Full backlink profile for a domain — referring domains, anchor text distribution, authority distribution, IP and subnet diversity, growth/decay trend, toxic-candidate flagging. Distinct from `seo-backlink-gap` (which is gap-vs-competitor only). Produces a profile health score and reviewable disavow candidate list (never auto-disavow). Use when the user asks "backlink profile", "link profile audit", "anchor distribution", "toxic links", "disavow candidates", or "backlink health".
When structuring code into layers and modules with clear boundaries. Use when the user says "this function does too much," "fat controller," "mixed concerns," "where should this logic go," or "separate the layers." For interface-level design, see solid. For object-level coupling, see law-of-demeter.
Push message notifications to WeChat/App via Server Chan (Fangtang). Use this skill when you need to push execution results, alerts, task completion status, and more to your phone (both Server酱 Turbo SCT and Server酱³ SC3 are supported, automatically identified by the SendKey prefix). Supports titles, Markdown body, and optional parameters such as tags/short/channel.
This skill MUST be used to turn a service design problem into a practical brief, service architecture, touchpoint analysis, or prototype validation plan, including 服務設計、服務流程、接觸點、前台後台、服務實證、顧客體驗、利害關係人、服務概念、服務架構. It SHOULD also be used to improve part of an existing service design or prepare workshop outputs, even when the user does not name a method or workshop.

Use when the user needs to configure Sonilo, wants to sign in or connect their Sonilo account, when Sonilo tools are missing, or when a call fails because no key or credential is available. First checks what already works, and only runs full setup when needed.
Use when creating skill repositories, standardizing or validating skill repo structure, setting up composer/release workflows, configuring split licensing (MIT + CC-BY-SA-4.0), fixing plugin.json / SKILL.md validation or version-parity errors, writing or validating skill evals, selection tests or captured agent evidence, or releasing a skill version (version bump, tagging).
Search Agent Skills in SkillsMP (an index of 1.6M+ public SKILL.md files covering Claude Code / Codex / ChatGPT), filtering by keyword, category, occupation, and language, and specifically dig up obscure Skills that are "well written but unknown". Use when the user says 找个 skill, 有没有现成的 skill, 搜一下 skill, skillsmp, skills 市场, agent skill 搜索, find a skill, search skills, discover skills. Also used to see which Skills already exist in a field and avoid reinventing the wheel. It also covers these colloquial phrasings: 这个功能有没有人做过, 别人写过没, 我想写个做 X 的 skill（动手前先搜）, 挖点冷门好用的, 有没有小众但写得好的, 这领域现在都有啥, 按星数排靠不靠谱, 只要中文的 skill.

Adaptive teaching skill that dynamically adjusts explanation depth to the user's actual level of understanding. Triggered when the user wants to learn something, asks for an explanation suited to their level, or explores a new topic. Trigger words: "教我", "我想学", "解释一下", "我不懂", "怎么理解", "什么是", "帮我理解", "我是新手", "入门", "深入讲讲", "讲简单点", "讲深入一点", "学习". Interview triggers: "来一轮面试", "面试模式", "考考我", "challenge me", "面试". It can also trigger when the user asks a knowledge question — first give a brief answer, then proactively ask whether they want to go deeper. Not for: code debugging, file operations, project management, or pure factual lookups (requests with no learning intent).
Authoritative framework for reviewing any proposed solution (code, config, process, tooling, or architecture decision) before implementation. Covers four core dimensions (effectiveness, side-effects/risks, feasibility, spec compliance) plus five strategic dimensions that catch decision-level failures the core four miss: reversibility calibration (Bezos one-way/two-way doors), failure-mode analysis (FMEA), operability (SRE Production Readiness Review), cost-vs-value (CBAM/WSJF), and team cognitive fit (Team Topologies). Use this skill whenever you need to review, validate, stress-test, or approve a proposed solution, plan, design doc, or approach — before any code is written or change is applied. Triggers — 「审查方案」「方案审查」「评估方案」「方案评估」「review proposal」「方案可行吗」「这个方案靠谱吗」「方案有没有风险」「方案评审」「设计评审」「决策评审」 / solution review, proposal review, design review, decision review, stress-test a plan, validate an approach.

Always invoke before testing a geographic pattern for clustering, hotspots, dependence, or explanatory regression, even when aggregation or ordinary OLS is proposed as routine. Covers Moran's I, LISA, Getis-Ord Gi*, weights, MAUP and scale sensitivity for areas/grids, residual dependence, and spatial lag/error/GWR/MGWR models. Use ML standards for predictive evaluation and geostatistics for continuous surfaces from sparse samples.
Provides comprehensive guidance for Spring Data JPA including repositories, entity management, query methods, and database operations. Use when the user asks about Spring Data JPA, needs to work with JPA repositories, implement data access layers, or configure JPA in Spring
Production-ready reinforcement learning algorithms (PPO, SAC, DQN, TD3, DDPG, A2C) with scikit-learn-like API. Use for standard RL experiments, quick prototyping, and well-documented algorithm implementations. Best for single-agent RL with Gymnasium environments. For high-performance parallel training, multi-agent systems, or custom vectorized environments, use pufferlib instead.
This skill should be used when user asks to "use supabase CLI", "supabase init", "supabase start", "run migrations", "deploy edge functions", "manage Supabase project", or works with the supabase command-line tool for local development and project management.
Guides collaborative discovery of hidden symmetries in ML data through structured domain analysis, coordinate system examination, transformation testing, and physical constraint identification. No group theory knowledge required. Use when ML engineers need to identify symmetries in their data, when user mentions data symmetry, invariance discovery, what transformations matter, or needs help recognizing patterns their model should respect.
