Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
tdd-guard
Enforces Test-Driven Development by intercepting file operations in Claude Code. When Claude attempts to edit or write files, TDD Guard validates the changes against TDD principles — blocking operations that skip tests or over-implement, and explaining what needs to happen instead.
isitdone
Make a coding agent prove it: run the repo's real tests, typecheck and lint before it says done.
