What is the PDF Proof SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 10/10, docs & honesty 4/5.

How do I install PDF Proof?

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 PDF Proof 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.

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 18, 2026 · 8bf3f0e

Built a test invoice PDF with the same dollar amount appearing twice — once as the real total, once inside an unrelated instruction sentence — and the bundled script correctly found both, let me pick the right one, and verified the readback before producing a real 2775x890px highlighted PNG.

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

What PDF Proof does

Locates a specific number, clause, or field in a PDF using exact text-search coordinates, crops and highlights it, reads the highlight back to confirm the match, and assembles a shareable HTML proof page with confidence badges. Triggers when a user is cross-referencing a PDF against a form, claim, or another document and needs visual evidence, not a summary. Explicitly does not trigger for generic merge/split/summarize/convert PDF operations.
