labscript

Generate prescription PDFs with e-signatures and QR verification.

A Rust CLI that turns structured prescription data into professional PDFs. Each document carries a digital signature and a QR code that anyone can scan to verify it has not been tampered with. Starts in about 2 milliseconds.

Why This Exists

Prescriptions are still written by hand or exported through clunky EMR interfaces. Neither fits into a modern clinical workflow.

labscript takes structured input -- a JSON file, stdin, or CLI flags -- and produces a clean, tamper-evident PDF. The QR code on each document encodes a SHA-256 hash of the prescription contents. Pharmacists or patients scan it to confirm nothing changed after signing.

One command. Deterministic output. No GUI, no cloud, no subscription.

Install

cargo install --git https://github.com/199-biotechnologies/labscript-cli

Requires Rust 1.70+. Builds to a single static binary.

Quick Start

From CLI flags:

labscript generate \
  --patient-name "Jane Doe" \
  --patient-dob "1985-03-15" \
  --prescriber-name "Dr. Boris Djordjevic" \
  --prescriber-credentials "MD" \
  --prescriber-license "MD-12345" \
  --drug "Metformin" \
  --strength "500mg" \
  --form "tablet" \
  --quantity 60 \
  --sig "Take one tablet twice daily with meals" \
  --refills 3 \
  --diagnosis "Type 2 Diabetes" \
  --signature ./signature.png \
  --output metformin-rx.pdf

From a JSON file:

labscript generate --file prescription.json --output rx.pdf

Piped from another tool:

cat prescription.json | labscript generate --stdin --output rx.pdf

Verify a prescription QR code:

labscript verify "labscript:v1:abc123..."

Output is JSON when piped, human-readable tables on a TTY. Force JSON with --json.

Features

PDF Generation

• Professional prescription layout with patient and prescriber details
• Drug name, strength, form, quantity, sig, refills, and diagnosis fields
• Custom prescription date or automatic dating

E-Signatures

• Embed a PNG signature image directly into the PDF
• Prescriber credentials and license number on every document

QR Verification

• Each PDF carries a QR code encoding a SHA-256 hash of the prescription content
• labscript verify checks any scanned QR string against the expected hash
• Tamper-evident: changing any field invalidates the QR

Input Flexibility

• CLI flags for scripting and one-off use
• JSON file input for batch workflows
• Stdin for piping from other tools in the suite

Agent-Friendly

• labscript agent-info exposes machine-readable capabilities
• JSON output mode for AI agent consumption
• Exit codes: 0 success, 1 error, 2 config, 3 parse failure

Part of the Longevity CLI Suite
