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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered; the description adds real value by disclosing the return format (Markdown, title/description/text, navigation stripped) and the public-pages-only limitation. It does not say what happens on a non-existent or private URL, which keeps it from a 5.

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?

Three short sentences: output first, then accepted input, then scope limitation. No redundancy and nothing that fails to earn 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 one-parameter read-only fetch tool with full schema coverage and no output schema, the description supplies exactly what is missing: the response shape (Markdown without navigation) and the readability boundary. Nothing an agent needs to call it correctly is absent.

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 description coverage is 100% and already documents the accepted forms (https URL or path starting with /). The description restates the same duality with an example path (/audit-ia/) but adds no constraint detail beyond the schema, 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?

States a specific verb ("Renvoie le contenu") and resource (a page of data-slconsulting.com) plus the output format (Markdown, titre/description/texte, sans navigation). It does not explicitly contrast with siblings get_offers or search_site, so the agent must infer that this is the page-reader versus the search 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?

"Seules les pages publiques du site sont lisibles" gives an implicit boundary and the accepted input forms suggest when it applies, but no alternative is named (e.g. use search_site to find a page first, get_offers for offers). Usage is implied rather than stated.

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