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

Annotations (readOnlyHint=true, idempotentHint=true) already say nothing is mutated, and the description reinforces this with 'opens nothing by itself' while adding the crucial dependency that execution must happen via cotlet_browser_* tools. It does not describe what a failure or missing-page scenario looks like, so it stops short of full transparency.

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 operational content is front-loaded and useful, but the trailing sentence about PeopleHR's REST API and the absence of an official MCP server (with a check date) is justification trivia that does not help an agent decide or invoke. Roughly a third of the text is background rather than instruction.

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, no-output-schema guidance tool, the description conveys what comes back (step-by-step screens, buttons, fields) and what must follow it. The only gap is that it does not state the shape or granularity of the returned instructions beyond that phrase.

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 baseline of 4 applies. The description does not need to explain parameter meaning and appropriately does not try.

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?

Despite a name that suggests a write operation, the description makes the actual function explicit: it 'Returns how to do it in PeopleHR step by step (screens, buttons, fields) and opens nothing by itself.' That distinguishes it from a true task-creation tool and from the sibling browser tools, though the mismatch between name and behavior costs it a point.

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 prescribes a concrete two-step workflow: call this to get the PeopleHR walkthrough, then execute with the cotlet_browser_* tools in the user's PeopleHR Cloud Browser. There are no explicit when-not conditions or named alternatives among the other peoplehr_* siblings, but the sequencing guidance is actionable.

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