polyviz SKILL.md skillA
polyviz from cognitive-fab/polygraph is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Turn Polygraph verification artifacts into clean, brand-consistent diagrams (SVG, optional PNG). polyviz is a DETERMINISTIC, artifact-derived renderer — same inputs produce byte-identical output and it makes no model call at render time. Use when the user wants to "visualize / diagram the verification", "draw the state machine / lifecycle", "render the counterexample / the bug the gate found", "show the fleet / compat / deploy-gate verdict", or "regenerate the figures for a report or post". It…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# polyviz — visualize the verification, don't redraw it
polyviz is the VISUALIZATION side of the Polygraph method (Polygraph audits,
polygen authors, polyrun executes, polyvers evolves, polynv elicits — polyviz
**draws**). Every mark it emits traces to a field in a Polygraph artifact, so the
picture cannot drift from the model that was actually checked. Rendering is a
pure function `artifacts → SVG`: no `Date.now()`, no randomness, sorted keys —
byte-identical on every run. An LLM may *invoke* polyviz; it never draws.
The CLI is `${CLAUDE_PLUGIN_ROOT}/bin/polyviz.mjs`:
```
polyviz render --in <dir|polyviz.json> --diagram <all|state-machine|invariants|counterexample|compat-gate|model-card> \
--out <dir> [--format svg[,png]] [--theme dark|light] [--tokens tokens.json] [--scale 2]
polyviz hash --in <dir|polyviz.json> --diagram <...> # sha256 per SVG, no files (determinism/CI check)
polyviz schema # print the viz-model JSON Schema
```
## Two ways to feed it
1. **A viz-model JSON** (`*.polyviz.json`) — the stable contract (`polyviz schema`
prints it). Pure `viz-model → SVG`: no user code executed, no optional deps

How to install
mdr add cognitive-fab/polygraph/polyviz@sha256:76bd8b4c924b0918The line at the top of this page pins the label git:20260909.55b506b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
