The skills/shadcn skill is graded A by polygraph under litmus-skill-v3, as of 2026-07-05, anchored to its content hash.
Graded under litmus-skill-v3; the current skill methodology is litmus-skill-v2. A re-run may change the grade.
Self-reported “Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI, including chat interfaces. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes,…” — the skill’s own SKILL.md description at the graded commit, not part of the grade.
A static safety grade — a deterministic scan of the skill’s SKILL.md and bundled files. An A means static-clean, not behavioral proof: a skill’s instructions are interpreted by an agent at runtime.

The skill litmus is open and deterministic. Point it at the skill directory and compare the grade and content hash — a false grade is falsifiable, not merely disputable.

- What does the A skill grade mean for skills/shadcn?
- It’s a static safety grade(A/B/D/F) from a deterministic scan of the skill’s
SKILL.mdand bundled files. An A means static-clean — not behavioral proof, since a skill’s instructions are interpreted by an agent at runtime. - What did polygraph check?
- Three static checks: S-01 prompt-injection and context-poisoning, S-03 data-exfiltration instructions, and S-04 dangerous bundled commands. The full battery is in the methodology.
- How do I reproduce this grade?
- Run
npx -p @polygraphso/litmus polygraphso-litmus-skill <skill-dir>. The scan is open and deterministic, anchored to the skill’s content hash, so the same directory yields the same grade.
