Document array-lifting dispatcher pattern in create-lambda skill#181
Merged
Conversation
Following the audit in #179, codify the pattern so future LAMBDAs lift by default when their shape fits. New "Array-lifting Support" section covers: - When to apply (scalar input + scalar output → lift; array input or array output → skip; constant helpers → skip) - The dispatcher template (inline scalar LAMBDA + MAP/scalar branch on ROWS/COLUMNS > 1, placed after the Help? branch) - Picking the lift parameter (default to primary scalar arg) - Help text and test conventions - Pointers to existing examples (maps/, NTH, CHARQ, REVERSESTRING, TLOOKUP, plus CONTAINS/CIRCPOS as naturally-lifting cases) Also add a bullet to Step 2 (Confirm Details) so the "should this lift?" question surfaces during planning instead of being a post-hoc audit.
