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

With no annotations, the description carries full burden. It discloses that cookies are added to the 'current browser context' and returns a status/count, which is useful behavioral context. However, it doesn't mention potential side effects, permissions needed, or error conditions, leaving gaps for a mutation tool.

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 description is appropriately sized and front-loaded with the core purpose, followed by structured sections for args and returns. However, the 'Args:' and 'Returns:' labels could be more integrated, and some redundancy exists (e.g., repeating 'cookies').

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 no annotations and no output schema, the description provides basic purpose and parameter details but lacks information on error handling, browser context requirements, or interaction with sibling tools. For a mutation tool in a browser automation context, this is minimally adequate but has clear gaps.

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 description coverage is 0%, but the description compensates fully by detailing the 'cookies' parameter: it's a list of dicts with minimum required fields (name, value, domain) and optional ones (path, expires, etc.). This adds significant meaning beyond the bare 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 description clearly states the verb 'Add' and resource 'cookies to the current browser context', making the purpose specific and actionable. However, it doesn't explicitly differentiate from sibling tools like 'delete_cookies' or 'get_cookies', which would require a 5.

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?

No guidance on when to use this tool versus alternatives like 'delete_cookies' or 'get_cookies' is provided. The description implies usage for adding cookies but lacks context on prerequisites, exclusions, or comparisons to sibling tools.

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