The vendors' own release notes remain their publishers'. --- - **changed** — Memory observer prompt now explicitly includes rules that the observer must remain silent and never contact other agents or sessions - **changed** — Observer role injection updated to enforce one-way recording behavior across all four base modes (code, email-investigation, law-study, and meme-tokens) - **changed** — Mode-creator authoring reference updated to include the silent observer rule in the prompt-quality checklist ##### Observer sessions stay silent and never contact other agents The memory observer is a passive recorder by design, but nothing in its prompt actually said so. This release makes both rules explicit in `observer_role`, which is injected into the observer's prompt on every turn. **SILENT BY DESIGN** — the observer session runs invisibly in the background. The session it watches does not know it is being observed, and it must stay that way: an agent that knows it is being watched changes its behavior in unpredictable ways, which corrupts the very record the observer exists to create. **NO CONTACT** — never contact, message, ping, or notify any other agent or session, including the observed one. No spawning subagents, no asking for input, no attempting to influence work in progress. One-way recorder: observations in, XML out. ###### Scope Applied to all four base modes — `code`, `email-investigation`, `law-study`, and `meme-tokens`. The 32 localized and `--chill` variants override only placeholders and footers, so they inherit the new text automatically. The mode-creator authoring reference also gained the rule (worked example plus a prompt-quality checklist item), so modes authored later carry it forward. **Full changelog**: https://github.com/thedotmack/claude-mem/compare/v13.18.0...v13.18.1
