What it does
OAuth Implementation is an agent skill from secondsky/claude-skills. OAuth 2.0 and OpenID Connect authentication with secure flows. Use for third-party integrations, SSO systems, token-based API access, or encountering authorization code flow, PKCE, token refresh, scope management errors.
Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/python-java.md`).
It sits in Backend & APIs, covering OAuth and OpenID Connect. It works with Java and Python. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.
When your agent uses it
- Third-party integrations
- Token-based API access
- Encountering authorization code flow
- Scope management errors
Example prompts
- “/oauth-implementation”
Requirements
- Python 3
- A credential in CLIENT_SECRET
What it can do on your machine
Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
CLIENT_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
OAuth Implementation loads about 693 tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 120 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

OAuth Implementation
Implement OAuth 2.0 and OpenID Connect for secure authentication.
OAuth 2.0 Flows
| Flow | Use Case |
|---|---|
| Authorization Code | Web apps (most secure) |
| Authorization Code + PKCE | SPAs, mobile apps |
| Client Credentials | Service-to-service |
| Refresh Token | Session renewal |
Authorization Code Flow (Express)
const express = require('express');
const jwt = require('jsonwebtoken');
// Step 1: Redirect to authorization
app.get('/auth/login', (req, res) => {
const state = crypto.randomBytes(16).toString('hex');
req.session.oauthState = state;
const params = new URLSearchParams({
client_id: process.env.CLIENT_ID,
redirect_uri: process.env.REDIRECT_URI,
response_type: 'code',
scope: 'openid profile email',
state
});
res.redirect(`${PROVIDER_URL}/authorize?${params}`);
});
// Step 2: Handle callback
app.get('/auth/callback', async (req, res) => {
if (req.query.state !== req.session.oauthState) {
return res.status(400).json({ error: 'Invalid state' });
}
const tokenResponse = await fetch(`${PROVIDER_URL}/token`, {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: new URLSearchParams({
grant_type: 'authorization_code',
code: req.query.code,
redirect_uri: process.env.REDIRECT_URI,
client_id: process.env.CLIENT_ID,
client_secret: process.env.CLIENT_SECRET
})
});
const tokens = await tokenResponse.json();
// Store tokens securely and create session
});PKCE for Public Clients
function generatePKCE() {
const verifier = crypto.randomBytes(32).toString('base64url');
const challenge = crypto
.createHash('sha256')
.update(verifier)
.digest('base64url');
return { verifier, challenge };
}Security Requirements
- Always use HTTPS
- Validate redirect URIs strictly
- Use PKCE for public clients
- Store tokens in HttpOnly cookies
- Implement token rotation
- Use short-lived access tokens (15 min)
Additional Implementations
See references/python-java.md for:
- Python Flask with Authlib OIDC provider
- OpenID Connect discovery and JWKS endpoints
- Java Spring Security OAuth2 server
- Token introspection and revocation
Never Do
- Store tokens in localStorage
- Use implicit flow
- Skip state parameter validation
- Expose client secrets in frontend
- Use long-lived access tokens
