I am Chen Xiaoqun, a top trader of the new generation of hot money in the A-share market, practicing a short-term leading-stock strategy that started from 300,000. Sentiment cycle × leading-stock conviction × iron discipline: only trade the main line, only trade leaders, no junk stocks. Trigger words: "陈小群", "小群", "用陈小群的方式", "群总". Suitable scenarios: A-share short-term trading analysis, leading-stock judgment, sentiment-cycle assessment, position-management reference, and understanding hot-money thinking.
Verify citations and references in scientific documents to detect hallucinated or invalid sources. Extracts DOIs, URLs, arXiv IDs, PubMed IDs, and ISBNs from Markdown, LaTeX, org-mode, and plain text, then validates them using API lookups and web fetches. Use this skill when: - Reviewing AI-generated content for citation accuracy - Validating references in papers, reports, or documentation - Checking if DOIs/URLs resolve to actual papers - Auditing a document for broken or fake citations
Reason about clinical data terminology standards — MedDRA hierarchy (LLT→PT→HLT→HLGT→SOC), ICD-10 code structure and grouping, SNOMED CT concept model, LOINC panel relationships, and mapping decisions between systems. Use when the user asks to code adverse events, map diagnoses to ICD-10, choose a coding granularity level, group AEs by SOC or PT, interpret SNOMED CT relationships, select LOINC codes for lab panels, convert between terminology systems, or decide when to aggregate at HLT vs PT level. Triggers include "MedDRA coding", "ICD-10 grouping", "SNOMED CT", "LOINC panel", "adverse event coding", "terminology mapping", "SOC table", "preferred term", "code hierarchy", "clinical coding", "AE frequency table", "diagnosis grouping", "lab code selection", "cross-walk between terminologies".
Diagnose and guide Contentstack Live Preview and Visual Builder implementations. Trace preview context, identify the broken contract, and recommend the smallest correct fix across CSR, SSR, SSG, middleware/BFF, and tagging flows.
Advise developers on using Contentstack Variants and Personalize for audience-targeted content. Explain when to use variants versus separate entries, how variant groups work, and how to integrate Personalize with the CMS. Use when developers ask about content personalization, A/B testing, audience segmentation, variant creation, or integrating Personalize with the CMS.
Analyze and improve a software project's module boundaries, dependency direction, file organization, code duplication, oversized modules, and unnecessary indirection.

Use this skill to analyze what a competitor publishes, which content earns estimated traffic, the SEO plays they use, and where gaps exist. Trigger it before creating or refreshing a content strategy or when investigating a competitor's organic content performance.
Regulatory compliance auditing across GDPR, HIPAA, PCI DSS, SOC 2, and ISO frameworks with automated evidence collection and gap analysis. Use when conducting compliance assessments, preparing for certifications, or implementing regulatory controls.
Use when writing, changing or reviewing code that touches the house contract for Jetpack Compose and Compose Multiplatform apps: module graph, MVI/BaseViewModel, error tiers, state ownership, naming, Koin DI, Navigation 3 and coroutines. The compose skill is the entry point. Do NOT use for Gradle-only work (compose-project), new screens (compose-feature), composable-only work (compose-ui), repositories or persistence (compose-data), or expect/actual splits (compose-platform).
Owns project and build-level work for Compose and Compose Multiplatform apps: bootstrapping a new project, adopting the kit in an existing project, adding or extracting a module, convention plugins in build-logic, the version catalog, and CI plus agent hooks. Use when starting a Compose Multiplatform app, adding a module, or editing settings.gradle.kts, build.gradle.kts, build-logic, libs.versions.toml, or packaging. Do NOT use for routing and architecture choices (compose-architecture), feature code (compose-feature), repositories and persistence (compose-data), composables or resources (compose-ui), or commonMain vs platform code (compose-platform).
Define, compare, and audit constrained optimization decisions with explicit variables, units, hard and soft constraints, feasibility, Pareto tradeoffs, and honest solver evidence. Do not use for statistical modeling or ML fitting, which belong to data-scientist or ml-engineering, or for operating a named solver.
Audits a blog post draft or page copy for content-level SEO: search intent fit, focus keyphrase placement, E-E-A-T signals (experience, expertise, authoritativeness, trustworthiness), helpfulness and originality, content freshness, and internal linking. Use when the user asks "will this rank", "SEO check this post", "content SEO audit", or "optimize this post for search" — or proactively after a readability pass on a post that's meant to rank. For how the prose reads, use the `readability-check` skill; for titles and meta descriptions, use `metadata-check`; for site-wide technical SEO (sitemaps, structured data, canonicals), use `astro-seo` or `static-seo`.
Copilot left 14 review comments on your PR — half are nits. Hours of fix → reply → resolve → re-request, and each round lands MORE comments. This skill runs loop engineering: auto-triggers Copilot Code Review via GraphQL (no @copilot mention), triages every open thread (Copilot, humans, advanced-security) with a fix / decline / escalate rubric, dispatches parallel fix sub-agents that obey the repo build/test/lint conventions, commits per iteration, replies+resolves citing the pushed SHA, then re-triggers until HEAD is reviewed with zero threads awaiting the agent's reply (remaining open threads are explicit hand-offs to the human — escalated declines, design tradeoffs). You merge a clean PR; the bot runs it. Trigger phrases: "address copilot comments", "run a copilot review loop", "fix this PR", "iterate on copilot feedback". Repo-agnostic, gh CLI + PowerShell. Full autopilot needs repo Triage/Write; external PR authors get single-iteration mode plus manual re-trigger (UI 🔄 or substantive-commit push).
Craft CMS 5 content modeling — sections, entry types, fields, Matrix, relations, project config, and content architecture strategy. Covers choosing section types, designing entry types and field layouts, selecting field types, configuring Matrix and nested entries, relations and eager loading, and multi-site propagation.

CSS authoring guidance emphasizing web standards, accessibility, and performance. Use when writing, reviewing, or refactoring CSS. Provides patterns, snippets, and conventions that prioritize native CSS over frameworks, semantic structure, and maintainable code. Refer to references/patterns.md for specific patterns and snippets.
Authoritative guide for Dart SDK language specifications, syntax availability, minimum SDK constraints (minSdk), and version changelogs from Dart 1.x through Dart 3.x. Use this skill whenever authoring or refactoring Dart code, inspecting pubspec.yaml sdk constraints, writing control flow (switch statements, pattern matching, switch expressions), implementing class constructors (primary constructors, parameter shorthands), using macros/augmentations, verifying language feature availability against the project's minSdk, or modernizing legacy codebases.
Guides multimodal media authentication and deepfake forensics using provenance checks, metadata review, PRNU/noise analysis, temporal consistency, semantic forensics, and evidence reporting.

Use when replacing traditional VPN servers with an identity-authenticated mesh network or enforcing granular per-device access control lists.
The universal principles behind strong visual design — across logos, brand identity, collateral, and web. Use at the start of any design work, when a design feels off but you can't name why, when judging whether a piece earns its choices, or when a brand needs to flex without breaking. Other design skills inherit these principles.
Writes and tunes Falco rule syntax for container escape detection - conditions, macros, lists, priorities, and output fields - covering host filesystem mounts, sensitive host path access, kernel module loading, and privileged capability abuse, including how to drive down false positives. Use when authoring or tuning a specific Falco rule for breakout behaviour, or triaging a noisy escape-related Falco alert. Keywords: Falco rule, macro, list, condition, priority, falco_rules.local.yaml, tuning, false positive. Do not use for deploying and operating Falco itself - use detecting-container-runtime-threats-with-falco; for tool-agnostic escape signals use detecting-container-escape-attempts.
Create excellent technical documentation with Mermaid diagrams. Use when documenting code architecture, API flows, database schemas, state machines, system design, or any technical concept that benefits from visual diagrams. Also use when asked to explain code, create documentation, write README files, or document how systems work.
ALWAYS invoke for any task involving docstrings, JSDoc/TSDoc, or REST API documentation — even when the request seems handleable without it. Enforces Microsoft contract-first conventions and a bare-minimum rule that Claude won't apply by default: never restate the signature, drop @param/@returns that only echo names and types, always document @throws, and document data shapes as WHAT not WHY. Covers Python docstring styles (Google/NumPy/Sphinx), TSDoc tags and @inheritDoc, and API doc patterns for NestJS/Express/FastAPI/Django. Trigger on: adding or auditing docstrings, redundant or missing tags, deleting comment rot, or producing a documentation-health report. Do not skip for documentation tasks — consistent conventions are the whole point.
Use when the user needs Word document generation, template filling, formatting, mail merge, or DOCX manipulation using python-docx or docxtpl. Trigger conditions: generate Word documents programmatically, fill document templates with data, apply formatting (headings, tables, images, headers/footers), perform mail merge operations, convert DOCX to PDF, manage document styles.
Toolkit for comprehensive document reading, editing, and creation with visual quality control. Use to work with Word documents (.docx files) for: (1) Reading or extracting content from existing DOCX files, (2) Creating new Word documents with professional formatting, (3) Editing documents requiring precise typography and layout, or any other DOCX reading or generation tasks.
Douyin short-video growth assistant for content creators, operators, brands, and e-commerce, used when the user provides Douyin content links; it helps generate sentiment and public-opinion assessments, user profiles and intent signals, operating suggestions, and reply suggestions based on the input material.
Use when landing a stack of dependent GitHub PRs (A ← B ← C, where each bases on the one below) onto master, merging a PR whose base is another open PR's branch, or whenever a request mentions "stacked PRs", "PR stack", "dependent PRs", or merging several related PRs in sequence. Requires every same-repository dependency chain to use GitHub's official stacked-PR feature before landing so GitHub owns stack-wide rules, CI, ordering, retargeting, and merge state.
This skill retrieves upcoming earnings announcements for US stocks using the Financial Modeling Prep (FMP) API. Use this when the user requests earnings calendar data, wants to know which companies are reporting earnings in the upcoming week, or needs a weekly earnings review. The skill focuses on mid-cap and above companies (over $2B market cap) that have significant market impact, organizing the data by date and timing in a clean markdown table format. Supports multiple environments (CLI, Desktop, Web) with flexible API key management.
CodeStable is an AI coding workflow for serious software engineering that keeps humans in the loop. Rather than centering on Agent orchestration, it organizes requirements, architecture, features, issues, and historical decisions to make development driven by Codex and Claude controllable, traceable, and continuously evolvable.
Generate and prioritize US equity long-side edge research tickets from EOD observations, then export pipeline-ready candidate specs for trade-strategy-pipeline Phase I. Use when users ask to turn hypotheses/anomalies into reproducible research tickets, convert validated ideas into `strategy.yaml` + `metadata.json`, or preflight-check interface compatibility (`edge-finder-candidate/v1`) before running pipeline backtests.
A brand product-launch email — masthead with wordmark, hero image block, headline lockup with skewed-italic accent, body copy, primary CTA, and a specifications grid. Pure HTML email layout (centered single column, table fallback). Use when the brief asks for an "email", "newsletter blast", "MJML", "product launch email", or "email template".
A method for having an unbiased executor run agent-facing text instructions (skill / slash command / task prompt / CLAUDE.md section / code generation prompt) and evaluating them from both sides (the executor's self-report + instruction-side metrics) to improve iteratively. Repeat until improvements plateau. Use right after creating or heavily revising a prompt or skill, or when you want to attribute an agent's unexpected behavior to ambiguity on the instruction side.
