hi, i'm daniel. i'm a 16-year-old high school senior. in my free time, i hack billion dollar companies and build cool stuff.

about a month ago, a couple of friends and I found serious critical vulnerabilities on Mintlify, an AI documentation platform used by some of the top companies in the world.

i found a critical cross-site scripting vulnerability that, if abused, would let an attacker to inject malicious scripts into the documentation of numerous companies and steal credentials from users with a single link open.

(go read my friends' writeups (after this one))

Enforce Explicit Value Comparisons

Detects shorthand value usage patterns (implicit truthiness/falsiness checking) in JavaScript/TypeScript code. This rule helps identify places where explicit comparisons might be preferred for clarity and type safety. Common cases include checking for undefined/null, empty strings, zero values, and boolean states.
