precedent-search
An advisory: it explains, and blocks nothing, on a hunt for one distinctive name, which refs answers with verified sites.
What it catches
A hunt for one distinctive name, which refs answers with verified sites.
Why
A precedent hunt is a search for one distinctive name, and it is the search the graph answers best: refs lists verified sites, so you land on working code instead of assembling it from grep hits. Measured over 1,499 sessions: 42% of new files were preceded by one of these, 71% in subagent sessions, where only 12.9% reached for a magus verb at all.
Seeing it
A verdict names its rule in brackets, which is how you got here:
advise [precedent-search]: ...
magus describe rule precedent-search prints the same entry at a terminal, and
magus describe rules lists every rule this workspace enforces.
