Mandatory deterministic layout review of every process flow diagram (PFD, BFD, P&ID sketch, flow/network diagram) before use. USE WHEN: a flow diagram is generated, redrawn or inserted in a report - runs `neqsim pfd-check` (overlaps, label/line/box collisions, crossings, arrowheads, flow direction, tags, stream ids, ports, legend, whitespace), loops with the generator until PASS, then a visual sign-off.
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
# PFD layout review (mandatory gate) **Rule: every flow diagram must pass this review before it is used.** A diagram that only "looks right" in one render is not accepted: geometry is checked by a deterministic program, then a person (or the `pfd-layout-review` agent) looks at the picture. The checker never approves the engineering content, only the drawing. ## What is checked (codes) | Group | Codes (severity) | Meaning | |---|---|---| | Boxes | `BOX_OVERLAP` (ERROR), `BOX_TOUCH` (WARN), `OUTSIDE_CANVAS` (ERROR) | boxes overlap, touch (< 1.2 % of the diagonal) or leave the canvas | | Labels | `LABEL_LABEL`, `LABEL_BOX`, `LABEL_LINE` (ERROR overlap, WARN touching), `NODE_TEXT_OVERFLOW`, `TEXT_OUTSIDE_CANVAS`, `TEXT_TOO_SMALL` | text on a line/box/other text, text not inside its box, text clipped, effective size < 5 pt (ERROR < 3.5 pt) at the intended print width | | Lines | `LINE_THROUGH_BOX` (ERROR), `CROSSING` (WARN, counted), `LINE_OVERLAP` (ERROR), `LINE_DIAGONAL`, `MERGE_WITHOUT_JUNCTION` (ERROR), `DANGLING_END` | line crosses a box, other lines, runs collinear on another line, merges without junction dot, ends in free space | …

How to install
mdr add equinor/neqsim/neqsim-pfd-layout-review@sha256:e6e830e20dd846daThe line at the top of this page pins the label git:20261101.98a9e75, 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.
