OpenAPPA is an open-source deterministic guardrail and information-flow policy engine for LLM agents. The page describes flow-based security labeling, CI validation, remedy plans, sanitizers, authorities, and subagents, with links to docs, GitHub, Discord, and benchmark claims.

A Vercel article showing how to use GPT-6 Sol with the AI SDK evaluation API to assess draft replies, score evidence-based answers, and read structured results in TypeScript.

AI code security scanner that reviews a repository, flags exploitable issues, and provides a scoped fix prompt for each finding.

An offline hybrid retrieval engine for RAG that runs on-device, including phones. The repo shows BM25 plus dense retrieval, cross-encoder reranking, sparse expansion support, and bindings for Rust, Python, Swift, and Kotlin.

An in-memory Tree-sitter AST pruning and context firewall MCP server for coding agents like Cursor and Claude. The repo includes installation steps, diagnostics, benchmarks, and a clear usage path for local setup.

A LangGraph-based workflow that generates, benchmarks, validates, and iterates CUDA kernels using a C++/CUDA harness. It targets workload-specific optimization with support for NVIDIA research lookup and optional Nsight Compute profiling.

A local gateway for Claude Code that logs tool calls, enforces approval rules, and trims noisy tool output to save tokens.

A Mac notch app that surfaces Claude Code and Codex approval prompts in the menu bar/notch so developers can approve or deny requests without switching back to the terminal.

AX is a local router for coordinating coding agents across terminals and repositories. It gives sessions names, lets agents exchange messages on the same machine, and supports Claude Code, Codex CLI, Grok Build, OpenCode, and Pi.

A VS Code extension that turns codebases into an interactive call graph and exports compact execution context for AI assistants. It also helps review staged, branch, and PR changes by showing impact and blast radius.

Open-source coordination protocol for coding agents that helps detect intent conflicts before code conflicts, built above Git and integrated with tools like Claude Code, Codex, and Cursor.

A self-hosted mobile web UI for watching terminal-based coding agents, replying to blocked prompts, and getting push alerts from a phone.

A utility for AMD GPU users running local AI on Windows or Linux. It detects the GPU, applies the right HSA_OVERRIDE_GFX_VERSION setting, offers health checks, and benchmarks Vulkan vs. HIP/ROCm for local LLM setups.

Open-source cross-platform SSH/SFTP client and server manager with live telemetry, split-pane workflows, self-hosted end-to-end encrypted sync, and MCP/AI integration.

An unlisted pastebin for HTML or Markdown files that’s built for coding agents and quick sharing. It supports one-command publishing, agent-driven workflows, and renders Markdown into readable pages.

CLI tool that monitors usage limits and automatically hands off between Claude Code, Codex, agy, and Grok in the same terminal.

Open-source control plane and proxy for managing multiple MCP servers behind one endpoint, with routing, policy, auth, logging, and rate limiting.

Local memory and skill layer for coding agents that records procedures, reinforces useful patterns over time, and keeps provenance and trust tied to each memory.

A public guide to principles for building reliable LLM applications and production-ready agents. The page lays out 12 factors, with discussion of tool calls, context windows, control flow, human handoff, and state handling.

A framework for dbt development that uses AI agents with structured specs, deterministic infrastructure controls, and numeric diffs instead of code-only review.

A Python package that adds Conduct Guard as a LiteLLM guardrail to enforce runtime policy on LLM calls. The page explains install, proxy wiring, verdict behavior, session tracking, fail modes, and configuration options.

A benchmark writeup comparing GraphQL-over-MCP and REST-over-MCP setups, showing lower token use and inference cost for GraphQL in agentic tasks.

A macOS voice assistant for Claude Code that talks through project ideas, writes specs, launches builds, and alerts you when a session needs attention.

AirmailAI is a BYOK LLM chat app with a browser-extension backend that lets users connect their own keys and chat with providers like OpenAI, Anthropic, Google, and OpenRouter. The page highlights privacy-by-design messaging, file upload, web search, and zero-markup pay-as-you-go usage.
