cookie_import_file

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether importing replaces existing cookies, merges with them, or requires an active browser context. This is a meaningful gap for a state-mutating operation.

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 a single concise sentence with no filler. It front-loads the action and source, and the format qualifier is placed meaningfully at the end.

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 low complexity and single parameter, the description covers the essential input. However, without annotations or an output schema, it omits the overwrite/merge side effects and does not clarify how this tool relates to cookie_import, leaving moderate 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?

The schema already fully documents the path parameter at 100% coverage, so the baseline is 3. The description adds value by clarifying that the file content must be in Playwright cookie JSON format, which is important for correct invocation.

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 action ('Import cookies') and resource ('a JSON file'), and adds the Playwright format constraint. It is clear, though it does not explicitly differentiate itself from the sibling cookie_import tool.

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 implies the tool should be used when cookies are available as a Playwright-format JSON file path. However, it provides no explicit guidance about when to prefer this over cookie_import or cookie_export_file, and no exclusions are stated.

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