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

The description's "opens nothing by itself" and "returns how to do it step by step" are consistent with readOnlyHint=true and destructiveHint=false, adding useful confirmation of the no-side-effect contract. However, it does not mention prerequisites such as the user being logged into the Cloud Browser session, and it adds limited behavior beyond what the annotations already imply.

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?

Front-loads the outcome (step-by-step guidance, no side effects) and then the execution path in three tight sentences. The final sentence about the missing public API is slightly awkward in phrasing but earns its place by justifying the browser-tool route.

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 tool with no output schema, the definition covers what it returns (screens, buttons, fields) and what to do next, which is the information an agent needs. The main gap is operational context about the Cloud Browser session state required to complete the task.

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 the schema needs no elaboration and there is no parameter meaning for the description to supply. Baseline applies.

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 ("Configure client habit") and, critically, clarifies that it only returns step-by-step instructions rather than performing the action. It does not explicitly differentiate itself from the close sibling manage_self_coaching_habits, but the agent can still tell it produces guidance, not a mutation.

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 a clear procedural path: call this to get the screens/buttons/fields, then execute with cotlet_browser_* tools in the Cloud Browser. No exclusions are stated, so there is no guidance on when NOT to use it versus self-coaching habit siblings.

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