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

With no annotations, the description carries the full burden and does well: it discloses the read-only nature of the token, the scope of the data, and the security requirement to treat the link as a secret. It goes beyond a generic 'get URL' statement by explaining what the token cannot do.

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 two sentences with no filler. It front-loads the core purpose and then adds relevant security and non-mutation context, every sentence earning its place.

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 one-parameter tool with no output schema, the description covers the essential facts: what the URL contains, the scope of the data, the read-only nature, and the need to keep it secret. It could more explicitly connect guest_token to the feed token, but overall it is complete enough for correct selection and 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 0%, so the description must compensate. It refers to a 'feed token' that is read-only and secret, which maps naturally to the guest_token parameter, but it never explicitly says guest_token is that feed token or explains how it is used. Some meaning is added, but the mapping is left implicit.

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 identifies the artifact as a public URL containing JSON and RSS status for all the owner's endpoints, which is specific and useful. It lacks an explicit action verb like 'returns' or 'retrieves', but the tool name and noun phrase make the purpose clear.

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 description implies this is a read-only status-feed tool and warns it must not be used for creating, changing, or deleting anything. However, it does not explicitly say when to prefer this over the sibling status_feed_rotate or list_endpoints tools, so alternative selection is left to inference.

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