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

Annotations indicate non-read-only and non-destructive behavior, which aligns with 'Send a notification.' The description adds procedural context (permission checks, warnings) but does not disclose other behavioral traits such as side effects, idempotency, or what happens upon success/failure.

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 concise with 4 sentences, each serving a purpose. The first sentence defines the action, and the rest provide essential usage steps. It could be slightly improved by structuring the guidelines as bullet points, but it remains efficient and front-loaded.

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?

Given the tool has 3 parameters with no schema descriptions and no output schema, the description leaves critical gaps: no explanation of parameter meanings, no mention of return values, and no clarification of what a 'unified product change log' is or how to obtain identifiers. The tool's operation and expected results are under-specified.

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 0% description coverage, and the tool description does not explain the parameters (changeLogId, communityId, notifyMessage). Only communityId and changeLogId are vaguely implied by the purpose statement, but no details on what they represent or how to obtain them.

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 sends a notification for a unified product change log in a managed community, providing a specific verb and resource. However, it does not explicitly differentiate from sibling notification tools like send_community_mail or send_magic_reach_message, missing an opportunity to highlight 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?

The description provides explicit prerequisites: check business permissions, call check_business_tool_access, show grace-period warnings, and never proceed if blocked. It also states that FREE businesses cannot use this tool. This context helps determine when to use the tool, but it does not mention alternative tools for other notification types.

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