Devcontainer Setup

Detect and untangle circular dependencies. Runs madge/skott (TS), pycycle (Py), or compiler-only checks (Go/Rust). Auto-fixes leaf-extractable cycles; reports core cycles for human review. Use when the user asks to find circular imports, fix dependency cycles, or untangle module graph. Example queries — "find circular imports", "fix dependency cycles", "untangle our module graph", "why is madge complaining".

Remove pointless try/catch blocks and defensive guards that hide errors or add no value. Preserves catches at true system boundaries (HTTP handlers, CLI entry, message consumers). Use when the user asks to remove try/catch, fix error hiding, clean up defensive code, or stop swallowing errors. Example queries — "remove pointless try/catch", "we're swallowing errors", "stop hiding bugs in catch blocks", "clean up the defensive code".

交互式调试源代码 — 设置断点、逐行单步执行、检查实时变量状态、针对正在运行的程序评估表达式，以及导航调用堆栈以追溯根本原因。当程序崩溃、引发意外异常、产生错误输出、需要理解执行如何达到某个状态，或打印语句调试不足以揭示问题时使用。

Create general-purpose Dockerfiles for Node.js, Python, Go, Rust, and Java projects. Covers base image selection, dependency installation, user permissions, COPY patterns, ENTRYPOINT vs CMD, and .dockerignore. Use when containerizing an application for the first time, creating a consistent build/runtime environment, preparing an app for cloud deployment or Docker Compose, or when no existing Dockerfile is present in the project.

Worktree-first dev environment manager for issues, PRs, and features with optional tmux sessions

Baseline cross-project coding conventions for naming, readability, immutability, and code-quality review. Use detailed frontend or backend skills for framework-specific patterns.
