BLOG: https://juntz-g1thub.github.io/#post=coding-skills-dev REPO: https://github.com/juntz-g1thub/CodingSkills.gitBackground Recently I ve been experimenting with vibe coding. I m using OpenCode as my development tool. When developing TUI programs, AI-assisted code modification proved extremely difficult — every small bug fix required repeated manual testing, and feeding those results back to the agent was cumbersome. Especially for TUI-level feedback, I d either take screenshots manually or type prompts. At one point, I nearly gave up on AI-assisted development.Motivated by this, I started researching MCP tools. To help agents better utilize these MCP tools, I developed a set of skills combining one or more of them. These skills have been packaged and published to npm.Released Skills 1. agc-debug — TUI Program Debugging Workflow Problem Solved When developing TUI (Terminal User Interface) programs, AI code changes require repeated manual testing. TUI-level feedback is particularly painful — either manual screenshots or typing prompts, resulting in low efficiency.Using the tui-mcp MCP server:launch - Start TUI program screenshot - Capture PNG snapshot snapshot - Capture text snapshot send_keys/send_text - Send keyboard/text input wait_for_text/wait_for_idle - Wait for pattern or terminal idle resize - Resize terminal to test responsive layouts2. agc-explore — CodeGraph-First Exploration Problem Solved When subagents explore code, they often nest grep/read calls repeatedly, resulting in low efficiency. CodeGraph can return in one call what would take dozens of grep+read iterations.3. agc-refactor — Complex Refactoring Workflow Problem Solved Complex design refactoring requires multi-branch reasoning, iterative verification, and visual snapshot comparison. Regular refactoring often leaves you wondering did I get this right? Architecture CodeGraph → Yggdrasil MCP (multi-branch reasoning + session persistence) → TUIdbug (visual verification) ↓ Shell Scripts (state management) ↓ Git Worktree (on-demand isolation) Core Scripts Script Purpose check-mcp-config.sh Check and install required MCP configurations refactor-state.sh Manage refactor session state screenshot-manager.sh Screenshot capture, comparison, archival yggdrasil-helper.sh Yggdrasil session management Dependencies MCP servers: yggdrasil-mcp, tui-mcp, codegraph Sub-skills: using-git-worktrees, systematic-debugging 4. agc-docs — Project Documentation Standards Problem Solved Generic documentation standards don t match actual project needs. Every time you write docs, you have to纠结 format, naming, and content requirements.Core Approach Instead of applying generic rules:Interview user to understand project context Generate project-specific docs/DOC-SPEC.md Enforce project standards throughout development lifecycle Initialization Questionnaire Question Options Project type Application / Library SDK / Infrastructure / Mixed Team size Solo / Small team (2-10) / Medium/Large team (10+) Doc types README, CHANGELOG, API, ADR, User Guide... Special requirements Naming conventions, formatting preferences, tool requirements... Trigger Rules The following operations automatically check DOC-SPEC:Creating/modifying .md files in docs/ Creating/modifying project root .md files Version releases PR creation Template Library# Install npm install @juntz/coding-skills
