mesh-tools stands on mesh-sdk's published package: the build receives its exact version and installs it after the package.json install, so a release is a new argument and the cached layer cannot keep an older SDK; the planner orders the toolchain after the SDK, and every bundle after the toolchain (issue 211). esbuild, a development dependency, is what the builder bundles each TypeScript entrypoint and launcher into one file with.
node-tools
The node's tool runtime as a module (novox/hq ADR 0175, to-be 38 WP3). Assigned to a machine, it is one process the host runs from this bundle, as the operator's account: it serves every assigned module's tools and every held seat's verbs on the bus, and answers MCP on the machine's loopback — the console (design 34). The controller composes the process (which bundles to load, where the credential is, whose machine it is); this manifest says only what the machine must have for it: the interpreter, a place for the credential, the loopback port, and leave to call every tool.
The code is the mesh-tools package in this directory; the module at the repository root,
mesh-tools, builds the images TypeScript bundles are compiled in. See the repository README.
