graded at commit 485beb8 · 2026-01-27
The skills/react-native-skills 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 “React Native and Expo best practices for building performant mobile apps. Use when building React Native components, optimizing list performance, implementing animations, or working with native modules. Triggers on tasks involving React Native, Expo, mobile performance, or…” — 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/react-native-skills?
- 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.
