    Skills for Real Engineers

    agent-skills

    Matt Pocock's composable agent skills for real engineering work, usable with any model or harness.

    The repo added 2,207 stars in the last day and holds the top spot on GitHub's daily trending page, at 255,080 stars overall with 21,501 forks. The skills are deliberately small and composable, pitched against process-heavy approaches like GSD, BMAD and Spec-Kit that take control away from the engineer. The latest tagged release, v1.2.3 from 6 August, made the diagnosing-bugs skill redact secrets before showing commands and captured output. The repo was last pushed on 4 September.

  • 02

    Ponytail

    agent-skill

    Skill that makes coding agents write less code, measured against a bare agent on real sessions.

    Ponytail gained 12,186 stars this week and 1,539 in the last day, sitting at 129,813 stars less than three months after its creation in June. Its README reports roughly 54 percent less code on average across 12 feature tasks, up to 94 percent where an agent over-builds, with every safety guard kept. The v4.9.0 release on 7 August bundled five weeks of work: a persistent default mode, Qoder support, subagent scoping and about 30 fixes across Windows, Codex and OpenCode. It is written in JavaScript and was last pushed on 4 September.

  • 03

    ECC

    agent-harness

    Harness optimisation layer adding skills, instincts, memory and security to Claude Code, Codex and Cursor.

    ECC added 6,394 stars this week and 1,485 in the last day, reaching 251,789 stars with 37,831 forks. Version 2.2.0 shipped on 28 August with one guided installer for Claude Code, Codex and Kimi, native Antigravity 2.0 support and an opt-in Nasiko CLI lifecycle bridge. The release pipeline now requires the exact npm archive to pass lifecycle tests on Linux, macOS and Windows before the latest tag moves. The README carries an official-sources-only warning because of unofficial mirrors, which says something about its reach. Last push was 7 September.

  • 04

    OpenCode

    coding-agent

    Open-source terminal coding agent with a large provider list and package-manager installs on every OS.

    OpenCode added 551 stars in the last day and tops GitHub's daily TypeScript trending, at 205,396 stars and 26,785 forks. Release v1.18.29 on 4 September fixed Codex OAuth model filtering so integer GPT versions like GPT-6 Astra show up for OpenAI subscription users. The project ships almost daily, with a console change published on 7 September, and installs via curl, npm, Homebrew, Scoop or Chocolatey. The README is translated into more than twenty languages, and the 5,706 open issues reflect a very large user base rather than neglect.

  • 05

    Hermes Agent

    agent-framework

    Nous Research's self-improving agent that builds skills from experience and keeps memory across sessions.

    Hermes Agent added 520 stars in the last day and leads GitHub's daily Python trending at 242,682 stars with 49,914 forks. The v0.21.0 release on 31 August, called the Pantheon release, ships Bot Mode into the desktop app so named agents with their own group chats can work together. The release notes count roughly 5,800 commits, 2,475 merged PRs and 2,100 closed issues from more than 760 contributors since v0.20.0. It runs on a cheap VPS or a GPU cluster and accepts any model provider. Last push was 7 September.

  • 06

    Prime Agent

    agent-harness

    Prime Intellect's open coding and research agent built on Recursive Language Models and a continual harness.

    Prime Agent has gained 17,024 stars this month and sits at 20,074 stars four months after creation. It treats context as variables inside a persistent REPL and calls subagents like functions, and stores memories, prompts and subagent specs as durable state the agent refines over time. Release v0.9.3 on 6 September fixed ChatGPT OAuth model discovery hiding GPT-6 Astra. Written in TypeScript, MIT licensed, with only 75 open issues and a push on 7 September.

  • 07

    OpenClaw

    agent-runtime

    Personal and team AI assistant gateway that runs on your devices and answers in your chat channels.

    OpenClaw is the largest repo on this list at 389,070 stars and 81,762 forks, and still added 141 stars in the last day on TypeScript trending. The 2026.9.2 release on 5 September focused on responsiveness: chat, dashboards and sessions stay usable while long transcripts and disk usage are processed. Upgrades now keep active settings, enabled skills and default-agent ownership intact. The architecture is a trusted gateway with untrusted execution and deterministic policy, deployable for one laptop or a shared team. Last push was 7 September.

    Google's MCP server giving coding agents control of a live Chrome with DevTools inspection and profiling.

    Chrome DevTools MCP added 965 stars this week and sits at 51,210 stars with only 101 open issues. It lets Antigravity, Claude, Cursor or Copilot drive a real Chrome, inspect the DOM, read console messages and capture performance traces, with a CLI for use without MCP. Version 1.8.0 on 25 August added parameters to heap snapshot edges and optional stack traces on console messages. The repo is Apache-2.0 licensed and was pushed on 7 September.

  • 13

    SkillSpector

    agent-security

    NVIDIA's scanner for prompt injection, exfiltration and supply-chain risk in agent skills before install.

    SkillSpector added 1,104 stars this week on Python trending and is at 16,440 stars. The README cites research that 26.1 percent of agent skills contain vulnerabilities and 5.2 percent show likely malicious intent, which is the problem it targets for Claude Code, Codex and MCP skills. Version 2.11.0 on 28 August extended supply-chain checks to installed npm dependency versions and bundled lifecycle hooks, and removed two false positives. It is part of the NVIDIA Verified Skills pipeline. Last push was 6 September.

It downloads, tunes and serves local models and works with Pi, OpenCode, Hermes, OpenClaw, Codex, Claude Code, Oh My Pi and Cline, or its own built-in harness. The CLI 0.0.11 release on 2 September added more robust service health checks and clearer errors when context length is exceeded. Apache-2.0, TypeScript, 20 open issues, last pushed on 6 September.

  • 15

    Weave Router

    model-router

    Drop-in proxy that routes each request to the right Anthropic, OpenAI or Gemini model in under 50ms.

    Weave's router added 983 stars this week on Go trending and is at 4,038 stars. It uses a small on-box embedder and a cluster scorer derived from the Avengers-Pro paper to pick a model per request, claiming 40 to 70 percent cost cuts from an endpoint change. Point Claude Code, Codex, Cursor or your own app at localhost:8080. The latest tag is router-v0.2.15 and the last commit on 6 September added more OpenTelemetry spans.

  • 16

    Context Mode

    context-management

    MCP server that sandboxes tool output and persists session memory to stop context window bloat.

    Context Mode added 85 stars in the last day and is at 20,503 stars with 1,511 forks. Its pitch is concrete: a Playwright snapshot costs 56 KB, twenty GitHub issues 59 KB, and after 30 minutes 40 percent of context is gone. It keeps raw tool output out of the window, claiming a 98 percent reduction, and enforces routing across 17 platforms via MCP and hooks. Release v1.0.169 aligned local savings reporting with its Insight platform. Last push was 6 September.

  • 17

    Apache Maka

    agent-harness

    Apache-incubating agent workspace that publishes benchmark runs and keeps an append-only log of everything.

    Maka has gained 3,647 stars this month and is at 4,848 stars three months after creation. It is measured rather than marketed: every harness comparison runs the same model with the official verifier and ships per-task results in the repo. Every model message, tool call and permission decision is an append-only ledger, so the log is the runtime. Development builds land daily, with a checkpoint fix pushed on 7 September. Apache-2.0, TypeScript.

  • 18

    Browser Use

    browser-agent

    Python library that lets an agent open pages, click, type and fill forms like a person would.

    Browser Use added 231 stars in the last day and is at 112,809 stars with 12,432 forks. Release 0.13.10 on 4 September upgraded the browser harness, pinned every runtime and build dependency exactly, migrated to MCP Python SDK 2.1.1 and cleared three pypdf advisories. Unknown MCP tool calls are now reported as errors instead of successes. MIT licensed with 393 open issues, last pushed on 5 September.

  • 19

    ai-memory

    agent-memory

    Long-term memory that follows you across twenty-plus coding agents and lets you hand off mid-task.

    ai-memory has gained 4,490 stars this month and is at 5,913 stars with only 6 open issues. The use case is quitting Claude Code mid-task and continuing in Codex in the same directory without re-explaining the architecture or failed approaches. Version 2.1.0 on 6 September added ordered LLM provider fallback chains that advance on 429s, 5xx and timeouts while preserving the original request. Written in Rust, MIT licensed, pushed on 6 September.
