Scan session history, surface save-worthy moments, propose → confirm → write. Never fabricate — every proposal must cite a transcript turn.

Scope

Creates or revises memory files in the agent's memory directory. Does not delete, merge-stale, or audit existing files (that is memory-clean). Does not redact or sanitize (that is memory-sanitize).

Path resolution

SKILL_SCRIPTS="${MEMORY_UPDATE_SKILL_SCRIPTS:-$HOME/.claude/claude/skills/memory-update/scripts}"
MEMORY_DIR=$("$SKILL_SCRIPTS/resolve-paths.sh" memory_dir)
SESSION_HISTORY_GLOB=$("$SKILL_SCRIPTS/resolve-paths.sh" session_history_glob)

Abort on non-zero exit. Override MEMORY_UPDATE_SKILL_SCRIPTS if installed outside $HOME/.claude. Override MEMORY_DIR / SESSION_HISTORY_GLOB env vars to target a non-Claude-Code agent's layout.
