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

Annotations indicate readOnlyHint=false and destructiveHint=false, consistent with a non-destructive update. However, the description does not clarify the exact update behavior (e.g., full replacement vs. merge) or what happens to existing fields. It focuses on access prerequisites rather than the tool's internal operation. With annotations providing safety cues, a score of 3 reflects partial but not complete transparency.

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 well-structured: it starts with the core purpose, then provides usage guidelines in a clear, step-by-step manner. It is not overly verbose; each sentence contributes information. A minor issue is that the interchangeable note could be more seamlessly integrated, but overall it is concise 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?

The tool has no output schema, and the description does not mention return values, confirmation, or any post-update behavior. The parameter semantics are incomplete, and there is no guidance on error handling or success indicators. For an update tool with no output schema, the description should at least hint at what the agent can expect as a result, but it does not. This limits the agent's ability to understand the full context of using the tool.

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?

With 0% schema description coverage, the description must add meaning to the parameters. It only clarifies that communityId can be a business or community ID (via the interchangeable note). It does not explain the 'applicationConfigDataFields' array structure or what objects it should contain. The description adds minimal value beyond parameter names, leaving agents unclear on how to format inputs.

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's purpose: 'Update application form fields for a managed community.' It explicitly clarifies that 'Business and community refer to the same thing and are interchangeable,' which resolves potential ambiguity with the tool name and distinguishes it from similar tools like 'update_community_application_config.' The verb 'update' is specific, and the resource is well-defined.

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 guidance: it instructs to check permissions before offering the tool, notes that 'FREE businesses cannot use this tool,' and specifies to 'call check_business_tool_access before collecting inputs.' It also details required actions like showing grace-period warnings and never proceeding when access is blocked. This is comprehensive and leaves no ambiguity about prerequisites.

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