Run a Binstack decision-making analysis. Binstack chooses between competing options by checking each against stack-ranked priorities using binary materiality (does this option materially move the needle -- yes or no?) rather than weighted scoring. Best for: (1) Prioritizing a backlog of features, projects, or initiatives where you need one winner, (2) Choosing between alternatives that seem 'close' on paper but differ in strategic impact, (3) Decisions where defensibility matters -- explaining 'why this and not that' to stakeholders. Not ideal for: cost/effort tradeoff analysis (use ROI), exploring a problem space (use HEAD), or decisions with a single dominant criterion that needs no framework. Trigger on: 'binstack', 'prioritize these options', 'which should we build next', 'rank these features', or when the user has multiple options and needs a clear, defensible pick.

Guide users through the Bulletproof Problem Solving (BPS) seven-step framework from the book by Charles Conn and Robert McLean. Use this skill whenever the user mentions problem solving, strategic thinking, decision making, logic trees, issue trees, disaggregation, MECE, workplanning, hypothesis-driven analysis, root cause analysis, structured problem solving, McKinsey-style problem solving, or wants help thinking through a complex personal, business, or societal problem. Also trigger when the user says things like "help me think through X", "how should I approach this problem", "I need to make a decision about Y", "help me break this down", "what's the best framework for this", or asks about prioritization, synthesis, or storytelling for a recommendation. This skill is especially useful for entrepreneurs evaluating opportunities, making business strategy decisions, career choices, investment decisions, or tackling any complex problem with multiple variables.

Guides founders and product teams through rigorous customer/user research interviews. Use this skill whenever the user mentions customer interviews, user research, customer discovery, talking to users, validating a startup idea, interview guides, customer development, user interviews, discovery interviews, or wants help preparing questions for potential customers. Also trigger when users mention wanting to understand customer needs, test a value proposition, get feedback on an early product concept, or combat bias in customer conversations. This skill is especially relevant for early-stage founders but applies at any stage of product development.

Design software using Domain-Driven Design (DDD). Guides you through strategic design (Bounded Contexts, Context Maps, subdomains) and tactical design (Entities, Value Objects, Aggregates, Repositories, Domain Events). Works in either imperative/OOP style (Evans) or functional/FP style (Ghosh). Trigger on: 'design this domain', 'model this domain', 'DDD for', 'bounded context for', 'aggregate design', 'domain model', or when you need to translate business requirements into a rich domain model before writing code.

Conducts enterprise-grade research with multi-source synthesis, citation tracking, and verification. Produces citation-backed reports through a structured pipeline with source credibility scoring. Triggers on "deep research", "comprehensive analysis", "research report", "compare X vs Y", "analyze trends", or "state of the art". Not for simple lookups, debugging, or questions answerable with 1-2 searches.
