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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with the important disclosure that the tool 'opens nothing by itself' — critical for an agent that might otherwise assume the task was created. It also describes the shape of the return value (screens, buttons, fields) and the API-key prerequisite for the alternative route. Minor filler ('checked 20 Oct 2026') adds little.

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 essential facts — returns steps, creates nothing, then use browser tools — are buried behind a marketing-flavored opening clause and a parenthetical date stamp. The API-key path and the 'no official MCP server' aside are useful context but could be tightened considerably.

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 guide tool with no output schema, the description covers what it returns (step-by-step screens/buttons/fields), what it does not do (opens nothing), and what to do next (cotlet_browser_* tools). An agent has enough to call it and act on the result, though the exact return format remains implicit.

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?

There are zero parameters, so per the baseline this is a 4. The description adds no parameter information, but none is needed for an empty object schema.

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 eventually makes clear this is a guidance tool: it 'Returns how to do it in JazzHR step by step (screens, buttons, fields) and opens nothing by itself.' That distinguishes it from the cotlet_browser_* siblings that actually perform the action. However, the opening sentence 'Create task in the user's own JazzHR account from ChatGPT, Claude or any AI agent' reads like the tool performs the creation, creating internal tension with the read-only behavior stated two clauses later.

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 concrete workflow: call this first to get the steps, then 'do it with the cotlet_browser_* tools in the user's JazzHR Cloud Browser.' It also notes the official REST API exists but there is no official MCP server, explaining why the browser route is used. No explicit when-not-to-use case is given, but the sequencing guidance is clear.

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