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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description goes further by stating the action is PERMANENT and irreversible, which is a sharper consequence than the hint alone conveys. It still omits side effects on the losing video(s) and any permission requirements.

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?

Two short sentences, front-loaded with the action and the irreversibility warning. Every word earns its place; nothing is padding.

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?

For a destructive terminal operation with no output schema, the description covers the action and its permanence but not what actually happens to the comparison record, the losing video, or analytics results — details an agent may need to warn the user about.

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 100% with only two required parameters, so the schema fully documents comparison_id and winner_video_id. The description adds nothing about parameter meaning, but baseline 3 is appropriate when the schema does the work.

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 ('Finish') and resource ('A/B test'), plus the concrete outcome ('declare a winner'). This clearly distinguishes it from siblings like panda_start_comparison, panda_create_comparison, and panda_delete_comparisons.

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?

Usage is only implied: an agent can infer this is the terminal step of an A/B test after panda_start_comparison. No explicit condition (e.g., 'only after the test has run long enough'), no prerequisites, and no named alternative for other comparison operations.

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