Create SVG diagrams with professional PPT-quality layout, clear connections, and no overlapping elements. Use when creating flowcharts, architecture diagrams, sequence diagrams, concept diagrams, or charts as SVG, or when fixing layout or styling issues in existing SVGs.
Perform systematic reviews of code and documents across files, folders, diffs, commits, pull requests, or branch comparisons. Evaluates correctness, security, performance, maintainability, and structural quality. Provides prioritized, actionable feedback without making changes. Use when users request reviews, feedback, or quality assessments on code or documents.
Clarify feature requirements and generate detailed, step-by-step TDD-based implementation plans for new functionality. Introduces new observable behavior that does not exist today. Use when users request new features, enhancements, or functionality additions, or when users ask exploratory questions about whether a feature is possible (e.g., "is it possible to...", "can we add...", "would it be feasible to...") that imply a desire to implement new behavior. This skill produces a plan but does not execute changes—pair with plan-executor for implementation.
Review SKILL.md files for correct structure, section-purpose compliance, and absence of duplication. Evaluates whether knowledge, capabilities, rules, and examples sections each serve their intended purpose. Use when users request feedback, a quality assessment, or want to improve, fix, or ensure a copilot skill file triggers correctly.
Synchronize documentation with code changes across README, architecture docs, API docs, and requirements. Assesses documentation impact and provides focused updates, migration guides, and examples. Use after implementing bug fixes, features, or refactors that affect documented behavior, APIs, or workflows, or when documentation is stale, inconsistent, or missing, or when tests reveal discrepancies between documented and actual behavior, or when configuration files affecting developer setup are modified.
Develop WeChat Miniprogram features following platform conventions and best practices. Use this skill when adding pages, components, or features to a WeChat Miniprogram project, debugging platform-specific runtime errors, or configuring routing, TabBar, or subpackage structure.
Execute structured plans step-by-step with progress tracking, validation checkpoints, and error recovery. Works with plans from bug-fix-planner, feature-implementation-planner, or refactor-planner. Runs tests, validates changes, and handles failures systematically. Use after generating an implementation, refactor, or bug-fix plan that needs execution.
Investigate codebases to answer questions about functionality, implementation, design decisions, and architecture. Analyzes code structure, traces control/data flow, and examines dependencies to provide comprehensive answers. Use when users ask "what", "how", "why", "where", or "when" questions about existing code. Does not modify code.
