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
sema
Sema adds a content-addressed vocabulary of 452 cognitive patterns to Claude. Each pattern has a handle like StateLock#5602 — a SHA-256 hash of its definition — so two agents using the same handle are provably talking about the same thing. Any divergence in meaning produces a different hash, making silent misalignment impossible. Key features: - sema_search — semantic + keyword search across the pattern library • sema_resolve — full definition, mechanism, invariants, and dependency graph for any handle • sema_handshake — verify two agents share the exact same definition; halt on mismatch • sema_tree — browse the taxonomy (Physics / Mind / Society / Infrastructure) • sema_root — one-hash fingerprint of the whole vocabulary, for fast drift checks • sema_mint — add project-local patterns (survives pip upgrades) • sema pull — sync a project DB with upstream, auto-redirecting renamed handles
harness-boot
Multi-agent development harness for Claude Code. Your AI has speed; we give it direction — through living specs and focused specialist agents.
