Recently updated open-source projects

Give a small business one self-hosted, installable home for its internal web tools, with authentication, app management, and shared PDF, email, and per-user storage services. The Claude Code skill can scaffold, package, and upload child PWAs; the claude.ai version can only generate files and instructions. Each deployment is single-tenant, runs with Docker, and needs wildcard DNS for per-app origin isolation.

product-growth-skills first diagnoses where a product should focus by building a driver tree and ranking leverage, influence, and compounding. Its experiment-design plugin then proposes candidates, scores them with ICE, and shapes a top-three portfolio with hypotheses, metrics, guardrails, sample or duration guidance, and right-sized statistics; it does not run experiments or analyze their results.

codex-oi lets a coding agent request an independent review without leaving the terminal. It can audit a file or project, challenge a plan, inspect the current diff before shipping, or review a landed commit, using Codex by default with Gemini available as a plugin engine. It adds project context, enforces filesystem boundaries, and formats findings, while keeping every result advisory and never applying changes automatically.

Tony Skill packages a thinking-bridge method for teaching Chinese, an augmentation-focused AI methodology, and cross-temporal mental models into reusable Agent Skill material. It supports language teaching, system design, writing, and decisions through references, heuristics, and voice rules. Its present-day fact policy calls for checking current claims separately, and the framework openly notes that it lacks built-in stopping criteria.

gravador-reuniao-claude watches the Mac camera state, records system audio and microphone input on separate channels during video calls, then transcribes them locally with Whisper and offers to open Claude Code for follow-up. It can start at login, expose status and logs, and discard short false starts. macOS 14.4+, Homebrew, and system-audio permission are required; audio stays offline.

When a request involves a flowchart, architecture view, sequence diagram, state machine, ER model, class diagram, timeline, or similar structure, this skill steers Claude toward a Mermaid fenced block. It includes guidance for choosing the right diagram type and examples for each supported form. ASCII box drawings are disallowed for diagrams, while simple filesystem tree output remains an explicit exception.

Use this skill to draft or review labels, errors, empty states, onboarding, settings, and AI feature copy, with several options and concise tradeoffs. Its guidance is grounded in established US design systems and checks accessibility, inclusive language, and localization risks. It is intended for product interfaces, not blogs, ads, landing pages, or email campaigns.

Use distil-research to turn a folder of Perplexity, ChatGPT, xAI, or other research exports into a lean playbook for action. It filters sections, deduplicates overlapping ideas, routes source files to canonical, archived, or quarantine folders, and records decisions in a manifest. Incremental runs add only genuinely new signal; housekeeping mode proposes cross-topic cleanup without moving files automatically.

Install repaint with `npx skills` and ask a compatible coding agent to build or redesign an interface. Its workflow researches real references, commits a concrete token system before markup, then renders the result and iterates through visual-slop, interaction, accessibility, and public-page SEO audits. The package is self-contained, with a curated reference library and 23 evaluations, and does not depend on other skills or agents.

Guardian helps AI-assisted developers investigate production failures by correlating stack traces, logs, Sentry issues, latency signals, and distributed traces into a timeline and likely root cause. It supports common language stacks plus Kubernetes, PostgreSQL, OpenTelemetry, and Datadog workflows, and explicitly names missing evidence when a conclusion cannot be verified.

searching-apple-notes lets Claude query and update an Apple Notes archive through natural language in Chinese or English. BGE-M3 embeddings and ChromaDB run locally on the Mac, with citations in answers and formatted notes written back; no API key, MCP setup, or third-party server is required, aside from downloading the model once.

Soundings structures personal decisions that cannot be solved by looking up more facts, such as career direction, founder fit, or family priorities. You state the question, select two or three advisors, receive independent views and one question from each, then get a synthesis of conflicts and the underlying values fork. The session ends with one user-chosen next step, not a recommendation.

This agent skill organizes Solidity security reviews into repeatable modes for full audits, re-audits, integrations, quick scans, and contests. It brings together vulnerability taxonomies, protocol checklists, tool workflows, proof-of-concept templates, and severity guidance. Its output is advisory and does not replace a professional audit.

SSH-Studio gives Linux and GNOME users a visual editor for `~/.ssh/config`, with host search, common connection fields, and inline checks for duplicates or invalid ports. It also offers raw and diff views, connection testing, command copying, key generation or import, backups, and atomic saves. When installed through Flatpak, testing an SSH connection may require an additional sandbox permission override.

ux-writing-kr creates and critiques Korean UI microcopy for buttons, errors, empty states, onboarding, toasts, paywalls, dialogs, placeholders, and tooltips. It can return several variants with a recommendation and explain issues such as translationese, inconsistent honorifics, awkward length, or ambiguity. The skill emphasizes natural Korean service language and reassuring copy for moments that make users uncertain.

Pubcraft researches live search results and primary sources before drafting, then applies the structural rules of the requested surface, from SEO articles and LinkedIn to Reddit, YouTube, newsletters, and Product Hunt. It keeps working links for numerical claims, checks for AI-sounding language, and surfaces compliance placeholders for medical, financial, legal, and other regulated topics. It drafts the material but does not publish it or replace expert compliance review.

Library OS combines a Next.js template, TypeScript schema, Claude Code commands, and a book-distillation subagent to turn titles, notes, Kindle highlights, or voice memos into structured book pages. Its workflow covers capture, extraction, enrichment, and publishing, with JSON-LD, quote sharing, and dynamic social images; the full site targets Next.js 14, Tailwind, and TypeScript.

Velk helps C++ applications define components through interfaces with typed properties, events, functions, and metadata. Runtime implementations live in a shared library while consumers depend on stable public contracts, allowing internals to evolve without rebuilding every client. Its registries, plugin loading, object factory, and dense storage suit modular systems that need runtime extension and introspection.
