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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false. The description goes beyond them by disclosing the return shape (step-by-step screens/buttons/fields) and that the tool 'opens nothing by itself', which is the key behavioral fact an agent needs to avoid assuming an action occurred. The API-availability note adds further context about why browser automation is the path.

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 behavior is front-loaded, which is good, but 'from ChatGPT, Claude or any AI agent' is filler, and the closing paragraph on 404s at /api, /developers and /docs plus the QuickBooks FAQ detail is more verbose than an agent needs to act. The essential points could be stated in roughly half the words.

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 and no output schema, the description carries the burden of explaining what comes back, and it does so (step-by-step instructions rather than a preview). It also explains the handoff to the browser tools. A brief note on what happens if the account is not connected would close the remaining 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 there is no parameter meaning to convey; the baseline of 4 applies. The description correctly implies no input is required, consistent with the empty 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?

The description states a specific resource (notice preview) and then clarifies the actual behavior: it 'Returns how to do it in EZ Lawn Biller step by step (screens, buttons, fields) and opens nothing by itself.' That resolves the ambiguity in the name. It does not differentiate from near-siblings such as ez_lawn_biller_notice_dry_run or ez_lawn_biller_preview, which keeps it below a 5.

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 does route the agent forward, saying to 'do it with the cotlet_browser_* tools in the user's EZ Lawn Biller Cloud Browser', which is a real usage instruction. However, it never states when to pick this over notice_dry_run, notice_templates, or the plain preview tool, so the alternative-selection guidance is only partial.

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