Managed Deep Agents v0.9
Managed Deep Agents v0.9 from LangChain adds three things for internal agents that work like teammates. Agents can now create their own reminders and recurring tasks mid-conversation, running with the requester's permissions and posting back to the same channel. One deployment can pick its model, skills, tools and sandbox on every run. And agents can react to Slack messages right away. Public beta. wire:producthunt

MELRA
When an AI agent writes to a file or calls an API, a timeout can leave it unclear whether the change happened. MELRA checks tool calls against local policy, pauses sensitive actions for approval, verifies the declared result, and keeps a redacted receipt. If a write's outcome is unknown, MELRA holds it for reconciliation instead of retrying blindly. Open-source alpha; requires Node.js 22.13+ or 23.4+. wire:producthunt

Quorus
Put Claude Code, Codex, Gemini CLI and opencode in one room. They wake on @mention, work in their own git worktrees, review each other's commits and push to your repo. quorus scorecard shows whose code holds up in your repo. Try it with no keys: pipx install quorus-ai && quorus demo. Open source, MIT. wire:producthunt

Figma Specs
Figma Specs is a collaborative Markdown document that can live on its own or beside your designs. Embed Figma frames and FigJam diagrams, work through comments with teammates and agents, and pass the full context to coding agents through MCP. wire:producthunt

buddylist
A free desktop app for macOS (Apple Silicon), Windows and Linux that puts Claude Code, Codex, Gemini and OpenCode in an MSN-style buddy list. Use separate Git worktrees for separate jobs, or group-chat agents in a shared folder. Let them take turns, answer together or hand unfinished tasks to another agent. Review diffs, run terminals, preview your app and track PR checks beside the chat. Bring your own agent accounts; provider access and usage are separate. wire:producthunt

Framefields
Framefields is a high-performance, code-first video engine powered by native WebGPU in Node.js. Built for AI agents and engineers, it replaces bulky creative suites with a single npm package: motion graphics, Photoshop-grade VFX, 3D scenes, and audio DSP. Zero Chromium or browser overhead—render deterministic, frame-accurate video and export hardware-accelerated MP4s directly from TypeScript. wire:producthunt

ai-usage
A small open-source tool that shows what's left of your Claude Code, Codex and Grok limits on every machine you run, and whether it will last until the reset. No account, no config. Mac menu bar app included. wire:producthunt

claude-term
A macOS terminal built for Claude Code. Track tokens per session (input, output, cache), see which skills eat your context, and watch your 5-hour and weekly limits live. Every session in one sidebar. Local, no telemetry, open source. wire:producthunt

InfinityDB
InfinityDB is an open-source neurosymbolic memory engine for AI agents that runs locally on SQLite WAL mode. Unlike vector memory that relies on costly LLM extraction, InfinityDB provides sub-5ms hybrid recall, deterministic $0 fact extraction, dynamic persona conflict resolution, and SHA-256 audit proofs. Cuts agent prompt token overhead by 81.4%. Compatible with Python (PyPI), Node.js (NPM), LangChain, CrewAI, and Model Context Protocol (MCP) for Claude Desktop and Cursor. wire:producthunt
