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

Annotations already declare readOnlyHint=true, destructiveHint=false and idempotentHint=true, so safety is covered; the description adds useful context by stating it "opens nothing by itself" and that the return value is a step-by-step walkthrough of screens, buttons and fields. The note that Printify exposes a full REST API but has no official MCP server explains why the browser-tool path is necessary. It does not say what happens when no Printify browser session is active.

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 information (returns steps, does not act, follow up with cotlet_browser_* tools) is useful and reasonably tight. But the closing sentence about Printify's REST API and the "checked 17 Oct 2026" provenance note is tangential justification rather than invocation guidance, and the key clarification that this is an instructional tool is buried in clause two instead of leading.

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 zero parameters and no output schema, the definition is nearly sufficient, and it does describe the shape of the return value. However, for a tool that exists only to hand off to a browser session, it omits whether a Printify Cloud Browser must already be open and what the agent should do if the guide cannot be produced.

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 nothing for the description to disambiguate; baseline 4 applies. The description correctly implies the target account is fixed to "the user's own Printify account" rather than being passed in.

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 first sentence ("Cancel order in the user's own Printify account from ChatGPT, Claude or any AI agent") reads like the tool performs the cancellation, matching the misleading tool name. Only the second sentence reveals the real behavior — it returns step-by-step instructions and "opens nothing by itself." The corrective information exists but arrives late and the distinction from the sibling cotlet_app_guide is never made.

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: this tool returns the steps, then the actual work is done "with the cotlet_browser_* tools in the user's Printify Cloud Browser." That is a clear when-to-use and a named follow-up path. It stops short of stating when NOT to use it (e.g. versus cotlet_app_guide) or what preconditions the browser session must satisfy.

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