Comprehensive Vue 3 frontend development skill. Use when developing Vue 3 applications, components, or composables. Covers: (1) Creating new Vue 3 projects and components, (2) Vue 2 to Vue 3 migration, (3) Code review and optimization, (4) Composition API implementation, (5) Best practices and common patterns, (6) TypeScript integration, (7) State management with Pinia, (8) Performance optimization. Includes component templates, composable examples, migration guides, and best practices documentation.

Generate descriptive commit messages by analyzing git diffs. Use when the user asks for help writing commit messages or reviewing staged changes.

【WHEN】当用户要新增/修改/评审“治理层文档”（README.md、CLAUDE.md、以及用户显式指定的其他治理层文档）时启用； 【WHEN】当输出提案 vN.md、落地修改治理层文档、或产出 vN-review.md 时启用。 【WHEN NOT】不用于业务功能开发、不用于代码实现细节、不用于非治理层文档（如普通开发笔记/模块设计/接口文档）。

Write meaningful code comments that explain WHY rather than WHAT, focusing on business logic, non-obvious solutions, workarounds, and complex algorithms while keeping code self-documenting. Use this skill when adding comments to explain rationale, documenting complex business logic, explaining workarounds or temporary solutions, describing performance optimizations, writing function documentation (JSDoc, docstrings, XML docs), or reviewing code for appropriate commenting. Apply when working on any code file that contains logic requiring explanation, public API functions, complex algorithms, security-critical code, or architectural decisions. This skill ensures comments explain rationale not implementation (WHY not WHAT), self-documenting code through clear naming (refactor unclear code instead of commenting), concise and evergreen comments (no who/when dated comments - Git tracks this), links to external resources for context, proper function documentation format (JSDoc for TS/JS, docstrings for Python, XML docs for .NET), no TODO/FIXME in committed code (use issue tracking system instead and reference ticket), and deletion of dead commented-out code (Git history preserves it).

Validate markdown documentation against meta-agentic best practices. Use when validating skills, commands, checking broken links, validating frontmatter, auditing documentation structure, or running compliance checks.

Work with MongoDB (document database, BSON documents, aggregation pipelines, Atlas cloud) and PostgreSQL (relational database, SQL queries, psql CLI, pgAdmin). Use when designing database schemas, writing queries and aggregations, optimizing indexes for performance, performing database migrations, configuring replication and sharding, implementing backup and restore strategies, managing database users and permissions, analyzing query performance, or administering production databases.

Use when user wants to add a new sensor to the Enviro+ monitoring system, or asks to monitor a new data point. Guides through importing libraries, initialization, reading sensor values, publishing to Adafruit IO and Home Assistant, updating documentation, testing, and rate limit verification.

Use this skill when you need to structure data in `srs/data` for the Next.js app

Manage hierarchical project plans in SQLite. Tree-based structure with phases and tasks. Multiple output formats (text, JSON, XML, markdown).

Guide users through structured feature specification creation from idea to complete spec. Use when user wants to create a feature specification, product requirements document (PRD), technical spec for a feature, or similar structured feature planning documentation. This workflow helps users efficiently gather context, explore the codebase, define requirements, draft technical approach, and save the result to JIRA or Confluence. Trigger when user mentions "create a spec", "spec out", "write a PRD", "feature specification", or similar feature planning tasks.

Detect document source type (Zoom, Slack, JIRA, Confluence, email, meeting notes) from content patterns. Use when processing raw documents during intake or when identifying document types.

Use when writing UnoCSS with presetOnmax workflow - covers attribute mode patterns, fluid spacing (f- prefix), scale-to-pixel (1px base), custom variants (hocus, reka-*, data-state), nimiq-css design system (nq-* utilities), and Reka UI integration. Apply when editing .vue files with UnoCSS attributes or configuring uno.config.ts.

DuckDB data lakehouse development with Dagster orchestration and Apache Iceberg integration for floe-platform. Use when: (1) Building data pipelines with DuckDB as compute engine, (2) Configuring dbt-duckdb with Polaris plugin, (3) Reading/writing Iceberg tables via Polaris catalog, (4) Creating Dagster assets with DuckDB, (5) Designing catalog-first lakehouse architecture, (6) Connecting to REST catalogs with inline credentials.

Load coding conventions and style guidelines when writing or reviewing code. Ensures consistency with project standards.

Manage project planning, documentation, and ticket coordination. Use this skill for: (1) Project planning and roadmap management, (2) Creating and coordinating tickets (T0000N), (3) Managing docs/ directory structure and CRUD operations, (4) Post-ticket completion tasks (export tests, update planning docs).

Apply 37signals/DHH Rails conventions when writing Ruby on Rails code. Use when building Rails applications, reviewing Rails code, or making architectural decisions. Covers various aspects of Rails application architecture, design and dependencies.

Takes the dual of a linear program (LP). Use when the user provides an LP in LaTeX or markdown and wants its dual, or asks about LP duality transformations.

This skill provides prescriptive guidance for writing modern CSS layouts using intrinsic design principles, container queries, and fluid responsive techniques. When implementing CSS layouts, always consult this document first.

Install pre-commit hooks to automatically lint markdown files before commits

Use this skill when the user wants to create, write, or install shell scripts. Prefers Fish shell, handles writing fish/bash/zsh/sh scripts and installing them to ~/bin/scripts with proper permissions and git workflow. Activates when user mentions "shell script", "bash script", "fish script", "install script", or wants to create command-line utilities.
