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

Beyond the readOnly/idempotent annotations, it discloses the critical behavioral fact that the tool "opens nothing by itself" — it only returns instructions — which an agent could not infer from the annotations or the empty schema. It also notes the fallback mechanics (cotlet_browser_* in the user's Angi Cloud Browser) and the absence of a public Angi API.

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 facts (what it returns, that it opens nothing, the follow-up tool family) are front-loaded and useful. However, "from ChatGPT, Claude or any AI agent" is marketing filler and the "(checked 28 Oct 2026)" editorial note does not earn its place in a tool 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 parameters, no output schema, and annotations already covering the safety profile, the description supplies the one thing that matters: it is a guide-returning tool, not a data-fetch tool, and the actual work happens via cotlet_browser_*. Minor gap around the exact shape/length of the returned instructions.

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?

Zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. The description correctly implies no input is required, consistent with the empty object schema.

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 ("List reviews in the user's own Angi account") and scopes it to the caller's own account, distinguishing it from siblings like angi_reply_to_review. It then clarifies the tool returns step-by-step instructions rather than data, which conflicts slightly with the "List reviews" name, but the actual behavior is explicitly stated.

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?

Explicitly gives the workflow: this tool returns the screens/buttons/fields, then the agent must act with the cotlet_browser_* tools in the Angi Cloud Browser. Clear routing to the alternative tool family, though it never states when NOT to use this versus a direct cotlet_app_guide call.

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