sb_update_snapshot

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

No annotations are provided, so the description must fully disclose behavioral traits. However, it only states 'Update a snapshot's description or labels' without mentioning required identifiers, preconditions (e.g., snapshot must exist), side effects, or idempotency. This is inadequate for a mutation tool.

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 a single, front-loaded sentence with no unnecessary words. It is concise, though a slight expansion to include required identifiers would improve clarity without much 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 4-parameter mutation tool with no annotations, the description is too sparse. It omits important details like which parameters are required and what happens when optional parameters are omitted. The presence of an output schema is not leveraged to explain return values. More context is needed for safe and correct usage.

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?

The description mentions the two modifiable parameters (description and labels), adding some context beyond the schema. However, it does not explain the required identifiers (storage_box_id, snapshot_id) or the format of the labels object. Given 0% schema description coverage, the description partially compensates but leaves gaps.

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 action ('Update'), the resource ('snapshot'), and the scope ('description or labels'). It distinguishes this tool from siblings like sb_create_snapshot, sb_get_snapshot, sb_delete_snapshot, and sb_rollback_storage_box_to_snapshot, which cover other lifecycle operations.

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?

No guidance on when to use this tool versus alternatives. For example, there is no mention that sb_get_snapshot should be used for viewing a snapshot's current state, or that sb_rollback_storage_box_to_snapshot is for reverting to a previous snapshot.

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