Use when adding or fixing anything the user drags, flicks or swipes, when an animation needs to start from the finger's speed, when something should rubber band at an edge, or when a gesture feels stuck, jumpy or janky on touch.
Design, implement, repair, or review product analytics in Flutter using event contracts, identity, consent, funnels, attribution, experiment exposure, delivery semantics, and backend verification. Use for measuring user behavior and business outcomes; not for operational logs, crash reporting, profiling, or general UI tracking
Design interfaces that support sustained focus and reduce distractions. Use when designing for users with ADHD, attention difficulties, anxiety, or any context where focus matters — dashboards, reading experiences, task flows, forms, learning interfaces. Triggers on: focus, distraction, ADHD, attention, too busy, cluttered, visual noise, autoplay, notifications, pop-ups, interruptions.

Load when: constructing a ghidra-agent-cli command, interpreting its output, resolving a flag or artifact path question, or debugging CLI behavior. Do not load for P0–P4 workflow sequencing — use the headless-ghidra skill family instead.
Automatically stage, commit, and push with Git. Use this skill when the user asks to commit code, push code, commit, push, commit and push, auto-commit, stage-commit-push, or any operation involving git commit/push. Also applies to colloquial phrasings such as "提交一下", "推一下代码", "帮我提交", "push 上去", "仅提交", or "只 commit".

Trigger on "Search Console," "GSC," "what keywords am I getting traffic for," "what queries," "impressions," "click-through rate," "indexing issues," "is my page indexed," or "organic performance."
Creates a minimal line-graph animation for a reel. A smooth black line draws itself on white (or white on black) while one large number counts up alongside it, then settles on the final value. Use when the user runs /graph or asks for a growth chart, a “0 to 100K” number animation, or an animated stat.
Invoke the locally installed Grok Build CLI from Codex and return Grok's response. Use whenever the user asks Codex to call, consult, run, or delegate a prompt to Grok or Grok Build, including Grok web/X searches and agentic Grok tasks. This Skill covers only the invocation mechanism, process monitoring, and response capture; it does not prescribe the task itself.

Use when writing .ets component files, using ArkUI decorators like @Component/@State/@Prop/@Link, building layouts with Column/Row/Stack/List, managing HarmonyOS app resources with $r(), or handling component lifecycle and accessibility on HarmonyOS.
Provides practical frameworks for fast decision-making through mental shortcuts (heuristics) and systematic error prevention through structured checklists. Guides through designing effective heuristics, creating checklists for complex procedures, and recognizing when shortcuts lead to biases. Use when making decisions under time pressure or uncertainty, preventing errors in complex procedures, designing decision rules or checklists, simplifying complex choices, or when user mentions heuristics, rules of thumb, mental models, checklists, error prevention, cognitive biases, satisficing, or standard operating procedures.
Review a submitted PR like a human reviewer: read the committed diff and related call sites, then leave substantive findings (security, logic, correctness, dangerous practices) as GitHub inline comments on the exact lines. Not for lint/pre-commit noise or merge gates (use pre-merge-gate). Not for replying to threads (use heyeddi-pr-respond).
Product leadership: user stories, acceptance criteria, backlog, holistic reviews. Verifies the product works and is useful; delegates UX flow, design critique, visual contrast, and engineering audits; synthesizes plans and change recommendations. Use after @heyeddi-intake, before ship, or when the user asks for PM review, user stories, acceptance criteria, or "is this feature good enough?"
Hybrid adaptive memory: Cheatsheet (positive patterns pre-generation) and Immune (negative patterns post-generation) with Hot/Cold tiered auto-learning. Triggers on: "scan for errors", "immune scan", "check output quality", "antibody scan". NOT for PR review (use pr-review) or repo audits (use repo-sentinel).

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
