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

With no annotations provided, the description carries the transparency burden. It does disclose a key behavioral trait—that the lists are exhaustive and authoritative—which is valuable. However, it does not mention other behavioral aspects such as performance implications, response format, or whether it reads from a cache or scans files, leaving some transparency gaps.

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 concise sentences. The first sentence encapsulates the tool's content, and the second provides usage and behavioral guidance. There is no redundant or filler text, making it well-structured and efficient.

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 an overview tool with no output schema, the description provides a solid sense of what the response will contain (complete lists of key components). It stops short of detailing the exact result format or organization, but the content scope is clear enough for the agent to infer what to expect.

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 fully documents the single 'project' parameter with a clear description, so schema coverage is 100%. The tool description adds no additional parameter semantics, so it does not go beyond the schema baseline.

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 defines the tool as an overview of the entire XAF application, listing ORM, module setup, and exhaustive enumerations of entities, controllers, actions, and navigation groups. It distinguishes itself from sibling tools by emphasizing it is the complete index and should be called first for whole-app questions.

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?

Explicitly states 'Call this first when asked anything about the application as a whole', giving a direct usage trigger. It also implies the tool serves as a definitive existence check ('if something is not in them, it does not exist'), which guides when to rely on its results versus diving into specific sibling tools.

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