project-brain from mendixlabs/mxcli is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mendixlabs/mxcli/project-brain@git:20261010.50fe33aPins git:20261010.50fe33a in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- skill-index: generated by scripts/skill-index.py; make check-skill-index --> ## Find it fast `sed -n '<from>,<to>p' SKILL.md` one section rather than reading the file; `./mxcli syntax <topic>` answers *how do I write this* for a fraction of either. | lines | section | |---|---| | 49-66 | The rule that makes it work | | 67-103 | Reading it | | 104-124 | Writing to it | | 125-204 | Recording requirements and slices | | 205-219 | When to capture a decision | | 220-254 | Recording what is NOT decided | | 255-274 | Write the anchor, not the name | | 275-296 | Checking it | | 297-312 | Size | | 313-329 | Commands | | 330-344 | Renaming | | 345-354 | What not to record | | 355-380 | Handing a slice to another agent | | 381-383 | Project brain (`mxcli brain init/capture/staged/promote/drop/check/show`) | <!-- /skill-index --> # 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. …

How to install
mdr add mendixlabs/mxcli/project-brain@sha256:6b13a130d4897865The line at the top of this page pins the label git:20261010.50fe33a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
