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

The readOnlyHint already tells the agent this is a safe read. The description adds meaningful context beyond that by listing the returned state fields (name, description, status, order, showUptime, grouped, archived) and the underlying API endpoint, which helps the agent understand the response shape without an output schema.

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 one tight sentence followed by the API route, with the key fact — retrieving a single component by id — front-loaded. Every part earns its place and there is no filler.

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 simple read-only lookup with full schema coverage and annotations, the definition is complete. It names the resource, the identifying parameters, the returned fields, and the endpoint, leaving no meaningful gap for correct invocation.

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 100%, so the schema already fully documents page_id and component_id. The description echoes the id-based access and embeds the parameters in the GET path, but adds no significant semantic detail beyond what the schema provides, matching the baseline for high coverage.

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 states a specific verb (Get) and resource (a single component), and explicitly distinguishes it from list-based siblings by emphasizing 'single component by id'. It also previews the full returned state, so an agent knows exactly what the tool does.

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?

It implies usage when you have a component ID, but gives no explicit when-to-use guidance, no conditions for choosing it over instatus_list_components, and no exclusions. The context is clear enough to infer the basic use case, but alternatives are not addressed.

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