version: "1.0.0" name: plan-on-disk description: Keep the active plan on disk instead of in the context window — task_plan.md, findings.md, progress.md — so it survives /clear, compaction, crashes, and hour ten of a long run. Use when starting multi-step work expected to outlast one sitting or one context window, resuming after a /clear or compaction, when work drifts from the original intent after many tool calls, or when handing a long-running task to an agent or subagent chain. Skip for short tasks that fit in one sitting and never leave the session.

Read the file matching the model actually running before applying this skill.

Running a model not listed above (an older generation, a different model family entirely)? sonnet-5.md carries the fullest general-purpose version of the underlying procedure — read that one rather than skipping this skill.
