project-brain skillA
project-brain is agent-read markdown (skill) from mendixlabs/mxcli: Project-specific knowledge mxcli cannot compute — the requirements and slices being built from (a spec, a prototype, a conversation), why a pattern was chosen here, what is still undecided, which marketplace version broke what. Use when starting from requirements that live outside git, before designing something that looks like it was decided before, when you have had to correct the same thing twice, and when an mxbuild error is resolved by something non-obvious..
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.
What the file says
# Project brain The brain holds what mxcli **cannot** compute about this project. Two halves: - **Decisions** — why a pattern was chosen here, which marketplace version broke what, what a recurring mxbuild error means in *this* app. - **Open questions** — what is *not* decided yet, so it is not silently forgotten and rediscovered expensively later. - **The plan** — the requirements being built from and the slices they are grouped into, when the source is a specification document, a prototype or a conversation rather than GitHub issues. The plan half matters because hours of work can otherwise leave no trace: a Word document and a chat transcript are not in git, so a session that resumes later has no idea what it was building towards, and neither does the next person. It lives in `docs/brain/`, is committed, and is reviewed in a pull request like any other change. ## The rule that makes it work **Anything mxcli can answer does not belong here.** Entities, microflows, pages, bindings, references, callers, dead assets — all queryable. A note that transcribes any of them is a note that will disagree with the project the moment …

How to install
mdr add mendixlabs/mxcli/project-brain@git:20260922.4954f84mdr add mendixlabs/mxcli/project-brain@sha256:34d0ab8565bddbdfPin 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.
