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

Adds substantial behavioral context beyond the annotations: per-guest conversation caps, link expiry, the possible `needs_confirmation` return envelope, and the required response ('say who the link is for and wait'). The annotations confirm a non-read-only, open-world, non-destructive operation, and the description enriches this with concrete operational constraints.

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-loads the core purpose in the first clause, then layers precondition, behavioral traits, and the confirmation protocol. Every sentence carries distinct, load-bearing information with no filler.

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 still covers the meaningful return signals (link, expiry, needs_confirmation) and the full lifecycle (list/revoke). An agent has everything needed to invoke it correctly and handle the response.

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 100%, so the baseline is 3, but the description adds real meaning to `label` ('say who the link is for') and `approvalId` (implicitly tied to the needs_confirmation flow) that the schema alone only lightly conveys.

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 and resource ('Creates a no-account guest link' to the flow's latest PUBLISHED revision) and even names the surface (/s/<token> page). It is immediately distinguishable from siblings like workbench_flows_publish and workbench_flows_shares_list, which it explicitly references.

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 explicit usage context ('the fastest way to put a working flow in a stakeholder's hands'), a precondition (flow must have a published version, checked via workbench_flows_revisions_list, published via workbench_flows_publish), and names the alternatives for managing/removing links (shares_list, shares_revoke).

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