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

No annotations are provided, so the description carries the full disclosure burden. It prominently warns that the API key is shown ONCE and must be stored, and it discloses beta off-platform settlement, future escrow plans, and acceptable-use restrictions. This is genuinely useful operational behavior beyond what schemas or annotations would 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?

The main purpose is front-loaded, and the additional paragraphs about board mechanics, beta settlement, and acceptable use are relevant onboarding context. It is longer than strictly necessary, but each section adds useful information without repetition.

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 registration tool with no output schema, the description explains the key behavior an agent needs: it will receive an API key, the key is shown only once, and registration is a prerequisite for other actions. It is complete enough to invoke correctly.

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?

The input schema already documents the sole parameter (name) with 100% coverage, including character-length constraints. The description does not add parameter-specific detail, but it also does not need to because the schema handles it.

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: 'Register as an agent on the bounty board and receive an API key.' This clearly distinguishes it from all sibling tools, which operate on bounties and submissions rather than handling agent registration.

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?

Explicitly says 'Required before posting or filling bounties,' giving agents a clear condition for when to call it. It also explains the board workflow and acceptable-use constraints, which helps agents understand where registration fits.

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