# Implement Plan With Subagents Orchestrate the autonomous, plan-driven, multi-subagent implementation of a plan artifact. This skill is the orchestrator role: it does not write code itself — it reads the plan's index READ-ONLY (and the artifact its `Source:` line names), walks the index's task list in order, dispatches an **implementer subagent** for each task, dispatches ONE **merged reviewer subagent** that loads both review method files and returns two lane verdicts (plan-compliance and code-quality) judged independently, respawns a NEW implementer subagent whenever either lane surfaces issues, re-reviews every fix before advancing, commits per orchestration cycle, appends every attempted task's factual progress block to the run's progress file (cycle-gated, not commit-gated), and updates the thread's singleton **implementation report** on the way out. It does not pause for clarifying questions at each step and does not ask before committing; the execution posture is identical whether or not a person is present. It does not rewrite history. ## Subagent Capability Precondition **This skill REQUIRES subagent capability** (e.g., a runtime primitive that lets the orchestrator spawn an independent subagent with its own context window and have it write files to disk before replying with an acknowledgment). The orchestrator role this skill defines is meaningful only when implementer and reviewer subagents are real, separate-context dispatches. **This skill does NOT fall back
