zerodom_adopt_group

Adopt an existing Chrome tab group by title, making it the agent's active sandbox so you can pre-arrange tabs and scope the agent to exactly them.

Instructions

Hand an existing Chrome tab group (that you created yourself, by title) to the agent: it joins the agent's sandbox and becomes the active group. Lets you pre-arrange tabs and then scope the agent to exactly them.

B3.4/5.0

Behavior3/5

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

No annotations, so the description carries the full burden. It does disclose meaningful behavior (the group joins the sandbox and becomes the active group) and a precondition (must be a group you created yourself, referenced by title). However, it omits side effects like what happens to the previously active group and any permission or failure conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, front-loaded with the core action and outcome. No filler, though the parenthetical precondition slightly interrupts the flow.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values need not be explained, but with no annotations and a 0%-covered required parameter, the description leaves gaps around side effects and matching semantics. Adequate for invoking the tool, thin for predicting its behavioral footprint in the group-management workflow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% for the single 'name' parameter, so the description must compensate. The phrase 'by title' clarifies that name is the group's title, which adds real meaning, but no format, case-sensitivity, or matching behavior is specified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: 'adopt' an 'existing Chrome tab group' and describes the outcome (joins the agent's sandbox, becomes the active group). Clear enough to distinguish from create_group/close_group, though it never contrasts with the very similar-sounding zerodom_use_group, leaving some ambiguity in the group-management cluster.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies the scenario ('pre-arrange tabs and then scope the agent to exactly them') but gives no explicit when-to-use vs when-not, and never names an alternative such as use_group or create_group. Usage is inferable but not spelled out.

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