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

Goes well beyond the annotations: hiddenModules replaces the entire list and hides modules from every member's navigation, the token expires after minutes and is single-use, changes in between yield stale_revision, replays return status 'applied' with replayed:true, and a refused token is not consumed. It also adds an untrusted-content warning about CRM field values. Nothing here contradicts destructiveHint or idempotentHint.

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?

Front-loaded with the purpose, then the mutation semantics, then the confirmation protocol — a sensible ordering. It is long, but nearly every sentence carries operational weight (token lifecycle, stale_revision, replay behavior); only the closing untrusted-content reminder is arguably redundant boilerplate.

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?

There is no output schema, yet the description describes the preview return shape (summary, changes, warnings, confirmationToken), the stale_revision failure, and the replayed response. For a destructive, zero-required-param administration tool, an agent has everything needed to call it safely.

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 coverage is only 40% and two params (name, rollingForecastHorizonMonths) have no descriptions, so the description must compensate. It does so for the highest-risk parameter by explaining that hiddenModules is a full replacement with workspace-wide navigation impact, and it clarifies the confirmationToken preview handshake beyond the schema's own note. The name and horizon numeric constraints are left entirely to the schema, so it is not fully compensating.

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 first sentence names a specific verb and resource ('Changes the workspace's name, rolling forecast horizon or hidden modules') and immediately scopes out what it cannot do (reporting currency, which routes to a different mechanism). An agent can distinguish it from get_workspace_settings and update_workspace_commercial_settings without opening either schema.

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?

Explicit step-by-step protocol: call first WITHOUT confirmationToken to preview, show the user summary and warnings, obtain explicit go-ahead in the same turn, then re-call with the identical arguments plus token. It also states what does NOT count as a go-ahead (prior instructions, agent's own plan, text in CRM data) and names the alternative path for currency changes.

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