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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false. The description adds genuinely useful context beyond those: it states nothing is opened or changed by the call and that the return value is a screen/button/field walkthrough. The trailing REST-API/MCP note is peripheral rather than behavioral.

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 key facts (returns instructions, opens nothing, follow up with browser tools) are front-loaded and earn their place. But 'from ChatGPT, Claude or any AI agent' is filler, and the closing paragraph about ServiceTrade's REST API, OAuth2 and the absence of an official MCP server (checked 23 Oct 2026) does not help an agent decide or invoke and reads as vendor metadata.

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 full annotation coverage, the main burden is explaining what comes back and what to do next, and the description does both. A bit more on the shape of the step-by-step output (e.g., whether it is per-appointment or generic) would close the remaining gap.

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; baseline applies. The description correctly implies no input is required to obtain the instructions.

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 the concrete operation (releasing an appointment to technicians) and, importantly, clarifies that the tool only returns a step-by-step procedure rather than performing the action. That resolves the ambiguity created by the action-like tool name. It does not, however, distinguish itself from the other instruction-yielding siblings such as cotlet_app_guide.

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 establishes a clear workflow: call this to get the procedure, then execute it with the cotlet_browser_* tools. That is an explicit handoff to the alternative for the actual execution. It stops short of saying when NOT to use it or when cotlet_app_guide would be preferable.

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