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

Beyond the annotations it discloses the key behavioral fact that "opens nothing by itself," so the agent knows no side effect occurs, and it explains why browser automation is required (the official OData API is read-only). This is consistent with readOnlyHint=true and adds real context. Minor gap: it doesn't describe the shape or length of the returned step-by-step text.

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 message is front-loaded, but the text is a rambling run-on that stitches three ideas together with semicolons, and the closing API sentence is a fragment ("MarketSharp's official API: MarketSharp has a read-only OData API..."). The API detail earns its place as justification but could be one clause instead of two.

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 zero parameters, no output schema, and a simple read-only guidance behavior, the description covers what an agent needs: what it returns, that it has no side effects, and which tools to use next. Only the return format of the instruction text is left unspecified, which is a small 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 the baseline is 4 and the description has nothing parameter-related it must compensate for. Nothing here adds confusion about inputs.

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 gives a specific verb and resource ("Create lead in the user's own MarketSharp account") and immediately clarifies that the tool does not actually create anything but returns step-by-step instructions. This resolves the tension with the name, though the name itself still reads like a mutating action, which costs 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 states the follow-up path explicitly: after receiving the steps, execute them "with the cotlet_browser_* tools in the user's MarketSharp Cloud Browser." That routes the agent to the right sibling family. It does not, however, say when to prefer this over cotlet_app_guide or cotlet_apps, both of which plausibly overlap.

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