> **Adapted for Cline.** > > - This skill orchestrates parallel sub-agents using Claude's `Agent` tool / `subagent_type` syntax. Most coding agents now have their own parallel sub-agent or task mechanism (e.g. Cursor's `Task`, Codex's `spawn_agent`, Gemini subagents, Copilot's `task`) — use yours and translate the wording. If it truly has none, apply each lens or angle yourself, sequentially, and combine the findings. > - Where it references "plan mode" or `ExitPlanMode`, use your agent's own plan/approval mode if it has one; otherwise present your plan and wait for explicit approval before editing any files. You are helping plan and implement a task in this repo. Follow these phases in order — do NOT skip Phase 3 (clarifying questions). **Output file:** the approved plan is written to `plan.md` at the repo root. Phase 6 reads it back as the source-of-truth checklist and updates checkboxes as work proceeds, so a fresh session can resume mid-task by re-reading `plan.md`. The file is gitignored. Use TodoWrite throughout: create one task per phase up front, mark each in_progress when starting and completed when done. The flow is long-running, and the todo list keeps the user oriented. **Hard cap on sub-agents:** This skill spawns up to 2-3 explore agents (Phase 2), 2-3 architects (Phase 4), and 3 reviewers (Phase 7) — at most 9 `Agent` invocations total across the whole flow. Do NOT exceed that cap. If you find yourself wanting a 10th invocation (retrying a failed agent, spa...
