Persistent cross-session memory for Claude Code — auto-capture, compress, and recall

Entry

claude-mem is a Claude Code plugin that hooks into the agent's full session lifecycle — capturing every tool call, observation, and interaction — compresses them semantically using Claude's agent-sdk, and stores everything in a local SQLite + Chroma vector database. On each new session, it injects only the most contextually relevant history via a 3-layer token-efficient retrieval system. The result: a coding agent that actually remembers your project across disconnected sessions. It's crossed 55K GitHub stars with support for Cursor, Gemini CLI, Windsurf, and OpenClaw. A community audit flagged the unauthenticated HTTP API on port 37777 as a HIGH severity issue — any local process can read every stored observation including API keys. The fix hasn't shipped yet. The 'Endless Mode' beta enables truly continuous sessions with automatic context compression when approaching token limits, making it useful for long-running projects that currently require frequent re-orientation.

Entry

Cursor 3 is a major version release that transforms the AI coding editor into a full agent coordination platform. The headline feature is a unified workspace: every agent session — whether triggered from mobile, web, Slack, GitHub, Linear, or locally — appears in a single sidebar. You can see all running agents, their current state, and switch between local and cloud execution seamlessly. The release also introduces a marketplace for agent plugins and MCP (Model Context Protocol) servers, enabling a third-party ecosystem of specialized tools that agents can discover and use. The PR and diff interface has been completely redesigned for multi-agent workflows, with visual conflict resolution when multiple agents modify related code. Cursor has been on a remarkable trajectory — from a VS Code fork to the dominant AI IDE to now positioning as an agent orchestration layer. Cursor 3 is the clearest statement yet that the endgame isn't a better text editor; it's a platform where humans and AI agents collaborate on software production at scale.

This is one of those tools that should have existed from day one of Claude Code. The fact that agents forget everything between sessions is genuinely painful for long-running projects. The 3-layer token retrieval is clever — it filters before fetching. One-command install, multi-IDE support, local-first. The AGPL license is the main friction for commercial teams.

The unified agent session sidebar alone justifies the upgrade. I had three parallel agents running — one on tests, one on docs, one on a new feature — all visible and manageable from one interface. The MCP marketplace is early but the architecture is right. Ship.

55K stars and a known unauthenticated API on port 37777 — that's not a footnote, that's a fire. Any process on your machine can read every stored observation and view cleartext API keys. The fix isn't complicated, but it hasn't shipped. Until the port is locked down, this is a hard skip for anyone working on anything sensitive.

Cursor keeps adding layers of complexity that raise the subscription ceiling without meaningfully improving the core coding experience for most developers. The $200/mo Ultra tier is real money, and the marketplace creates a fragmented dependency tree. This is a power-user upgrade, not a universal one.

The real unlock here isn't memory for Claude Code specifically — it's the emerging pattern of agent memory as infrastructure. claude-mem is one of the first tools to implement this at the session-lifecycle level rather than bolting it on as an afterthought. The vector + FTS hybrid approach and 'Endless Mode' beta point at what production agent memory systems will look like in 18 months.

Cursor 3 is building the operating system for software development. When every trigger source — Slack message, GitHub issue, Linear ticket — can spin up a coordinated agent team and you manage them from one place, we've crossed into a new paradigm for how software gets made.

If you run Claude Code for anything longer than a single afternoon, you know the pain of re-explaining your project on every session start. claude-mem just fixes that. The privacy tags are a nice touch — wrap sensitive info and it won't get stored. The web viewer is genuinely useful for auditing what the agent has learned. Solo devs, this is a clear win despite the security caveat.

Managing agent sessions from mobile is genuinely useful — I can kick off a design system refactor before bed and review the diff in the morning. The redesigned PR interface makes agent-generated code much easier to review visually. Strong upgrade.
