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

Annotations only supply openWorldHint and idempotentHint, leaving safety and permission behavior undocumented, and the description usefully fills part of that gap: account-wide key required, plan gating, and the Default-workspace archive exclusion. It still does not say what happens to contained resources (designs, stores, products) when a workspace is archived, nor whether archiving is reversible, so the mutation's blast radius is only partly disclosed.

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?

Three short, front-loaded sentences that each carry information: action, restriction, prerequisite. The trailing '[#e8ebf4]' is stray markup noise that slightly detracts but does not obscure meaning.

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 return-value burden, but for a rename/archive mutation the key operator facts (plan requirement, key scope, default-workspace exclusion) are present alongside annotations that already signal idempotency. What is missing is the post-archive state of dependent resources.

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 100% and each of the three parameters (name with max length, archived boolean, workspace_uuid with its source tool) is already documented in the schema. The description adds no parameter-level detail beyond what the schema provides, so the baseline 3 applies.

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 specific verbs and resource: rename a workspace, or archive/unarchive it. This cleanly separates it from create_workspace, delete_workspace, and list_my_workspaces. It does not name a sibling directly, but the action set is unambiguous.

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?

Gives prerequisites (agency/Enterprise plan, account-wide key) and one restriction (Default workspace cannot be archived), which is genuinely useful context for deciding whether the call will succeed. However, it never states when to prefer this over alternatives such as delete_workspace or check_workspace_deletion, so usage remains implied.

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