inwo. agency-agents is an open-source collection of 218 specialized subagent 'personalities' you can install into Claude Code and a dozen other tools. What it is, how to install and use it, how it compares to writing your own, and the honest caveats.
find-skills turns 'I wish my agent could do X' into 'find and install a skill for X' — automatically. How it works with the skills CLI and the skills.sh registry, how to use it, and the trust caveats of letting an agent install its own capabilities.
Ponytail is a one-file 'lazy senior dev' skill that makes coding agents stop and pick the simplest solution that works — cutting code by ~54% (and tokens ~22%) on a real agentic benchmark. What it is, how the ladder works, what trusted reviewers found, and the honest caveats.
What agent skills are, how Claude Code loads them (and what they cost in context), the real risks, and a lean, honest stack for code review, security, quality and multi-agent work — with install/remove/update for each.
A community-built, Apache-2.0 library of 754 structured cybersecurity skills that give an AI agent senior-analyst playbooks — mapped to MITRE ATT&CK, NIST CSF 2.0, ATLAS, D3FEND and NIST AI RMF. What it is, how the skills are built, defensive use cases, how it compares, and the honest tradeoffs (including its dual-use responsibility).
Addy Osmani's Agent Skills packs the workflows, quality gates, and Google engineering practices that senior engineers use into markdown skills an AI coding agent follows across the whole development lifecycle. What it is, how it works, and the honest tradeoffs.
mattpocock/skills is Matt Pocock's everyday .claude skills folder, published — small, composable agent skills that fix the common failure modes of coding agents (misalignment, verbosity, broken code, ball-of-mud architecture) without taking over your process. What it is, how it works, the standout grilling and TDD skills, and the honest tradeoffs.
UI UX Pro Max is an open-source AI skill that gives a coding agent a design brain — a reasoning engine that turns a one-line prompt into a complete design system with styles, palettes, typography, and anti-patterns. What it is, how it works, what it produces, and the honest tradeoffs.
awesome-claude-code is a selectively curated 'awesome list' of skills, agents, hooks, slash commands, status lines, CLAUDE.md files and tooling for Claude Code. What it is, how it's organized and curated, the standout categories, how it compares to bigger aggregators, and the honest tradeoffs.
A Claude Code skill that makes the agent talk like a caveman — cutting output tokens by up to ~75% while keeping full technical accuracy. Why, how it works, how to install it, and real before/after numbers.
Superpowers is an open-source plugin that gives a coding agent a full development methodology — brainstorm, plan, then build with TDD and subagent review. What it is, how it works (and why it stays token-light), real opinions, use cases, and its pros and cons.
