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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds no behavioral context such as return format, pagination, or rate limits. With annotations present, the bar is lower, but the description still contributes nothing beyond the endpoint path.

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 extremely concise – a single string with the HTTP method and path. It is not verbose, but it is also minimal to the point of being under-specified. For a simple list endpoint, this brevity is acceptable, though a short sentence describing the action would be more structured.

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 that an output schema exists and annotations cover safety, the description still lacks essential context such as what the response contains, whether pagination is involved, or how this relates to sibling workspace tools (none exist). It is barely complete enough for an agent to invoke correctly, relying almost entirely on the tool name and annotations.

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 tool has zero parameters and the schema is empty with 100% coverage. Since there are no parameters to document, the description does not need to add parameter semantics. Baseline for 0 params is 4, and the description does not detract from this.

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 'GET /v1/workspaces' conveys the HTTP method and resource but does not explicitly state it lists workspaces. It is clearer than a tautology but lacks a descriptive verb beyond the implied GET. It does not differentiate from sibling tools beyond the resource name, though no other tool targets workspaces.

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 on when to use this tool vs. alternatives. No mention of filtering, pagination, or context that would help an agent decide between this and sibling list tools like get_channels or get_posts. The description provides zero usage direction.

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