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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds a genuinely useful behavioral note — no workspace selection needed and no quota reserved — but says nothing about response shape, ordering, or account-mode interactions that the schema hints at.

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 short sentences, front-loaded with the identifying phrase and followed by the constraint that matters. No filler, though the leading 'Unified Dutify list_workspaces:' is partly redundant with the tool name.

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 annotations covering safety and no output schema required, the definition is nearly adequate. Still, for a discovery tool it never states what the caller gets back (workspace names/identifiers) or how the account/workspace params relate on this specific call, leaving a small but real gap.

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%, so both parameters are fully documented in the schema itself. The description adds no parameter-level meaning beyond that, which is the expected baseline when the schema does the work.

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 states the resource ('workspace discovery') and qualifies it as 'fresh credential/workspace', making clear it enumerates workspaces visible to the current credentials. It does not, however, differentiate against close siblings like find_my_workspace or list_accounts, leaving the agent to infer the distinction.

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?

It gives a usable precondition — 'Does not require a selected workspace or reserve quota' — which implies this is the call to make before workspace context exists. But it names no alternative and never says when to prefer find_my_workspace or how it relates to list_accounts, so guidance is only implied.

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