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

No annotations are provided, so the description carries the full burden. It does disclose that behavior is XML-defined and cannot be inferred from C#—a valuable insight. However, it doesn't state whether the tool reads or writes, what side effects occur, or what output to expect. This ambiguity is significant for a tool with 'customizations' in its scope.

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 two sentences: the first lists the tool's scope compactly, the second provides a crucial caveat. It is front-loaded with the domain and keeps the warning high-priority. No wasted words or redundant structure.

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?

This tool operates in a complex domain (XAF model customization) with no output schema and no annotations. The description tells you what the tool covers but not what it returns, whether it mutates state, or how it relates to the many sibling tools. The XML caveat is helpful but insufficient for confident use.

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 only parameter 'project' is already fully described in the schema ('Project name, when several are configured.'). Since schema coverage is 100%, the description adds no new semantic value, and the baseline of 3 applies. No extra usage details are given for the parameter.

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 identifies the resource (Model Editor .xafml customizations) and enumerates specific content areas (captions, list/detail views, columns, filters, app options). However, the verb is implicit ('customizations' rather than 'get' or 'edit'), so it doesn't crisply state the action. It does distinguish itself from sibling tools by focusing on .xafml model behavior.

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 'IMPORTANT' statement gives a clear directive: check this tool before concluding how a screen behaves because behavior exists in XML, not C#. This implies when to use it, but it doesn't explicitly name alternatives or exclusions. Still, the usage context is strong enough to guide an agent.

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