Maintain tasks/context.md as a living, durable "what matters" record for the project. Write it for someone taking over the project (or a future session resuming later). Explain where things are, what was decided, and what to watch before proceeding.
Treat this as shared behaviour embedded in other skills, not a mandatory standalone step in normal workflows. When invoked inline (from another skill), apply this workflow as part of that skill's execution.
When invoked directly, use for explicit backfill/repair/cleanup requests.
Maintain durable project context in `tasks/context.md` (state, decisions, milestones, gotchas, optional context links), inline during other workflows or standalone for cleanup/backfill. Triggers: update context.md, decision log, record project context, capture high-value reference links that improve context handoff. Source: kelvinz/cobb.
