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

The description adds real information beyond the annotations: it explicitly says it 'opens nothing by itself,' which reinforces the readOnly/no-side-effect profile while telling the agent what to expect (screens, buttons, fields as text). It also notes Mangomint has no public API or developer docs, explaining why a guided-browser path is the route. Minor gap: no detail on output length or format beyond the parenthetical.

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 opening clause listing 'ChatGPT, Claude or any AI agent' is marketing filler that does not help tool selection. The dated verification note ('checked 11 Oct 2026') is unusual and somewhat distracting, though it does support the no-API claim.

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 parameters, no output schema, and simple read-only annotations, the description covers everything an agent needs: what it returns, that it performs no action, and which tool family executes the steps. Nothing material is missing for a guidance-style tool.

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 there is nothing for the description to disambiguate; the baseline for a no-param tool applies. The description correctly implies no inputs are needed, since it returns generic instructions.

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 names a specific verb and resource ('find client in the user's own Mangomint account') and then corrects the likely misreading by explaining it returns step-by-step instructions rather than performing the search. That distinction separates it from the cotlet_browser_* action tools without naming a single sibling. The only wrinkle is that the name suggests the search is performed, so the correction has to carry extra weight.

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 workflow clearly: this tool produces the steps, and 'then do it with the cotlet_browser_* tools in the user's Mangomint Cloud Browser.' That is actionable context with an explicit handoff. It does not name a specific alternative for the actual lookup (e.g. cotlet_browser_find), so routing between the two relies on inference from the tool family prefix.

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