cfd-workflow

cfd-workflow is a skill for Claude Code from kimimgo/viznoir. It costs 102 tokens per session (446 once invoked), scanned A, original, MIT.

A workflow for turning computational fluid dynamics results into visual and numerical analysis. Computational fluid dynamics simulates how fluids move, including pressure, velocity, turbulence, wakes, and boundary layers.

In plain words
What is it for?
Rendering pressure and velocity fields, drawing streamlines, measuring pressure drops, examining boundary layers and wall shear, and summarizing statistics.
Why use it?
It maps common fluid-engineering questions to specific analysis steps and visualizations, making simulation results easier to inspect.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cfd-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

CFD Post-Processing Workflow

Standard Sequence

  1. inspect_data → identify velocity (U), pressure (p), turbulence (k, epsilon)
  2. cinematic_render(field="p", colormap="Cool to Warm") → pressure overview
  3. cinematic_render(field="U", colormap="Viridis") or slice at mid-plane
  4. streamlines(vector_field="U") → flow patterns, wake, recirculation
  5. plot_over_line → pressure drop (inlet→outlet), velocity profiles
  6. extract_stats → quantitative summary (min/max/mean)

Vocabulary → Tool Mapping

Expert says Tool Params
wake, 후류 streamlines seed downstream of body
pressure drop, 압력강하 plot_over_line field="p", point1=inlet, point2=outlet
boundary layer, 경계층 slice + plot_over_line wall-normal direction
wall shear cinematic_render field="wallShearStress", colormap="Plasma"
recirculation, 재순환 streamlines seed in low-velocity region
turbulence slice field="k" or "nut", colormap="Turbo"

Colormaps

  • Pressure: Cool to Warm (diverging)
  • Velocity: Viridis (sequential)
  • Temperature: Inferno (thermal)
  • Wall shear: Plasma (high contrast)
  • Turbulence: Turbo (structure emphasis)
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cfd-workflow is a skill published in the GitHub repository kimimgo/viznoir (17 stars, last pushed 4d ago), licensed MIT. It adds 102 tokens to every session and 446 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
