The core library for Astronomy and Astrophysics in Python. Provides data structures for coordinates, time, units, FITS files, and cosmological models. Essential for observational data reduction and theoretical astrophysics. Use when working with astronomical coordinates (RA/Dec), physical units, FITS files, time scales, WCS, cosmology, or astronomical tables.
intent-plan
by ArcBlock
Transform approved Intent into executable phased plan with strict TDD. Each step requires tests first (happy/bad/edge/security cases), then implementation. Use after /intent-review when ready to start development.
pricing-strategy
by JK-0001
Price a product or service for a solopreneur business. Use when deciding how much to charge, choosing between pricing models, structuring tiers, handling price objections, and adjusting prices over time. Covers value-based pricing, competitor benchmarking, psychological pricing tactics, pricing tiers design, and price testing. Trigger on "how should I price this", "pricing strategy", "what should I charge", "pricing tiers", "am I undercharging", "pricing model", "how to price my product", "raise my prices".
unit-economics
by JK-0001
Calculate, understand, and improve the unit economics of a solopreneur business. Use when figuring out if the business is actually profitable per customer, when CAC or LTV numbers are needed, when evaluating whether a pricing or acquisition strategy is sustainable, or when making data-driven decisions about marketing spend and pricing. Covers CAC, LTV, payback period, contribution margin, and the feedback loops between them. Trigger on "unit economics", "CAC", "customer acquisition cost", "LTV", "lifetime value", "payback period", "is my business profitable", "contribution margin", "am I making money per customer", "should I spend more on marketing".
idea-validation
by JK-0001
Validate a business idea before investing time or money. Use whenever a solopreneur has a raw idea and needs a structured process to stress-test it against reality — covering problem definition, demand evidence, competitive context, customer discovery, riskiest-assumption testing, and a scored go/no-go decision. Trigger on phrases like "validate my idea", "is this worth building", "should I pursue this", "test my business idea", "does this idea have legs".
product-roadmap
by JK-0001
Build and manage a product roadmap for a solopreneur business. Use when deciding what to build next, prioritizing features, planning product development over quarters, communicating plans to customers or stakeholders, or managing scope and expectations. Covers prioritization frameworks, roadmap structure, customer feedback integration, and saying no to feature requests. Trigger on "product roadmap", "what to build next", "feature prioritization", "roadmap planning", "product strategy", "feature requests".
tpm-spec-trace-ids
by ozten
Annotate a Spec/PRD with Feature IDs and generate a Coverage Index. Use when user wants to add spec tags to a vision document, create F-nnn identifiers, set up traceability, or initialize a PRD framework for phased development.
error-recovery
by mgd34msu
"ALWAYS load before starting any task. Defines systematic recovery procedures when things go wrong during execution. Covers tool failures, build errors, test failures, type errors, and unexpected runtime results. Includes tiered escalation (retry, fallback, memory-informed diagnosis, orchestrator escalation) and post-recovery logging to prevent recurrence."
tpm-roadmap-slice
by ozten
Generate a Phase Spec/PRD by extracting features from an annotated Vision PRD. Use when user wants to create quarterly phase documentation, extract requirements from vision, plan a development phase, or decompose features into R-nnnn requirements. Requires annotated Vision PRD with F-nnn tags and Coverage Index.
socratic-debate
by plinde
This skill should be used when conducting structured multi-perspective debates to stress-test ideas, evaluate tradeoffs, or reach well-reasoned decisions. Provides the Socratic debate framework with 4 subagent roles.
stably-sdk-rules
by stablyai
AI rules and SDK reference for writing tests with Stably Playwright SDK. Use this skill when writing or modifying Playwright tests with Stably AI features. Triggers on tasks involving aiAssert, agent.act(), page.extract(), page.getLocatorsByAI(), Inbox (email testing), or when deciding between Playwright vs Stably SDK methods. Includes best practices for AI assertions, extraction, locator finding, autonomous agents, and email inbox testing.
tpm-spec-verify
by ozten
Enrich a Phase Sepc/PRD with Quality Requirements (Q-nnn) and Acceptance Criteria (AC-nnnn). Use when user wants to add QA perspective, define test criteria, identify non-functional requirements, add verification steps, or prepare a Phase PRD for test planning.
testing-strategy
by mgd34msu
"Load PROACTIVELY when task involves writing tests, improving coverage, or test infrastructure.
