121 SKILL.md files in Autonomous Agents. Most popular: Next.js Patterns, Build System Interaction, Hallucination Prevention. Every skill is a plain-Markdown SKILL.md you can copy or download for Claude Code, Codex and other AI agents.
Master Next.js patterns (App Router, server components, server actions, data fetching, middleware, route handlers, static generation, metadata) to build optimized, scalable apps.
Autonomously diagnose, configure, and optimize build tools and pipelines, interpret errors, and improve development vs production builds.
Grounds every claim in verifiable code and data, verifying facts, citing sources, and clearly flagging uncertainty to prevent hallucinations.
Output Verification systematically checks your work before delivery with tests, diffs, regression checks, and scope validation.
Evaluates risk before actions by classifying reversibility and blast radius to decide when to proceed, pause, or confirm.
Implements theme switching with CSS custom properties, system preference detection, and persistence for reliable dark/light modes.
Manage an autonomous agent's limited context window by triaging, summarizing, and organizing information to maximize relevance density during reasoning.
Generates clean, well-structured Markdown documents with proper headings, code blocks, tables, links, images, escaping, and linting.
Interleaves reasoning and a single action to solve problems with a clear reasoning trace; use it for structured, iterative problem solving.
Install, configure, and run natural-language end-to-end browser tests with DevAssure CLI. Supports YAML test cases, CI/CD integration, Excel tests. The agent picks up the tests ...
Creates robust, defensive API integrations: auth, rate limits, backoff retries, error handling, and versioning.
Reads, edits, and creates configuration files with precision, preserving formatting and comments while applying environment-specific conventions.
Writes and maintains scalable, predictable CSS architecture tailored to project methodology (BEM, CSS Modules, CSS-in-JS, theming, and responsive design).
Generates accurate, near-code documentation during development—README structure, inline comments, API docs, ADRs, and changelogs.
Performs advanced Git operations (rebase, cherry-pick, bisect, stash, submodules, worktrees, reflog, hooks) to manage complex workflows; use for clean history and safe recovery.
Guides autonomous agents to use git safely with one-change commits, file-specific staging, meaningful messages, and careful branch/merge handling.
Reads and interprets application logs to identify errors, patterns, and actionable insights for root-cause analysis.
Plan before coding to analyze requirements, identify risks and unknowns, choose architecture, and map file changes for safer, faster development.
Generates clear, cadence-based progress updates for long tasks, detailing milestones, current status, and next steps to keep users informed without overload.
Craft correct, readable, and efficient regular expressions for text tasks, with backtracking-safe patterns and testing guidance.
Equips autonomous agents with self-monitoring to detect, diagnose, and recover from mistakes, preventing cascading failures during execution.
Finds code by meaning and patterns, not just text, helping you locate authentication, config, or auth-related logic across codebases.
Design and build serverless apps with event-driven patterns, cold-start optimization, state management, and automated deployment.
Generates machine-readable outputs (JSON, YAML, TOML) that are syntactically valid, schema-compliant, and ready for downstream consumption.
Build fast, scalable data tables and lists with virtualization, sorting, filtering, responsive layouts, and proper empty/loading states for large datasets.
