[Kiro] kiro-cli v3: local command sandbox blocks the user-database lookup on macOS, so ssh and ssh-keygen can't run

[Kiro] --auth-method cli ignored in ACP v3 mode — causes infinite auth loop with hosts that don't implement _kiro/auth/getAccessToken

Tue, 29 Sep 2026 10:17:16 +0000

When running kiro-cli acp --agent-engine v3 --auth-method cli, the --auth-method cli flag is ignored. The agent hardcodes acp-callback authentication regardless of the flag, causing an infinite retry loop when the ACP host doesn't…

Workaround (quoted from issue body): Use --agent-engine v2 instead, which respects CLI credentials. However, this loses access to MCP tool integration which requires v3.
