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
plansmith
A planning-focused iterative loop plugin for Claude Code. Progresses through structured phases - explore, draft, critique, revise - with validation at each step. Unlike single-pass planning, it forces fundamentally different work at each stage: the explore phase rejects plan headings, the critique phase rejects finalization attempts. This makes it structurally impossible to skip ahead, producing higher-quality implementation plans before writing any code.
Agent-Native Plan
Structured visual plans and PR recaps with diagrams, prototypes, annotations, and sharing
