The Best Awesome Claude Skills Alternative for Verified Agent Skills in 2026

ComposioHQ's awesome-claude-skills is the most popular community-curated collection of Claude agent skills, listing 1,000+ production-ready skills and plugins organized by category: document processing (docx, pdf, pptx, xlsx), development and code tools, data and analysis, business and marketing, communication, creative and media, productivity, security, and app automation. It covers not just Claude Code and Claude.ai but also Codex, Cursor, Gemini CLI, Antigravity and Windsurf. The repo doubles as a showcase for Composio's MCP Gateway, which provides a single MCP endpoint for 1,000+ app integrations with built-in auth and team access controls. Skills are plain SKILL.md instruction packages that load progressively — roughly 100 tokens of metadata per skill at session start — so an agent can host hundreds without context bloat. It is a raw, free GitHub list: broad, current, and practical, but with no security scanning, version pinning, or evidence that any listed skill actually improves agent output.

SkillzBench is AIQ Labs' free, independent directory of AI agent skills, plus a free MCP tool that connects any agent to the skills you choose. It is being built to solve the exact problem Awesome Claude Skills leaves open: with skills everywhere, nobody can tell which ones actually help and which are risky — published research found roughly 26% of skills carry at least one vulnerability. SkillzBench's pipeline covers five pillars: Discover (continuously crawl and dedupe skills from GitHub), Verify (pin every version to a commit SHA, validate, license-check, security-scan, quality-judge), Benchmark (test every skill in a sandbox with the same model, with and without the skill, publishing the Lift in percentage points), Equip (one free MCP server plus per-agent loadouts, where users toggle skills and tools per agent and the agent only sees what was chosen), and Stay current (track upstream changes, re-scan, re-benchmark, notify). A 0-100 trust score is built from security, quality, license, maintenance and community signals; Lift is always shown separately from ratings and money never touches scores. SkillzBench is pre-launch — the waitlist is live and the platform is actively being built, so benchmarking, scanning and the MCP connector describe what it will offer at launch.

pricing 0

• + Purpose-built verification layer: security scanning, license checks and commit-SHA pinning directly address the ~26% vulnerability rate found in published research
• + Measured value, not vibes: sandbox benchmarks with and without each skill, with Lift always shown separately from ratings
• + Everything is free — directory, MCP connector, benchmarks and alerts; revenue comes from blog advertising that never influences scores
• + Per-agent loadouts mean each agent only sees the skills and tools chosen for it, reducing context bloat and risk
• + Continuous monitoring: upstream changes are tracked, re-scanned and re-benchmarked with notifications

• − Pre-launch: the waitlist/newsletter is live but the platform itself is not yet public, so you cannot use it today
• − No published benchmark results or live skill counts yet, since the product is still being built
• − New and unproven compared to established repos with large communities

Anthropic's official skills repository is the reference collection: docx, xlsx, pptx and pdf skills that create, read and edit Word, Excel, PowerPoint and PDF files with real formulas, real slides and filled forms, plus skill-creator (builds and tests new skills against a baseline with evals), frontend-design, mcp-builder, webapp-testing, internal-comms, doc-coauthoring, theme-factory and creative skills. With roughly 181k GitHub stars, it is among the most-used collections. Being first-party, these skills are designed to work cleanly with Claude Code's architecture and are tested against current model behaviour — the quality bar is higher than community repos, though the collection is smaller. Install via the plugin marketplace or enable directly in Claude.ai's Skills settings. Note the licensing: most skills are Apache 2.0, but the four document skills are source-available under a proprietary licence — you can use them with Claude but cannot fork them into your own product.

pricing 0

• + Official Anthropic collection — the safest default, recommended by multiple skill guides over community repos
• + Document skills are described as 'the single most useful set' for anyone producing documents
• + Clean plugin marketplace install; already available in Claude.ai settings
• + skill-creator includes evals so you can test your own skills against a baseline

• − Smaller collection than community repos like ComposioHQ's
• − The four document skills are source-available under a proprietary licence — no forking into your own product
• − Coding-methodology coverage is thinner than dedicated collections like superpowers

Superpowers is the most widely used skill collection for developers, with roughly 298k GitHub stars. Rather than a grab-bag of helpers, it is an opinionated engineering methodology: brainstorming, writing plans, executing plans, test-driven development, systematic debugging, sub-agent-driven development and working with git worktrees. Skill guides recommend adopting it as a team so every developer's agent works the same way — plans before code, tests before claiming done — and warn against installing two competing methodology collections, since two sets of rules about when to plan and when to test give the model conflicting orders. It installs through the official Claude plugin marketplace. It is more a system than a skill list, which is exactly its value for teams that code with Claude Code daily.

pricing 0

• + Most widely used developer collection (~298k stars)
• + Coherent methodology rather than random helpers — changes how the agent approaches problems
• + Actively maintained with an official plugin marketplace install
• + Free and open source

• − Developer-focused; little for marketing, documents or business operations
• − Opinionated — guides warn not to mix it with other methodology collections
• − No security scanning or benchmarks of its own

Agensi is a curated marketplace for Claude Code skills where the top picks are all free and install with a single click into ~/.claude/skills/. Its most-installed skills include code-reviewer (764 installs), git-commit-writer (232), humanize-writing (192), readme-generator, pr-description-writer, prompt-engineer, env-doctor, codex-grade-coding, changelog-generator, truth-first, skill-creator and seo-optimizer. Install counts give a popularity signal that raw GitHub lists lack, and the marketplace format makes discovery and installation far easier than cloning repos. Like any marketplace, though, install counts measure attention rather than quality or safety — there is no security scanning or benchmarking, so the same read-before-install caution applies.

pricing 0

• + Easiest installation path of any option — one click per skill
• + Install counts provide a rough popularity signal missing from raw lists
• + Top skills are free and cover practical daily tasks (commits, PRs, reviews, env debugging)
• + Marketplace testing adds editorial curation

• − Install counts measure popularity, not safety or effectiveness
• − No security scanning, version pinning or benchmarks
• − Smaller curated surface than the big GitHub repos

marketingskills is the most focused marketing skill collection available, with 40-50 skills covering copywriting, SEO, CRO, paid ads, growth strategy, email sequences and landing-page optimisation — roughly 54k GitHub stars. Unlike general-purpose repos that happen to include a few marketing skills, this one was built by a marketer for marketers, and the difference shows in specificity: there is a real gap between 'write marketing copy' and 'write a Google Ads headline that fits character limits and includes the target keyword,' and this repo understands it. For a small business running its own marketing, it turns the repetitive parts of campaign creation, content briefs and conversion analysis into repeatable agent workflows. As a community repo it carries the usual caveats: no scanning, no benchmarks, read before you install.

pricing 0

• + Deepest marketing-specific collection, built by a marketer for marketers
• + Highly specific skills rather than generic 'write copy' prompts
• + Free and popular (~54k stars)
• + Practical for small businesses handling their own campaigns

• − Marketing-only; nothing for documents, dev or operations
• − No security scanning or benchmarks
• − Community-maintained with the usual audit-before-install caveat

squirrelscan/skills is a community collection built around website auditing, with 200+ rules covering security, SEO and related site-quality checks. It is a good example of the specialized single-domain repos that have grown up around the skills ecosystem: narrower than the big general collections, but deeper in its niche. For a small business that periodically needs its site checked — security issues, SEO problems, technical hygiene — pointing a coding agent at this collection turns a usually outsourced audit into an in-house workflow. Like other community repos, it is free and installed from GitHub, with no independent security scanning or benchmarking of its own.

pricing 0

• + Deep, focused website-audit coverage (200+ rules)
• + Turns site auditing into a repeatable agent workflow
• + Free and open source

• − Single-domain focus
• − No security scanning or benchmarks of its own
• − Community-maintained
