Use when writing Elixir, Phoenix, or OTP code - routes to the correct thinking skill before any code is written
/plugin marketplace add georgeguimaraes/claude-code-elixir/plugin install georgeguimaraes-elixir-plugins-elixir@georgeguimaraes/claude-code-elixirThis skill inherits all available tools. When active, it can use any tool Claude has access to.
THIS IS NOT OPTIONAL. You cannot rationalize your way out of this. </EXTREMELY-IMPORTANT>
Elixir/Phoenix/OTP code → Invoke skill FIRST → Then write code
| Trigger Phrases | Skill to Invoke |
|---|---|
| code, implement, write, design, architecture, structure, pattern | elixir-thinking |
| LiveView, Plug, PubSub, mount, channel, socket, component | phoenix-thinking |
| context, schema, Ecto, changeset, preload, Repo, migration | ecto-thinking |
| GenServer, supervisor, Task, ETS, bottleneck, Broadway, Oban | otp-thinking |
These thoughts mean STOP—invoke the skill:
| Thought | Reality |
|---|---|
| "I'll add a process to organize this" | Processes are for runtime, not organization. |
| "GenServer is the Elixir way" | GenServer is a bottleneck by design. |
| "I'll query in mount" | mount is called twice. |
| "Task.async is simpler" | Use Task.Supervisor in production. |
| "I know Elixir well enough" | These skills contain paradigm shifts. Invoke them. |
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
