cross-agent-phase-gate

Use when Codex should execute a written multi-phase implementation plan one bounded phase at a time while Claude acts as PM, design architect, and audit gate. In Codex, this skill defaults to `codex_builder_claude_reviewer`. The same shared system also supports the reverse direction from Claude terminals.

Execute a written multi-phase implementation plan through the shared phase-gate daemon. In Claude, this skill defaults to `claude_builder_codex_reviewer`: Claude builds one bounded phase at a time and Codex acts as PM, design architect, and audit gate. The same shared system also supports the reverse direction from Codex terminals.
