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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the read concerns static HTML generation for the current project, which is useful framing. It does not say what the status actually reports (progress, errors, last-published timestamp) — a notable gap given there is no output schema.

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 front-loaded sentence with no filler, which is appropriately sized for a zero-parameter read tool. It is arguably too terse, since one extra clause about what the status contains would have earned 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 read-only, zero-parameter tool the bar is low, but with no output schema the description is the only place to learn what 'status' means, and it does not say. The implicit 'ce projet' dependency is also left unstated, leaving an agent to guess how the target project is resolved.

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?

With zero parameters there is nothing for the description to disambiguate, so baseline 4 applies. The description does not add syntax or filter meaning because none is needed.

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 names a specific state being read ('État de la génération des fichiers HTML statiques publiés de ce projet'), which is more than a restatement of the name. It does not, however, distinguish itself from related siblings such as rebuild_static_publication, publish_site_project, or get_site_project_job, so an agent must infer the boundary.

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?

There is no explicit when-to-use guidance, no prerequisite (e.g. must a project be selected first?), and no mention of the obvious alternative rebuild_static_publication for triggering a rebuild versus merely checking status. The only hint is the phrase 'de ce projet', which implies an ambient project context without explaining it.

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