Session Resume Skill

Goal

Allow ANY agent at ANY time to load the complete project state and continue as if they were there from the beginning. Zero knowledge loss between sessions. Always run integrity-check before continuing to verify current state.

Boot order: this skill is the memory-load step that preflight.skill delegates to on a cold start / resume — it does not call preflight back. Canonical order: preflight → integrity-check → session-resume (here) → return to preflight for the capability summary. (See preflight.skill.)

Steps

Load PROJECT_STATE.md (primary state file)
- Read: agents/memory/PROJECT_STATE.md
- Determine: current lifecycle phase — any of S00–S13 (Day-0 S00, core build loop S01–S10, Day-2 S11–S13). S00 and S11–S13 are real phases; resume into them, do not skip them.
- Note: last checkpoint, last completed milestone, current blockers
