set_workspace

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

With no annotations, the description carries the full behavioral burden. It does add useful context: the operation sets session state and returns a confirmation string. However, it does not disclose whether the workspace must already exist, how this affects subsequent tool calls, or whether the change is persistent across sessions.

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 concise and front-loaded with the key purpose, followed by compact Args and Returns sections. The ctx line is slightly extraneous since it is absent from the schema, but overall the structure is organized and free of unnecessary prose.

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 simplicity, the description covers the core purpose, parameter meaning, and return value. Gaps remain: there is no usage guidance, no mention of validation behavior, and no indication of what 'current workspace' affects. For a simple setter with no annotations and no output schema, this is adequate but not 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 only provides the property name 'workspace' with no description, so the description's clarification that it accepts 'Name or ID' adds meaningful semantics. The extra 'ctx' argument is not present in the input schema and could be confusing, but the primary parameter is adequately explained.

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 a specific verb and resource: 'Set the current workspace for the session.' This distinguishes it from sibling tools like set_warehouse and set_lakehouse because the target resource is explicitly named. It does not explicitly differentiate from list_workspaces or create_workspace, but the action is unambiguous.

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?

There is no guidance about when to use this tool versus alternatives such as list_workspaces, create_workspace, or other set_* tools. The phrase 'for the session' implies a stateful selection, but no conditions, prerequisites, or exclusions are given.

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