Prepare a GitHub pull request on a local branch by default or in an isolated worktree when explicitly requested, optionally merge the latest base branch, and produce a rigorous review from PR context and actual code changes. Use for local PR checkout, worktree review, parallel review, or concurrent review.
Use when the user asks to commit a worktree branch, rebase it onto the specified target branch, resolve conflicts, then merge the branch from that target checkout. Also use it to directly commit changes that are already on the default target branch. If no target branch is specified, default to the repository remote default branch.
Create staged-only Angular-style commits. Runs `git commit` by default, supports confirmation or preview-only requests, and writes bilingual local-language + separator + English commit messages for non-English users.
Use when the user wants to create any technical diagram - architecture, data flow, flowchart, sequence, agent/memory, or concept map - and export as SVG+PNG. Trigger on: "画图" "帮我画" "生成图" "做个图" "架构图" "流程图" "可视化一下" "出图" "generate diagram" "draw diagram" "visualize" or any system/flow description the user wants illustrated.
Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Use when asked to "simplify code", "clean up code", "refactor for clarity", "improve readability", or review recently modified code for elegance. Focuses on recently modified code unless instructed otherwise.
