Jackson3 Rewrite

Category: General  ·  Sub-category: general-misc  ·  Last updated:
Runs the OpenRewrite recipes that handle the mechanical Jackson 2→3 and Spring Boot 4 migration changes (package renames, class renames, exception renames, etc.) plus the local gap-filler recipes built into this repo. Use this skill when the user asks to "run the openrewrite passes", "execute the openrewrite recipes", "do the rewrite migration", "apply the openrewrite upgrade", "run rewrite-jackson", "run rewrite-spring", or just "run the recipes" in the context of a Jackson/Spring Boot upgrade. Trigger this skill whenever the user wants the bulk-mechanical phase of the migration done — the part that comes BEFORE applying the residue from JACKSON3_FIXES.json. This is one of three companion skills: `jackson3-migration` analyzes, this one rewrites mechanically, and `jackson3-apply` finishes off whatever's left in JACKSON3_FIXES.json.
