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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=false, so the safety profile is covered. The description adds one genuinely new behavioral fact, the invariant that at least one slide must remain, but says nothing about whether the deletion is reversible or how indices shift afterward.

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 sentence with the action front-loaded and the constraint in a compact parenthetical; nothing is redundant. It is economical to the point of leaving out recoverability and index-shift details, but that is a completeness issue rather than verbosity.

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 two-parameter deletion tool with full schema coverage, strong annotations and no output schema, the description supplies the purpose and the key invariant. Only secondary details (permanence of deletion, index renumbering) are absent, which is acceptable at this complexity.

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 both parameters (id, index) are already documented in the schema, including the 0-based index convention. The description only restates that index is a rank, adding no syntax or format 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?

The description states a specific verb and resource ('Supprimer la diapositive') plus the addressing scheme ('de rang index'), so an agent knows exactly what object is affected. It does not distinguish itself from siblings such as delete_presentation or move_slide/update_slide, but the operation itself is unambiguous.

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 or named alternative (e.g., move_slide or delete_presentation). The parenthetical 'une présentation garde au moins une diapositive' does convey the precondition that the last remaining slide cannot be deleted, which is useful implied guidance.

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