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

No annotations are provided, so the description bears full behavioral burden. It does add genuinely useful substance about the return content — guarantees the component makes plus author responsibilities — which is more than the schema reveals. However it says nothing about output format, whether the notes are per-component static docs, or any other behavioral trait.

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?

A single short sentence that is front-loaded and wastes no words, so it is structurally clean. But the brevity here reads as under-specification rather than tight conciseness, since the sentence carries no usage, parameter, or format 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?

With no annotations, no output schema, and 0% parameter coverage, the description needs to carry most of the load for a documentation-retrieval tool. It explains the topic of the returned text but omits format, scope per component, and when it matters relative to the other get_* tools, leaving significant gaps.

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 description coverage is 0%, so the single required 'id' parameter is documented nowhere. The large enum self-documents the valid values, and the phrase 'the component' weakly ties id to a component identifier, but the description adds no explanation of what id means or how to choose it beyond the enum list itself.

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 is a noun fragment ('What the component guarantees and what the page author must do') that conveys the content of the notes but never states the action or resource explicitly — the verb 'get' lives only in the name/title. Combined with the title 'Accessibility notes' an agent can infer it returns accessibility obligations for a component, but it is not a clean verb+resource statement and does nothing to distinguish it from siblings like get_component or get_design_language.

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?

There is no statement of when to call this tool versus get_component, get_component_source, or get_design_language. The only signal is the implicit 'the component', which suggests it is scoped to a component id, but no trigger condition or alternative is named.

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