Find the open-source solution that fits.

GitComet is a local-first, cross-platform Git desktop client built to remain responsive when browsing large repositories and file diffs. It can run as a standalone GUI or register as Git's difftool and mergetool for interactive or headless diff and merge workflows. The README lists staging, commits, remotes, branches, worktrees, and multi-repository browsing as planned open-source edition scope. Git 2.50 or newer must be installed locally.

Give the skill a URL to run either a basic or full SEO audit and receive an HTML report organized around concrete fixes. Deterministic Python checks cover items such as HTTP behavior, robots and sitemaps, metadata, canonicals, and structured data, while the agent handles semantic judgments like keyword intent, content quality, and expected page type.

OpenSail lets teams build reusable agents, applications, and automations inside workspaces connected to systems such as Slack, email, issue trackers, repositories, internal APIs, and MCP servers. Jobs can start from schedules, buttons, webhooks, messages, or app events, with approvals, budgets, permissions, logs, and run history added as needed. Its desktop and web interfaces can run projects through local processes, Docker Compose, or Kubernetes for teams that want control over both agent behavior and deployment.

Add framework and architecture guidance for Angular, React, Next.js, TypeScript, Django, and other development work to agents such as Claude Code, Codex, Cursor, and OpenCode. The repository combines the maintainer's opinionated, battle-tested conventions with community skills accepted through voting, and manual setup places selected skills in each agent's expected directory.

MarkerOn lives in the system tray and opens a screen-wide annotation layer with a global shortcut. Draw, highlight, add arrows, shapes, or text, then enable click-through mode to keep the marks visible while interacting with the application underneath. It also includes a whiteboard, image copying, and optional drawing persistence. The roughly 1.5 MB desktop app supports Windows, macOS, and Linux.

OpenPackage is a CLI package manager for coding-agent rules, commands, subagents, skills, and MCP configuration. It tracks sources and dependencies, installs or removes selected components, and translates files into the target layout used by different AI coding platforms. It is designed for developers and teams that want to reuse the same agent setup across projects and tools instead of maintaining each configuration manually.

Use this curated directory to browse official resources and community skills for development, productivity, DevOps, data work, writing, and design across multiple coding assistants. It also provides an online search experience and several example skills. Its installer handles only the examples bundled in this repository, not every third-party project listed.

Gitagent represents an AI agent as a Git repository, with model configuration, identity, rules, memory, tools, skills, hooks, and workflows stored as reviewable files. You can fork an agent, branch its personality, diff rule changes, and inspect memory history with normal Git operations. The runtime supports OpenAI, Anthropic, and OpenAI-compatible providers, and requires Node.js, Git, and the relevant API credentials.

Gramax combines a visual Markdown editor with local file storage and Git-based collaboration. Teams can edit documentation from a desktop or browser app, connect repositories hosted on services such as GitHub, GitLab, Bitbucket, or Gitea, and publish the result as a documentation portal. The portal can be self-hosted with Docker or generated as a static site.

IconChanger lets macOS users replace application and folder icons through either a graphical interface or a scriptable command-line tool. It integrates with macOSicons.com, previews changes in the Dock, and keeps favorites and history for reuse. A background service can restore custom icons on a schedule or after application updates overwrite them. The app is available through Homebrew or as a downloadable DMG.

flutter-ai-rules packages Flutter, Dart, state-management, testing, and tool-specific guidance as Agent Skills and traditional rule files for environments such as Cursor and Windsurf. Copy or link only the skills and rules your project needs so the coding agent can load them contextually. The material is drawn from official documentation, which also means guidance from different packages may sometimes conflict.

Create general-purpose agents in TypeScript with streamed events, filesystem or shell tools, persistent multi-turn sessions, and middleware for compaction, retry, and turn tracking. The SDK also covers subagents, MCP servers, on-demand skills, virtual filesystems, and React or Vue chat integration on top of Vercel's AI SDK.

Vestige is a local-first Rust MCP server that stores agent memories on the user’s machine and searches backward for changes that may have caused a later failure. Its compact tool set covers recall, causal backfill, ingestion, suppression, graph work, and maintenance, using SQLite, full-text search, and vector indexing underneath. The first run downloads an embedding model; afterward the service can work offline on macOS, Linux, or Windows.

Auto-Commenter is a Claude Skill workflow combining language-model generation with Playwright MCP for Reddit engagement. Users provide eight to ten of their own comments to create a style guide, configure target communities and optional product context, then let the workflow analyze posts, draft comments, fill daily quotas, record activity, and flag potential leads. Reddit is the implemented platform; other networks are extension patterns rather than finished integrations. Use still depends on following community rules, rate limits, and platform policies.

This repository turns invoice-style Excel data into Neo4j nodes and relationships with pandas, then shows how to convert graph relationships into matrices. It preserves a legacy py2neo v3 and Neo4j 3.x teaching path while adding a modern example with the official driver, vector indexes, and GraphRAG-style retrieval. Current Python and Neo4j environments may require changes to the pinned legacy code.

Use this curated directory to find legal workflows by category, including AI regulation, privacy and cybersecurity, legal research, operations, and jurisdiction-specific practice. Each entry links to a skill folder that can be installed in compatible agent tools. The collection spans tasks such as compliance reviews, policy and contract analysis, case-law research, budgeting, and matter management rather than acting as a single legal application.

Inspect Evals gathers benchmarks for coding, cybersecurity, safeguards, reasoning, knowledge, and other model capabilities. Researchers can run individual tasks with Inspect AI, improve included evaluations, or register externally maintained implementations. The project recommends Python 3.11 or 3.12 for the most reliable development and execution experience.

AEON turns repository-based skill prompts into autonomous runs that can be scheduled, chained, and monitored from a dashboard. Results can be delivered through Telegram, Discord, Slack, or email, while each skill declares the API keys or MCP servers it needs. Setup requires Node.js 20+, an authenticated GitHub CLI, and your own repository copy; some skills depend on additional credentials.
