Lex

Gives AI agents repo-local memory and architectural guardrails. Frames capture work snapshots with reference points, blockers, next actions, and touched modules. Recall pulls relevant prior context on demand, optionally enriched with Atlas neighborhood maps showing module dependencies and permissions. Policy files define architectural boundaries as code, enforced via CLI checks in CI. The MCP surface exposes remember, recall, check, and instruction generation as tool calls. Stores everything in SQLite and repository files, not cloud services. Useful when your agent keeps asking you to repeat project constraints, architecture decisions, or context from interrupted work sessions.
