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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false and idempotentHint=true, and 'opens nothing by itself' largely restates that. The genuine additive disclosure is that no public SimplePractice API exists, explaining why a browser-driven guide is needed. Auth/session requirements for the Cloud Browser, which matter here, go unmentioned.

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 purpose and the handoff are front-loaded, but the phrasing is padded: 'from ChatGPT, Claude or any AI agent' is marketing filler, and the second sentence packs guide-return, no-side-effects and next-step routing into one long chain. The API note with a dated check is useful but tacked on awkwardly.

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 strong annotation coverage, the description supplies what an agent needs: what it returns (a procedural guide), that it has no side effects, and which tool family executes it. Remaining gaps are session/auth prerequisites and how the guide's freshness is guaranteed.

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; the schema is fully closed and unambiguous. The description correctly implies no input is required. Baseline 4 applies for a parameterless tool.

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 specific resource (claims) and scope (the user's own SimplePractice account), and crucially discloses that the tool does not itself list claims but returns a step-by-step guide of screens, buttons and fields. This distinguishes it from the cotlet_browser_* execution tools. The only weakness is that the name/title ('List claims') diverges from the actual behavior, which the description has to correct mid-sentence.

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 explicitly states the usage sequence: call this to get the procedure, then carry it out with cotlet_browser_* tools in the user's SimplePractice Cloud Browser. That is concrete routing to alternatives. It stops short of stating preconditions (e.g. that a Cloud Browser session must already be open or authenticated) or when-not-to-use cases.

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