find_component

Semantically search for web components by name, description, or member names. Returns top 3 matches with scores above zero.

Instructions

Semantically search for components by name, description, or member names using token-overlap scoring. Returns the top 3 matches with scores above zero.

libraryIdNoOptional library ID to target a specific loaded library instead of the default.
queryYesSearch query to match against component tag names, descriptions, and member names.
Behavior4/5

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

With no annotations, the description discloses key behavioral details: uses token-overlap scoring, returns top 3 matches with scores above zero. This is sufficient for a read-only search tool, though precise scoring mechanism could be expanded.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences efficiently convey purpose, method, and output constraints. No redundant information; every word contributes to clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Description specifies input and output (top 3 matches with scores >0) but omits details on the structure of matches (e.g., fields returned). Still, it provides essential context for an agent to invoke the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds context: query matches against tag names, descriptions, and member names. This enriches understanding beyond the schema's parameter descriptions, which are already clear.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it performs semantic search on components by multiple fields using token-overlap scoring, and distinguishes from sibling tools like find_components_by_token or list_components by specifying the search method and result criteria.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for fuzzy semantic matching but does not explicitly contrast with alternative search tools (e.g., exact match, listing). No when-not-to-use scenarios or prerequisites are mentioned.

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