# Session Context Rebuild You're returning to work that spans multiple sessions — possibly conflicting ones. The context window is empty but the walnut isn't. This skill dispatches subagents to deeply reconstruct what happened, what changed, where conflicts exist, and what the merged state should be. Then you resume with full context as if you never left. --- ## When to Use - Returning to a walnut after days/weeks away - Context was lost to compaction mid-session - Multiple sessions touched the same walnut in parallel and need merging - Picking up someone else's work in a shared walnut - "What was I doing here?" moments --- ## Process ### Phase 1: Scout (single agent) Dispatch one `general-purpose` subagent to map the territory. It reads the `session-history/SKILL.md` file and applies its browse logic against `.alive/_squirrels/`, then reports back: - Which sessions touched this walnut, when, by whom (engine) - Which files each session worked on (`working:` field in squirrel YAML) - Which bundles were active - Whether sessions overlap (parallel/conflicting work) - Unsaved stash items from crashed sessions **Cross-walnut detection:** the scout performs two queries, not one: 1. **Walnut-tagged match** — squirrel YAMLs where `walnut: {target}` (the obvious set) 2. **Routed-stash match** — squirrel YAMLs where any stash item's `routed:` field contains the target walnut name (catches maintenance sessions with `walnut: null` that routed work to this walnut) Merge-dedupli...
