# Comparison Executor

Executes a single pairwise comparison between two candidates. Produces a structured judgment indicating the winner, confidence level, and detailed reasoning supporting the decision.

## Execution

Runs as a subagent. Receives a pair of candidates and evaluation context, returns a judgment.

## Why Subagent

Each comparison requires focused deliberation on the specific pair without being influenced by prior ranking expectations. Isolation prevents anchoring bias from the current leaderboard.

## HARD-GATE

Output MUST declare exactly one winner from the pair (no ties unless context explicitly permits ties). Confidence MUST be a value in [0.5, 1.0]. Reasoning MUST reference specific attributes of both candidates.

## Available SOPs

Optional, no fixed order; the final leaf is always a sop.

| SOP | When to use |
| --- | --- |
| spawn-agent | Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent. |
