module-boundary SKILL.md skillA
module-boundary from noeigenstate/agentrix is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add noeigenstate/agentrix/module-boundary@git:20261029.7401cc6Pins git:20261029.7401cc6 in mdr.lock. Pin the fingerprint instead.

Use before changing code in a module that has a BOUNDARY.md, before briefing a worker on one, and when adding or editing a BOUNDARY.md — the strict format, the limits, and how npm test enforces it (paths, interfaces, imports, invariants tied to tests, no exceptions).
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
# Module boundaries A module's `BOUNDARY.md` (in its main folder) says what the module owns, what others may use, what it may use, and what must always hold. It is executable: `tests/module-boundaries.test.cjs` checks every file against the code, so a boundary that drifts from the code fails `npm test`. Only the architect (Opus, the lead) edits a BOUNDARY.md; a worker that finds one wrong says so in its report. ## Format Exactly these sections, in this order, each a `##` heading, every entry one `- ` bullet line: ``` # Boundary: <module name> <one or two sentences: what the module is for> ## Owns - `<path glob>` repo-relative, `*` within a name, `**` across folders ## Interface - `<name>` (`<file>`) — <what it is for> ## May import - `<path glob>` outside Owns; `src/shared/**` style ## Invariants - <rule> — <why> — test: `<test file>` › "<test name>" ## Not ours - <responsibility> — <module that owns it> ``` Limits: Owns ≥ 1; Interface ≤ 12; May import ≤ 12; Invariants 1–8; Not ours ≤ 8. More than that means the module does too much: split it rather than grow the list. ## What the check enforces …

How to install
mdr add noeigenstate/agentrix/module-boundary@sha256:ba20437bb0f94881The line at the top of this page pins the label git:20261029.7401cc6, 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.
