LLM & Agents

Use when nim-C interoperability including calling C from Nim, wrapping C libraries, importc/exportc pragmas, header generation, FFI patterns, and building high-performance systems code integrating Nim with existing C codebases.

Use when integrating tools, permissions, and MCP servers with Claude AI agents using the Agent SDK.

Use when writing or creating new Standard Operating Procedures (SOPs) for AI agents. Covers effective SOP writing, clarity principles, and actionable instruction design.

Reconcile workflow state files to ensure checkpoints are properly updated. Use when state files are out of sync, after subagent completion without handoff, when switching workflows, or when user runs /reconcile command.

Use when scala collections including immutable/mutable variants, List, Vector, Set, Map operations, collection transformations, lazy evaluation with views, parallel collections, and custom collection builders for efficient data processing.

Use when nim's metaprogramming including macros, templates, compile-time evaluation, AST manipulation, code generation, DSL creation, and leveraging compile-time computation for performance and abstraction in systems programming.

Use when gleam-Erlang interoperability including calling Erlang code from Gleam, using Erlang libraries, external functions, working with Erlang types, NIFs, and leveraging the BEAM ecosystem from Gleam applications.

Use when managing agent context, memory, and conversation state in Claude AI agents using the Agent SDK.

Orchestrator for WebView UI mockup workflow - delegates design iteration to ui-design-agent and implementation scaffolding to ui-finalization-agent. Use when user mentions UI design, mockup, WebView interface, or requests 'design UI for [plugin]'.

Use when advanced Pytest features including markers, custom assertions, hooks, and coverage configuration.

Validates and configures all dependencies required for the Plugin Freedom System. This is a STANDALONE skill that runs BEFORE plugin workflows begin. It checks for Python, build tools, CMake, JUCE, and pluginval, optionally installing missing dependencies with user approval. Configuration is saved to .claude/system-config.json for use by other skills. Use when user mentions setup, installation, dependencies, missing tools, or when SessionStart hook detects configuration issues.

Orchestrates Stage 0 research and planning for JUCE plugins - creates architecture.md and plan.md contracts through subagent delegation. Use when creative brief exists and plugin needs DSP architecture specification, complexity assessment, or implementation planning. Invoke via /plan command, natural language (plan architecture, research DSP), or as first implementation step.

This skill should be used when crafting prompts for Nano Banana Pro (Gemini image generation). Use when users want help writing image generation prompts, need guidance on prompt structure, or want to optimize their prompts for better results.

Use when Elixir OTP patterns including GenServer, Supervisor, Agent, and Task. Use when building concurrent, fault-tolerant Elixir applications.

Use when relay fragment composition, data masking, colocation, and container patterns for React applications.

Use when modifying, removing, or refactoring code that lacks test coverage. Emphasizes the danger of untested changes and the RGR workflow to add characterization tests before modifications.

Orchestrates JUCE plugin implementation through stages 1-3 (Foundation, DSP, GUI) using subagent delegation with automatic validation after each stage. Use when implementing plugins after planning completes, or when resuming with /continue command. Invoked by /implement command.

Multi-agent parallel investigation for complex JUCE problems. Use when troubleshooting fails after Level 3, problems require novel research, or user requests /research command.

Use when writing SOPs that require precise requirement levels using RFC 2119 constraint keywords (MUST, SHOULD, MAY). Covers proper usage of requirement keywords for deterministic agent behavior.

Validates audio plugins through automated tests, pluginval, or manual DAW testing. Use for MANUAL testing via /test command. Note - Automatic validation now built into workflow (validation-agent runs after each stage). This skill is for manual testing only, after bug fixes, or when user mentions test, validate, validation, pluginval, stability, automated tests, run tests, check plugin, or quality assurance.
