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

With no annotations provided, the description carries full burden. It discloses key behavioral traits: 'smart identifier resolution' that automatically detects identifier types, supports multiple documentation sources, and returns structured data. However, it lacks details on error handling, rate limits, authentication needs, or performance characteristics.

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 and appropriately sized. It starts with a clear purpose statement, follows with supporting capabilities, then provides detailed parameter explanations in a logical Args/Returns format. Every sentence adds value with no redundant information.

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?

Given the tool's moderate complexity (3 parameters, smart resolution logic) and the presence of an output schema (which handles return value documentation), the description is nearly complete. It covers purpose, usage context, parameter semantics thoroughly. The main gap is lack of behavioral details like error cases or limitations, but the output schema reduces this burden.

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 fully compensates by providing comprehensive parameter semantics. It explains 'identifier' with detailed examples and type detection logic, 'topic' with specific use cases and valid values for different identifier types, and 'tokens' with default and minimum values - adding significant meaning beyond the bare schema.

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 as 'get Flutter/Dart documentation with smart identifier resolution' and specifies it supports Flutter classes, Dart classes, and pub.dev packages. It distinguishes from siblings like 'flutter_search' and 'search_flutter_docs' by emphasizing unified resolution rather than search functionality.

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 clear context for when to use this tool (for fetching documentation with identifier resolution) and implies alternatives through sibling tool names like 'search_flutter_docs' for search operations. However, it doesn't explicitly state when not to use this tool or directly compare to alternatives.

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