Looks up Seoul real-time subway arrival information through a `KSKILL_PROXY_BASE_URL` proxy that wraps the official Seoul Open Data API, so users never handle the upstream OpenAPI key directly. Returns line, direction, first/second arrival messages, and seconds until arrival per station, with an explicit "as of" timestamp because the data changes second-by-second.
Builds and manages webhook-based integrations for real-time event processing, including endpoint creation with signature verification, event routing to multiple handlers, data transformation, and multi-service orchestration for services like Stripe, CRM, and CI/CD systems.

Improves image quality by enhancing resolution, sharpness, and clarity, including upscaling, edge enhancement, text clarity improvement, and compression artifact reduction for screenshots and photos.
Enables template-based document generation using Jinja2 syntax for Word, Excel, and PowerPoint files. Supports mail merge for bulk document creation from CSV data, conditional content rendering, and variable substitution across multiple document formats.
A Claude skill for creating and maintaining brand style guides, helping marketing teams ensure consistent brand identity across materials.
Looks up Daiso store-specific product stock through Daiso Mall's official store-search, product-search, and store-pickup-stock APIs (`searchStores` → `searchProducts` → `getStorePickupStock`), wrapped by the `daiso-product-search` Node package and an end-to-end `lookupStoreProductAvailability` helper. Asks for the store name and product keyword first when missing and explicitly notes that the official surfaces don't expose in-store aisle/shelf positions.
Evidence-first live-messaging workflow for iMessage/DM retrieval, recovering a recent one-time code, and inspecting a thread before replying — not email work. Forces the agent to name the exact message surface (local Messages, X/social DM, other browser-gated source), sender/service, and time window, and returns explicit status (`read` / `code-found` / `blocked` / `awaiting reply draft`) instead of improvising raw database access.
Automates WooCommerce store operations including order processing pipelines with payment validation and fraud checks, inventory synchronization across multiple sources, product bulk updates, and customer workflow management.
Reviews code for security vulnerabilities and recommends secure coding practices to prevent common attack vectors like injection, XSS, and authentication flaws.
A Claude skill for creating and managing Apple Shortcuts to automate workflows on iOS and macOS.

A skill from the Awesome GitHub Copilot community collection that helps build premium frontend UI with best practices, design standards, and polished user interface patterns for web applications.
Evidence-first mailbox workflow for triage, drafting, replying, and proving a message actually landed in Sent — not a generic writing skill. Resolves which mailbox account and thread are in play, reads thread history before composing, and reports exact status (`drafted` / `approval-pending` / `sent` / `blocked` / `awaiting verification`) with sent-copy proof when claiming a send succeeded.
Generates professional PDF invoices from structured data and templates with company branding, itemized line items, tax calculations, and payment details using ReportLab and DOCX-to-PDF conversion.
Automates security monitoring, threat detection, and incident response workflows. Provides rule-based and ML-powered anomaly detection for authentication attacks, data exfiltration, and malware, with automated alerting, containment, and compliance monitoring.
Prevent Ethereum hashing bugs in JS/TS by never using Node's `crypto.createHash('sha3-256')` (which is NIST SHA3, not Ethereum Keccak-256) and using Keccak-aware helpers from `ethers`, `viem`, or `web3` instead — selectors, EIP-712 typeHash, storage-slot math, address derivation. Includes copy-paste patterns for ethers v6 (`id`, `solidityPackedKeccak256`), viem, web3.js, and a `grep` snippet for auditing existing code.
Track CJ대한통운 and 우체국 parcels by invoice number with official carrier endpoints, and structure the workflow around a carrier adapter that can grow to more couriers later.

Skill creation guide for building effective Claude Code skills with specialized knowledge, workflows, and tool integrations
Unify scattered notifications across GitHub, Linear, local hooks, desktop alerts, and connected chat/email into one ECC-native lane with a severity model (Critical/High/Medium/Low), event pipeline (capture → classify → route → collapse duplicates → attach action), and digest-first defaults. Prefers existing ECC primitives (skill, hook, agent, MCP) over a new notification product and always pairs each signal with the next operator action.
An open skills marketplace by Binance that gives AI agents native access to crypto — search tokens, execute trades, track wallets, monitor signals, and interact with DeFi protocols through natural language across any agent framework.
Reduces PDF file sizes with configurable compression levels ranging from minimal (archival quality) to maximum, supporting image optimization, resolution reduction, and batch processing for web, email, or print use cases.
Solidity AMM / liquidity-pool / swap-flow security checklist with hardened OpenZeppelin patterns — enforces CEI ordering and `nonReentrant`, blocks donation/inflation attacks by tracking internal `_totalAssets` instead of `token.balanceOf(address(this))`, requires Uniswap V3 TWAP instead of spot price, mandatory `amountOutMin`/`deadline` on swaps, `FullMath.mulDiv` for overflow-sensitive reserve math, and `Ownable2Step` admin controls. Ends with a slither / echidna / forge fuzz audit step.
A collection of 65 Claude Code skills and 9 workflows with progressive disclosure, covering full-stack development including context engineering and Atlassian integration.
