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

No annotations are provided, so the description must bear full burden. It only states that the tool 'explains', but the input schema implies it scans files (via projectPath and limit). This behavioral trait (file scanning) is not disclosed, and no side effects or permissions are mentioned, leading to low 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 extremely concise, consisting of a single sentence that front-loads the purpose. Every word serves a function. However, it could be slightly expanded to include behavioral context without becoming verbose, so it is not perfect but reasonably concise.

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?

Without an output schema and with minimal description, the tool's behavior is underspecified. The description does not explain how the tool uses the input parameters, what the output looks like, or what 'scanning' entails. For a tool targeting beginners, this lack of context significantly reduces completeness.

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 description adds no meaning beyond the input schema. While schema coverage is 67% (two parameters have descriptions), the description does not clarify the purpose of projectPath or how the parameters relate to the explanation process. The goal and limit descriptions are already in the schema, so the description adds no value.

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 what the tool does: explain the complete engineering process of a mini-app from requirements to launch. It uses specific verbs ('解释' meaning explain) and resources ('完整工程流程' meaning complete engineering process), differentiating it from sibling tools that focus on specific aspects like feature impact or file roles.

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 no guidance on when to use this tool versus alternatives. With many sibling tools (e.g., miniapp_understand_feature_impact, miniapp_work_breakdown), explicit usage context is missing, leaving the agent to guess based solely on the name and description.

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