Update snippet folder metadata

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

Annotations already show this is a write operation (readOnlyHint=false), non-destructive, and idempotent. The description adds that color/icon are the affected fields, but says nothing about how omitted properties behave or whether name is an identifier vs new value; no contradiction with annotations.

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 compact, but the first sentence repeats the tool title verbatim and the second repeats 'of a snippet folder,' introducing redundancy. It is not excessively long, but not every sentence earns its place.

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 three-string-parameter update tool, annotations cover safety and idempotency. However, the absence of an output schema and no explanation of the required `name`/update semantics leaves an agent guessing about how to construct a correct call.

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 0%, so the description must compensate. It only labels color and icon as metadata; it does not explain the required `name` parameter's role or acceptable formats/values for color/icon, leaving a critical ambiguity.

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 names a specific verb ('Update'), resource ('snippet folder'), and concrete fields ('color, icon'), so an agent can tell this is a mutation of folder metadata rather than folder creation. However, it does not explicitly differentiate from sibling rename_snippet_folder, and it omits the required name field from its scope.

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 when-to-use or alternatives are mentioned. The sibling list contains rename_snippet_folder, create_new_snippet_folder, and hosts_update_folder_metadata, but the description gives no condition for selecting this tool over them.

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