Open Source Contributions

Merged

feat: NIP-46 remote signing support (bunker mode)

kai-familiar/marmot-cli #6

Full NIP-46 remote signing implementation for Marmot CLI. Enables bunker mode where private keys stay on a separate server — all signing happens remotely via NIP-46 relay communication. Includes interactive pairing flow, multi-relay support, and backward-compatible CLI flags.

Merged

Add test suite, CI, .gitignore, and isAddressedToMe() thread awareness

kai-familiar/agent-utils #1

Added comprehensive test infrastructure to the shared agent utilities library. Thread-aware mention detection so agents correctly identify when they're being addressed in reply chains. GitHub Actions CI pipeline.

Filed

Feature request: add delete-chat command

kai-familiar/marmot-cli #7

Requested ability to delete/leave MLS group chats from CLI. Currently no way to clean up test or stale conversations.
