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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false; the description adds the non-obvious behavioral fact that the tool performs no action and returns procedural instructions instead. It also explains why browser automation is needed (no official MCP server, only a REST API with OAuth2), which is useful context an agent cannot get from annotations. It does not describe the shape of the returned 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?

The operative content is front-loaded and clear, but the opening phrase "from ChatGPT, Claude or any AI agent" is marketing filler, and the trailing API/OAuth2 sentence with a dated check ("checked 23 Oct 2026") is tangential to invoking the tool. Roughly a third of the text does not help an agent call it correctly.

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, non-destructive guidance tool with annotations covering safety and no output schema, the description supplies what matters: what it returns (step-by-step screens/buttons/fields), what it does not do (opens nothing), and what to do next. Only the return structure and any scope limits on which jobs are covered remain unstated.

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 schema semantics for the description to supplement; the baseline for a parameterless tool applies. The description correctly implies the call needs no input beyond the user's own account context.

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 ("List jobs in the user's own ServiceTrade account") and immediately corrects the likely misreading by saying it "Returns how to do it in ServiceTrade step by step (screens, buttons, fields)" rather than job data. That is a clear, agent-usable statement of purpose, though it never contrasts itself with sibling servicetrade_* tools that likely work the same way.

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 an explicit workflow: call this to get the procedure, then "do it with the cotlet_browser_* tools in the user's ServiceTrade Cloud Browser," and states that it "opens nothing by itself." It lacks any when-not guidance or comparison against sibling servicetrade_list_deficiencies or the cotlet_app_guide tool, so the agent must infer alternatives.

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