+"""CODEC Skill: Observer Recall — "what was I doing?"

+CODEC's observer daemon watches the active window, screen text (OCR), clipboard,

+read it — asking "what was I doing 20 minutes ago?" returned "I don't have an
+observer skill". The daemon now mirrors the buffer to ~/.codec/observer_buffer.json
+and this skill reads it, filters to the time window you ask about, and summarises.

+Understands windows like: "20 minutes ago", "the last hour", "5 min", "just now".
