Translate PRD intent, roadmap asks, or product discussions into an implementation-ready capability plan that exposes constraints, invariants, interfaces, and unresolved decisions before multi-service work starts. Use when the user needs an ECC-native PRD-to-SRS lane instead of vague planning prose.

DEPRECATED redirect — this skill was renamed to configs-variations. Do not use this skill; invoke configs-variations instead. Kept only so old references to aiconfig-variations still point users to the new name.

Idiomatic C# and .NET patterns, conventions, dependency injection, async/await, and best practices for building robust, maintainable .NET applications.

Full-stack diagnostic for agent and LLM applications. Audits the 12-layer agent stack for wrapper regression, memory pollution, tool discipline failures, hidden repair loops, and rendering corruption. Produces severity-ranked findings with code-first fixes. Essential for developers building agent applications, autonomous loops, or any LLM-powered feature.

Create and manage prompt snippets — reusable text blocks referenced inside config variation prompts. Keeps common instructions, personas, and guardrails consistent across multiple configs.

Create and configure configs in LaunchDarkly. Helps you choose between agent vs completion mode, create the config, add variations with models and prompts, and verify the setup.

Push decisions to Arbiter Zebu for async human review. Use when you need human input on plans, architectural choices, or approval before proceeding.

WHOOP Central - OAuth + scripts to fetch WHOOP data (sleep, recovery, strain, workouts). Use when user asks about their sleep, recovery score, HRV, strain, or workout data.

Build command-line interfaces with async-first design, composable commands, and proper output formatting. Use when creating CLI tools, commands, or interactive terminal applications.

Testing methodologies, test-driven development (TDD), unit and integration testing, and testing best practices across multiple frameworks. Use when the user needs to write tests, implement TDD, or improve test coverage and quality.

Systematic debugging strategies, troubleshooting methodologies, and problem-solving techniques for code and system issues. Use when the user encounters bugs, errors, or unexpected behavior and needs help diagnosing and resolving problems.

Analyzes your recent Claude Code chat history to identify coding patterns, development gaps, and areas for improvement, curates relevant learning resources from HackerNews, and automatically sends a personalized growth report to your Slack DMs.

Onchain agent messaging on Base - post to feeds, send DMs, explore other agents

Use when user needs capabilities Claude lacks (image generation, real-time X/Twitter data) or explicitly requests external models ("blockrun", "use grok", "use gpt", "dall-e", "deepseek")

Spec a new feature — recall architecture knowledge, create a spec document, build an implementation plan, and break into tasks.

Work with advanced layer types including WMS, WFS, WMTS, OGCFeatureLayer, MapImageLayer, CatalogLayer, MediaLayer, and dynamic data layers. Use for OGC services, server-side rendering, and georeferenced media content.

Generate Advanced Custom Fields (ACF) Local JSON configurations for WordPress from visual designs or HTML structures. Use when creating ACF field groups, converting designs to ACF schemas, building WordPress custom fields from mockups, or when working with ACF Pro Local JSON format. Supports flexible content, repeaters, clone fields, and all ACF field types.

Parse Microsoft Outlook PST and OST files using libpff and pst-utils to extract message content, headers, attachments, deleted items, and MAPI metadata, including recovery of items from the Recoverable Items folder. Use when conducting email forensic investigations, legal e-discovery, or incident response that requires reconstructing communication patterns or tracing message routing from Outlook archives.

Build effective detection rules using Splunk Search Processing Language (SPL) correlation searches to identify security threats in SOC environments.
