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

The annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false; the description usefully confirms this by stating it 'opens nothing by itself,' which is non-obvious given the tool name. However, it adds little else operationally — no statement about the return shape (a steps list?), prerequisites (an active JazzHR browser session), or failure behavior when no session exists.

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 behavior and the hand-off to browser tools are front-loaded and earn their place. The trailing sentence about JazzHR's REST API and lack of an official MCP server is dated trivia that only marginally supports the agent's decision-making, padding an otherwise tight definition.

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 input schema, no output schema and low complexity, the description covers the essentials but omits two things an agent needs: what the response actually looks like (structured steps vs. prose) and the prerequisite of an open JazzHR Cloud Browser session. Adequate but with clear gaps.

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 and additionalProperties is false, so the baseline is 4 and there is nothing for the description to disambiguate. One could argue it should explain why no job fields are accepted, but the description implies the fields are surfaced in the returned steps instead.

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 makes the actual behavior explicit: it returns step-by-step instructions (screens, buttons, fields) for creating a job rather than creating one. That resolves the ambiguity created by the name/title 'create job' and distinguishes it from the cotlet_browser_* siblings that do the real work. It loses a point only because the opening sentence 'Create job in the user's own JazzHR account' initially reads as a write action before being corrected mid-paragraph.

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 two-step workflow: call this tool first for the procedural guide, then execute with cotlet_browser_* inside the user's JazzHR Cloud Browser. There are no explicit exclusions (e.g., when to skip the guide and drive the browser directly, or what to do if a session is not open), so it stops short of full when/when-not guidance.

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