D2 Modern Diagram Scripting Language and CLI
D2 is a modern diagram scripting language that turns text into diagrams. It compiles declarative text files into SVG, PNG, and PDF outputs with automatic layout, multiple themes, and support for sequence diagrams, class diagrams, and network topologies.
Cypress Visual Regression Testing Suite
Automates pixel-level visual regression testing using Cypress with cypress-image-snapshot plugin. Compares screenshots against baselines using pixelmatch algorithm with configurable diff thresholds.
Cypress Visual Regression Runner
Runs visual regression tests comparing screenshots captured via Cypress cy.screenshot() against baseline images using pixelmatch diffing. Integrates with Percy SDK for cross-browser visual snapshots.
Cypress Network Stub Generator
Generates cy.intercept() stubs from recorded HAR files for deterministic E2E tests. Uses cy.session() for authentication caching and cy.origin() for cross-origin testing workflows.
Cypress End-to-End and Component Testing Framework
Cypress is an open-source browser testing framework for end-to-end, component, and accessibility testing in modern web apps. It gives agents and developers a reliable way to run local browser tests, debug failures with rich traces, and plug test execution into CI pipelines.
Cypress E2E Test Generator
Generates Cypress end-to-end test suites from user flow recordings. Uses the Cypress Real Events plugin and cy.intercept() for network stubbing with automatic fixture generation.
Cypress E2E API Intercept Skill
Creates end-to-end tests with Cypress cy.intercept() for API mocking and cy.wait() for request assertion. Uses Cypress Testing Library queries with findByRole() and findByText() for accessible element selection.
Cypress Component Testing Toolkit
Creates component and integration tests using the Cypress Testing Library API and cy.intercept for network stubbing. Supports visual testing via the Cypress Image Snapshot plugin and accessibility auditing with cypress-axe.
Cypress Component Testing Suite
Implements component and E2E tests using Cypress with cy.mount, cy.intercept, and cy.get selectors. Configures cypress.config.ts with component devServer, custom commands, and Mochawesome reporter integration.
Cypress Component Testing Framework
Scaffolds Cypress component tests for React, Vue, and Angular apps using the Cypress CT mount API. Configures webpack/vite dev servers and generates snapshot-based visual assertions.
Cypress Component Test Generator
Auto-generates Cypress component tests from React and Vue source files using AST parsing. Produces mount, interaction, and accessibility test cases.
CycloneDX SBOM Generator
Generates Software Bill of Materials in CycloneDX format using cdxgen and Syft. Scans npm, pip, and Go modules for known CVEs via OSV.dev API integration.
csvkit Python CSV Utility Suite
csvkit is a suite of Python command-line utilities for converting to, working with, and analyzing CSV files. It includes tools for format conversion, querying CSV with SQL, data cleaning, filtering, sorting, and statistical analysis.
CSV Schema Validator & Auto-Fixer
Validates CSV files against JSON Schema definitions using AJV and csv-parse. Automatically detects and repairs type mismatches, missing required columns, and encoding issues with configurable strictness levels.
CSpell Codebase Spell Checking CLI
CSpell is a spell checker built for source code, configuration files, and documentation, with dictionaries and ignore mechanisms that work well in real repositories. It helps agents and teams catch noisy typos before they land in code review, docs, or CI output.
CSP Policy Analyzer
Parses and evaluates Content Security Policy headers using csp-parse and csp-evaluator libraries. Identifies overly permissive directives, missing protections, and generates tightened policy recommendations.
Crush Agentic AI Coding CLI by Charmbracelet
Crush is a terminal-native AI coding agent built by Charmbracelet that connects your code, tools, and workflows to any LLM. It supports multi-model switching mid-session, MCP extensibility, and LSP-enhanced context across every major platform.
Crunchbase Company Intelligence Scraper
Extracts company profiles, funding rounds, and investor data using the Crunchbase Enterprise API v4 with autocomplete, search, and entity lookup endpoints. Builds competitive landscape maps with funding timeline visualizations.
Cronitor CLI for Cron Monitoring and Job Telemetry
CronitorCLI is Cronitor's open-source command-line tool for syncing cron jobs, sending telemetry pings, and wrapping commands with execution monitoring. It fits monitoring-heavy agent runbooks where scheduled jobs, server tasks, and long-running commands need explicit visibility.
Cron Job Manager
The open catalog of AI agent skills — 2,000+ security-scanned skills for Claude Code, Cursor, Codex, and more.
CrewAI Multi-Agent Orchestration Framework
CrewAI is a lean, lightning-fast Python framework for orchestrating role-playing autonomous AI agents. It enables developers to define agents with specific roles, goals, and backstories, then assemble them into crews that collaborate on complex tasks through sequential or paralle
Create, repair, and recalculate spreadsheet workbooks without breaking formulas
Use the Anthropic xlsx skill when an agent needs to create, clean up, or modify .xlsx, .xlsm, .csv, or .tsv files as spreadsheet deliverables, not just inspect tabular data. It pushes the agent toward formula-safe edits, workbook validation, and recalculation instead of hardcoded
Create and repair Word documents with layout-safe DOCX workflows
Use the Anthropic docx skill when an agent needs to produce or repair a real .docx deliverable with headings, tables, numbering, tracked changes, or layout constraints. It frames the work as a document-building workflow with validation and packaging rules, not as a generic docume
Create and debug local-first declarative workflow jobs with Dagu
Use Dagu to define file-backed workflow jobs in YAML, run them locally or across workers, and inspect failures through a lightweight operator surface instead of a heavyweight orchestrator.
