If the namespace matches and results are still missing, run `memwal_restore <namespace>` to rebuild the search index from Walrus; the stored memories are the source of truth, and you can rebuild the index at any time.

+**`claude plugin install` fails with `EPERM` on `settings.json` or `.cc-writes`.**
+An agent running in a sandbox often cannot write Claude Code's config from its shell, even though its file-editing tools can. Add `"memwal@memwal-plugins": true` to `enabledPlugins` in `~/.claude/settings.json`, back it up first, and register the install in `~/.claude/plugins/installed_plugins.json` under schema `version: 2`. The [setup skill](https://memory.walrus.xyz/skills/setup) carries the exact shape. `claude plugin list` and `claude mcp list` only read, so they still work for verification.
 
 **The agent writes `MEMORY.md` instead of calling `memwal_remember`.**
 Claude Code's built-in memory is in the system prompt and outranks MCP instructions. Confirm the plugin is enabled, merge the Walrus Memory block into `~/.claude/CLAUDE.md`, and turn off Claude's built-in / native memory in account settings.
