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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description still adds real value by stating it 'opens nothing by itself' and that output is step-by-step screens, buttons, and fields, plus a note on official API availability. It stops short of describing the return shape or length of that guidance.

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?

Sentences are run-on and poorly ordered: audience marketing ('from ChatGPT, Claude or any AI agent') is front-loaded while the actual behavior arrives mid-sentence, and the trailing fragment 'Anaplan's official API: Yes.' carries little meaning. The 'opens nothing by itself; then do it with...' clause is jammed into one sentence, making the flow hard to parse.

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 parameters and no output schema, the description must explain what comes back, and it only gestures at 'step by step (screens, buttons, fields)' without describing format or scope. It does correctly point to the cotlet_browser_* tools needed to act on the result, but leaves the agent unsure whether any model data is returned at all.

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 meaning to convey and the baseline is 4. Nothing in the description misdescribes inputs, and no arguments are implied that the empty schema would reject.

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 name and title promise a model listing, but the description says it 'Returns how to do it in Anaplan step by step (screens, buttons, fields) and opens nothing by itself', i.e. it returns instructions rather than models. An agent cannot tell from the text whether it gets data or a procedure, and the phrasing conflicts with the name. The only unambiguous part is that it does not itself perform the action.

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?

There is explicit sequencing guidance: get the steps here, then execute them with the cotlet_browser_* tools in the Anaplan Cloud Browser. However, it gives no conditions for choosing this over sibling Anaplan tools such as anaplan_list_actions or anaplan_get_model_history, and no when-not-to-use guidance.

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