CloudflareSkillCloudflareSkillwrangler
cloudflare/skills/skills/wrangler/SKILL.md
Run or troubleshoot Wrangler CLI commands and configure Worker projects for local development, Previews, deployment, and Cloudflare resource management.
CloudflareSkillworkers-oauth-provider-migrate-1.0
cloudflare/workers-oauth-provider/skills/migrate-to-1.0/SKILL.md
Migrate a Cloudflare Worker from @cloudflare/workers-oauth-provider 0.x to 1.0. Use when upgrading that dependency, when OAuthProvider construction throws about resourceMetadata.resource or resourceMatchOriginOnly, or when asked to adopt the 1.0 role-based API (OAuthAuthorizationServer / OAuthResourceServer).
CloudflareSkillarchitecture
cloudflare/sandbox-sdk/.agents/skills/architecture/SKILL.md
Use when navigating the codebase for the first time, adding a new client method, adding a new container handler/service, or understanding how a request flows from Worker through the Sandbox DO into the container. Covers the three-layer architecture, client pattern, container runtime structure, and monorepo layout. (project)
CloudflareSkillchangesets
cloudflare/sandbox-sdk/.agents/skills/changesets/SKILL.md
Use when creating a changeset, preparing a release, or bumping versions. Covers which packages to reference, how to write user-facing changeset descriptions, the release automation flow, and the npm/Docker version sync requirement. (project)
CloudflareSkillcoding-standards
cloudflare/sandbox-sdk/.agents/skills/coding-standards/SKILL.md
Use when writing or reviewing TypeScript in this repo. Covers the no-`any` rule and where to put new types, the uppercase-acronym style guide, and the rules for code comments (no historical context). (project)
CloudflareSkillexamples
cloudflare/sandbox-sdk/.agents/skills/examples/SKILL.md
Use when working in the examples/ directory, running an example with wrangler dev, adding a new example, or answering questions about EXPOSE directives and the local Docker dev loop. (project)
CloudflareSkillgit-commit
cloudflare/sandbox-sdk/.agents/skills/git-commit/SKILL.md
Use when creating git commits to ensure commit messages follow project standards. Applies the 7 rules for great commit messages with focus on conciseness and imperative mood.
CloudflareSkilllogging
cloudflare/sandbox-sdk/.agents/skills/logging/SKILL.md
Use when adding logs, debugging, or working with the Logger across the SDK and container runtime. Covers the constructor-injection pattern, child loggers, env-var configuration, and test mocking. (project)
CloudflareSkillsandbox-bridge
cloudflare/sandbox-sdk/.agents/skills/sandbox-bridge/SKILL.md
Use when you need to exercise a real, running Sandbox deployment via HTTP — for example to validate SDK changes against a live container, reproduce a user-reported issue, or experiment with the API (including FUSE bucket mounts) without spinning up `wrangler dev`. Documents the Sandbox bridge worker reachable via `SANDBOX_WORKER_URL` + `SANDBOX_API_KEY` when the host injects them.
CloudflareSkillsession-execution
cloudflare/sandbox-sdk/.agents/skills/session-execution/SKILL.md
Use when working on or reviewing session execution, command handling, shell state, FIFO-based streaming, or stdout/stderr separation. Relevant for session.ts, command handlers, exec/execStream, or anything involving shell process management. (project)
CloudflareSkilltesting
cloudflare/sandbox-sdk/.agents/skills/testing/SKILL.md
Use when writing or running tests for this project. Covers unit vs E2E test decisions, test file locations, mock patterns, and project-specific testing conventions. (project)
CloudflareSkillartifact-fs
cloudflare/artifact-fs/.agents/skills/artifact-fs/SKILL.md
Mounts Git remotes with ArtifactFS as local working trees without a full clone. Use when asked to mount a remote repo, explain committed state versus dirty overlay state, or mount multiple repos under one daemon.
About skills
What is a Claude skill?
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.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
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.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
