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.

When understanding is deep enough, it synthesizes a structured strategic specification with capability groups, dependencies, priorities, risk assessments, and verifiable success conditions. Independent parallel reviewers (technical feasibility, scope alignment, dependency audit, format quality) catch issues before the spec is finalized. The output is a standalone markdown document you can hand to your team, feed to any AI coding tool, or use as a project brief. For teams using ido4 MCP, the strate
