load_cookies

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

No annotations provided, so the description carries the full burden. It doesn't disclose what happens to existing session cookies, whether loading overwrites state, required permissions, or any error/format behavior. Only the basic mutation operation is implied.

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?

A single, front-loaded sentence that states the action, source, and destination without waste. Appropriately sized for a simple operation, though it lacks routing/behavioral detail.

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?

The tool is simple (1 optional param) and has an output schema, so return values needn't be explained. However, with no annotations and 0% param coverage, an agent lacks the behavioral context (overwrite semantics, path format) needed to call it confidently.

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%, and the single 'path' parameter defaults to an empty string with no documentation. The description mentions 'from a JSON file' but doesn't explain the path format, whether it's absolute/relative, or what an empty default implies. Partial compensation, baseline-ish.

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?

States a specific verb+resource ('Загрузить куки' = load cookies) and target ('в текущую сессию'). It is distinguishable from the sibling 'save_cookies', though it doesn't explicitly name it.

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 when-to-use guidance, no prerequisites, no exclusions, and no mention of the complementary 'save_cookies' tool that clearly pairs with this one. The agent gets no routing help.

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