All Skills

This skill should be used when selecting CrewAI built-in tools, composing agent toolchains, or creating production-ready custom tools with BaseTool or @tool, including schema validation, dependency management, caching, async support, and testing.

Generates project-specific .claude/commands for Claude Code

Upgrades npm/yarn/pnpm dependencies with breaking change handling

Quantitative scoring of niche viability for lifestyle SaaS ($1-3M ARR, solo/duo team). Use after completing a first-pass evaluation to generate a weighted score and go/no-go decision. Triggers on requests like "score this niche", "rate this opportunity", "should I pursue this", or "give me a scorecard for [niche]". Produces a 0-100 weighted score with clear decision thresholds.

Drift-detect and sync git-tracked .claude/ and .codex/ config from project to home. Default shows what would change; "apply" performs the sync.

This skill should be used when the user asks to "create a model", "add a Django model", "create database table", "add entity", "define schema", or when writing class definitions inheriting from models.Model. Validates BaseModel inheritance pattern.

Coordinates dependency upgrades across all detected package managers

This skill should be used when the user asks to "write tests first", "run TDD", "verify red phase", "check failing tests", or when practicing test-driven development. Ensures tests fail before implementation.

Write, review, and improve Minitest tests for Ruby on Rails applications. Covers model tests, controller tests, system tests, fixtures, and best practices from Rails Testing Guide.

Creates test infrastructure with Vitest, xUnit, and pytest

Analyze agent skills for security risks, malicious patterns, and potential dangers before installation. Use when asked to "audit a skill", "check if a skill is safe", "analyze skill security", "review skill risk", "should I install this skill", "is this skill safe", or when evaluating any skill directory for trust and safety. Also triggers when the user pastes a skill install command like "npx skills add https://github.com/org/repo --skill name". Produces a comprehensive security report with a clear install/reject verdict.

Create a git commit from current staged and unstaged changes with an appropriate commit message.

API contract audit worker (L3). Checks layer leakage in method signatures, missing DTOs, entity leakage to API, inconsistent error contracts, redundant method overloads. Returns findings with penalty-based scoring + diagnostic sub-scores.

This skill should be used when the user asks to "design multi-agent system", "implement supervisor pattern", "create swarm architecture", "coordinate multiple agents", or mentions multi-agent patterns, context isolation, agent handoffs, sub-agents, or parallel agent execution.

Shared state and template helper skill for BMAD. Provides reusable YAML contracts and deterministic scripts used by orchestrator and phase skills.

Controller actions, routing, REST conventions, filters, and response handling

Build CLI applications using React. Use when creating terminal UIs, handling keyboard input, or building interactive command-line tools with React components. Supports flexbox layouts, text styling, focus management, and accessibility.

Application lifecycle audit worker (L3). Checks bootstrap initialization order, graceful shutdown, resource cleanup, signal handling, liveness/readiness probes. Returns findings with severity, location, effort, recommendations.

Restructure project documentation for clarity and accessibility. Use when users ask to "organize docs", "generate documentation", "improve doc structure", "restructure README", or need to reorganize scattered documentation into a coherent structure. Analyzes project type and creates appropriate documentation hierarchy.

This skill activates when writing Hono routes, handlers, middleware, or discussing Hono application architecture. It provides patterns for routing, middleware composition, error handling, and TypeScript integration.

Analyze Claude Code session bloat — shows token count, context usage %, and bloat breakdown. Use when the user asks about session size, context usage, or when you notice the context window is getting full.

This skill should be used when working with single-cell omics data analysis using scvi-tools, including scRNA-seq, scATAC-seq, CITE-seq, spatial transcriptomics, and other single-cell modalities. Use this skill for probabilistic modeling, batch correction, dimensionality reduction, differential expression, cell type annotation, multimodal integration, and spatial analysis tasks.

Build DAG workflows with Mastra 1.x (@mastra/core/workflows). Use when implementing workflow orchestration with directed acyclic graphs, step chaining, parallel execution, branching, loops, error handling, suspend/resume, or streaming. Triggers on tasks involving createStep, createWorkflow, .then(), .parallel(), .branch(), .foreach(), .dountil(), .dowhile(), .map(), workflow state management, or Mastra step composition.

Use when documentation needs to be updated, clarified, or reorganized to better serve users' jobs-to-be-done with low cognitive load and high signal.
