Use before committing staged changes when you need to verify all related documentation is current - systematically checks README, CLAUDE.md, CHANGELOG, API docs, package metadata, and cross-references rather than spot-checking only obvious files

Multi-agent development workflow system. Load when orchestrating development tasks, spawning subagents, or managing workflow phases.

When you need check documentation about Ruby classes, modules, and methods use this skill to get full details. Avoid check source code or use `ruby -e` for documentation unless absolutely necessary.

GitHub Actions workflow automation for intelligent CI/CD pipelines with adaptive optimization. Use for workflow creation, pipeline optimization, security scanning, failure analysis, and automated deployment strategies.

Build Vue 3 UI extensions for Directus with modern patterns, real-time data, and responsive design

LLM fine-tuning with LoRA, QLoRA, and instruction tuning for domain adaptation.

Multi-agent development workflow system for structured task execution. Use when working with tasks in .tasks/ directory, when user invokes /task, /explore, /research, /spec, /build, /review, or /refactor commands, or when Claude needs to understand the task orchestration system. Provides workflow state management, sub-agent coordination, and session persistence.

Processes images with Sharp, the high-performance Node.js library for resizing, converting, and optimizing images. Use when building image pipelines, generating thumbnails, or optimizing uploads server-side.

Research pipeline for topology-aware GNN representation learning on power grids using the PowerGraph benchmark. Use when (1) building physics-guided GNNs for power flow (PF), optimal power flow (OPF), or cascading failure prediction, (2) implementing self-supervised pretraining for power systems, (3) evaluating cascade explanation fidelity against ground-truth masks, or (4) conducting reproducible ML-for-power-systems research. Triggers include "PowerGraph", "power flow GNN", "OPF surrogate", "cascade prediction", "physics-guided GNN", "grid analytics ML", "power system representation learning".

Integrate external REST and GraphQL APIs with proper authentication (Bearer, Basic, OAuth), error handling, retry logic, and JSON schema validation. Use when making API calls, database queries, or integrating external services like Stripe, Twilio, AWS. Achieves 10-30x cost savings through direct execution vs LLM-based calls. Triggers on "API call", "REST API", "GraphQL", "external service", "API integration", "HTTP request".

Use when the user is exploring possibilities, asking for ideas, or expressing uncertainty. Trigger cues include "ideas", "alternatives", "what could we do", "brainstorm", "different approaches", "I'm not sure yet". Use this skill to generate distinct conceptual directions before any evaluation or refinement.

Real provider network data integration using local NPPES registry. Provides actual NPIs, provider names, specialties, and locations for cross-product integration.

Use when working with ES/NQ futures market data, before calling any Databento API - follow mandatory four-step workflow (cost check, availability check, fetch, validate); prevents costly API errors and ensures data quality

Creates slash commands for Claude Code following Sando's Golden Rule - only create commands that add intelligent value over bash (analysis, insights, multi-source aggregation, troubleshooting). Use when user requests new slash command or workflow automation that justifies token cost.

強制執行「先讀後寫」規範，確保 Claude 在修改任何檔案前完整閱讀相關代碼。當需要修改檔案時自動使用。

Orchestrate agile development workflows by invoking commands in sequence with checkpoint-based flow control. This skill should be used when the user asks to 'run the workflow', 'continue working', 'what's next', 'complete the task cycle', 'start my day', 'end the sprint', 'implement the next task', or wants guided step-by-step development assistance. Keywords: workflow, orchestrate, agile, task cycle, sprint, daily, implement, review, PR, standup, retrospective.

Backend Cloud Run/Express/Firestore do Sr Cardoso. Use quando criar ou alterar endpoints, auth JWT, regras de agenda, financeiro, branding, WhatsApp, cron jobs, ou modelagem Firestore.

Professional network reconnaissance and port scanning using nmap. Supports various scan types (quick, full, UDP, stealth), service detection, vulnerability scanning, and NSE scripts. Use when you need to enumerate network services, detect versions, or perform network reconnaissance.

Fix PPO training early-stop issues. Trigger when: (1) impossible drawdown values (>100%), (2) training stops too early, (3) need adaptive recovery instead of hard stop.

Crafts the pre-launch email sequence for VIPs and main list to build anticipation, drive preview traffic, and prime early conversion.
