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

Annotations indicate mutation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds behavioral context: it requires permission checks, blocks free businesses, and involves a grace-period warning and resubscribe link. It does not detail failure modes or side effects, but the added context is valuable beyond annotations.

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 moderately concise, starting with the main action and then providing procedural guidelines. The phrase 'Business and community refer to the same thing and are interchangeable' is slightly redundant and could be condensed, but overall each sentence adds value.

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?

The description covers prerequisites and workflow steps, but lacks parameter descriptions and does not explain return values or post-update effects. For a mutation tool with 3 parameters and no output schema, this leaves gaps for the agent to infer meaning.

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% with 3 parameters (communityId, triggerName, notificationEnabled). The description provides no explanation of these parameters—what they represent, valid values, or how they relate to the action. For a tool with low schema coverage, the description should compensate, but it fails to do so.

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 it updates notification preference for a community trigger, and clarifies the interchangeability of 'business' and 'community' to avoid confusion. However, the title says 'Business Notification Preference' while the tool name is 'community', causing a slight mismatch. It distinguishes from siblings like 'update_business_notification_preference' but the interchangeable statement may blur uniqueness.

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?

Excellent guidance: specifies prerequisites (check business permissions, call check_business_tool_access), restrictions (FREE businesses cannot use), and required UI steps (show grace-period warning and verified resubscribe link). It explicitly tells when not to proceed, providing strong decision support for the agent.

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