Triggers for automatically invoking the decision-framework skill before irreversible or high-blast-radius operations. Use as a checkpoint: when a proposed action matches a trigger pattern, pause and run the appropriate framework (first-principles, inversion, decision matrix, second-order thinking) before proceeding. Prevents ad-hoc calls from becoming regret.

Carol Dweck's *Mindset: The New Psychology of Success* (2006) reframed a long-running thread of educational-psychology research on "implicit theories of intelligence" into a vocabulary teachers could

Political philosophy from social contract theory to global justice. Covers the social contract (Hobbes, Locke, Rousseau, Rawls), theories of justice (Rawls, Nozick, Sen), liberty (positive/negative), rights (natural, human, civil), democracy and governance, communitarianism, feminism as political philosophy, Confucian political philosophy (ren, li, rectification of names), anarchism, Marxism, postcolonial philosophy, and cosmopolitanism. Use when analyzing political institutions, rights, justice, freedom, governance, or the legitimacy of authority.

Quantum mechanics from wave-particle duality through entanglement and measurement. Covers the photoelectric effect, de Broglie wavelength, Heisenberg uncertainty principle, the Schrodinger equation (time-dependent and time-independent), wave functions and probability, quantum states and superposition, the hydrogen atom (energy levels, quantum numbers), spin, Pauli exclusion principle, quantum tunneling, Feynman path integrals (conceptual), QED basics, entanglement (Bell's theorem), the measurement problem, and Dirac notation. Use when analyzing phenomena at atomic or subatomic scales where classical physics breaks down.

Agile and Lean software development methodologies for iterative, adaptive project execution. Covers Scrum (roles, ceremonies, artifacts), Kanban (WIP limits, flow metrics), XP (TDD, pair programming, CI), SAFe overview, Lean Software Development (Poppendieck's 7 principles), user stories (INVEST criteria), estimation via story points and velocity, and the Agile Manifesto's values and principles. Includes Cynefin framework for methodology selection and GSD's relationship to Agile as a structured Lean variant.

A postmortem is the work product that converts an incident from a surprise into learning. A *blameless* postmortem does this without punishing the people closest to the incident — not because punishme

Fact-checking and source verification workflow for research documents. Launches parallel fact-checkers, aggregates findings, applies corrections systematically.

Design heuristics for three-dimensional interaction — input modalities (6DoF controllers, gaze, gesture, voice), selection and manipulation techniques (ray-cast, virtual hand, go-go, world-in-miniature), navigation (teleport, continuous, redirected walking), and feedback loops (haptic, audio, visual). Covers Fitts' law in 3D, discoverability vs affordance, safe-zone design, and comfort/simulator sickness mitigation. Use when designing VR/AR interactions, immersive walkthroughs, or any input system where the user's body is the controller.

Augmented reality succeeds or fails on registration — the precise alignment of virtual content with the physical world. A perfectly rendered virtual object floating six inches from where it should be

Philosophical theology — the use of philosophical tools to analyze and evaluate theological claims. Covers classical arguments for and against the existence of God (cosmological, ontological, teleological, moral, evil), the divine attributes (simplicity, omniscience, omnipotence, eternity, impassibility), the relation of faith and reason, religious epistemology, and the boundary between natural theology and revealed theology. Use when a query asks whether a theological claim is rationally defensible, how a divine attribute should be understood, or how philosophical frameworks across traditions have engaged religious questions.

Tools and machines as the leverage-amplification layer of the trades — how hand tools, powered tools, and programmable machines differ in what they amplify, what they constrain, and what skill they demand. Covers the tool-to-machine progression, the Nasmyth steam-hammer lineage of precision power, the block-making machinery at Portsmouth as the first mass-production machine shop, and the modern CNC/robotics layer. Use when selecting tools for a job, justifying a tool purchase, or teaching a learner why tools are organized the way they are.

Thinking frameworks for decisions and problem analysis. Use when evaluating options, root causes, or prioritizing.

Deterministic git operations with state verification for skill-creator managed repos. Use when managing repos, branches, worktrees, or contribution workflows.

Complex systems and emergent behavior — chaos theory, fractals, neural networks, cellular automata, and computability. Analyzes dynamical systems for chaos via Lyapunov exponents, classifies bifurcations, measures fractal dimension, and models emergent phenomena. Use when analyzing chaotic systems, computing Lyapunov exponents, classifying bifurcations, measuring fractal dimension, modeling neural networks, or studying emergent behavior from simple rules.

Periodic phenomena and frequency analysis. How repetition creates structure — from simple oscillation to Fourier decomposition.

Use trace-mcp apply_codemod for any bulk mechanical change instead of repeated Edit calls. Activate whenever the same edit pattern would be applied 2+ times, across one file or many.

Simplify code while preserving behavior, public contracts, and side effects. Favor explicit code and local clarity over clever or compressed constructs.

Create atomic commits by staging the right files, analyzing the staged diff, composing a conventional commit message, and optionally pushing.

This skill should be run only when the user explicitly invokes it. Orchestrates end-to-end task implementation — understands the task, assesses complexity, implements directly or via a team of subagents for complex work, and always finishes with a code-polish pass.
