browser_set_session_name

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

The description discloses that the name appears on the Chrome tab group, which is behavioral information not in the schema. Since no annotations are provided, this covers the full burden adequately.

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?

Three sentences, each with clear purpose: what the tool does, where the name appears, and when/how to use it. No unnecessary words, highly efficient.

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?

Given the tool's simplicity (one parameter, no output schema), the description fully covers the necessary information for correct usage, including examples and placement.

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%, so baseline is 3. The description adds meaning by specifying the name should be a short task summary and that it will appear on the tab group, enriching the understanding of the parameter beyond the schema description.

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 clearly states the tool sets a descriptive name for a browser session, distinguishing it from sibling tools like browser_click or browser_navigate which perform actions. It specifies the resource (browser session) and the action (set name).

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 description advises calling this early with a short task summary and provides examples, giving clear usage context. It does not explicitly mention when not to use or alternatives, but for a simple tool this is sufficient.

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