Diff Review
Review everything that differs from main across 9 perspectives, each by one subagent. The nine areas' findings then run through the same scripted collate, merge, rank, and isolated-judge verification chain review-deep uses. No arguments.
Available on Claude Code (through this plugin) and Codex. Fails preflight by name on OpenCode and Hermes Agent, neither of which can dispatch a subagent to a named reviewer type.
This skill runs context: fork, dispatched as a subagent with no user present to answer a prompt. Never pause before dispatch to confirm scope, cost, or model spend; the diff is whatever it is.
Step 1: Preflight
Determine your harness. In Claude Code, HARNESS=claude and PLUGIN_ROOT is this plugin's root, two directories up from this SKILL.md. In Codex, HARNESS=codex; PLUGIN_ROOT does not apply there, since the nine Codex reviewer agents live at a fixed path, not inside a plugin.
