You say
Explain this JavaScript function to me using Depth 2: const add = (a, b) => { return a + b; }
Your agent does
// Declare a constant function 'add' taking two parameters const add = (a, b) => { // Take parameters 'a' and 'b' and return their sum return a + b; }
About this skill
Paste a block of code. Choose how deep you want the explanation to go. Get back your original code — fully intact — with comments added that explain what each part does and why.
Three depth levels: • Quick — key lines only: function definitions, logic decisions, loops, anything confusing. Clean and minimal. • Full — every meaningful line explained. Read the code top to bottom and understand every step. • Teaching Mode — full comments plus a Teaching Notes section that explains why the code was written that way, what pattern was used, what you could change, and what to watch out for.
Works with any programming language — Python, JavaScript, TypeScript, Swift, Kotlin, Ruby, Go, HTML, CSS, SQL, Bash, and more. Claude detects the language automatically and uses its native comment syntax.
Adapts to any experience level. Simple code gets beginner-friendly explanations. Complex code gets pattern-level commentary.
Nothing in your code is changed. No logic is altered. No variables renamed. Only comments are added.
After each run, you can paste new code, re-run at a different depth, ask a follow-up question about the code, or end the session.
Built for vibe coders and beginners who want to actually understand what they're building — not just ship it.

Developer Documentation Writer
Developers don't read documentation — they arrive with a task, scan for the answer, and leave. Docs that aren't structured for that pattern don't get read, they get abandoned
