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

Annotations already indicate openWorldHint=false and destructiveHint=false, so the safety profile is partially covered. The description adds meaningful behavioral context by explaining that publishing changes which version datafiles resolve to when binding without requesting the latest, which is the key state-changing effect beyond what annotations convey.

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, well-structured sentence that leads with the action and resource, then explains the meaningful consequence. Every word earns its place, with no redundancy or filler.

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?

For a simple two-parameter tool with a full input schema and an output schema, the description covers the essential behavior and side effect. It could be more complete by noting that the version must already exist or by clarifying reversibility, but those are not critical gaps given the available structured information.

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?

Input schema coverage is 100%, with both schema_id and version having explicit descriptions. The tool description adds no parameter-specific details beyond what the schema already provides, so the baseline score of 3 applies.

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 'Publish' and the resource 'a schema version,' then defines the precise effect: making that version the default resolution for datafiles that bind to the schema without requesting the latest. This distinguishes it from other publish_* sibling tools and from create_schema_version, which creates rather than publishes.

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 when to use this tool through its explanation of default resolution behavior, but it does not explicitly state when to use it versus alternatives such as create_schema_version or update_schema. There is no when-not-to-use guidance or mention of prerequisites like the version already existing.

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