Gate — harness-portable quality gate

!IMPORTANT: Follow this process exactly. Do not skip steps.

This skill is a gate, not a fixer. It returns a verdict; it does not modify code.

It orchestrates with a single primitive every agent harness has: spawn a subagent, read its result. No Workflow tool, no agent teams — so it runs unchanged on Claude Code and Codex. The companion gate-wf skill runs the same review logic on the Claude Code Workflow engine (deterministic static script, --resume caching); prefer it when Workflows are enabled.

Skill version: 5. Cache entries are keyed on this — bumping invalidates all caches at once.

Prerequisites

• A harness with a subagent primitive (Claude Code Agent/Task tool, Codex subagents). Reviewer subagent types (bug-reviewer, solid-reviewer, … skeptic, context-checker) ship with this plugin at the plugin root agents/*.md — they are the single source of the review logic, shared with gate-wf.
• The reviewer skill dependencies of Step 0.
