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

Annotations already establish readOnly, idempotent and non-destructive, so the safety profile is covered. The description adds genuinely new context: prices come from 'the same constants Stripe bills' (data provenance/authority), the response deliberately includes what the product does not do, and it clarifies annual is authoritative while monthly is only an explainer.

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?

Content is front-loaded onto the product identity, which is good, but the second sentence is a long run-on enumerating five returned items. Phrases like 'the second product from this team' consume space without helping selection, and the annual-vs-monthly rule is buried at the end.

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, the description carries the burden of describing the return, and it does so specifically: annual price, band inclusions, per-use pricing, deliberate non-capabilities, support line. The optional 'members' parameter's absence behavior is the one meaningful gap.

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 100%, so the single 'members' parameter is fully documented by the schema, including the band-covering behavior. The description only restates the 'for a given community size' framing without adding format, boundary behavior, or what happens when members is omitted despite being optional.

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?

It states a specific resource (governance.center) and what the call yields: the annual price for a community size plus band contents, per-use pricing, exclusions and support line. It partly differentiates from siblings by positioning governance.center as 'the second product from this team', but never names the alternative tools (get_platform_overview, get_price_quote) it must be distinguished from.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no sibling tool is named as the alternative. The closest thing to routing is the passing phrase 'the second product from this team', which is descriptive, not directive. An agent must infer the trigger condition from the return contents.

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