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

Annotations already declare readOnlyHint=true, so the safety profile is covered and the bar is lower. The description adds real value beyond that by disclosing the exact fields returned (id, name, description, status, order, showUptime, grouped, archived) and the underlying endpoint GET /v2/{page_id}/components, which matters because no output schema exists.

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?

Three short clauses with the purpose and returned fields front-loaded before the endpoint reference. No filler text, though the raw field enumeration is dense and the endpoint citation is arguably redundant with the tool name.

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 read-only list tool with no output schema, the description compensates by naming the returned fields, and pagination details are fully covered by the 100%-covered input schema. The main remaining gap is how this differs from instatus_get_component, but nothing needed to invoke the tool correctly is missing.

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 page, page_id, and per_page are all documented in the schema with defaults and bounds; the baseline is 3. The description only implies the page scoping ('a status page's components') and adds nothing about pagination syntax or formats beyond what the schema already provides.

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?

States a specific verb (List) and resource (a status page's components) and enumerates the returned fields, so the agent knows exactly what comes back. It does not explicitly distinguish itself from the sibling instatus_get_component, so it falls short of full sibling differentiation.

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 line 'The component ids are what you set impact on' implies downstream usage (incident impact), which gives some context for why an agent would call this. However, there is no explicit when-to-use guidance, no statement of when to prefer instatus_get_component, and no prerequisites beyond the schema-level page_id.

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