Coding & Dev Tools

Builds web APIs and full-stack apps with Hono, covering routing, middleware, validation, RPC clients, and deployment across edge runtimes.

Keeps AI coding agents tightly scoped by enforcing minimal changes, simplest solutions, and asking before expanding scope or adding dependencies.

Manages persistent terminal sessions, windows, and panes with tmux, including scripting multi-pane layouts and automating commands from shell scripts.

Provides C programming guidance for systems programming, covering memory management, pointer arithmetic, POSIX compliance, and debugging with valgrind and gdb.

Provides guidance and patterns for using a vector-powered CLI for semantic file search with Claude/Codex skills.

Guides incremental code improvements, error-proofing through types and validation, and standardization for higher quality and fewer defects.

Create interactive, publication-quality visualizations with 40+ chart types, hover, zoom, pan, and web embedding. Choose between Plotly Express and Graph Objects for dashboards, exploratory analysis, and presentations.

Compare AI-generated UI variants in a running local app, then keep the chosen option and remove temporary code.

Provides expert guidance on modern Angular development, covering Signals, Standalone Components, Zoneless applications, SSR/Hydration, and reactive patterns.

Analyzes core dumps and live processes with GDB, correlating source code with runtime state to diagnose crashes, deadlocks, and memory issues in C/C++ programs.

Design GraphQL schemas, resolvers, and DataLoader patterns, and integrate clients with Apollo or urql.

Enforces an algorithm-first discipline: state Big-O, data structure, and algorithm family before writing loops, queries, or recursion, catching O(n^2), N+1, and brute-force defaults.

Build cross-platform AI chat interfaces with Makepad using MolyKit, covering async patterns, chat widgets, and OpenAI-compatible SSE streaming.

Write idiomatic, high-performance PHP using generators, iterators, SPL data structures, and modern OOP features.

Scaffolds a new mobile-first page using StyleSeed Toss layout patterns, section rhythm, and existing shell components.

Answer repository questions grounded entirely in source code evidence, with inline citations and key file tables.

Provides a structured debugging workflow for diagnosing errors, test failures, and unexpected behavior, including root cause analysis and fix verification.

Covers Firebase Authentication, Firestore, Realtime Database, Cloud Functions, Storage, and Hosting, with patterns for security rules, data modeling, and real-time listeners.

Build clean async pipelines with fp-ts TaskEither, replacing nested try/catch blocks with composable error handling and real API examples.

Provides expert guidance on modern Java 21+ development, covering virtual threads, pattern matching, Spring Boot 3.x, GraalVM, and cloud-native enterprise patterns.

Architects, reviews, and scales backend systems with structured blueprints, trade-off analysis, and audit reports.

Provides guidance and best practices for writing idiomatic Ruby code, covering metaprogramming, Rails patterns, gem development, performance optimization, and testing with RSpec and Minitest.

Provides expert guidance on modern Rust 1.75+ development, covering async patterns, advanced type system features, and production-ready systems programming.

Iterates through pending development plans in .cursor/plans, implementing tasks, running self-tests, reviewing code, committing locally, and moving completed plans to docs/plans/done.

Enter explore mode to think through ideas, investigate problems, and clarify requirements before implementation, with optional OpenSpec artifact creation.

Implements tasks from an OpenSpec change, tracking progress and pausing for clarification when needed.

Build fast, type-safe web APIs and full-stack apps that run on Cloudflare Workers, Deno, Bun, Node.js, and other WinterCG-compatible runtimes.

Manages tmux sessions, windows, and panes for persistent terminal work and scriptable multi-pane layouts.

Converts human-written CLAUDE.md files into a structured-label format that AI models follow more reliably while using fewer tokens.

Provides comprehensive guidance for performing symbolic algebra, calculus, linear algebra, equation solving, physics calculations, and code generation using the SymPy Python library.

Provides guidance and patterns for using a vector-powered CLI for semantic file search with a Claude/Codex skill.

Guides incremental code improvements, error-proofing through types and validation, and standardization for higher code quality.

Creates interactive, publication-quality visualizations in Python with 40+ chart types, including hover, zoom, pan, and web-embeddable output.

Build modern Angular v20+ apps using Signals, Standalone Components, Zoneless change detection, SSR/Hydration, and reactive patterns.

Write idiomatic C++ code with modern features, RAII, smart pointers, and STL algorithms. Handles templates, move semantics, and performance optimization.

Analyze core dumps, debug live processes, and investigate crashes, deadlocks, or memory issues in C/C++ programs using GDB with intelligent source code correlation.
