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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so safety is covered; the description still adds meaningful context by stating that nothing is opened or changed and that the returned payload is procedural instructions. The note that DistroKid has no public API, developer docs, or official MCP server explains why the browser tools are the follow-up path. It stops short of saying what the response looks like structurally or whether a Cloud Browser session must already exist.

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?

Three sentences, front-loaded with the action and immediately qualified by what the tool actually returns and how to complete the task. The closing API-availability sentence earns its place as justification for the browser-tool workflow, though the embedded verification date is slightly noisy.

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, no output schema, and annotations covering the safety profile, the description covers the essentials an agent needs: what comes back, that nothing is mutated, and which tools finish the job. Only preconditions (an existing DistroKid login/Cloud Browser session) are left 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 nothing for the description to disambiguate and the baseline of 4 applies. One minor gap: it never says how the target release is identified when no release identifier can be passed, which an agent might briefly wonder about.

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 a concrete resource (a release in the user's own DistroKid account) and clarifies the actual behavior: it returns step-by-step instructions with screens, buttons and fields rather than performing edits. That clarification is necessary because the leading phrase 'Edit release ... from ChatGPT' implies an action the tool does not take, so the reader must reconcile the two sentences before selecting it.

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 an explicit workflow: call this first to get the steps, then carry them out with the cotlet_browser_* tools in the user's DistroKid Cloud Browser, and it explicitly excludes the tool itself from acting ('opens nothing by itself'). It does not distinguish against the other distrokid_* siblings (e.g. get_release_status, set_splits), which would be needed for a full 5.

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