lm-evaluation-harness

EleutherAI's unified framework for evaluating language models on hundreds of academic benchmarks.

browserbase-bb

Use when an agent must operate the live web (navigate, act, and extract on real pages) via a cloud browser driven by act/extract/observe primitives, with a local-Chromium escape hatch using the same code.

browser-use-webui

Gradio web UI on top of the browser-use framework. It lets users run AI browser agents interactively, configure LLM providers, watch live recordings, and replay task sessions without writing Python.

cua-computer-use-agent

trycua/cua open-source computer-use agent framework: Apple Silicon-native, runs lightweight macOS/Linux VMs with sub-second cold starts; provides a unified Python interface for screen capture, click, and type actions.

deepeval

Open-source LLM evaluation framework with 14+ metrics (hallucination, faithfulness, answer relevancy) and CI support.

ragas

Reference-free evaluation of retrieval-augmented generation pipelines; measures faithfulness, answer relevance, and context precision.

hardikpandya-stop-slop

A skill file for removing AI tells from prose

mcp-tunnels-cloudflared

Use to let a hosted agent reach a private-data MCP server behind your firewall (an outbound tunnel plus a proxy, with per-server OAuth) so internal tools are usable without exposing them to the public internet.

nanobrowser

Open-source Chrome extension that runs a multi-agent browser automation system locally. Planner, Navigator, and Validator agents collaborate inside the browser with no external API calls for web tasks.

nidhinjs-prompt-master

A Claude skill that writes the accurate prompts for any AI tool. Zero tokens or credits wasted. Full context and memory retention

browserless

Browserless.io headless browser service. It provides a Docker-deployable or cloud-hosted Chrome endpoint with REST and WebSocket APIs for screenshot, PDF, scraping, and Puppeteer/Playwright remote sessions.

bytebot

Bytebot open-source computer-use agent: a Docker-based Ubuntu desktop with AI-controlled mouse and keyboard; exposes an HTTP API for agents to send click, type, screenshot, and macro commands.

phoenix

Arize Phoenix: open-source LLM observability with built-in evals, span tracing, and dataset curation for RAG and agents.

fullstack-dev-skills

A Claude Code plugin with 65 skills for full-stack development across many frameworks, 9 workflow commands for Jira and Confluence, and a /common-ground command that lists Claude's assumptions about your project.

agricidaniel-claude-ads

Claude-first paid-media operations skill for Claude Code across 12 ad platforms (Google, Meta, YouTube, LinkedIn, TikTok, Microsoft, Apple, Amazon, Reddit, Pinterest, Snapchat, X): source-grounded audits, deterministic scoring, versioned JSON reports, and capability-gated account changes.

steel-browser

Open-source browser API optimised for AI agents. It provides session management, stealth settings, proxy rotation, and a REST/WebSocket interface on top of Chromium for cloud-scale agent browser access.

swe-bench

SWE-bench: benchmark for evaluating LLMs on real-world GitHub issue resolution across 12 popular Python repositories.

microsandbox

Use as the OSS self-hosted sandbox when you need to run agent code on your own infra: libkrun-based microVM isolation with no per-sandbox vendor cost, the escape hatch from a managed runtime at high volume.

trail-of-bits-security-skills

A very professional collection of over a dozen security-focused skills for code auditing and vulnerability detection. Includes skills for static analysis with CodeQL and Semgrep, variant analysis across codebases, fix verification, and differential code review.

giskard

Open-source LLM testing framework for detecting vulnerabilities (prompt injection, hallucinations, bias) via automated scan.

codebase-to-course

A Claude Code skill that turns any codebase into an interactive single-page HTML course for non-technical readers.

agenta

Open-source LLM developer platform with prompt playground, evaluation pipelines, and A/B testing for iterating on LLM apps.

openai-simple-evals

OpenAI's lightweight benchmark suite (MMLU, HumanEval, MATH, GPQA, MGSM) for fast model capability comparisons.

claude-managed-agents-selfhost

Use for enterprise hosted-control agents (the agent loop runs at the provider while execution happens on your own infrastructure) when you want a managed control plane but data and code must stay on your machines.
