Giving coding agents persistent memory for architectural decisions with Hindsight
chitthraa · reddit · 2026-11-10
A Redditor explores why coding agents lose the reasoning behind past architectural decisions (why a tech was chosen, what constraints were set) and proposes Hindsight as a persistent memory layer:
- Ingest Git history to capture repository context
- Persist memory across coding sessions
- Retrieve past decisions and their rationale
- Inject context into future agent sessions
- Guard against outdated decisions being treated as current instructions
The goal: agents that understand not just what the code does, but why. The author invites others to share their long-term memory approaches.
