AI Analysis

○Pass

Scrapes HN Firebase API to augment UI — solves a micro-problem no one asked for.

Strengths

•Caches user data per-page to avoid redundant API calls; respects HN's Firebase endpoints.
•Lightweight, no dependencies, zero setup friction beyond installing Tampermonkey.

Weaknesses

•Extremely narrow use case; only solves a cosmetic problem for a tiny fraction of HN users.
•Opus 4.6-written and 'messy' — author's own admission suggests it's not production-grade; likely fragile to HN layout changes.

Post Description

Small script to display account age/karma next to all usernames, so you have that info available to you without clicking through to someone's profile. Opus 4.6 written, it's a mess but it works :) Using with Tampermonkey on Firefox.
