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

The description discloses the irreversible nature of the 'lock' parameter, which is critical behavioral context. However, it does not mention that this is a build step (no transaction execution) or other side effects, despite no annotations being present.

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 extremely concise: one sentence plus a short note about lock. Every word is purposeful and front-loaded.

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?

The description is minimal for a 6-parameter tool. It does not explain the Metaplex context, that the output is an unsigned transaction, or how it fits into a workflow (build -> execute). Lacks output expectations.

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?

With 100% schema coverage, the description adds no additional meaning beyond what the input schema already provides for parameters. The lock behavior is already described in the schema.

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 the verb 'Build' and the resource 'unsigned set/update Metaplex metadata tx', distinguishing it from sibling tools like 'solknife_token_metadata_execute' and 'solknife_token_metadata_read'.

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 usage for building a transaction, but lacks explicit guidance on when to use this tool versus other build/execute tools in the family. No exclusions or alternatives are mentioned.

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