e_set_workspace

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that the tool 'Creates cache folder automatically' and 'optionally re-indexes', which are important behavioral traits beyond just changing a path. However, it doesn't address potential side effects like what happens to existing workspace state, whether this requires specific permissions, or if there are any rate limits or constraints on workspace switching.

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 efficiently structured in two sentences that each earn their place: the first states the core purpose and usage context, the second adds important behavioral details about cache creation and re-indexing. There's no wasted verbiage and information is front-loaded appropriately.

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 mutation tool with no annotations and no output schema, the description provides adequate coverage of the core functionality but lacks completeness. It doesn't describe what the tool returns (success/failure indicators, error conditions), doesn't explain what 're-indexing' entails in practical terms, and doesn't address potential failure modes or constraints on the workspace path parameter beyond it being 'absolute'.

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 100% schema description coverage, the schema already documents all three parameters thoroughly. The description adds minimal value beyond the schema - it mentions 'optionally re-indexes' which relates to the 'reindex' parameter, but doesn't provide additional semantic context about parameter interactions or usage patterns beyond what's in the schema descriptions.

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 specific action ('Change the project workspace path at runtime') and resource ('workspace'), distinguishing it from siblings like 'clear_cache' or 'get_status'. It explicitly mentions creating cache folders and re-indexing, which differentiates it from simple path-setting 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?

The description provides clear context for when to use this tool ('when you detect the current workspace is incorrect or you need to switch to a different project directory'), but doesn't explicitly state when NOT to use it or name specific alternatives among the sibling tools (e.g., when to use 'clear_cache' separately vs. using the clearCache parameter here).

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