This context is transferred securely as a distinct system preamble, completely separately from the user's prompt text, avoiding stealth concatenation. Sensitive variables, tokens, API keys, and credentials are automatically stripped/redacted from the transferred context payload before sending. - **Host Attribution**: Every response bubble, tool card, and thinking trace displays its originating host badge (e.g. `[Office PC]`, `[Linux Server]`). - **Non-Blocking Host Switching**: If Host #1 is executing a long tool or computation and you switch to Host #2, Host #1 completes its work in the background and commits results into the shared timeline. diff --git a/agents/antigravity/done/TASK-2026-08-24-06-auth-and-secrets.md b/agents/antigravity/done/TASK-2026-08-24-06-auth-and-secrets.md new file mode 100644 index 0000000..ff01fdd --- /dev/null +++ b/agents/antigravity/done/TASK-2026-08-24-06-auth-and-secrets.md @@ -0,0 +1,49 @@ +## Кодер 2 (review + доработка + пункт 7) + +### Ревью по §Anti-checklist (пункты 1–11): +1.
