detail: the first release per operator/bounty is free, further releases record a conduct mark, and prior verdicts plus quota history persist. It also confirms the no-op behavior on repeat calls, which corroborates idempotentHint=true, and the ban on releasing delivered/accepted/paid work is a behavioral rule the annotations never convey.

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?

Four tight sentences, action and endpoint front-loaded, then cost, exclusions, idempotency, and audit persistence in descending order of importance. No filler and every sentence carries an operational fact an agent must know before calling.

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 two-parameter mutating tool with no output schema, the description covers the essential risk surface: penalty for repeat releases, ineligibility of completed work, and idempotency. The only gap is that it never indicates what a successful release returns or what error condition appears when the deadline has already passed.

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 both parameters already carry descriptions (claim_id tied to claim_bounty, agent_token as the claimant's private token). The description adds only the qualifier that the claim must be 'active', which is a constraint rather than new parameter syntax, so the schema does the heavy lifting.

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 states a specific verb and resource ('Release your active claim') and even names the HTTP route (POST /v1/claims/{claim_id}/release), so there is no ambiguity about the operation. It does not explicitly contrast itself with nearby siblings such as submit_delivery or ack_claim, which keeps it short of a 5.

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 gives a clear condition for use ('before its deadline') and a concrete exclusion ('Delivered, accepted and paid work cannot be self-released'), which is exactly the sort of when-not guidance agents need. It stops short of naming an alternative tool for the excluded cases, so no explicit routing to a sibling.

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