pi-hemingway-output-readability-score

Shows Hemingway: Grade N in Pi's existing footer for the whole final assistant reply. No model calls, downloads, reports or text changes.

Use

Requires Pi 0.86.1+ and Node 24.2+. Install from npm:

pi install npm:pi-hemingway-output-readability-score

Or install from GitHub:

pi install git:github.com/xRyul/pi-hemingway-output-readability-score

Then run /reload in Pi. No build step or API key is needed.

For local development, symlink this directory into ~/.pi/agent/extensions/pi-hemingway-output-readability-score instead. Use only one installation method to avoid duplicate loading.

• Updates after the agent settles, not during streaming or tool rounds. Ignores thinking, tools and incomplete responses.
• Recomputes on reload/session changes/tree navigation; clears while generating.
• Uses Hemingway's document-grade formula and sentence rules. English readability estimate, not a correctness or meaning check.
• Basic Markdown flattening keeps code contents. Abbreviations, ASCII word counts and physical line breaks affect the grade; complex rendered Markdown can differ.
• Hides the score for uncountable or oversized output (over 1,000,000 characters). Custom footers must display Pi's extension statuses.

index.ts handles the footer; readability.ts calculates the score. Both use only the existing Pi host and Node standard library at runtime.

Check

npm test

One dependency-free test file checks representative grades and final-response footer behaviour. No SDK download, engine cache or model request is needed.
