is_under_maturity_period

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

With no annotations, the description carries the full burden for behavioral disclosure. It only says 'Check', implying a read-only operation, but it does not specify return type, error behavior, side effects, or anything about the maturity period semantics. This is a minimal disclosure, similar to the update_drive example.

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 a single, front-loaded sentence that states the purpose without any fluff. Every word is necessary. It is appropriately sized for a simple predicate tool.

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 lack of annotations and output schema, the description is incomplete. It does not explain what the tool returns (e.g., a boolean), how maturity period is determined, or what happens for invalid token IDs. The context of 'maturity period' is left undefined, which could be confusing without sibling tool context.

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 schema has 100% description coverage for the single parameter (tokenId). The tool description adds no additional meaning beyond what the schema already provides ('Token ID to check if under maturity period'), so it lands at the baseline of 3. No new format, constraints, or nuances are introduced.

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 clearly states a specific action ('Check') on a specific resource ('StarGate NFT') with a specific condition ('still under maturity period'). However, it does not distinguish itself from sibling tools like get_maturity_end_block or can_transfer_stargate_nft, so it loses a point for not differentiating.

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?

The description implies its usage (when you need to know maturity status), but it provides no explicit guidance on when to use this tool versus alternatives such as get_maturity_end_block or can_transfer_stargate_nft. There are no exclusions or alternative mentions, so it only meets the 'implied usage' bar.

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