setmore_open

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

No annotations are provided, so the description carries the full burden. It does disclose one genuinely useful behavioral fact: the page opens in the user's already signed-in Cloud Browser session, so no authentication step is needed. It says nothing about whether an existing tab is reused, what happens on failure or an invalid URL, or what the caller gets back after navigation, which matters for a tool with zero annotation coverage.

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?

One sentence, front-loaded with the verb and resource, with the default URL given parenthetically. Nothing is redundant, but the closing clause is awkwardly worded ('to work with manage appointments') and could have been spent on routing information instead.

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 one-parameter navigation tool with no output schema, the description covers the essentials: what opens, where, and in what session. It stops short of describing the post-open state or the sequencing with the sibling interaction tools, which is the main thing an agent needs to chain calls correctly.

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?

There is a single optional parameter and schema description coverage is 100%, with the schema itself documenting 'Page to open. Default: https://setmore.com'. The description merely restates that default value. No added meaning about accepted URL forms (relative paths vs. full URLs, allowed domains) is provided, so the baseline of 3 applies.

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 verb and resource: 'Open a Setmore page in your signed-in Cloud Browser.' That clearly separates it from setmore_close and the interaction tools (click/type/read), though it never names a sibling explicitly. The trailing purpose clause ('to work with manage appointments, customers and staff calendars') is grammatically garbled and adds little precision about scope.

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?

Usage is only implied: an agent can infer this is the navigation entry point that must precede setmore_click, setmore_type and setmore_read, but the description never says so. There is no explicit when-to-use, no when-not-to-use, and no reference to alternatives such as setmore_status or setmore_guide. The purpose clause hints at the context (working with appointments/customers/calendars) without turning it into guidance.

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