The hermesone skill is graded A by polygraph under litmus-skill-v2, as of 2026-06-25, anchored to its content hash.

Self-reported Install, update, and manage the Hermes One desktop app via the `hermesone` npm package. Use when a user wants to set up Hermes One, install or upgrade it from the command line, check the installed version, preview a release before installing, pin a specific version, or drive…” — 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.

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.

Questions

What does the A skill grade mean for hermesone?
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.
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.
