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

The description adds significant behavioral context beyond annotations: it requires pre-checks, warns against use for free businesses, and mandates showing warnings. However, it does not describe the post-claim state (e.g., what changes occur in the system, any return values), which would be beneficial. Annotations already indicate a non-read-only, non-destructive mutation, and the description aligns.

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 four sentences long, each adding value. It front-loads the purpose, then details prerequisites and constraints. It is efficient but could be slightly more concise by removing redundant phrasing like 'Business and community refer to the same thing and are interchangeable,' which is only helpful for disambiguation.

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 tool with one parameter and no output schema, the description covers prerequisites, permission checks, and conditional warnings. It lacks information about the tool's return value or side effects (e.g., does it modify plan status?), but given the focus on preconditions, it is fairly complete. The annotations provide basic behavioral hints.

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?

The input schema has one required parameter 'communityId' (string) with no schema description. The description does not elaborate on the parameter's meaning, format, or constraints beyond what is implied by the name. With 0% schema coverage, the description could have added value but did not. However, the parameter is self-explanatory, and the purpose is clear, so a baseline score of 3 is appropriate.

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 tool claims a community plan benefit. It mentions interchangeability between business and community, but does not explicitly differentiate from the sibling 'claim_business_plan' tool, which likely has an analogous purpose. The verb 'claim' and resource 'community plan benefit' are specific.

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 provides explicit when-to-use instructions: check business permissions, call check_business_tool_access before collecting inputs, show grace-period warnings, and never proceed when access is blocked. It also states a clear exclusion: 'FREE businesses cannot use this tool, regardless of individual feature rows.' This surpasses minimal guidance.

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