## 1. EndConversation deferred-tool guidance removed

System prompt · under “Context management”

The system prompt no longer mentions the deferred EndConversation tool. It previously said to use it only for sustained user abuse aimed at the assistant or when the user explicitly asked for a demonstration, and to load its full guidance via ToolSearch first. This appeared in only 1 of 23 captures, so it likely applies to one specific setup.

- Behind a feature flag
- +0 / -34 words
- Landed in 1 of 23 prompts (main prompt 1/6)

```diff
-EndConversation (deferred tool): use only for sustained user abuse directed at the assistant, or when the user explicitly asks to see it demonstrated. Load the full guidance via ToolSearch("select:EndConversation") before using it.
```

## 2. EndConversation dropped from appended tool listing

Appended context (skills, environment) · at “EndConversation”

The name EndConversation was removed from the appended context, so it is no longer listed there as an available deferred tool. This was seen in only 1 of 23 captures and matches the removal of the EndConversation guidance from the system prompt.
