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

Beyond the readOnlyHint/openWorldHint annotations, the description adds real behavioral context: it opens nothing by itself, it returns screen/button/field-level steps, and the actual mutation must happen through the cotlet_browser_* tools. This is consistent with readOnlyHint=true and destructiveHint=false. Only the handoff failure modes (e.g., no browser session) are left unstated.

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 core instruction is front-loaded and clear, but filler like 'from ChatGPT, Claude or any AI agent' and the trailing trivia about Skedda's official API/beta MCP status consume space without helping an agent decide or act. The middle sentence carries almost all the operative content.

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, side-effect-free guidance tool with no output schema, the description covers what it returns and what the caller must do next. It could be slightly more complete about the shape of the returned steps (e.g., preconditions like being logged in), but nothing essential for correct invocation is missing.

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 beyond what the empty schema already conveys. Baseline of 4 applies; no parameter-level detail is needed.

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 verb and resource (approve a booking request in Skedda) and immediately clarifies the tool's actual output is step-by-step guidance rather than the approval itself. It does not explicitly contrast with siblings like skedda_cancel_booking or skedda_create_booking, but the operation is unambiguous from the name-plus-description pairing.

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 a clear usage path: call this first to get instructions, then perform the approval with the cotlet_browser_* tools in the user's Skedda Cloud Browser. It also implicitly rules out an API route by noting Skedda's API is read-only, but it does not state explicit conditions for when not to use this tool (e.g., already knowing the steps).

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