## Published listings

- [Claim Extractor](https://agentstack.voostack.com/l/skill-leventilo-mobius-claim-extractor) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-claim-extractor`
  Activate when the orchestrator needs the paper's verifiable claims separated from prose so each can be tested against the simulator.
- [Primitive Generator](https://agentstack.voostack.com/l/skill-leventilo-mobius-primitive-generator) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-primitive-generator`
  Generate runnable Python code for each primitive in a SimSpec — sources, media, detectors, operators, fields, observables. Output is validated by science-integrity before execution. Uses an indexed pattern library; falls back to LLM synthesis when no pattern matches. Run after simspec-author, before science-integrity.
- [Paper Parser](https://agentstack.voostack.com/l/skill-leventilo-mobius-paper-parser) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-paper-parser`
  Ingest an arXiv-style physics PDF and produce a structured paper record with extracted equations (LaTeX + sympy), figures (images + captions + inline claim quotes), and numerical claims with provenance. Uses Opus 4.7 vision for dense scientific diagrams. Run first in the DAG before physics-interpreter.
- [Paper Diff](https://agentstack.voostack.com/l/skill-leventilo-mobius-paper-diff) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-paper-diff`
  Compare simulation output to the original paper's reference figures using Opus 4.7 vision plus deterministic image metrics. Produces structured diff with feature-level present/missing/spurious lists and a similarity score. Run after primitive-generator + execution, before pitch the result to the user. Distinct from science-integrity's figure_diff (which is one of five integrity checks); paper-dif…
- [Science Integrity](https://agentstack.voostack.com/l/skill-leventilo-mobius-science-integrity) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-science-integrity`
  Parallel critic agent that enforces physical invariants on Mobius SimSpecs and simulation outputs. Runs five bundled deterministic checks — units, CFL stability, conservation laws, figure-diff, and claim-match — and blocks or warns upstream generators. Use whenever a SimSpec or simulation artifact is produced.
- [Physics Interpreter](https://agentstack.voostack.com/l/skill-leventilo-mobius-physics-interpreter) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-physics-interpreter`
  Translate paper-parser's extracted equations, claims, and surrounding text into a typed physics sub-tree of the SimSpec — governing equations, boundary conditions, initial conditions, declared constants, regime classification, and named approximations. Run after paper-parser, before simspec-author.
- [Narration](https://agentstack.voostack.com/l/skill-leventilo-mobius-narration) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-narration`
  Produce time-aligned natural-language narration for a Mobius simulation, explaining the physics happening at each visible moment in clear prose. Generates the narration.segments[] sub-tree of SimSpec from physics, primitives, and execution telemetry. Run after primitive-generator and (typically) after simulation execution.
- [Viz Mapper](https://agentstack.voostack.com/l/skill-leventilo-mobius-viz-mapper) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-viz-mapper`
  Translate a verified SimSpec into a typed viz_spec.json conformant to the V8 viz_spec.schema.json. Output JSON only — no HTML, no CSS, no JavaScript. Server-side ajv validation enforces shape post-receive (grammar path is currently OFF — schema exceeds Anthropic compiled-grammar size cap). The frontend renderer (public/runtime/render.js) consumes viz_spec + frames + narration + provenance and ren…
- [Simspec Author](https://agentstack.voostack.com/l/skill-leventilo-mobius-simspec-author) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-simspec-author`
  Compose a validated SimSpec from paper-parser, physics-interpreter, and claim-extractor outputs. Use when the orchestrator has upstream artifacts and needs a typed canonical spec before primitive-generator runs. The spec is validated against simspec.schema.json; ambiguities are explicitly logged.
- [Shader Dev](https://agentstack.voostack.com/l/skill-leventilo-mobius-shader-dev) — Skill · Free · security-reviewed — `agentstack add skill-leventilo-mobius-shader-dev`
  Comprehensive GLSL shader techniques for creating stunning visual effects — ray marching, SDF modeling, fluid simulation, particle systems, procedural generation, lighting, post-processing, and more.
