What it does
An agent skill by shadcn that audits a codebase and writes implementation plans for other agents to carry out. The idea is to use your most capable model for understanding the code and deciding what's worth doing, and hand the actual changes to cheaper models. It maps the repo, runs parallel sub-agents across categories such as correctness, security, performance, tests, tech debt and docs, re-checks each cited location to drop false positives, and shows a findings table ranked by impact and effort. You pick which findings become plans: self-contained markdown files in plans/ with exact steps, verification commands and stop conditions. Its README says the skill never edits source code itself. MIT licensed.
Who it's for
People using Claude Code, Codex, Cursor or another skills-capable agent who want a prioritized list of what to fix in a repo, written up so a cheaper model (or a person) can do the work.
How to set it up
Install it with the open skills CLI from your project folder:
bashnpx skills add shadcn/improveOpen your agent in the repo and run it in the agent's chat. quick is a cheaper pass that only covers hotspots and top findings:
text/improve /improve quickReply with the findings you want planned (for example "plan 1, 3 and 5"). Plans land in plans/ with an index and a recommended order. Other modes:
text/improve security /improve branch /improve plan <description> /improve execute <plan> /improve reconcileexecute hands a plan to a cheaper sub-agent in an isolated git worktree, then reviews the diff against the plan; merging stays up to you. reconcile checks which plans landed and refreshes the rest. Adding --issues also publishes plans as GitHub issues. According to the README, the skill itself only writes to plans/ and runs read-only commands in your working tree.

More Rules & Prompts
- Anthropic
Agent Skills (Anthropic)
Anthropic's public repository of Agent Skills: folders with a SKILL.md file (plus optional scripts and resources) that Claude loads when a task needs them. It includes example skills, the document skills behind Claude's file creation, a skill template and a copy of the Agent Skills spec (the open standard lives at agentskills.io). Many skills are Apache-2.0; the document skills are source-available, not open source.
- Agentic AI Foundation (Linux Foundation)
AGENTS.md
A simple open format for giving coding agents project instructions: one AGENTS.md markdown file in your repo with setup commands, test steps and code style. It is now stewarded by the Agentic AI Foundation under the Linux Foundation, and the agents.md site lists many tools that read it, including Codex, Cursor, goose, OpenCode, Aider, Zed, Kilo Code and GitHub Copilot's coding agent. The site and repo are MIT licensed. Claude Code reads it too when a project has no CLAUDE.md.
- Google (Android)
Android Skills
Google's official Agent Skills for Android development: SKILL.md instructions that ground coding agents in current Android guidance for tasks where Google's evaluations show LLMs underperform. Examples include migrating XML views to Jetpack Compose, upgrading to AGP 9, setting up Navigation 3, making an app edge-to-edge, auditing R8 configuration and fixing ANRs. They follow the open Agent Skills standard, so they work with Claude Code, Codex, Gemini/Antigravity and other agents that support skills. Apache-2.0.
- Anthropic
Anthropic Knowledge Work Plugins
Anthropic's open-source set of role plugins built for Claude Cowork that also install in Claude Code. Each plugin bundles slash commands, skills and connector (MCP) settings for one kind of work: sales, finance, data, legal, marketing, customer support, product management, engineering, design, HR, operations, bio research, small business and more. Plugins are plain Markdown and JSON, so you can read and edit them, or fork one as a template for your own team. The repository's marketplace also lists plugins from partners. Apache-2.0.
- Anthropic
Claude Code Plugins (official marketplace)
Anthropic's official plugin marketplace for Claude Code. A plugin bundles skills, subagents, hooks and MCP or LSP servers so you install them in one step. It lists plugins Anthropic maintains (such as commit-commands, code-review, feature-dev and the language-server plugins) alongside plugins from partners and other authors. Claude Code adds this marketplace for you the first time you start an interactive terminal session. The repo is Apache-2.0; each plugin has its own license.
- Cloudflare
Cloudflare Security Audit Skill
An agent skill from Cloudflare that runs a structured security audit of a codebase instead of a one-shot "look for bugs" prompt. It works in phases: map the architecture and keep a coverage ledger, hunt for issues area by area, have a fresh sub-agent try to validate each candidate, write findings as JSON checked against a schema (confirmed, needs validation or rejected), verify each record again, then produce a written report. Cloudflare says it grew out of the internal vulnerability harness described on its blog in June 2026. It is a single skill (security-audit), MIT licensed.
