Project Recon: Zero-Dependency Repo Sizing

What this skill does

Quickly answers: how big is this repo and what's in it. Shell-only (POSIX find + wc or PowerShell), runs anywhere, no install needed.

Output Format

Emit exactly this JSON structure — no additional fields:

{
  "total_loc": <int>,
  "languages": { "<lang>": <loc>, ... },
  "top_level_dirs": <int>,
  "primary_language": "<lang with highest LOC>",
  "git": <bool>
}
