# Contents
- - `SKILL.md` – portable Codex workflow for executing phased implementation plans with delegated lanes and join gates.
+ - `SKILL.md` – parent workflow for delegated phased implementation, validation, review, and integration.
- `agents/` – Codex UI metadata for discovering and invoking the skill.
+ - `LICENSE` and `UPSTREAM.md` – license and pinned provenance for the complete five-skill pack.
# Guidelines
- - Keep orchestration instructions specific to Codex collaboration tools and defer repository commands, validation, version control, and delivery authority to the repository's own guides.
- - Preserve the root agent as the owner of shared interfaces, convergence files, integration, validation, and delivery.
- - Keep repository-owned execution plans in `kb/plans/`; use lane-safe KB checks during fan-out and the refresh-check workflow at integration.
+ - Keep the orchestrator aligned with `write-phase-plan`, `phase-implementer`, `phase-reviewer`, and `phase-final-reviewer`.
+ - Preserve the parent agent as the owner of phase state, repository policy, shared integration, validation, commits, and delivery.
+ - Keep host-specific tool names conditional and defer repository commands and authority to the target repository's guides.
- Update `agents/openai.yaml` when the skill name, trigger, or default invocation changes.
