crewnest_open

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

With no annotations, the description carries the burden itself. It usefully discloses that the page opens in the 'signed-in Cloud Browser', which tells the agent the session is authenticated and no credentials are needed. However, it says nothing about what happens on navigation (return value, whether it waits for load, behavior if a page is already open).

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 front-loaded sentence with the action first. The trailing purpose clause ('work with prepare estimates and manage jobs and crew assignments') is somewhat padded and awkwardly phrased, but it does not obscure the core instruction.

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-optional-parameter navigation tool with no output schema, the definition covers the essentials. It leaves open what the agent gets back after opening (confirmation vs. page content) and whether a follow-up read is expected, which matters for chaining with crewnest_read and crewnest_click.

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?

Schema coverage is 100% and the single parameter's default is documented in the schema itself, so the description's mention of the default URL adds no new meaning. Baseline of 3 applies; nothing about format or constraints is added.

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?

Uses a specific verb+resource ('Open a CrewNest page') and names the browser context. It implicitly distinguishes itself from siblings like crewnest_click, crewnest_type, and crewnest_close as the entry/navigation tool, though it never names an alternative explicitly.

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 purpose implies when to use it (navigating to a CrewNest page before acting), but there is no explicit when-to-use framing, no prerequisites, and no statement about how it relates to the sibling tools that operate on the opened page.

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