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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is fully covered. The description's only added behavioral note is that the payload includes live usage measured against caps, which is useful but thin given the annotation coverage.

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?

A single sentence with no wasted words, and the primary return (the capabilities record) is front-loaded ahead of the supporting payloads. It is efficient, though it stops short of the optimal front-loading that would name scope or role up front.

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?

With no output schema, the description carries the burden of describing returns, and it does list the three major payload groups. It stops short of describing the shape of the capabilities record or the usage-vs-caps structure, but it is adequate for a single-parameter read tool.

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?

There is a single optional parameter and schema description coverage is 100%, so the schema already explains the organization_id default and constraint. The description adds nothing about the parameter, which is the expected baseline here.

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?

States a specific verb+resource (return the workspace capabilities record) and enumerates the payload: use-case profiles and live usage vs caps. This is clear, but it does not distinguish itself from siblings such as request_capabilities or get_coverage, leaving ambiguity about which to select.

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 when-to-use guidance, no prerequisites, and no mention of alternatives. The presence of request_capabilities and get_coverage in the sibling list makes the absence of routing guidance a real gap, not a minor one.

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