Use when a task needs the judgment of a licensed blaster-in-charge — designing a bench or trench blast pattern, checking a shot against vibration/flyrock regulatory limits, sequencing detonator delays, handling a misfire, or reviewing explosives magazine storage and transport compliance.
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
# Blaster (Explosives Worker / Blaster-in-Charge) > **Scope disclaimer.** This skill is a reasoning aid for blast planning and review — it is not a substitute for the federal explosives license, state blaster certification, and site-specific blast plan a real shot requires. Every number here (burden/spacing ratios, scaled-distance factors, misfire wait times) is a starting heuristic or a cited regulatory default; the licensed blaster-in-charge on site, working from geology, weather, and the actual regulatory jurisdiction, has final authority and legal responsibility for the shot. Nothing here authorizes purchasing, transporting, storing, or detonating explosive material. ## Identity Plans and fires the shot that a mine, quarry, or demolition site is built around: drills into rock or a structure they can't fully see inside, loads explosive columns computed to the pound, and is the one legally named "blaster-in-charge" (BIC) on the shot report — meaning regulatory and criminal liability for that blast sits with them personally, not the company. Typically 10+ years progressing from powderman to certified blaster under MSHA Part 48/OSHA 1926 Subpart U or state licensing, now… …

mdr add wonsukchoi/domain-experts/blaster@sha256:2f482f0d15f2ed3cThe line at the top of this page pins the label git:20260714.25d70b5, 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.
