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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, and the description still adds substantive context: the feed token's authority is limited to reading status and cannot create, change or delete anything. It also discloses the real risk — anyone holding the link sees the dashboard, so it must be treated as a secret — which is exactly the kind of operational consequence annotations cannot express.

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?

Two tight sentences with no waste: the resource and its formats come first, then the security constraint. Every clause carries information an agent needs.

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 one-parameter read tool with no output schema, the description covers what is returned (a URL, in JSON and RSS), the scope of the token, and the confidentiality requirement. It stops short of stating whether the URL expires or what status_feed_rotate does to an existing link, which matters for an agent deciding whether to cache or re-request it.

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 guest_token parameter is fully documented in the schema, including the X-Guest-Token header. The description references owner scoping but adds no syntax, format or fallback detail beyond what the schema already provides, so the baseline 3 applies.

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 resource (a public status feed URL) and its two formats (JSON and RSS), scoped to all of the owner's endpoints. It is clear enough to distinguish from listing tools, but it never names its closest sibling status_feed_rotate, so the create-vs-rotate distinction is left to inference.

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?

Use is only implied: an agent can infer this is for obtaining a shareable read-only status link. There is no explicit 'use this when...' statement, no mention of when to prefer it over status_feed_rotate, and no note on whether the URL is stable or must be re-fetched.

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