Selection, context, and ranking method
18 of 28 coding agents have a confirmed yes for “In your editor”. 5 are qualified or tier-scoped, 5 are confirmed no, and 0 remain not established. Only confirmed yes answers appear in this set; an unknown is never treated as a negative.
This is not an arbitrary slice of coding agents. Among the ones with a confirmed yes for “In your editor”, 16 of 18 also answer yes on reviews code, against 2 of 10 across the rest of the category. Every figure is counted from the stored, sourced datasheet answers linked on each row.
Projected from the live listing datasheets using the tenant’s “Does it run inside an IDE or editor?” axis. Membership requires a sourced yes; partial and unknown answers are reported above but excluded from the ranking. Differences from the rest of the category are Fisher exact tests over 34 other datasheet axes, Holm-corrected. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
