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

With no annotations, the description carries the full burden and does reasonably well: it declares the auth requirement (platform staff, account session) and explicitly scopes out what is NOT returned ('No transcripts, recordings or contact details'), which is genuinely useful negative disclosure. It does not address error behavior (e.g. unknown/inaccessible workspaceId), keeping it below a 5.

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?

Two tight sentences, front-loaded with the access constraint and the 'one workspace' scope before the payload enumeration. The field list is dense but every item earns its place given there is no output schema.

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 usefully enumerates the return contents and the auth precondition, and states the exclusions. Missing only edge-case behavior (not-found / permission-denied responses) and any mention of the identifier argument, so it is nearly complete for a single-entity read.

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 is expected to compensate, and it does not mention workspaceId at all. The parameter is largely self-explanatory from its name and the schema's uuid format/pattern constraint, so the gap is mild, but the description adds no meaning beyond the schema.

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 ('One workspace') and enumerates the data returned (owner, members, lines with health, agents, usage, credits, etc.), which clearly separates it from platform_workspaces_list. It stops short of naming the sibling, but the 'one vs many' framing makes the distinction inferable.

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?

'Platform staff only (account session)' gives a real access precondition, which is more than most definitions offer. However, there is no explicit when-to-use/when-not guidance versus platform_workspaces_list or platform_accounts_get, leaving the agent to infer that this is the single-workspace detail view.

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