## 1. EndConversation deferred tool added, limited to sustained abuse or demos

System prompt · under “Context management”

A new line under Context management introduces EndConversation as a deferred tool. Claude may use it only for sustained user abuse aimed at the assistant or when the user explicitly asks to see it demonstrated, and it must first load the full guidance with ToolSearch("select:EndConversation"). The line appeared in only 1 of 23 captures, so it may be specific to one setup.

- Behind a feature flag
- +34 / -0 words
- Landed in 1 of 22 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 entry added to appended context in one capture

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

A single line reading "EndConversation" now appears in the appended skills and environment context. It landed in only 1 of 13 captures, so it is likely tied to one setup, and the diff shows no description of what it does.

- Behind a feature flag
- +1 / -0 words
