Use the railstart gem to scaffold Rails applications, run `railstart init` or `railstart new`, create or refine railstart presets, customize `~/.config/railstart/config.yaml`, debug config or post-action behavior, or contribute changes to the gem itself. Trigger when a task involves Railstart CLI usage, preset authoring, YAML question or post-action configuration, template post-actions, or the gem's CLI/config/generator implementation.
Execute the Flywheel bead lifecycle — find, claim, implement, review, close
Set up and configure Arize tracing for Claude Code sessions or Agent SDK applications. Use when users want to set up tracing, configure Arize AX or Phoenix, create a new Arize project, get an API key, enable/disable tracing, or troubleshoot tracing issues. Triggers on "set up tracing", "configure Arize", "configure Phoenix", "enable tracing", "setup-claude-code-tracing", "create Arize project", "get Arize API key", "agent sdk tracing", or any request about connecting Claude Code or the Agent SDK to Arize or Phoenix for observability.
Insert detected flake polygons into KLayout as GDS geometry using the geometry skill's add_polygon.py. Use after combine completes to commit traces.json contours as polygons on the correct layers.
Transform detection results into the common full_stack coordinate system, build unified traces.json, and draw overlay images. Use after align and detect steps are complete.
Research workflows for the Rijksmuseum MCP+ server. Use this skill whenever the user wants to search the Rijksmuseum collection, look up artwork details, explore iconographic themes, inspect high-resolution images, trace provenance, browse curated sets, or answer any art-historical question that could be addressed through the Rijksmuseum's holdings of ~832,000 artworks.

When the user wants to optimize food and beverage supply chains, manage perishability, ensure food safety, or handle retail distribution. Also use when the user mentions "food supply chain," "beverage distribution," "HACCP," "food safety," "perishable logistics," "shelf life management," "FEFO," "farm to fork," "CPG distribution," "grocery supply chain," or "fresh produce logistics." For retail allocation, see retail-allocation. For promotional planning, see promotional-planning.
When the user wants to solve cutting problems with guillotine constraints, implement edge-to-edge cutting, or optimize guillotine cutting patterns. Also use when the user mentions "guillotine cuts," "edge-to-edge cutting," "straight cuts only," "two-stage cutting," "three-stage cutting," "n-stage guillotine," or "guillotine cutting stock problem." For general cutting, see 2d-cutting-stock or 1d-cutting-stock. For irregular shapes, see nesting-optimization.
Use when writing in a creator's voice, analyzing a creator's style, or maintaining consistency across content.
Multi-pass first principles analysis for any domain — business, personal decisions, creative projects, career, health, relationships. Decomposes problems to fundamental truths, challenges assumptions through 4 universal lenses (Constraints, Resources, Human, Context), and reconstructs solutions from verified ground truths only. Use when the user says "first principles", "from first principles", "analyze fundamentals", "challenge assumptions", "decompose problem", "why does this cost so much", "is this the right approach fundamentally", "what are we really solving", "strip away assumptions", "should I really be doing this". Also use when the user is stuck on a problem that seems intractable, when conventional approaches have failed, when questioning whether the whole approach is wrong, or when facing a "we've always done it this way" situation — whether in business, life, or creative work. Do NOT use for quick factual questions, time-critical decisions, trivial/low-stakes choices, or domains already optimized
Philosophical and methodological framework for scientific inquiry grounded in Peircean pragmatism, effective theory construction, and principled iterative model building. Load when reasoning about scientific methodology, model construction and criticism, evidential standards, or the relationship between mechanistic understanding and statistical modeling.
Framework-agnostic testing principles — test philosophy, structure, mocking boundaries. Use when writing, reviewing, or debugging tests.
Use when working with FS25 textures, DDS formats, normal maps, specular maps, texture naming conventions, or resolution guidelines.
Align microscope stack images to a GDS fabrication template using lithographic marker detection. Computes image→GDS transform and commits warped image + material contours to KLayout.
Register source microscope images to the full_stack coordinate system using SIFT (same-substrate) or Chamfer+DE (cross-substrate) alignment. Use when aligning bottom_part, top_part, or other source images to the full_stack reference image for van der Waals stack detection.
