A Python MCP server that lets a parent LLM delegate work to named sub-agents defined in YAML, with per-agent prompts, model settings, and downstream MCP tool access.

Cast is an open-source, self-hosted harness for multi-user Claude agents. It focuses on routing, identity, and access control outside the prompt, with support for agent building, review flows, and extensions like email, calendar, web fetch, and WhatsApp.

A technical guide that shows how to build a small CLI-based LLM agent for microservices using tool discovery, model calls, conversation history, and a REPL loop.

Chrome MV3 extension that organizes existing AI tabs into a structured model council for cross-checking prompts across ChatGPT, Claude, Gemini, Perplexity, Merlin, and Grok.

Smriti is an open-source system for shared reasoning state across coding agents like Claude Code and Codex. It treats project reasoning like version-controlled state, with local setup, a CLI, backend, and frontend for coordinating multiple agents on the same repo.

Open-source AI SEO optimizer CLI that audits pages, generates meta tags, analyzes keyword gaps, and drafts blog outlines. It can run free for audits and uses a KianBot API key for AI-assisted features.

An agent skill for starting or extending Django projects, with ready-made scaffolding, stack choices, and safeguards for common production pieces like auth, jobs, Redis, email, and deploy setup.

A Claude plugin that adds interactive architecture diagrams to Plan Mode, letting users review, annotate, and revise system designs in real time.

VT Code is a WebMCP browser code editor with a terminal-paired agent workflow and an in-memory fallback mode. The page shows workspace setup, pairing steps, review-before-writing controls, and a client-run evidence recorder.

A desktop Hacker News client that summarizes long threads, extracts key points with quotes, and lets you chat with loaded discussions using Claude Code or Codex CLI.

A scheduled agent cockpit for running multiple Claude Code sessions in parallel, each in its own git worktree, with optional Telegram control, secret vaulting, and schedule-based guards that can avoid token spend on quiet runs.

MindShield is a browser extension that adds a reflection pause before sending simple prompts to AI tools, using local on-device classification to reduce false positives and keep prompts private.
