# Context Handoff ## Why this exists Long sessions accumulate context that isn't relevant to every sub-goal that arises. Two failure modes follow: model attention degrades as the session grows, and doing a subtask inline leaves residue that distracts from the main thread. A fresh context fixes both — but rebuilding that context by hand is slow and error-prone. This skill has the current session (which already understands what matters right now) author a self-contained, paste-ready brief for the new context. The skill supplies the technique and output shape; the session supplies the judgment about what to include. ## When to use this vs. the Task tool For in-session parallel work where results flow back automatically, use the Task tool / subagents — they solve that problem more completely. Reach for this skill when the handoff crosses a boundary the harness won't bridge: a brand-new session, a spawned background task you'll paste a result back from, a human teammate, or an issue/ticket. The deliverable is portable text someone (or some fresh instance) can act on with zero prior context. ## Three modes **Subtask** — a bounded piece of work is spun off and returns an artifact (a script, a draft, a piece of analysis, a list) that gets pasted back to inform ongoing work. Narrow context slice. The executor is a helper producing a deliverable, not a peer you'll keep working with. **Fork** — the current state is exported into a new context that continues the work independently
