What problem does it solve? Coordinating multi-agent software development across a whole project is usually improvised ad hoc: agents edit the same checkout, worker summaries get trusted as acceptance evidence, and nobody tracks what was actually verified. This Skill provides a repeatable Frame-to-Ship loop with a Seeds queue of record, isolated Git worktrees per workstream, and evidence-backed acceptance rules. ## Core Features & Use Cases - Phased SDLC loop: Frame, Discover, Research, Plan, Act, Review, Reconcile, and Ship phases with bounded backflow and hard stops for unsafe operations. - Seeds-backed worktree waves: A pinned, receipt-verified Seeds CLI acts as the queue of record while each write-capable worker runs in its own .worktrees/<seed-id>-<slug>/ worktree. - Provider-native delegation: Routes work to Claude Code subagents/workflows, Codex role agents, or direct execution, with cmux as an optional view/event layer only. - Use Case: You open a repository with a backlog of open seeds and ask the agent to drive it to zero; the Skill frames the mission, fans out implementers into worktrees, requires independent review and a re-run gate on the merged snapshot, and records wave evidence before any PR is proposed. ## Quick Start Ask the agent to run the agentic SDLC loop on this repository, starting with activation via /sdlc-init if no Seeds queue exists, then framing and executing the next ready seed in a worktree wave.
