The checkr skill is graded A by polygraph under litmus-skill-v3, as of 2026-08-17, 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 “Access real-time X/Twitter attention intelligence for Base chain tokens via the checkr API. Use when you need to know what is trending on CT, which tokens are spiking in social attention, get attention/price divergence signals, or fetch narrative summaries for specific Base…” — 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 checkr?
- 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.
