# Session End Skill > **Platform Note:** State files (STATE.md, wave-scope.json) live in the platform's native directory: `.claude/` (Claude Code), `.codex/` (Codex CLI), `.cursor/` (Cursor IDE), or `.pi/` (Pi). All references to `.claude/` below should use the platform's state directory. Shared metrics live in `.orchestrator/metrics/`. See `skills/_shared/platform-tools.md`. > **Project-instruction file:** `CLAUDE.md` and `AGENTS.md` (Codex CLI) are transparent aliases — see [skills/_shared/instruction-file-resolution.md](../_shared/instruction-file-resolution.md). All references to `CLAUDE.md` in this skill resolve via that precedence rule. ## Phase 0: Bootstrap Gate Read `skills/_shared/bootstrap-gate.md` and execute the gate check. If the gate is CLOSED, invoke `skills/bootstrap/SKILL.md` and wait for completion before proceeding. If the gate is OPEN, continue to Phase 1. <HARD-GATE> Do NOT proceed past Phase 0 if GATE_CLOSED. There is no bypass. Refer to `skills/_shared/bootstrap-gate.md` for the full HARD-GATE constraints. </HARD-GATE> ## Phase 0.5: Parallel-Aware Preamble > Skip silently when `persistence: false` in Session Config. Before Phase 1, run the parallel-aware preamble per `skills/_shared/parallel-aware-preamble.md`. The preamble detects other active sessions in the worktree-family via `findPeers(repoRoot, { mySessionId })`, classifies the caller's mode via `classifyMode(callerMode)` against the exclusivity-matrix, and fires the appropriate AUQ on con...
