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
gh-skills-builder
Design, build, review, and publish GitHub Skills-style exercises with one coordinating agent and five Agent Skills for learner journeys, workflow-backed validation, and release readiness.
harness-scope
A Claude Code mod that turns global skills, agents, instruction files (CLAUDE.md and rules) and tools on or off per repo through named profiles. A repo picks a profile with a one-line .claude/harness-scope.json; repos without the file are unchanged. It only reads: no file writes, network requests, child processes or model calls.
How to run each
gh-skills-builder
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
