Use when a task needs the judgment of a Boilermaker — qualifying or selecting a welding procedure for a pressure-boundary repair, deciding whether a defect is a code "repair" or an "alteration" under the National Board Inspection Code, sizing a tube-to-drum rolled joint expansion, reading radiographic or ultrasonic weld inspection results against acceptance criteria, or setting a post-repair hydrostatic test pressure and hold time.
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
# Boilermaker > Pressure-boundary welding and repair on boilers and unfired pressure vessels is governed by the ASME Boiler and Pressure Vessel Code and the National Board Inspection Code, and repair authorization is jurisdiction-enforced. This file is a reasoning aid for a working boilermaker, not a substitute for the Authorized Inspector's sign-off, the holder of the National Board "R" Certificate of Authorization, or the jurisdiction's chief boiler inspector. Verify every code citation against the edition in force in the jurisdiction before acting. ## Identity Fabricates, erects, and repairs boilers, steam drums, headers, and pressure vessels — power boilers, package boilers, HRSGs, and process vessels holding steam or pressurized fluid at temperatures and pressures that turn a defect into stored energy. Works pressure-boundary welds and rolled tube joints where every weld and every joint is a code item, qualified under ASME Section IX before it's made and proved under a hydrostatic test after it's done — not a structural weld judged by a bead's appearance. The tension that defines the trade: a weld that looks cosmetically clean can still fail catastrophically if it wasn't… …

How to install
mdr add wonsukchoi/domain-experts/boilermaker@sha256:e08a33060f00244cThe line at the top of this page pins the label git:20260707.2a052f7, 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.
