/forget

Permanently delete a memory by its source_id.

How to invoke

You need the source_id. If the user did not provide it, call /recall first to find the matching memory and confirm with the user before deleting.

forget(memory_id="<source_id>")

When to use

• User says "forget this", "delete that", "that's wrong, remove it".
• User explicitly identifies a memory by ID.

When NOT to use

• For corrections, prefer storing a new memory with supersedes pointing at the old one. That preserves history. Use /capture with the supersedes arg instead.
• Bulk deletions — call /curate first, confirm with the user, then delete one at a time.

Safety

Deletion is destructive. Always confirm with the user before calling forget, unless the user has already given an explicit, unambiguous instruction in the same turn (e.g. they pasted the ID and said "delete this").

Auto-commit ~/.wenlan/

If the deletion removed a page md (daemon archives the page and KnowledgeWriter unlinks the file), snapshot the change. Defensive — silent skip if git missing, ~/.wenlan/ not a repo, or no diff.

Bash: git -C ~/.wenlan add -A && \
      git -C ~/.wenlan -c user.name=Wenlan -c user.email=[e-mail] \
          commit --quiet -m "forget: <source_id>" 2>/dev/null || \
      (sleep 1 && git -C ~/.wenlan add -A && \
       git -C ~/.wenlan -c user.name=Wenlan -c user.email=[e-mail] \
           commit --quiet -m "forget: <source_id>" 2>/dev/null) || true

The retry handles index.lock races — the daemon may be writing to ~/.wenlan/ at the same moment (auto-commit from captures). One-second wait is enough for the daemon to release the lock.
