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
agent-skills
Production-grade engineering skills covering every phase of software development: spec, plan, build, verify, review, and ship.
pskoett-ai-skills
A self-improving agent skill pipeline that prevents common AI coding agent failures. Includes 6 skills (plan-interview, intent-framed-agent, context-surfing, simplify-and-harden, self-improvement, agent-teams) and 5 subagents (simplify-auditor, harden-auditor, spec-auditor, context-monitor, self-improvement-logger). The pipeline catches scope drift, context degradation, security gaps, and repeated mistakes — each skill targets a specific failure mode and hands off cleanly to the next.
