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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, and the description stays consistent while adding the non-obvious fact that the tool "opens nothing by itself" and returns procedural guidance instead of data. The note that PeoplePerHour has no public API explains why a browser-driven approach is required, which is genuine context beyond the annotations. It omits prerequisites such as whether a Cloud Browser session or credits must exist first.

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 single dense sentence-chain buries the most decision-relevant fact — that this returns instructions, not search results — behind marketing framing ("from ChatGPT, Claude or any AI agent"). The dated API footnote is useful but could be tightened; the description would be stronger front-loading "returns a step-by-step guide, performs nothing."

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 parameters and no output schema, the description carries the burden of explaining what comes back, and it does: screens, buttons, and fields for the PeoplePerHour workflow. It is nearly complete, missing only session/prerequisite conditions for the handoff to cotlet_browser_* tools.

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 is 4 and there is nothing for the description to disambiguate. It adds no parameter meaning because none exists, which is appropriate rather than deficient.

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?

States a specific verb and resource ("Search freelancers") scoped to "the user's own PeoplePerHour account," and the second sentence clarifies the crucial twist that it returns step-by-step instructions rather than results. It distinguishes itself from the cotlet_browser_* siblings by positioning them as the execution layer, though it never contrasts itself with peopleperhour_search_projects/search_offers or 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?

Gives a clear operating sequence: call this to get the screens/buttons/fields, then perform the action with the cotlet_browser_* tools in the PeoplePerHour Cloud Browser. It does not state exclusions or when a different tool (e.g., cotlet_app_guide) would be preferable, so it stops short of a full when/when-not treatment.

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