cosmos3-codebase-nav skillA

cosmos3-codebase-nav is agent-read markdown (skill) from nvidia/cosmos-framework: Navigate the Cosmos3 package codebase to find where parameters, configs, defaults, scripts, and documentation live. Use when the user asks "where is X in cosmos3", "how do I find the config for Y", "where are the defaults", "where do I change a parameter", or any question about locating files, modules, or settings. Also use when the user opens or edits files and needs orientation..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add nvidia/cosmos-framework/cosmos3-codebase-nav@git:20260728.dcb3761
Exact content
mdr add nvidia/cosmos-framework/cosmos3-codebase-nav@sha256:6ac3af0eaa42bfd5

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
