Cover Letter Writer: Tailored, Human, and Under 300 Words
A recruiter-brained skill that reverse-engineers the job description's hiring priorities, maps them to real achievements from your resume, and writes a cover letter designed for the 6-second scan — no clichés, no invented facts.
Superpowers: The Spec-Driven Skill That Owns Your Whole Build
The most-starred agent skill on GitHub. Superpowers stops your agent from rushing in, works a spec out of the conversation, and hands a reviewed plan to subagents that build and check each other's work.
GStack: Give Your Agent a Whole Software Team's Worth of Roles
Garry Tan's Claude Code setup, ~110k stars. Instead of one mode, GStack gives your agent distinct roles — product vision, designer, engineering manager, QA, release manager — each behind its own slash command.
GSD Core: Ship Without Context Rot Using Atomic Plans
Git. Ship. Done. A spec-driven system that fights context rot by breaking work into atomic plans that run in fresh context windows, keeping your main session light while subagents do the heavy lifting.
grill-me: Make Your Agent Interview You Before It Writes Code
Matt Pocock's most popular skill. grill-me makes the agent interview you about what you're building before it writes anything — small, composable, and a deliberate stance against all-in-one systems that take away your control.
Agent Toolkit for AWS: Stop Letting Your Agent Half-Remember APIs
AWS's officially supported skills in the open format. Pair plugins for Claude Code and Codex with a curated skill collection and the AWS MCP Server so your agent loads service-specific guidance instead of guessing at an API.
skilld: Generate Version-Aware Skills From Your Own Dependencies
skilld generates version-aware skills from the npm dependencies you already have — pulling from docs, release notes, and GitHub issues — so your model stops writing last year's version of your library.
Ship Skills With Your Package: TanStack Intent + the Vercel Skills CLI
The newer idea: ship SKILL.md files inside your npm package, versioned with each release. TanStack Intent lets maintainers scaffold them; the Vercel skills CLI installs any of it across 70+ agents.
The Karpathy Guidelines: Four Rules That Stop Agents Going Sideways
174k stars for a single behavioral file. Think before coding, keep it simple, make surgical changes, stay focused on the goal. The low-commitment starting point if full workflows feel like too much.
Context Engineering: The Skill That Curates What Your Model Sees
Prompting is only half the job. Context engineering is the discipline of controlling exactly what enters the model's window — and what stays out — so your agent stays sharp across long sessions.
SEO Long-Form Writer: A Skill That Drafts 3,000-Word Articles That Rank
The exact skill I used to build this site's content engine. Give it a topic and a keyword and it researches, outlines, drafts, and self-edits a long-form article with proper structure, internal links, and schema.
Productized AI Service: Turn One Repeatable Workflow Into Recurring Income
The fastest path from AI skills to income isn't an app — it's a productized service. This skill walks your agent through scoping a niche offer, pricing it, and building the delivery system around an AI workflow.
AI Tool Curator: A Skill That Builds and Maintains Your Own Best-Of List
Curation is leverage. This skill helps your agent track, evaluate, and rank AI tools and skills against a consistent rubric — so you ship trustworthy 'best of' roundups instead of hype.
