Recover lost context after session compaction or when information from previous sessions is needed. Use when: user mentions "what were we working on", "I lost context", "before the compact", "previous session", or asks about decisions/implementations/discussions that aren't in current context. Also use proactively when you notice references to prior work you lack context for.

Write efficient resolvers with DataLoader, batching, and N+1 prevention

Collect a single Schwab MCP data snapshot (accounts, quotes, indicators, option chains) with a five-minute cache so trading agents can reuse consistent inputs. Use whenever an options persona needs fresh risk, market, or chain data before recommending trades.

Use when executing implementation plans with independent tasks in the current session

Next.js API Routes - Route handlers, middleware, edge runtime

Break down PRD and Architecture into implementable engineering tasks. Use when user wants to create a task list, plan implementation work, decompose features into stories and tasks, or needs to translate requirements into actionable engineering work. Reads from docs/PRD.md and docs/ARCHITECTURE.md, outputs docs/TASKS.md.

Master Terraform state management including remote backends, locking, workspaces, and state operations

Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.

Analyzes the conversation to extract actionable guidance and persists it to ~/.claude/lessons/ with triggers in ~/.claude/CLAUDE.md.

Build working prototypes from PRDs with mock data and stubbed integrations. Use when user has a PRD, spec, or feature description and wants a clickable demo to validate flows before full implementation. Triggers: build a prototype, functional prototype, make a demo, implement this PRD, prototype this spec, make it clickable.

Implement security best practices including secrets management, policy as code, and compliance scanning

Generate BPMN 2.0 compliant XML files from natural language process descriptions OR from structured markdown business process documents. Use this skill when a user wants to create a BPMN workflow, convert a business process to BPMN XML, model a workflow diagram, or generate process definitions. Triggers on requests like "create a BPMN", "generate workflow XML", "model this process", "convert to BPMN 2.0", "create process diagram", "build workflow", or "convert this markdown to BPMN".

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Apply consulting methodologies from McKinsey, BCG, Bain, and Accenture for structured problem-solving and strategic analysis. Use when analyzing business problems, developing strategy, structuring presentations, evaluating M&A, sizing markets, improving profitability, managing projects, or driving organizational change.

XML tag structure patterns for Claude Code agents and commands. Use when designing or implementing agents to ensure proper XML structure following Anthropic best practices.

Master PostgreSQL SQL fundamentals - data types, tables, constraints, schema design

Guide users through creating Agent Skills for Claude Code. Use when the user wants to create, write, author, or design a new Skill, or needs help with SKILL.md files, frontmatter, or skill structure.
