Agent Claude Code
Holistic software architecture planner that evaluates tech stacks, designs scalability roadmaps, performs cloud-agnostic cost analysis, reviews existing codebases, and delivers interactive Mermaid diagrams with HTML preview and draw.io export.
Agent Claude Code needs its repo
Generates professional MS Word project documentation with draw.io architecture diagrams and embedded PNG images. Automatically discovers any project's technology stack, architecture, and code structure. Produces Markdown, draw.io diagrams, PNG exports, and .docx output.
Agent Claude Code
Expert prompt engineering and validation system for creating high-quality prompts - Brought to you by microsoft/edge-ai.
Agent Claude Code
A specialized chat mode for analyzing and improving prompts. Every user input is treated as a prompt to be improved. It first provides a detailed analysis of the original prompt within a tag, evaluating it against a systematic framework based on OpenAI's prompt engineering best practices. Following the analysis, it…
Agent Claude Code
Expert assistant for developing Model Context Protocol (MCP) servers in Python.
Agent Claude Code
Custom agent for building Python Notebooks in VS Code that demonstrate Azure and AI features.
Agent Claude Code
Meticulous QA subagent for test planning, bug hunting, edge-case analysis, and implementation verification.
Agent Claude Code
Run a complete quality engineering audit on any codebase. Orchestrates six phases — explore, generate, review, audit, reconcile, verify — each in its own context window for maximum depth. Then runs iteration strategies to find even more bugs. Finds the 35% of real defects that structural code review alone cannot catch.
Agent Claude Code
Deep-scan specialist for React 16/17 class-component codebases targeting React 18.3.1. Finds unsafe lifecycle methods, legacy context, batching vulnerabilities, event delegation assumptions, string refs, and all 18.3.1 deprecation surface. Reads everything, touches nothing. Saves .github/react18-audit.md.
Agent Claude Code
Automatic batching regression specialist. React 18 batches ALL setState calls including those in Promises, setTimeout, and native event handlers - React 16/17 did NOT. Class components with async state chains that assumed immediate intermediate re-renders will produce wrong state. This agent finds every vulnerable…
Agent Claude Code
Class component migration specialist for React 16/17 → 18.3.1. Migrates all three unsafe lifecycle methods with correct semantic replacements (not just UNSAFE prefix). Migrates legacy context to createContext, string refs to React.createRef(), findDOMNode to direct refs, and ReactDOM.render to createRoot. Uses memory…
Agent Claude Code
Master orchestrator for React 16/17 → 18.3.1 migration. Designed for class-component-heavy codebases. Coordinates audit, dependency upgrade, class component surgery, automatic batching fixes, and test verification. Uses memory to gate each phase and resume interrupted sessions. 18.3.1 is the target - it…
Agent Claude Code
Dependency upgrade specialist for React 16/17 → 18.3.1. Pins to 18.3.1 exactly (not 18.x latest). Upgrades RTL to v14, Apollo 3.8+, Emotion 11.10+, react-router v6. Detects and blocks on Enzyme (no React 18 support). Returns GO/NO-GO to commander.
Agent Claude Code
Test suite fixer and verifier for React 16/17 → 18.3.1 migration. Handles RTL v14 async act() changes, automatic batching test regressions, StrictMode double-invoke count updates, and Enzyme → RTL rewrites if Enzyme is present. Loops until zero test failures. Invoked as subagent by react18-commander.
Agent Claude Code
Deep-scan specialist that identifies every React 19 breaking change and deprecated pattern across the entire codebase. Produces a prioritized migration report at .github/react19-audit.md. Reads everything, touches nothing. Invoked as a subagent by react19-commander.
Agent Claude Code
Master orchestrator for React 19 migration. Invokes specialist subagents in sequence - auditor, dep-surgeon, migrator, test-guardian - and gates advancement between steps. Uses memory to track migration state across the pipeline. Zero tolerance for incomplete migrations.
Agent Claude Code
Dependency upgrade specialist. Installs React 19, resolves all peer dependency conflicts, upgrades testing-library, Apollo, and Emotion. Uses memory to log each upgrade step. Returns GO/NO-GO to the commander. Invoked as a subagent by react19-commander.
Agent Claude Code
Source code migration engine. Rewrites every deprecated React pattern to React 19 APIs - forwardRef, defaultProps, ReactDOM.render, legacy context, string refs, useRef(). Uses memory to checkpoint progress per file. Never touches test files. Returns zero-deprecated-pattern confirmation to commander.
Agent Claude Code
Test suite fixer and verification specialist. Migrates all test files to React 19 compatibility and runs the suite until zero failures. Uses memory to track per-file fix progress and failure history. Does not stop until npm test reports 0 failures. Invoked as a subagent by react19-commander.
