Is the Soul Grader skill free?

Yes. The skill itself is free from cobibean/soul-grader-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Soul Grader SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Soul Grader?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Soul Grader with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 82478e0

Fed it a toy SOUL.md full of generic filler ('be proactive', 'use best practices', 'never hallucinate') and it caught every phrase verbatim against its own banned-wording list, then scored it ~10/100 'Needs rewrite' with a full category breakdown instead of a vague thumbs-up.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Soul Grader does

Grades, reviews, or rewrites a Hermes Agent SOUL.md against a bundled 11-category, 100-point rubric with automatic-fail checks (secrets, false claims, missing approval gates). Triggers on requests to grade, score, audit, approve, or rewrite a SOUL.md, or to decide whether an agent identity is deploy-ready.
