From elixir-phoenix
Provides examples, walkthroughs, official guides, and plugin-specific patterns for Phoenix, LiveView, Ecto, and OTP. Use for 'how do I...', 'show me an example', or 'what does X look like' queries.

For standard implementation patterns, always check official guides first:
Generates design tokens/docs from CSS/Tailwind/styled-components codebases, audits visual consistency across 10 dimensions, detects AI slop in UI.
Records polished WebM UI demo videos of web apps using Playwright with cursor overlay, natural pacing, and three-phase scripting. Activates for demo, walkthrough, screen recording, or tutorial requests.
Delivers idiomatic Kotlin patterns for null safety, immutability, sealed classes, coroutines, Flows, extensions, DSL builders, and Gradle DSL. Use when writing, reviewing, refactoring, or designing Kotlin code.
For standard implementation patterns, always check official guides first:
| Topic | Guide |
|---|---|
| Contexts | hexdocs.pm/phoenix/contexts |
| Ecto Basics | hexdocs.pm/phoenix/ecto |
| LiveView | hexdocs.pm/phoenix_live_view |
| Authentication | mix phx.gen.auth |
| Channels | hexdocs.pm/phoenix/channels |
| Testing | hexdocs.pm/phoenix/testing |
| Deployment | hexdocs.pm/phoenix/deployment |
Patterns NOT in official guides (unique to this plugin):
# 1. Check if Tidewave is running
/mcp
# 2. If connected, debug with runtime tools
# Get exact docs for YOUR dependency versions
mcp__tidewave__get_docs "Ecto.Query"
# Execute code in running app
mcp__tidewave__project_eval "MyApp.Accounts.list_users() |> length()"
# Query database directly
mcp__tidewave__execute_sql_query "SELECT count(*) FROM users"
# 1. Plan feature with specialist agents
/phx:plan Add user avatars with S3 upload
# 2. After implementation, review with multiple perspectives
/phx:review lib/my_app/accounts.ex # Elixir idioms
# Security analyzer runs automatically on auth code
# 3. Before deployment
# Deployment validator checks production readiness
This plugin enforces non-negotiable rules across all agents:
Elixir Idioms:
LiveView:
Oban:
Security:
# 1. Start with obvious checks
/phx:investigate Login failing after password reset
# 2. Agent checks Ralph Wiggum list:
# - File saved? Compiled? Migrated?
# - Atom vs string keys?
# - Data preloaded?
# 3. If complex, escalate to Ralph Wiggum Loop (if installed)
/ralph-loop:ralph-loop "Fix login tests. Output <promise>DONE</promise> when green."
# 1. Research phase
/phx:research Oban unique jobs best practices
# 2. Plan with context analysis
/phx:plan Add daily digest email job
# 3. Agents coordinate:
# - hex-library-researcher evaluates deps
# - oban-specialist designs worker
# - ecto-schema-designer plans data model
# 1. Run security analyzer on auth code
/phx:review lib/my_app_web/controllers/session_controller.ex
# 2. Check for common vulnerabilities:
# - SQL injection (parameterized queries?)
# - XSS (proper escaping?)
# - CSRF (tokens present?)
# - Authorization (re-checked in events?)
