> **Platform Note:** Project agents live in `<state-dir>/agents/` where `<state-dir>` is `.claude/` (Claude Code), `.codex/` (Codex CLI), `.cursor/` (Cursor IDE), or `.pi/` (Pi). On Cursor IDE and Pi v1, parallel agent dispatch is not available — present wave tasks as a sequential execution list instead. See `skills/_shared/platform-tools.md`. # Session Plan Skill > Project-instruction file resolution: `CLAUDE.md` and `AGENTS.md` (Codex CLI) are transparent aliases — see [skills/_shared/instruction-file-resolution.md](../_shared/instruction-file-resolution.md). Wherever this skill mentions `CLAUDE.md`, the alias rule applies. ## Phase 0.5: Parallel-Aware Preamble > Skip silently when `persistence: false` in Session Config. Before any Phase 1 work, 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 either: - Returns `PASS_THROUGH` (no other session / `always-ok` mode) → continue to Phase 1 - Returns `EXCLUSIVE_BLOCKED` → fires Exclusive-Conflict AUQ from `skills/_shared/parallel-aware-auq.md` - Returns `PROMOTION_OFFER` → fires Worktree-Promotion AUQ (via `enterWorktree()` from `scripts/lib/autopilot/worktree-pipeline.mjs` — see `parallel-aware-auq.md` outcome-handling) On any non-PASS_THROUGH outcome that does not result in immediate exi...
