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

With no annotations, the description carries the disclosure burden well: it explicitly states this never returns a signing secret and describes the intended server-side HS256 token flow. That is real behavioral context an agent would not otherwise know. It stops short of describing the returned document's exact format, so not 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, purpose front-loaded, followed by the key security caveat and the intended flow. Zero wasted text.

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?

For a documentation-returning tool with no annotations or output schema, the description explains what the returned contract is for and what it does not contain (a secret). It could better describe the shape of the returned guide, but an agent has enough to call it correctly.

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?

The single parameter bot_id has 0% schema description coverage, so the description should compensate but does not mention it at all. The parameter is self-evident enough to avoid a lower score, but it 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 and resource: it returns the secure integration contract for passing a logged-in customer to the widget. An agent can see it is a documentation/guide getter rather than a mutation, distinguishing it from the config siblings. It does not name a specific sibling alternative, keeping it at 4.

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?

Usage is implied by the described flow (server mints a short-lived HS256 token, then passes it to window.Chatty.identify()), which gives context for when an integrator would call this. However, there is no explicit when/when-not guidance or any named alternative among the many configure_* siblings.

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