sb_update_snapshot_plan

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

The description discloses that unset fields default to wildcard and that setting max_snapshots=0 disables retention. This adds valuable behavioral context beyond the input schema, especially given the lack of annotations. It could mention side effects or required permissions.

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 two sentences plus a short lead, all front-loaded with the purpose. Every sentence adds value without 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 6 parameters, no annotations, and an output schema, the description covers purpose, default behavior, and a key special case. It could mention that storage_box_id must exist, but is otherwise adequate for typical use.

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 0% schema coverage, the description adds meaning by explaining default behavior and the special case for max_snapshots. However, it does not detail the allowed values or format for minute, hour, etc., beyond saying they default to wildcard.

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 'Configure the automatic snapshot schedule for a Storage Box,' which is a specific verb+resource combination. It distinguishes from sibling tools such as sb_get_snapshot_plan (view schedule) and sb_create_snapshot (one-time snapshot).

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 usage guidance on default behavior and disabling retention, but does not explicitly state when to use this tool versus alternatives. However, the context of sibling tools makes it clear this is for modification.

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