Locus gives Codex and Claude Code a local memory layer for project structure, durable decisions, searchable history, summary-first memory_recall, and diagnostics. Built on MCP. Safe-by-default. Designed so your agent stops starting from zero.

Locus is intentionally not a full agent runtime or cloud memory platform. It is a smaller local MCP memory layer for coding agents, with Codex as the first-class product path.
Locus is already a real product line for Codex, not a future promise. The current release focuses on Track C richer recall, diagnostics, and one-command install.
Track C validates redacted Codex recall through `memory_recall`: dated Russian questions, capture decisions, rejected alternatives, user style, npm errors, next steps, and validation facts pass through import, durable memory, and recall.
`redacted` is the recommended rich recall mode for Codex. `metadata` remains diagnostics-first. `full` is maximum recall and requires an explicit privacy warning; never treat it as risk-free.
`memory_status` and `memory_doctor` expose Codex-specific state so users can see what is imported, what is missing, and where the failure actually lives. `candidateGroups` make ambiguous recall inspectable instead of magical.
Track B packages Locus as `locus-memory`, adds installer, doctor, uninstall commands, and generates a marketplace bundle while keeping manual MCP fallback supported.
Most coding agents are strong inside a session and weak across sessions. Locus exists to bridge that gap without turning your workflow into a ritual of manual summaries.
Scan the codebase, map files and exports, and keep that structure searchable through MCP.
Save architectural choices and trade-offs so the next session starts with context, not guesswork.
Carbon Copy-style event ingest captures what happened, then makes it searchable through the same memory layer.
Diagnostics, audit visibility, and explicit capture modes matter as much as recall itself.
This landing page is intentionally simple. The real source of truth remains the repository: Quick Start, Codex setup, roadmap, releases, and implementation details all live there.
