+### Visibility Scope (OpenClaw)
+
+Use explicit scope when logging a learning:
+
+- `scope: session` — applies to the current thread/session only.
+- `scope: agent` (default) — write to current workspace (`.learnings/*`, `AGENTS.md`, `TOOLS.md`, `SOUL.md`).
+- `scope: global` — make it visible across agents by writing to a shared path and syncing references.
+
+When user says phrases like **"all agents"**, **"global"**, **"全局"**, **"所有会话可见"**:
+
+1. Write canonical entry to a shared file (example: `~/.openclaw/skills/self-improving-agent/references/global-learnings.md`).
+2. Add/refresh a short pointer block in each agent's `AGENTS.md` (or equivalent workspace prompt file) that references the canonical global entry.
+3. Announce completion and affected agents.
