-
Decision Tracking
Architecture Decision Records (ADR) templates, sequential numbering, decision documentation patterns, and decision history management. Use when creating ADRs, documenting architectural decisions, tracking decision rationale, managing decision lifecycle, superseding decisions, searching decision history, or when user mentions ADR, architecture decision, decision record, decision tracking, or decision documentation.

-
blockrun
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")

progressive-metadata
Pattern for creating skills with YAML frontmatter that enables progressive disclosure and token optimization. Use when building skills, optimizing context usage, or implementing domain expertise with minimal token overhead. Demonstrates how to structure SKILL.md files with metadata-driven loading that achieves 84% token reduction compared to manual instructions. Triggers on "create skill with metadata", "token optimization", "progressive disclosure", "skill frontmatter", "efficient skill design".

-
delphi
This skill should be used when the user asks to "use delphi", "ask delphi", or wants multiple parallel oracle investigations of the same question to discover divergent insights. Delphi launches multiple oracle agents simultaneously with identical prompts, allowing them to independently explore and potentially discover different paths, clues, and solutions. Results are saved to .oracle/[topic]/ and synthesized into a final document.

agent-project-manager
Expert project manager specializing in project planning, execution, and delivery. Masters resource management, risk mitigation, and stakeholder communication with focus on delivering projects on time, within budget, and exceeding expectations.

-
Researching Features
Use this whenever a user wants to add a new feature or explitly states to research a feature/API or building a plan for a new feature. It iterviews the user for feature details (if not provided), research the best API/service for their needs, confirm choice, then gather all implementation notes for their request and save them as a .claude/plans file.

ai-product
Every product will be AI-powered. The question is whether you'll build it right or ship a demo that falls apart in production. This skill covers LLM integration patterns, RAG architecture, prompt engineering that scales, AI UX that users trust, and cost optimization that doesn't bankrupt you. Use when: keywords, file_patterns, code_patterns.
