reclaim_name

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

With no annotations, the description carries the full burden. It discloses the core behavior (syncing registry owner to match token owner), the caller requirement, and the potential need to set resolver afterward. It does not mention reversibility, fees, or edge-case failures, but covers the most important behavioral traits.

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 description is well-structured: a clear one-line purpose, a bulleted list of use cases, and a short prerequisite/follow-up note. Every sentence adds value, with no redundancy or fluff. Despite being more than one sentence, it is appropriately sized for the tool's complexity.

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?

Given the absence of an output schema and annotations, the description provides sufficient context for an agent to know when to use the tool, what it does, and prerequisites. It doesn't explain return values or error conditions, but those aren't critical for a mutation tool of this simplicity. The description is adequate, though a note about on-chain effects would elevate it.

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 have clear descriptions already. The description adds context by explaining the relationship between the parameters (owner must own the BaseRegistrar token) and the purpose of the 'name' parameter, but does not introduce new semantics beyond what the schema provides. Baseline 3 is 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 opens with a specific verb+resource: 'Reclaim ENS Registry ownership of a .eth name.' It clearly distinguishes this from sibling tools like transfer_ens_name or set_resolver by focusing on the sync between ENS Registry and BaseRegistrar token ownership. The use cases further clarify exactly what it does.

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?

Explicit 'Used when' list enumerates three specific scenarios, making it clear when to invoke this tool. It also states a prerequisite (caller must own the BaseRegistrar ERC-721 token) and a follow-up action (may need to set resolver). This provides strong guidance compared to alternatives.

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