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

Annotations already declare a non-destructive mutation (readOnlyHint=false, destructiveHint=false). The description adds meaningful obligation context, that the operator commits to registering the capability and completing verification, but it doesn't state whether the claim is exclusive, what happens on failure to complete, or what the response signals.

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 short sentences with the action front-loaded and the commitment detail second. No wasted text, though it could arguably say more given the surrounding ecosystem.

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 mutation tool with no output schema, the description covers what it does and the operator's obligation but omits prerequisites (bounty availability, how to find bountyId via list_bounties) and post-claim state. Annotations cover the safety profile, so this is adequate rather than complete.

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%, with both bountyId and operatorId clearly documented, so the schema carries the weight. The description adds no format, ID-source, or constraint detail beyond the schema, making the baseline 3 appropriate.

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+resource ('claim a bounty') and adds purpose ('to onboard a new capability'), which distinguishes it from read-side siblings like list_bounties. It doesn't explicitly contrast itself with verify_bounty or convert_bounty_to_pool, so it stops short of full sibling differentiation.

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?

Usage is implied by the stated goal of onboarding a capability, but there is no explicit when-to-use or when-not-to-use guidance, and no prerequisite (e.g. that the bounty must be listed/available, or how this relates to verify_bounty). The agent must infer the trigger conditions.

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