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; the description is consistent with them and adds real value by stating the tool 'opens nothing by itself' and that actual execution must happen through cotlet_browser_* tools. The note that no public EZ Lawn Biller API exists explains why the browser route is required. What's missing is what the returned guidance looks like in practice (length, format, whether it varies by account state).

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 critical behavioral fact — that this returns instructions rather than performing the action — is buried in the second sentence behind a misleading opener. The API-availability digression (404 URLs, QuickBooks-only FAQ) is longer than needed to make the point and pushes the actionable content back.

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 output schema, the description carries the burden of saying what comes back, and it does: step-by-step screens, buttons and fields. The follow-on path (use cotlet_browser_* tools) closes the loop. Minor gaps remain around error conditions or what happens if the account UI differs from the documented steps.

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 and the baseline of 4 applies. The description correctly implies no input is needed, 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 second sentence makes the actual function explicit: it returns step-by-step instructions (screens, buttons, fields) for the 'Copy to Future Weeks' task and performs nothing itself. The opening sentence is muddled, though — 'Copy to Future Weeks in the user's own EZ Lawn Biller account' reads like the tool performs the copy, which is only corrected later. It also does not distinguish itself from siblings such as ez_lawn_biller_apply_to_all_weeks or ez_lawn_biller_future_week_changes.

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 give a clear workflow: call this for guidance, then execute with the cotlet_browser_* tools in the EZ Lawn Biller Cloud Browser. However, there is no guidance on when to pick this over related siblings (apply_to_all_weeks, future_week_changes), and no statement of prerequisites such as having a Cloud Browser session connected.

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