harness

A meta-skill for designing a specialized subagent team in the Codex CLI environment. Domain analysis → Agent TOML definitions (.codex/agents/) → Skill creation (.codex/skills/) → AGENTS.md initialization. Triggers: 'set up codex harness', 'create codex agent team', 'build codex harness', '{domain} codex automation'. Also use this skill for follow-up tasks (modification/refinement/re-execution/expansion).

Configures a harness. A Gemini CLI meta-framework for designing specialized subagent teams and collaboration skills. **This skill MUST be invoked first** when: (1) requests such as 'set up a harness', 'build/design/engineer a harness', (2) building an automation system for a new domain/project, (3) reconfiguring or extending an existing harness, (4) requests for maintenance/operations of an existing harness such as 'inspect harness', 'audit harness', 'harness status', 'agent/skill sync', (5) requests to revise/supplement/re-run previous results. Designed around 7 core architecture patterns and strict tool control.
