CORE9: Local Memory for Coding Agents

core9.dev Visit website

Editorial interest 77/100 Selection signal · not a rating of the site

A local SQLite memory tool that gives coding agents project rules, decisions, and recalled notes using exact-token search.

Landing page captured for the 2026-10-20 issue.

For: Developers using AI coding agents on software projects
Worth noticing: The homepage separates durable project rules from mistake patterns, append-only decisions, and archival notes retrieved on demand.

Field notes

The memory model distinguishes material that should persist from material that can be fetched when relevant: the page lists 22 invariants, six mistake reflexes, six append-only ADRs, and an archival graph. It says the invariant, reflex, and ADR tiers use roughly 180, 90, and 120 tokens per prompt respectively; these are the site's own figures, not independently verified measurements.
