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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true and openWorldHint=false, and the description is consistent with that by stating it "opens nothing by itself" and operates on "the user's own Chatwoot account." It adds useful context about the return shape (step-by-step screens, buttons, fields) and the required Cloud Browser dependency, but the closing note on Chatwoot's REST API and lack of an official MCP server is background rationale rather than behavior an agent needs.

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 two sentences are well front-loaded and do real work, but the third sentence about Chatwoot's official API, Application API, command-line client and a dated "checked 22 Oct 2026" note is tangential and lengthens the definition without helping the agent decide or invoke. "From ChatGPT, Claude or any AI agent" is also filler.

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 guide tool with no output schema and annotations covering the safety profile, the description supplies what matters: that it returns instructions rather than acting, what form those instructions take, and which tools execute them. The absence of any hint about what the returned guidance covers (e.g., agent vs. team assignment) is the only notable 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 schema carries nothing to interpret and the baseline of 4 applies. The description adds no parameter detail, which is appropriate here.

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 the resource and action ("Assign conversation in the user's own Chatwoot account") and then clarifies the actual mechanic: it "Returns how to do it in Chatwoot step by step (screens, buttons, fields) and opens nothing by itself." That clarifies the gap between the name and behavior, though the leading verb still reads like a mutation until the second sentence corrects it, and it does not distinguish itself from chatwoot_reply_to_conversation or chatwoot_add_labels.

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 gives a concrete workflow: call this to get the screens/buttons/fields, then "do it with the cotlet_browser_* tools in the user's Chatwoot Cloud Browser." That tells the agent both when this tool applies and which tools complete the job, but it names no exclusions and never contrasts with the other chatwoot_* action siblings.

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