sema
emergent-wisdom/semaPlugin
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
Why this score
Popularity score: 59/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Nov 4, 2026 at commit 495e4655b2b4, first 300 source files (it's a large repo), with Cisco's open-source skill-scanner.
What its code does:
- Reads environment variables and sends network requests with them API clients do this to send your key to the service. Check which service it talks to.src/sema/server/api.py:351 and 2 more
- Reads environment variables, where API keys usually livescripts/apply_vocabulary_change.py:49, scripts/rebuild_vocabulary.py:91, scripts/verify_vocabulary_change.py:83 and 2 more
- Uses dependencies without a pinned version A later version of a dependency could change what runs.pyproject.toml:28 and 12 more
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
