LLM & Agents

Unit testing framework for Python using pytest. Use when writing test cases, validating code behavior, checking test coverage, or debugging test failures.

Developer for Claude Orchestrator. Implements tasks according to Tech Lead instructions, applies design tokens, and reports completion. Use when asked to implement code or execute development tasks for the orchestrator.

Graph algorithms for network analysis including shortest paths, cycle detection, and connectivity analysis. Create directed/undirected graphs with weighted edges. Use when modeling currency exchange networks, detecting arbitrage opportunities via negative cycles, finding optimal trading routes, calculating path lengths, analyzing network topology, or working with any connected data structures. Supports Bellman-Ford, Dijkstra, and other graph algorithms.

Comprehensive testing guidelines for Vitest and React Testing Library. Covers quality standards, AAA pattern, naming conventions, branch coverage, and best practices. Reference this skill when creating or updating test code during Phase 2 (Testing & Stories).

UI/UX Designer for Claude Orchestrator. Creates design specifications with design tokens (colors, fonts, spacing) and component specs. Use when asked to create design specifications or define design tokens for the orchestrator.

Tech Lead for Claude Orchestrator. Creates implementation instructions based on planning documents and design specifications. Use when asked to create developer instructions or technical implementation guides for the orchestrator.

Perform vector similarity search using embeddings. Use when implementing semantic search, finding similar documents, or building recommendation systems. NOT needed for basic content aggregation or API integration.

Implement routing strategies for warehouse order picking. Use this skill when determining optimal pick sequences, applying heuristic routing methods, calculating travel distances, or optimizing picker movements through storage areas.

Product Planner for Claude Orchestrator. Creates planning documents with product vision, features, user flows, and requirements. Use when asked to plan a task or create a planning document for the orchestrator.

Optimize inventory placement in warehouse storage. Use this skill when assigning SKUs to locations, considering pick efficiency, implementing zone-based storage, or managing storage location assignments.

Balance inventory across warehouse locations for optimal fulfillment. Use this skill when redistributing stock between locations, optimizing inventory positioning, managing regional inventory levels, or planning inventory transfers.

Work with JSON data. Use for parsing API responses, config files, or structured data storage.

Manage warehouse operations including inventory control, location management, and process optimization. Use this skill when working with WMS systems, managing storage locations, tracking inventory movements, or optimizing warehouse workflows.

Guide for managing tasks within a session using bd (beads) for subtasks and local todo lists. Use this skill when breaking down plans into issues, tracking progress, managing dependencies, or coordinating work across sessions and agents. Triggers include requests to "manage tasks", "track progress", "break down this work", or questions about bd workflow.

Shared foundation for Oracle & Corrector agents. Establishes the source hierarchy for resolving conflicts between documentation, code, and specs. Load this skill first when investigating how the system works.

AI agents as force multipliers for quality work. Core skill for all 19 QE agents using PACT principles.

Apply the Holistic Testing Model evolved with PACT (Proactive, Autonomous, Collaborative, Targeted) principles. Use when designing comprehensive test strategies for Classical, AI-assisted, Agent based, or Agentic Systems building quality into the team, or implementing whole-team quality practices.

Focus testing effort on highest-risk areas using risk assessment and prioritization. Use when planning test strategy, allocating testing resources, or making coverage decisions.

Comprehensive mobile testing for iOS and Android platforms including gestures, sensors, permissions, device fragmentation, and performance. Use when testing native apps, hybrid apps, or mobile web, ensuring quality across 1000+ device variants.

Analyzes Rails applications and generates comprehensive upgrade reports with breaking changes, deprecations, and step-by-step migration guides for Rails 7.0 through 8.1.1. Use when upgrading Rails applications, planning multi-hop upgrades, or querying version-specific changes.
