Skills

Searches, reserves, inspects, and cancels SRT tickets in Korea using the `SRTrain` Python library with explicit `Adult`/`SeatType` passenger and seat models. Resolves `KSKILL_SRT_ID`/`KSKILL_SRT_PASSWORD` from env vars or `~/.config/k-skill/secrets.env`, summarizes candidate trains before any reservation, and intentionally stops short of payment automation.

Build HTML emails with React components using the React Email library — scaffold via `npx create-email@latest`, run a preview dev server on localhost:3000, and render templates that work across major email clients. Use for welcome emails, password resets, notifications, order confirmations, newsletters, transactional flows, and the embeddable visual email editor.

Reusable weighted graph-ranking engine for warm-intro discovery across X and LinkedIn networks, computing bridge scores `B(m)` with hop-decay `λ`, second-order expansion via `α`, and engagement adjustment `β`. Outputs tiered recommendations: warm intro asks, conditional bridge paths, and graph gaps requiring direct outreach.

Official Brave Search API skills for AI coding agents supporting 8 specialized focus modes (general, coding, news, academic, shopping, social, geo, location) with AI-powered answers and custom ranking via Goggles.

A skill for automating ClickUp workspace management including task creation, workflow automation with triggers and actions, time tracking, goal tracking, and sprint management across the full workspace hierarchy.

AI-powered UX design assistant that helps create user interfaces and improve user experience.

Drives `kakaocli` on macOS to read KakaoTalk chat lists, search messages, and send replies on top of the local KakaoTalk Mac database and macOS accessibility automation (no official Kakao API). Walks through the safety flow — Full Disk Access + Accessibility permissions, `--me`/`--dry-run` testing, mandatory user confirmation before any non-self send.

Provides LibAFL patterns for building custom fuzzers in Rust with coverage-guided feedback, hybrid fuzzing, and multi-architecture support

Tests cryptographic implementations against Google Wycheproof test vectors to identify weaknesses in crypto libraries and protocols

A Claude skill for managing Facebook and Instagram advertising campaigns on the Meta platform, including ad creation and performance optimization.

Sort ECC skills, commands, rules, hooks, and extras into DAILY (always load) vs LIBRARY (keep searchable) buckets for a specific repo by running parallel review passes backed by concrete grep evidence — file extensions, `package.json`/`pyproject.toml`/`Cargo.toml`, CI configs, imports — instead of opinion. Produces an evidence table, install plan, verification report, and optional `skill-library` router so each project loads only what its real stack uses.

A skill that provides Tavily AI search API integration for AI agents, enabling optimized web search directly from conversations using a simple script with environment variable configuration.

Persona skill distilled by 女娲 — encodes Tong Jincheng (童锦程, the "deep-emotion ancestor")'s cognitive frameworks (吸引力 > 讨好, 给台阶, 人性不可考验, 炫耀即暴露不安全感, 成功前后是两个世界) and 9 decision heuristics into a runnable Claude Code skill, grounded in ~200,000 characters of first-hand video transcripts (livestream compilations + dating vlogs) for relationship, dating, and personal-growth analysis.

Thin HIPAA entrypoint that overlays BAA, PHI, covered-entity, minimum-necessary, and audit-trail decision gates on top of `healthcare-phi-compliance` (implementation) and `healthcare-reviewer` (review). Blocks PHI from logs/analytics/crash reports/LLM prompts/URLs and treats third-party SaaS, observability, support tooling, and LLM providers as blocked-by-default until BAA status and data boundaries are proven.

C# and .NET testing patterns built on xUnit, FluentAssertions, NSubstitute/Moq for mocking, `WebApplicationFactory` for ASP.NET Core integration tests, and Testcontainers for real PostgreSQL infrastructure. Covers Arrange-Act-Assert, `[Theory]` parameterized tests with `MemberData`, test data builders, and common anti-patterns to avoid.

Academic search skill from a Shanghai Jiao Tong University medical AI research group, providing academic paper search and literature retrieval capabilities for AI research agents.

Generate [CodeTour](https://github.com/microsoft/codetour) `.tour` JSON files (saved to `.tours/<persona>-<focus>.tour`) for onboarding, architecture, PR, RCA, and security-review walkthroughs with real file/line anchors that open directly in the CodeTour VS Code extension. Picks persona and step count from the request shape (new-joiner, vibecoder, architect, pr-reviewer, etc.), verifies every anchor exists, and writes steps in a Situation/Mechanism/Implication/Gotcha format.

An official ClickHouse agent skill that teaches AI agents best practices for ClickHouse Cloud deployment, covering schema design, query optimization, and data ingestion patterns across 28 prioritized rules.

Automates Obsidian knowledge management workflows including note creation with daily/meeting templates, smart auto-linking with backlink suggestions, Dataview queries for task and project dashboards, and Zettelkasten-style note organization.

A collection of 65 Claude Code skills and 9 workflows with progressive disclosure, covering full-stack development including context engineering and Atlassian integration.

A skill from OpenAI's Agent Skills repository that packages reusable instructions, scripts, and resources for AI agents to perform specific tasks in a repeatable way, designed for use with Codex and compatible with the Agent Skills open standard.

Layered security patterns for autonomous trading agents that sign and send transactions — prompt-injection filters on external data, independent per-tx/daily hard spend limits, mandatory pre-send simulation with a required `min_amount_out`, drawdown-based circuit breakers, a dedicated session hot wallet (never the treasury), and private mempool routing (e.g. Flashbots) with per-strategy slippage and deadline. Pre-deploy checklist treats no single check as sufficient.

MCPorter CLI skill for listing, configuring, authenticating, and calling MCP servers and tools directly via HTTP or stdio, with CLI and type generation support

Provides Ruzzy patterns for Ruby fuzzing with coverage-guided testing to discover vulnerabilities in Ruby C extensions

Drafts professional emails for various business scenarios including client responses, meeting follow-ups, cold outreach, and difficult conversations, with tone guidelines and subject line best practices for each situation.

Analyzes code naming conventions across variables, functions, classes, files, database tables, and API endpoints, identifying inconsistencies and suggesting improvements by language.

A fallback web crawling skill that uses Firecrawl for single-page scraping and SerpApi for YouTube search, video metadata, and transcript retrieval when normal web_fetch fails or is blocked.

A Claude Code plugin for AI-assisted coding in MapleStory World (MSW), part of the MSW AI Coding Plugins collection currently under development.

Designs and automates Extract, Transform, Load data pipelines with support for multiple source connectors (PostgreSQL, MySQL, MongoDB, APIs, files), data transformation and cleaning, and loading into data warehouses like BigQuery, Snowflake, and Redshift.
