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

Annotations already declare readOnly/ idempotent/ non-destructive/ non-open-world, so the safety profile is covered. The description nonetheless adds two facts the annotations cannot convey: the tool performs no action and opens no page, and the official ResMan API is restricted to approved Integration Partners (so the browser route is the only path). It does not say what the instruction payload looks like in shape or length.

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 constraint (returns instructions, opens nothing) is front-loaded, which is good, but the opening clause 'from ChatGPT, Claude or any AI agent' is marketing filler and the partner-API aside is a long trailing sentence. Everything is packed into two dense sentences rather than separated into what-it-does / what-to-do-next.

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, annotated, read-only guide tool with no output schema, the definition supplies the essential pieces: it returns instructions, performs nothing, and hands off to the browser tools. A gap remains around prerequisites (e.g. whether the user must already be signed into ResMan Cloud Browser) before the handoff will work.

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 input schema takes zero parameters, which is the baseline-4 case; there are no arguments whose meaning needs elaboration. The description correctly implies no account selection is needed since it operates on the user's own ResMan account.

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?

Names the resource (vendors) and, crucially, corrects the naive reading of the title: the tool returns step-by-step instructions covering screens, buttons and fields rather than vendor records, and 'opens nothing by itself.' That is a specific and honest statement of function. It stops short of differentiating itself from the sibling resman_list_* tools, which appear to follow the same guide-then-browse pattern.

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?

Explicitly routes the agent to the follow-up path: perform the task afterwards with cotlet_browser_* tools in the user's ResMan Cloud Browser, and it excludes itself from executing anything. It gives no explicit when-not condition (e.g. what to do if the user has no browser session), so context is clear but not complete.

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