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

Beyond the annotations, the description discloses the crucial trait that the tool has no side effects and returns procedural guidance rather than data ('opens nothing by itself'), and it names the screen/button/field granularity of the return. The note that Freshchat has a REST API v2 but no official MCP server explains why a browser-based path is used. This is meaningful context an agent could not derive from readOnlyHint/idempotentHint alone.

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 behavioral fact is buried in the middle of the first sentence's run-on construction, and the opening phrase 'from ChatGPT, Claude or any AI agent' is marketing filler that earns no place. The trailing API/MCP-availability note is contextually useful but reads as a disclaimer appended after the actionable content.

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 full annotation coverage, the tool is simple and the description covers the mechanism and the next step. Still missing is what the response actually looks like (a single guide block? per-response steps?) and what happens if the user has no active Freshchat browser session, which matters because the follow-up depends on it.

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 input schema declares zero parameters with additionalProperties false, so there is nothing for the description to disambiguate. Baseline for a zero-parameter tool is 4, and the description correctly implies no inputs are needed.

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 name and title promise a listing of canned responses, but the description says the tool actually returns 'how to do it in Freshchat step by step (screens, buttons, fields)' and 'opens nothing by itself'. That behavior is stated, but it takes three sentences to discover and it conflicts with the advertised name, so an agent skimming the title will mispredict the output. It also does not differentiate this from sibling freshchat_* tools, which likely follow the same guide-then-browse pattern.

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?

The description does route the agent forward: after calling this, 'do it with the cotlet_browser_* tools in the user's Freshchat Cloud Browser'. That implies a two-step workflow. However, there is no explicit statement of when to call this versus going straight to cotlet_browser_navigate, and no prerequisites such as the user needing an authenticated Freshchat browser session.

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