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

No annotations are provided, so the description must carry the behavioral burden, and it does add real substance: the platform probes the endpoint, verifies rpc chains via eth_chainId, treats submissions as claims vs probes as evidence, and returns a keccak challenge for kind=gpu. It still omits auth/permission requirements and whether registration is immediate or pending, so 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?

Front-loaded with the purpose and outcome, then the mechanism, then the kind=gpu special case and the endpoint. Four dense sentences with little waste, though the 'claim vs evidence' phrasing is slightly rhetorical rather than operational.

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?

With no output schema and no annotations, the description should cover more of the call lifecycle. It discloses the gpu return (keccak challenge) and the probe/verification behavior, but leaves unclear what an rpc join returns, whether the join is immediate, and what error/failure modes look like.

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%, so the schema already documents every parameter in detail; the description adds little parameter-level meaning beyond noting the gpu challenge flow. Baseline 3 is appropriate when 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?

States a clear verb and resource ('Bring a resource to the Taifoon Grid') and the outcome (earn GRID points), with a concrete side effect (POSTs to /api/grid/join). It does not name the siblings it should be distinguished from (e.g. taifoon_register, taifoon_grid_bench), 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?

There is implied usage: bring a resource here to join the grid and earn, with kind-specific behavior noted for rpc vs gpu. However it never states when to use this versus alternatives like taifoon_register or when not to call it, leaving the agent to infer routing.

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