> lucia-auth

You are an expert in Lucia, the lightweight authentication library for TypeScript. You help developers implement session-based authentication with email/password, OAuth (Google, GitHub, Discord), magic links, and two-factor authentication — providing a simple, database-agnostic auth layer that you understand and control, without the complexity of full auth platforms.

Secure webhook endpoints. Use when a user asks to verify webhook signatures, prevent replay attacks, handle webhook retries, or implement secure webhook receivers for Stripe, GitHub, Slack, or any provider.

> argocd

Argo CD for GitOps continuous delivery on Kubernetes. Use when the user needs to define applications declaratively, sync Kubernetes manifests from Git repositories, manage sync policies, and implement progressive delivery workflows.

> authjs

You are an expert in Auth.js (formerly NextAuth.js), the authentication library for web frameworks. You help developers add sign-in with 80+ OAuth providers (Google, GitHub, Apple, Discord), email/password, magic links, and WebAuthn to Next.js, SvelteKit, Express, and other frameworks — with session management, JWT/database sessions, role-based access, and middleware protection.

> coderabbit

Automate code reviews with CodeRabbit, the AI-powered review tool. Use when a user asks to set up automated PR reviews, configure review rules, integrate with GitHub or GitLab, customize review instructions, or manage CodeRabbit settings.

> planetscale

Expert guidance for PlanetScale, the serverless MySQL platform built on Vitess (the database clustering system powering YouTube). Helps developers set up databases with Git-like branching for schema changes, non-blocking schema migrations, and connection pooling for serverless environments.

> porter

Expert guidance for Porter, the platform that provides a Heroku-like experience on your own AWS, GCP, or Azure account. Helps developers deploy applications on managed Kubernetes clusters provisioned in their own cloud accounts, with the simplicity of `git push` deployment and the control of owning your infrastructure.

> aider

You are an expert in Aider, the terminal-based AI coding assistant that reads your codebase, makes changes across multiple files, and creates proper git commits. You help developers use Aider for autonomous code generation, refactoring, bug fixing, and test writing — working with any LLM (Claude, GPT-4, Gemini, local models) while respecting project conventions and maintaining git history.

> lefthook

Fast Git hooks manager written in Go. Use when a user asks to set up Git hooks without Node.js dependency, run parallel pre-commit checks, or find a faster alternative to Husky.

> koyeb

Expert guidance for Koyeb, the serverless cloud platform for deploying full-stack applications, APIs, and workers globally with automatic scaling, built-in CI/CD, and edge networking. Helps developers deploy applications from Git or Docker with zero-downtime deployments and pay-per-use pricing.

> act

Run GitHub Actions locally with act. Use when a user asks to test GitHub Actions workflows locally, debug CI pipelines without pushing, or run workflows offline.

> bitbucket

Manage repositories, pipelines, and code review with Bitbucket Cloud. Use when a user asks to set up Bitbucket repositories, configure Bitbucket Pipelines for CI/CD, manage pull requests, set up branch permissions, use Bitbucket REST API 2.0, create webhooks, manage deployment environments, set up code review workflows, integrate with Jira, configure merge checks, or automate repository operations. Covers repository management, CI/CD pipelines, code review, deployments, and Atlassian ecosystem i

> mkdocs

Build documentation sites with MkDocs and Material for MkDocs. Use when a user asks to create project documentation, configure MkDocs themes, add search and navigation, deploy docs to GitHub Pages, or customize Markdown extensions.

> webhook-processor

Build and configure webhook processing systems with retry logic, signature verification, and dead letter queues. Use when you need to receive, validate, and reliably process incoming webhooks from payment providers, version control platforms, or third-party APIs. Trigger words: webhook, callback URL, event handler, retry, idempotency, payload processing.

> husky

Run scripts on Git hooks with Husky. Use when a user asks to run linters before commit, validate commit messages, run tests before push, or set up Git hooks for a team.

> ai-eval-ci

Run AI agent and LLM evaluations in CI/CD pipelines — automated quality gates that fail the build when AI output quality drops. Use when someone asks to "test my AI agent", "add evals to CI", "catch prompt regressions", "compare models", "evaluate LLM output quality", "set up AI quality gates", or "benchmark my agent before deploying". Covers eval frameworks (Cobalt, Promptfoo, Braintrust), LLM-as-judge scoring, threshold-based assertions, and GitHub Actions integration.

> gh-fix-ci

Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions; use `gh` to inspect checks and logs, summarize failure context, draft a fix plan, and implement only after explicit approval. Treat external providers (for example Buildkite) as out of scope and report only the details URL.
