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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds real behavioral value beyond that: it discloses the fallback behavior when publishId is omitted and enumerates the possible states the publish can be in (live, setting up, or failed). It does not cover permissions or latency, but the added context is substantive.

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?

A single tightly packed sentence that front-loads the outcome and then lists the returned fields. There is no filler, though the colon-heavy structure is a touch dense for an agent to parse quickly.

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?

There is no output schema, so the description carries the return-value burden and does so by naming the fields an agent gets back. Combined with read-only annotations and the fallback rule, an agent has enough to call and interpret this tool correctly; only projectId semantics are thin.

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 50%. The schema documents publishId as coming from uichemy_publish_site, and the description reinforces its optional/conditional role. However, projectId is left completely undocumented in both the schema and the description, so the description does not fully compensate for the coverage gap. Baseline 3 fits.

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 publish / the project's hosted site) and enumerates the status fields returned (address, live/setting-up/failed, last publish time), which lets an agent recognize this as a status-query tool. It does not name sibling tools such as uichemy_publish_site or uichemy_list_sites to sharpen the boundary, and the phrasing 'Where a publish is up to' is slightly indirect.

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 gives one useful conditional: if no publishId is supplied, the tool reports the project's hosted site instead of a specific publish. That implies usage but there is no explicit when-to-use vs alternatives (e.g., versus uichemy_publish_site to start a publish, or uichemy_list_sites), and no exclusions or prerequisites.

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