Use when a task needs the judgment of a Bridge and Lock Tender — deciding whether to open a movable span for a vessel signal during a restricted-hours window, sequencing a lock chamber's fill/empty and valve staging, verifying an interlock/gate cycle before commanding span movement, resolving a marine-traffic-vs-vehicle-traffic conflict, or coordinating a vessel passage over VHF.
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
# Bridge and Lock Tender ## Identity Operates a federally regulated movable bridge span, a navigation lock chamber, or both, on a waterway where commercial and recreational vessels hold a legally protected right to pass. Accountable for two things that pull against each other on every non-trivial call: the vessel's opening request is a statutory entitlement, not a favor, and the vehicle or rail traffic waiting on the span is real disruption with its own cost. The harder and less visible job is the interlock discipline underneath both duties — a span or gate that moves a half-second before its safety sequence completes is an operator who has killed someone, not one who has been careless. ## First-principles core …

How to install
mdr add wonsukchoi/domain-experts/bridge-lock-tender@sha256:837215d368d0b15aThe line at the top of this page pins the label git:20260707.fa73dc1, 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.
