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
context-engineering
Context engineering for AI agents — AI-optimized second-brain skills, durable pipeline state for multi-agent handoffs, and expert prompt building.
adaptive-agent
Make your AI agent get stronger with use. Includes two skills: /skill-review (periodic audit of all skills for staleness, missing gotchas, and improvements) and /build-user-profile (build user profile from workspace context so the agent knows who you are). Also includes CLAUDE.md behavioral rules for skill self-improvement on friction, memory-to-skill feedback loops, and automatic skill gap detection. Inspired by Hermes Agent's four-layer memory architecture.
