The proposed solution, 'context anchoring', externalizes feature-level decision context into a living document updated throughout development. Unlike project-level priming documents, this feature document captures specific decisions, their rationale, rejected alternatives, open questions, and implementation state. It enables warm-start sessions, coordinates multiple developers sharing AI sessions, and preserves the 'why' behind decisions that automated context compaction silently discards. A practical example with a notification service shows how a sub-50-line document replaces 45 minutes of context reconstruction. The approach is calibrated to effort: lightweight capture for single-session work, full documents for multi-day or multi-developer features. ## Full article daily.dev links to this article rather than hosting it.
