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

No annotations are provided, so the description carries the full burden. It states the tool builds an unsigned transaction and returns specific data, implying no state change. However, it does not disclose requirements (e.g., payer must hold SOL), error conditions, or idempotency. The description is accurate but not rich.

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 sentence that is concise and front-loaded with the key purpose. It could be slightly more structured (e.g., listing return values explicitly), but there is no wasted information.

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 an output schema, the description does explain the return values (base64 tx, lastValidBlockHeight, mint address). However, it does not elaborate on how nested parameters like 'extensions' affect the build, which might be needed for full understanding.

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 high (83% with 5 of 6 parameters described), so the baseline is 3. The tool description does not add any extra meaning beyond what the schema already provides for parameters like 'extensions' or 'freezeAuthority'. It is adequate but not enhanced.

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 specifies the action ('Build an unsigned create-mint tx'), the resource ('create-mint'), and the output ('base64 v0 transaction + lastValidBlockHeight + derived mint address'). It distinguishes from sibling tools like solknife_create_mint_execute by noting it builds an unsigned transaction.

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 does not provide guidance on when to use this tool versus alternatives (e.g., solknife_create_mint_execute). It does not mention that the returned transaction needs to be signed and broadcast, or that this is a preparation step before execution.

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