teak: Skill for Codex

.agents/skills/convex-setup-auth/SKILL.md

convex-setup-auth is a skill for Codex from praveenjuge/teak. It costs 40 tokens per session (1,609 once invoked), scanned A, a copy of convex-setup-auth, MIT.

A setup skill for adding login, user identity mapping, and permission checks to a Convex application. Convex is a backend platform that provides database and server functions.

In plain words
What is it for?
Use it when configuring an authentication provider, user tables, protected functions, or roles in Convex. It supports Convex Auth, Clerk, WorkOS AuthKit, Auth0, and custom JWT setups.
Why use it?
It helps connect users to Convex records and protect backend operations from unauthorized access.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is praveenjuge/teak's own configuration. It tells Codex how to work on teak itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything teak configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

convex-setup-auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Convex Authentication Setup

Implement secure authentication in Convex with user management and access control.

When to Use

  • Setting up authentication for the first time
  • Implementing user management (users table, identity mapping)
  • Creating authentication helper functions
  • Setting up auth providers (Convex Auth, Clerk, WorkOS AuthKit, Auth0, custom JWT)

When Not to Use

  • Auth for a non-Convex backend
  • Pure OAuth/OIDC documentation without a Convex implementation
  • Debugging unrelated bugs that happen to surface near auth code
  • The auth provider is already fully configured and the user only needs a one-line fix

First Step: Choose the Auth Provider

Convex supports multiple authentication approaches. Do not assume a provider.

Before writing setup code:

  1. Ask the user which auth solution they want, unless the repository already makes it obvious
  2. If the repo already uses a provider, continue with that provider unless the user wants to switch
  3. If the user has not chosen a provider and the repo does not make it obvious, ask before proceeding

Common options:

  • Convex Auth - good default when the user wants auth handled directly in Convex
  • Clerk - use when the app already uses Clerk or the user wants Clerk's hosted auth features
  • WorkOS AuthKit - use when the app already uses WorkOS or the user wants AuthKit specifically
  • Auth0 - use when the app already uses Auth0
  • Custom JWT provider - use when integrating an existing auth system not covered above

Look for signals in the repo before asking:

  • Dependencies such as @clerk/*, @workos-inc/*, @auth0/*, or Convex Auth packages
  • Existing files such as convex/auth.config.ts, auth middleware, provider wrappers, or login components
  • Environment variables that clearly point at a provider

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
