flutter_widget_lookup

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

No annotations were provided, so the description carries the burden of behavioral disclosure. It describes the tool as read-only search/return behavior, which is apparent from the verb 'Search' and 'Returns'. It doesn't disclose what the return payload looks like, whether results are ranked, or whether the catalog is well-maintained, but for a simple read tool the behavior is adequately implied.

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?

Very concise single sentence that states purpose and output in compact form. No wasted words. Could arguably break out what's returned as a separate element, but the single sentence is efficient and front-loaded with the primary verb and resource.

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 a two-parameter, no-output-schema tool, the description covers the basics: what it does and what it returns. However, given 14 sibling Dart/Flutter tools, some differentiation or usage guidance would improve completeness. The output shape (prop list, code snippets) is only vaguely referenced by 'properties, usage tips, and best practices'.

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?

Schema coverage is 100%, so both parameters (query, category) are documented in the schema. The description adds modest value by framing the tool as returning 'properties, usage tips, and best practices' but doesn't describe how 'category' interacts with 'query' or whether category is optional/required filtering. The schema already handles parameter documentation, placing this at 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?

Clear verb+resource: 'Search the curated Flutter widget catalog.' It states what it returns (widget properties, usage tips, best practices). It doesn't explicitly differentiate from siblings, but the 'widget catalog' focus is reasonably distinct from other Flutter tools like flutter_docs or flutter_knowledge.

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?

No explicit when-to-use or scenarios are given. Among 14 sibling Flutter tools (flutter_docs, flutter_knowledge, flutter_source_search, etc.), there is no guidance on when to prefer this tool over alternatives. The closest indicator is the word 'curated' suggesting it's for curated knowledge, but this is not explicit.

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