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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds valuable operational details not in annotations: 5-second timeout, 512 KB cap, only public addresses, no API key needed, and that the answer carries the related POST request's body. It doesn't discuss retry behavior or rate limits, but this is solid added context.

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?

Front-loads the core read operation and its return fields, then layers on usage guidance and operational constraints. It is denser than necessary in places and could benefit from splitting the POST-related context, but every sentence adds 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 a single-parameter, read-only tool with full annotation coverage and no output schema, the description is broadly complete: it covers what is read, constraints (public only, timeout, size cap), auth (no key), and the related write flow. Minor gaps remain around return format specifics and error behavior, but nothing critical is missing 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 coverage is 100% and the single url parameter is documented in the schema. The description adds useful flexibility hints (pass any address on the page, not just the JSON URL) which is beyond the schema, but does not detail format constraints or edge cases beyond that. Baseline 3 is appropriate when the schema does the heavy lifting.

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 precise verb and resource: reads a public Atlassian Statuspage page, enumerating exactly what is returned (name, overall status, components, unresolved incidents) and the data source (/api/v2/summary.json). This is distinguishable from every sibling tool.

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?

Gives explicit usage context (use it before POST /api/v1/statuspage) and describes the related write flow. It also states the exclusion (private pages cannot be read). However, it does not direct to a specific sibling alternative for cases where this tool is unsuitable, only noting private pages are out of scope.

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