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

The annotations already communicate read-only, idempotent, non-destructive behavior, so less description is needed. The phrase 'supported' adds a hint of availability filtering and the response contents are useful, but the description does not disclose error cases, operational constraints, or required auth context.

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?

One sentence with no filler, front-loaded with the core action and resource, then a compact enumeration of return contents. Every word earns its place.

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?

With no output schema and a nested audit parameter, the description is too thin. It does not clarify the taxYear values, the meaning of 'supported,' the audit fields, or how to choose among the sibling tools, leaving a nontrivial operation underspecified.

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 0%, so the description needs to compensate. It mentions Form BE or Form B, which maps to formType, but it does not explain the taxYear parameter, the audit object, or how they affect the release being returned.

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 uses a specific verb, 'Return,' and names the resource as a supported Form BE or Form B release, while also listing what is included: official sources, validation result, review status, and known limitations. It is clear on its own, but it does not explicitly contrast itself with sibling list/search tools.

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?

No usage guidance is provided. The description does not say when to use this tool instead of list_tax_authority_releases, search_tax_authority, or the preparation/assessment siblings, and it lacks any prerequisites, exclusions, or selection criteria.

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