Hey. i am curious what is the reasoning behind instruction to do merging by itself vs running openspec archive?

    Both paths exist by design. openspec archive performs a deterministic structural merge of delta blocks (src/core/archive.ts). The archive/sync skill is intentionally agent-driven so the LLM can do partial merges — e.g. add one scenario to an existing requirement without re-emitting the whole block — and reconcile prose, which the structural CLI merge can't (see the note in src/core/templates/workflows/sync-specs.ts:16). Closing as answered.
