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 never says whether this is a read-only analysis or something that mutates state, whether it can fail, or what a verdict contains beyond the fact that it 'names its stack'. One useful hint is given (the verdict echoes the stack), but the behavioral profile remains largely opaque.

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?

A single colon-fronted sentence with no filler, and the core operation lands in the first few words. The compressed jargon in the opening phrase slightly slows comprehension but nothing is wasted.

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 two-parameter tool with an untyped nested object, no annotations, and no output schema, the description should say more about what a verdict contains and how the omitted-stack case behaves. As written, an agent still has to guess at the tool object's contract and the result format.

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 coverage is 0% and one parameter is an untyped nested object, so the description must compensate. It clarifies that 'tool' is a single submitted tool definition and that 'stack' refers to a curated reference stack, but it never explains the shape of the tool object or whether 'stack' is optional (the schema marks only 'tool' required).

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 states a specific verb and resource ('measure one submitted tool against the curated reference stacks') and names the artifact produced ('verdict'). The prefix 'server-author pre-publish verdict' is jargon-heavy but the clause after the colon makes the operation unambiguous, and no sibling tool in the list does measurement-of-a-tool.

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 word 'pre-publish' implicitly tells the agent this belongs to the go/no-go phase before publishing a tool, which is real usage context. However, it names no alternative (unlike apply_fix or register_catalog) and states no prerequisites or when-not-to-use conditions.

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