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.

Composes three-part DACP bundles from skill library artifacts. Determines fidelity level, queries catalog, and records assembly rationale.

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.

Foundational measurements and relationships. The axioms of the system — numbers, distance, angles, and the geometry of seeing.

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

Passive Sensing, Threat Assessment, and Coordinated Signaling for Agent Systems.

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.
