Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
CloudflareSkillcloudflare/security-audit-skill/skills/security-audit/SKILL.md
Security guidance and vulnerability review for codebases, APIs, services, CLI tools, libraries, and daemons. Use for security questions, focused reviews, vulnerability research, security audits, or pen tests. Run the complete workflow only for explicit codebase audit or pen-test requests, full/comprehensive/end-to-end reviews, or requested report artifacts.
CloudflareSkillcloudflare/quiche/.codex/skills/quiche-draft-release/SKILL.md
quiche draft GitHub release automation from a release commit hash or existing tag. Use when creating draft releases for the quiche crate from a quiche/Cargo.toml version bump.
CloudflareSkillcloudflare/cloudflare-os/.agents/skills/frontend-conventions/SKILL.md
Use for creating, modifying, moving, or reviewing React frontend code anywhere in packages/*, including Workshop pages, gatekeeper management apps, shared UI, components, hooks, forms, interactions, styling, accessibility, and frontend tests.
CloudflareSkillcloudflare/cloudflare-os/.agents/skills/write-gatekeeper/SKILL.md
Guides implementation of Gatekeeper Workers that bridge Gadgets to external services. Covers auth, capability-based API design, approval queue integration, caching, and action simulation. Load when creating, modifying, or reviewing the implementation of a gatekeeper.
CloudflareSkillcloudflare/moltworker/skills/cloudflare-browser/SKILL.md
Control headless Chrome via Cloudflare Browser Rendering CDP WebSocket. Use for screenshots, page navigation, scraping, and video capture when browser automation is needed in a Cloudflare Workers environment. Requires CDP_SECRET env var and cdpUrl configured in browser.profiles.
CloudflareSkillcloudflare/computer/.agents/skills/capnweb/SKILL.md
capnweb RPC patterns for this repo, with a heavy focus on stub lifecycle and disposal. Load when touching anything that crosses the Durable Object ↔ computerd boundary: packages/rpc, packages/computer, the computerd client, or the Durable Object server. Triggers include "capnweb", "RpcTarget", "stub", "RPC wire", "promise pipelining", "stub disposal", "RpcPromise".
CloudflareSkillcloudflare/computer/.agents/skills/cloudflare/SKILL.md
Index of Cloudflare-platform skills relevant to this repo. Load when working on anything that touches Workers, Durable Objects, wrangler, the sandbox SDK, the agents SDK, or other Cloudflare platform surface. Triggers include "Cloudflare", "Workers", "Durable Object", "wrangler", "KV", "R2", "D1", "Vectorize", "Containers", "sandbox".
CloudflareSkillcloudflare/computer/.agents/skills/debugging-computerd-fuse/SKILL.md
Debug computerd in real-FUSE mode end-to-end without workerd, vitest-pool-workers, or wrangler in the loop. Boot the linux-x64 binary in a privileged docker container, drive its capnweb /api endpoint from Node, simulate DO-side sync from a SQLiteTestStorage, and isolate FUSE-related deadlocks. Load when a real-FUSE bug reproduces locally but unit tests pass, when the harness vitest tests hang against a real container, or when you need to attribute a wedge to FUSE vs sync vs exec.
CloudflareSkillcloudflare/computer/.agents/skills/prose/SKILL.md
Style guidance for the written word. Use when asked to write code comments, commit messages, pull requests, READMEs, or documentation. Triggers might be phrases like "write a commit", "document this", or "add a README".
CloudflareSkillcloudflare/computer/.agents/skills/pull-requests/SKILL.md
Describes how to write pull/merge requests. Use when asked to write or edit a pull request or merge request description. This skill is not relevant to commit messages.
CloudflareSkillcloudflare/computer/.agents/skills/test-driven-development/SKILL.md
Drives development with tests. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality.
CloudflareSkillcloudflare/vinext/.agents/skills/migrate-to-vinext/SKILL.md
Migrates Next.js projects to vinext (Vite-based Next.js reimplementation). Load when asked to migrate, convert, or switch from Next.js to vinext. Handles compatibility scanning, package replacement, Vite config generation, ESM conversion, and deployment setup (Cloudflare Workers natively, other platforms via Nitro).
CloudflareSkillcloudflare/workerd/.opencode/skills/bazel-test-hygiene/SKILL.md
Mandatory rules for running bazel tests during development. Load this skill before running any bazel test command, especially when validating fixes or verifying regression tests. Prevents false confidence from cached results, filter flags that silently match nothing, and partial test runs that miss breakage.
CloudflareSkillcloudflare/workerd/.opencode/skills/commit-categories/SKILL.md
Commit categorization rules for changelogs and "what's new" summaries. MUST be loaded before categorizing commits in changelog or whats-new commands. Provides the canonical path-based category table used to group commits by area.
CloudflareSkillcloudflare/workerd/.opencode/skills/dad-jokes/SKILL.md
After completing any task that took more than ~5 tool calls, or after long-running builds/tests finish, load this skill and deliver a dad joke to lighten the mood. Also load before any user-requested joke, pun, or limerick. Never improvise jokes without loading this skill first.
CloudflareSkillcloudflare/workerd/.opencode/skills/find-and-run-tests/SKILL.md
How to find, build, and run tests in workerd. Covers wd-test, kj_test target naming, bazel query patterns, and common flags. Also covers parent project integration tests if workerd is used as a submodule. Load this skill when you need to locate or run a test and aren't sure of the exact target name or invocation.
CloudflareSkillcloudflare/workerd/.opencode/skills/identify-reviewer/SKILL.md
Identifies the local user's GitHub account and git identity before performing code reviews. Load this skill at the start of any PR review, code review, or commit log analysis so findings can be framed relative to the user's own prior comments, commits, and approval status.
CloudflareSkillcloudflare/workerd/.opencode/skills/investigation-notes/SKILL.md
Structured scratch tracking document for investigation state during bug hunts - prevents re-reading code, losing context, and rabbit holes; maintains external memory so you don't re-derive conclusions
CloudflareSkillcloudflare/workerd/.opencode/skills/kj-style/SKILL.md
KJ/workerd C++ style guidelines for code review. Covers naming, type usage, memory management, error handling, inheritance, constness, and formatting conventions. Load this skill when reviewing or writing C++ code in the workerd codebase.
CloudflareSkillcloudflare/workerd/.opencode/skills/markdown-drafts/SKILL.md
Use markdown formatting when drafting content intended for external systems (GitHub issues/PRs, Jira tickets, wiki pages, design docs, etc.) so formatting is preserved when the user copies it. Load this skill before producing any draft the user will paste elsewhere.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
