quern-landmark-migration
quern-landmark-migration is a Migrations, upgrades & porting skill for AI agents, published by quern-dev in the quern repository on GitHub. Skillspace rates quern-landmark-migration D (55/100) and it passed the safety scan; the rating is based on static analysis only.
Migrate a Quern app knowledge base from the legacy `identify_by:` schema to the `landmarks:` schema (introduced April 2026 in PR #22). Use this skill whenever `load_landmarks` returns a non-empty `skipped[]` array with `legacy_format` entries, or when the user explicitly asks to migrate / upgrade a knowledge base to landmarks. Categorizes files by translation difficulty, batches the mechanical ones with a single consolidated diff, and defers files that need the live screen for re-authoring. Trigger on: load_landmarks response showing skipped legacy_format files, user mentions "migrate landmarks" / "migrate knowledge base" / "update KB to landmarks" / "upgrade screens to landmarks", or working in a `.quern/ knowledge/` directory whose screens use `identify_by:` not `landmarks:`.
