  1. DietrichGebert/ponytail

    Ponytail is a single skill prompt (skills/ponytail/SKILL.md, with a compact AGENTS.md) that makes coding agents write only the code a task needs, reusing existing components while keeping validation, error handling, security and accessibility. The author benchmarked it in Claude Code with Opus 5.5 over 39 tasks, 5 runs each, including a real FastAPI + React repo. They report -53% code, -41% time, -26% cost and -45% tokens, and 98% of risky logic shipping with a test versus 68% without. It adds /ponytail-review and /ponytail-audit commands, a Claude Code cost/token band with a local board, and installs through Claude Code and Codex plugin marketplaces or as a rules file for Cursor, Copilot, Gemini, OpenCode and others.

  2. Llama.cpp on a jailbroken PS5: run any GGUF model natively on the console

    PS5LM is a homebrew app for jailbroken PS5s (firmware 7.00–13.60). It runs llama.cpp with the ggml-vulkan backend on the console's RDNA 2 GPU, using 11.4 GB of shared memory, and loads any GGUF model. It serves OpenAI /v1/chat/completions, Anthropic /v1/messages (usable from Claude Code, Codex and opencode) and a browser chat page on port 8081. It also supports image-projector vision models and TypeSafe-style decision models through a /v1/systemone endpoint. A planner picks the longest context and best cache that fit the free memory, and the app downloads models from Hugging Face.

  3. mattpocock/skills — agent skills for engineers

    mattpocock/skills is a collection of small, composable "agent skills" for software engineering that install into Claude Code, Codex, GitHub Copilot, Gemini CLI, Cursor, OpenCode, Devin, Windsurf, Amp and Pi via plugin managers or the `npx skills` CLI. It packages practices like interview-driven requirement gathering (/grill-me, /grill-with-docs), domain-model/glossary building, test-driven development with red-green-refactor (/tdd), bug diagnosis loops, codebase architecture improvement, ticket triage and spec-to-implementation workflows (/to-spec, /to-tickets, /implement, /implement-spec), splitting skills into user-invoked orchestrators and model-invoked reusable disciplines. It's built by Matt Pocock as an alternative to heavier process-owning frameworks like GSD, BMAD and Spec-Kit, aiming to keep engineers in control while giving coding agents better feedback loops and shared vocabulary.

  4. overmind-core/overmind

    Overmind is an open-source platform (MIT SDK/CLI, AGPL-3.0 platform, self-hostable) that instruments an agent's code via OpenTelemetry tracing, turns the resulting production traces (or any dataset) into a fine-tuned model benchmarked against user-defined eval metrics, and serves it through one unified API with downloadable/retrainable weights. It ships an SDK, CLI, REST API, Console, and an MCP server exposing project tools and workflows (investigate-capability, finetune-capability, ship-model) for Cursor, Claude Code, OpenCode and Codex, and can sync traces from Langfuse, LangSmith, Braintrust or Galileo; self-hosting runs via Docker Compose with Postgres, Redis, Celery workers and Modal-based GPU workers for fine-tuning/serving (vLLM).

  5. claude-mem — persistent memory system for Claude Code and other coding agents

    Claude-Mem is an open-source persistent memory plugin for Claude Code and other coding agents (Codex, OpenCode, Grok Bot, T3 Code, OpenClaw) that captures tool-usage observations during sessions, compresses them into semantic summaries, and reinjects relevant context into future sessions. It uses five lifecycle hooks (SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd), a local SQLite database, a Chroma vector store for hybrid semantic+keyword search, and exposes three MCP tools (search, timeline, get_observations) that follow a token-efficient layered retrieval pattern to cut context costs roughly 10x. It is Apache-2.0 licensed, built with the Claude Agent SDK and TypeScript, and ships an optional hosted "observer" memory service alongside self-hosted options via OpenRouter/Gemini keys or an Anthropic plan.

  6. NVIDIA/OpenShell — sandboxed runtime for autonomous AI agents

    OpenShell is NVIDIA's open-source runtime for safely running fleets of autonomous AI agents: each agent runs in an isolated sandbox where kernel-level controls enforce a declared policy over file access, syscalls, and network connections, and credentials are injected only for approved endpoints rather than exposed to the agent directly. Policy changes are checked with formal verification to flag risky new access (new hosts, new API methods) before they're approved, and the project ships a CLI, gateway, Kubernetes/Helm deployment, and a tutorial running OpenCode against an OpenRouter model.

  7. OpenShell — safe, private runtime for autonomous AI agent fleets

    OpenShell is NVIDIA's open-source runtime for running fleets of autonomous AI agents inside isolated sandboxes. Declarative policies cover filesystem, syscall, process and network access. These are enforced at the kernel level, and credentials are injected only into requests bound for approved endpoints. Policy changes are checked with formal verification so risky new access waits for human review. It ships a CLI, a gateway control plane (Helm deployment on Kubernetes), SDKs, extensibility hooks (middleware, interceptors, compute drivers) and installable agent skills, and it can run agents such as OpenCode.

  8. Launch HN: Magnitude (YC S25) – Self-optimizing inference engine for agents

    Magnitude is an open source local inference engine (Apache 2.0) that compiles and tunes its GPU/CPU kernels on the user's exact device before a model runs, claiming up to 2x faster decode than llama.cpp (92% faster on Metal, 19% on CUDA) with 27% lower memory per agent. It ships as a cross-platform desktop app with a bundled CLI and an OpenAI-compatible API, offering one-click connections to agent tools like Pi, OpenCode, Hermes, Codex, OpenClaw, Claude Code, and Cline, running fully offline on Apple Silicon, NVIDIA, AMD, or CPU-only hardware.

  9. rehan-remade/universal-modder

    universal-modder is a set of Agent Skills, a CLI (um) and a shared knowledge base (field notes in knowledge/) that let AI coding agents such as Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot and OpenCode find a PC game's engine, reverse-engineer its code, build a working mod, generate art/3D/sound assets via the fal MCP server (or a local ComfyUI server), test the mod in the running game, and write a field note for the next agent. It ships worked examples — a weapon/boss pack for Terraria via tModLoader, a new civilization for Age of Empires II DE, and a real-time Minecraft-inside-GTA-V passthrough mod — each documented with a field note of exact versions, routes and gotchas, and agents can open pull requests to grow the shared knowledge base.

  10. https://github.com/dmdhrumilmistry/security-harness

    security-harness is an open-source Claude Code plugin (also packaged for Gemini CLI, Codex and opencode) that orchestrates subagents — sh-recon, sh-hunter, sh-chainer, sh-verifier, sh-reporter — through a static-analysis pipeline covering 15 vulnerability classes (IDOR/BOLA, SQLi, XSS, SSRF, injection, auth, deserialization, path traversal, secrets, CSRF, XXE, open redirect, crypto, race conditions, file upload), producing README/JSON/SARIF/HTML/PDF reports with PoCs, CVSS and CWE/OWASP mappings. It also ships sh-pr-review, a per-PR merge-gate skill that posts inline findings and a commit status scoped only to code the PR itself introduced or aggravated, with caching, dedup via fingerprints, and a scheduled GitHub Action that keeps its per-class knowledge bases fresh by having one AI agent draft updates from allowlisted sources (OWASP, PortSwigger Research, CWE/CAPEC, HackerOne) while a separate adversarial reviewer agent fails-closed against prompt injection before auto-merge.

  11. Agent Control Standard (ACS)

    Agent Control Standard (ACS) is an OWASP GenAI Security Project specification that lets a separate Guardian Agent inspect an AI agent's proposed actions before they execute and return allow/deny/modify/ask/defer over an authenticated JSON-RPC wire, with OpenTelemetry/OCSF audit trails and a CycloneDX/SPDX/SWID AgBOM inventory. The reference implementation runs Microsoft's Agent Governance Toolkit (AGT) behind the ACS contract with Bun, including host shims for Claude Code and OpenCode, and demonstrably denies a destructive `rm -rf /` command from a live coding-agent session while allowing benign ones. The project is explicit about current gaps — the wire is unauthenticated (issue #70) and the reference Guardian fails open by default (issues #32/#37) — and only 2 of 16 lifecycle hooks are evaluated live in v0.1.0.

  12. dzhng/jevgrep

    Jevgrep (the `jg` CLI) lets a coding agent ask a natural-language question about a repository and get back relevant files, reading leads, and verbatim source excerpts in one response, using an LLM (Jev) to judge relevance across folders, files, and declarations instead of relying on grep/ripgrep alone. It ships an installable "skill" for Claude Code, Codex, OpenCode and other agents that teaches them when to call jg versus their normal tools, and requires a key for Vercel AI Gateway, TypeSafe, OpenRouter, or OpenCode Zen. A reported ten-task SWE-bench repeat found ~40% lower coding-agent cost ($7.62 to $4.52) but a lower solve rate (7/10 vs 8/10 baseline), explicitly framed as a cost/quality tradeoff rather than a win.

  13. AgentSystemLabs/agent-office

    agent-office is an open-source Node.js application that renders your team's projects as floors of a cartoon 3D office, where each Claude Code, OpenCode or Codex coding-agent worker sits at a desk with a visible terminal others can join. It wires agent workers directly into GitHub: an issues board and PR board with diff review, CI status and merge actions, a task queue that auto-hires workers into isolated git worktrees, one-click PR creation, live worker status via Claude Code/Codex hooks and an OpenCode plugin, and per-worker cost/token tracking against Claude plan limits. It also supports multi-agent meeting-room collaboration patterns such as debate, lead and team, map-reduce, red and blue, and review panel, where several agent workers jointly produce a file and open a PR, plus shared voice chat and screen sharing for the human team.

  14. yetone/magpie

    magpie is a cross-platform menu bar app, TUI and CLI that lets you view and switch the model each installed AI coding agent (Claude Code, Codex, Gemini CLI, OpenCode, Cursor, Copilot CLI, Goose, Pi, etc.) is configured to use, editing each agent's config file surgically without disturbing comments or formatting. It runs a local gateway (127.0.0.1:3425) that translates between OpenAI Chat Completions, OpenAI Responses and Anthropic Messages APIs so every agent can point at one endpoint and use any provider's models, including routing groups that spread requests across multiple keys/subscriptions with configurable routing strategies (smart, order, rotate, usage). It can also reuse existing subscriptions (Claude Code, Codex/ChatGPT, Copilot, Devin, Gemini CLI) as providers for other agents without exposing or copying credentials, and supports encrypted profile backup/restore.

  15. nealbridges/VulnHunter

    VulnHunter is a maintained fork of Capital One's open-source agentic security scanner, reworked to run on any agent harness (Claude Code, Codex, Grok/OpenCode) instead of being Claude-Code-specific. The fork's distinguishing work is engineering, not security findings: portable "skill" prompt files with an explicit environment contract, an installer that fails loudly instead of guessing paths, Docker-based sandboxed exploit validation, and a benchmark harness that ran six full scans of one production Go service across five model/harness stacks, finding that result counts swung from 3 to 42 findings depending on how rigorously exploits were validated. It ships three composable skills (/vulnhunt, /vulnhunter-fix, /vulnhunt-fix-verify), a headless batch-runner (harness/), and a deterministic manifest-writing CLI (vh).

    Agentic-Bug-Hunter is an open-source CLI (bughunter) and Claude Code plugin that automates the bug bounty pipeline end-to-end: recon, vulnerability hunting across 26 web2 and 10 web3/smart-contract bug classes, a "7-Question Gate" validation step to kill weak findings, and submission-ready report generation for HackerOne, Bugcrowd, Intigriti, and Immunefi. It orchestrates existing scanners (subfinder, httpx, nuclei, katana, ffuf, dalfox) behind a multi-provider LLM layer (Ollama, Groq, DeepSeek, Claude, OpenAI) and cross-session "hunt memory," and also ships an MCP server for use from Cursor, Codex, or OpenCode.

  17. vinilana/jev-gateway

    jev-gateway is a local proxy that sits between coding agents (Codex, Claude Code, OpenCode, Kilo, Gemini CLI, Devin) and their LLM backend, intercepting only the tool-selection decision and routing it to TypeSafe's small, fast "Jev" model instead of the main reasoning model, while forwarding everything else untouched. It supports forced tool_choice, hint-based suggestions (for APIs like Anthropic's that can't force a tool mid-turn), a live dashboard for cost/latency/routing metrics, and a companion benchmark repo (jev-gateway-bench) showing routing helps most on debugging tasks but can hurt some models on feature-building tasks.

  18. coldteadotai/abide

    Abide is a CLI (npx @coldtea/abide) that hooks into Claude Code, Codex and OpenCode to check every agent edit or turn against project rules written in AGENTS.md/CLAUDE.md that a linter can't enforce (e.g. 'never let a raw error reach a user', 'no premature abstractions'). It uses Jev, TypeSafe's calibrated decision model, to answer a typed yes/no probability per rule per diff instead of a full LLM call, making it cheap (~300ms, fractions of a cent per turn) enough to check every edit; violations above a threshold are fed back to the agent to repair in the same turn.

    geo-sleuth is an open-source Agent Skill that lets any tool-using agent (Claude Code, Codex, Cursor, Gemini CLI, OpenCode, GitHub Copilot) geolocate a photo without relying on text, license plates or landmarks, instead using OpenStreetMap geometry, elevation data, satellite tiles and street view. It structures the task as a scored candidate board with ~20 single-purpose Python scripts (sun/terrain/osm/pose analysis, CLIP-ranked satellite matching, DINOv2+SIFT street-view matching) that do the ranking, while the LLM only judges among top candidates and must cite the command/file behind every claim. Output includes coordinates with an error radius, camera heading, and an evidence image.

    WordPress-Security-Skills is a GitHub repo of modular 'Agent Skills' (per the open Agent Skills spec) that install into AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Gemini CLI to guide secure-by-default WordPress plugin/theme development and security code review. Each skill targets a documented failure mode in AI-generated WordPress code — missing nonce checks, broken authorization, missing output escaping, unprepared SQL queries — with when-to-use guidance, common AI mistakes (wrong vs right), code examples, and checklists tied to official WordPress API references. It is explicitly instructional Markdown/PHP reference material, not a scanner or automatic protection, meant for developers and reviewers auditing AI-written or third-party WordPress code.

  22. sage — Agent Detection & Response (ADR) for AI coding agents

    Sage is an "Agent Detection & Response" (ADR) security layer that intercepts tool calls made by AI coding agents — shell commands, URL fetches, file writes — and screens them through multiple detection layers before execution. It combines cloud URL reputation, 300+ YAML local heuristics, a two-tier (heuristic + fine-tuned ML) prompt-injection detector for fetched content, npm/PyPI package supply-chain checks (registry existence, file reputation, age), installed-plugin scanning at session start, and Windows AMSI integration. It ships as a plugin for Claude Code, Cursor, VS Code, OpenClaw, and OpenCode, and is published by Gen Digital (also distributed under the Norton/Avast Sage branding).

    A curated GitHub list cataloguing open-source and source-available tools for orchestrating AI coding agents, organized into categories: terminal multiplexers/TUIs (tmux+worktree managers like claude-squad, amux, agent-manager), desktop/web parallel-session apps (Ghostex, Tempest, Vicoa), multi-agent swarms with inter-agent coordination (crewAI, gastown, loki-mode), autonomous loop runners (Ralph Wiggum-style loops like ralph-orchestrator, bernstein), issue/board-driven task runners (cyrus, open-swe, claude-code-action), infrastructure/control-plane primitives (Concord MCP, Agent Messaging Protocol), and always-on personal assistants (openclaw, rowboat). It covers dozens of tools working with Claude Code, Codex, Gemini CLI, OpenCode, and other agent CLIs, plus a watchlist of stalled projects. Useful as a map of the fast-moving agent-orchestration tooling landscape as of mid-2026.

  24. Nehanth/pooled

    Pooled runs one open model (Qwen 3.6 35B MoE, a 27B dense hybrid, smaller Qwen3/SmolLM) across devices in a browser "room". Each tab holds a slice of layers and runs them on its own GPU with custom WGSL kernels. Hidden states pass over WebRTC, and speculative decoding is checked against plain decoding by golden tests. It also ships a Code-mode agent loop with a sandboxed preview, and an npx CLI bridge (@pooled/cli) that exposes the room as an OpenAI Chat Completions/Responses and Anthropic Messages endpoint with grammar-constrained tool calling, so Codex CLI, Claude Code and opencode can use it. The README includes latency-injected benchmarks, a comparison with exo, Petals, llama.cpp RPC and WebLLM, and a threat model.

    Cumora is a cross-platform team-chat application where AI agents sit alongside humans as first-class participants — holding persistent personas and memory, claiming Kanban work, coordinating with each other, and sending real email — rather than only responding when addressed. Agents can run on Cumora's cloud (per-agent Kubernetes pods driving a multi-hop tool-calling loop over the OpenAI Responses API) or in "Bring Your Own Agent" mode, pairing a local Mac/VPS daemon with an existing coding-agent backend (Claude Code, Codex, Cursor Agent, Gemini CLI, OpenCode, Qwen Code, Google Antigravity, etc.) while keeping provider keys off the server. The repo documents a concrete coordination design — a seen-cursor freshness gate that holds stale replies, atomic claims on units of work, a small-brain triage gate, and a transactional Postgres outbox for realtime fan-out — making it a useful reference for building multi-agent systems that avoid agents colliding on shared work.
