update_file_snapshot

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

With no annotations provided, the description must disclose behavioral traits. It only states that it updates a snapshot's label/description but does not mention side effects, whether the snapshot must be unlocked, whether the old label is overwritten, or what the response looks like. This is a minimal disclosure beyond the name.

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, concise sentence that directly front-loads the action and target. There is no filler or redundancy, and it efficiently communicates the core purpose for a tool with only two parameters.

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 simple two-parameter update operation with complete schema coverage, the description provides the essential purpose. However, it lacks contextual details such as what a snapshot is, potential interactions with snapshot locking, or the effect of updating the label. This is adequate but not richly complete.

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 schema already provides 100% coverage with clear parameter descriptions: snapshotId is 'Snapshot ID to update' and label is 'New label/description for the snapshot'. The tool description merely echoes 'label/description' without adding any extra meaning beyond what the schema already states.

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 uses a specific verb 'update' and resource 'snapshot' with a specific target 'label/description'. This clearly distinguishes it from sibling snapshot operations like restore, lock, unlock, delete, and create, which focus on different actions.

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 no guidance on when to use this tool versus alternatives. It does not mention any conditions, prerequisites, or related tools such as restore or lock, leaving the agent to infer usage solely from the tool name and schema.

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