Replace the enabled set of Scaleway Audit Trail custom alert rules

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

The description discloses that the operation is atomic and full-replace (disables rules not listed), requires confirm=true, and has specific permission needs beyond read-only. The annotations (destructiveHint=true, idempotentHint=true) are consistent and the description adds valuable context about the 501 error and non-retry advice.

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 slightly long but every sentence is useful and well-structured. It front-loads the core purpose and then provides context, alternative, requirements, and a caveat. No redundancy.

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?

Given the tool's complexity (destructive full-replace, permission requirements, API caveat, alternative), the description covers all needed aspects: purpose, when to use, prerequisites, error handling, and fallback. The absence of an output schema is acceptable since the tool is a mutation and the description mentions the error behavior.

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 100% and the schema descriptions are already clear. The description reiterates the full-replace semantics for enabled_custom_alert_rule_ids and the confirm requirement, but does not add significant new meaning beyond what the schema provides.

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 clearly states the verb (replace) and resource (the complete set of enabled custom alert rules), and explicitly distinguishes from the sibling tool scaleway_audit_set_custom_alert_rules_enabled by noting the difference between full-replace and additive semantics.

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 provides explicit guidance: prefer the additive sibling unless full-replace is needed, requires confirm=true, and details permission requirements with a specific fallback (scaleway_iam_set_policy_rules). It also includes a caveat about a 501 error and advises not to retry, directing to an alternative.

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