Muse Code is Meta’s terminal/CI coding agent: run `muse` interactively or `muse exec "…"` headless for scripts and pipelines—plans, edits, and validates with approvals and an OS sandbox from the first run. Pair with Muse Spark/Wonder via Meta Model API when you build your own harness; use Muse Code when you want the ready-made agent loop.
Show HN (Oct 17): RugSnare pins each MCP tool's {name, description, inputSchema} by canonicalized SHA-256 at install, then diffs upgrades across 24 popular servers (~3.6M weekly installs)—336 contract changes found; grades BREAKING/LOOSENED/EXPANDED/NOTATION/COSMETIC and exits 1 for CI. Apache-2.0, zero npm deps; OWASP MCP Security Cheat Sheet now recommends contract pinning.
