CI/CD

FastMCP Cloud deployment validation, testing, and verification patterns. Use when deploying MCP servers, validating deployments, testing server configurations, checking environment variables, verifying deployment health, tracking deployments, or when user mentions FastMCP Cloud, deployment validation, pre-deployment checks, post-deployment verification, deployment troubleshooting, or deployment lifecycle management.

Analyzes dbt model dependencies, traces upstream sources and downstream consumers, identifies circular dependencies, and visualizes data lineage. Use when user asks about model dependencies, wants to understand data flow, needs impact analysis, or wants to trace where data comes from or goes to.

Data validation with Malli schemas in Clojure. Use when working with: (0)malli, (1) data validation or coercion, (2) defining schemas for maps,collections, or domain models, (3) API request/response validation, (4) formvalidation, (5) runtime type checking, or when the user mentions malli,schemas, validation, data contracts, or data integrity.

WHEN: Code review, quality check, code smell detection, refactoring suggestionsWHAT: Complexity analysis + code smell list + severity-based issues + improvement suggestionsWHEN NOT: Next.js specific → nextjs-reviewer, Security → security-scanner, Performance → perf-analyzer

Find notes that two specified notes both link to (common neighbors). Triggers on "common references", "shared links", "what do X and Y both link to", "common neighbors".

Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Guides creation of ChatGPT Apps with interactive widgets using OpenAI Apps SDK and MCP servers.Use when building ChatGPT custom apps with visual UI components, embedded widgets, or richinteractive experiences. Covers widget architecture, MCP server setup with FastMCP, responsemetadata, and Developer Mode configuration. NOT when building standard MCP servers withoutwidgets (use building-mcp-servers skill instead).

Use when integrating MCP servers with Claude Code plugins - MCP configuration with transport types, scopes, and tool naming for November 2025 specifications

Generates complete, runnable RSpec tests for Rails models, services, controllers, and background jobs following project conventions. Use when new code is created without corresponding tests, when refactoring existing code, or when explicitly asked to add test coverage.

Financial systems and cost engineering

Best practices for creating Claude Code slash commands. Use this skill when creating, editing, or improving custom slash commands for Claude Code. Covers frontmatter configuration, dynamic features ($ARGUMENTS, bash execution, file references), command patterns (git workflows, multi-agent orchestration, code review), and helps decide when to use slash commands vs skills vs subagents.

Next.js 15 API route patterns, NextRequest, NextResponse, error handling, maxDuration configuration, authentication, request validation, server-side operations, route handlers, and API endpoint best practices. Use when creating API routes, handling requests, configuring timeouts, or building server-side endpoints.

Advanced tmux operations bundle for Miyabi multi-agent AI orchestration.Includes auto-recovery, health monitoring, task queue integration, and MCP server coordination. The definitive skill for AI agent workflows.

Update and clean up project documentation files (primarily .ai/features/, but also README.md, PROGRESS_TRACKER.md, CLAUDE.md, and other .md files). Use when user requests documentation cleanup, organization, or updates for any feature, module, or project documentation (e.g., 'update photo viewer docs', 'clean up README', 'organize documentation'). Removes code snippets, outdated details, and redundant information while preserving essential architectural decisions and technical context.

Selects and configures agents from the agents repo based on PRD tech stack.Runs after task decomposition, before specification generation.

Time series differencing for stationarity and trend removal

Optimiza políticas RLS de Supabase usando el patrón (select auth.uid()) para mejor performance. Usa cuando trabajes con RLS policies, auth.uid() reevaluación, o tareas 1.3 y 2.1 del PLAN_MEJORAS.md.

Apply wave physics principles when working on simulation code. Use this skill when editing files in src/waves/, src/simulation/, or when the user mentions wave behavior, shoaling, breaking, or foam physics.

Industrial-strength NLP with spaCy 3.x for text processing and custom classifier training. Use when: installing spaCy, selecting models (en_core_web_sm/md/lg/trf), tokenization, POS tagging, named entity recognition, dependency parsing, training TextCategorizer models, troubleshooting errors (E050/E941 model errors, E927 version mismatch, memory issues), batch processing with nlp.pipe, or deploying models to production. Includes data preparation scripts, config templates, and FastAPI serving examples.
