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.

How do I reproduce this grade?

Run: npx -p @polygraphso/litmus polygraphso-litmus-skill . The scan is open and deterministic, anchored to the skill's content hash, so the same directory yields the same grade.

Q: What does the A skill grade mean for productclank-campaigns?

It's a static safety grade (A/B/D/F) from a deterministic scan of the skill's SKILL.md and bundled files. An A means static-clean — not behavioral proof, since a skill's instructions are interpreted by an agent at runtime.

Reproduce this grade

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.
