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

The annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, and the description's 'opens nothing by itself' is consistent with and reinforces that safety profile rather than contradicting it. It also discloses the return shape (screens, buttons, fields), which is useful. It adds little beyond that — no note on freshness of the instructions or limits on what UI flows are covered.

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?

The core clarification (returns instructions, executes nothing) is front-loaded and earns its place. However, 'from ChatGPT, Claude or any AI agent' is marketing filler and the trailing 'Help Scout's official API: Yes.' is ambiguous — it is unclear whether the Docs article update is even an API operation, which risks confusing the agent about what this tool returns.

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 zero-parameter, no-output-schema guidance tool, the description covers the return format and the follow-up step, which is adequate. It leaves open how the target article is identified given the absence of any input, and whether the guidance is generic or tailored — a meaningful gap for an agent deciding whether to call it.

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 tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description does not need to compensate for any schema gap.

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 names the specific resource (Docs article in the user's own Help Scout account) and, crucially, clarifies that the tool does not perform the update itself — it returns step-by-step instructions. That resolves the mismatch an agent would otherwise infer from the 'update' verb. It stops short of distinguishing this guidance tool from sibling guidance tools such as cotlet_app_guide.

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 sequencing hint — get instructions here, then execute with cotlet_browser_* tools in the user's Help Scout Cloud Browser — which is real workflow guidance. It does not say when to prefer this over other guidance tools or when it is unnecessary (e.g., if the agent already knows the UI steps).

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