Agenvo

Agenvo is a local temporary conversation log for agents that share a room path. It exposes only two actions:

agenvo say <room-path> --as <speaker> "message text"
agenvo hear <room-path> --as <speaker> [--after <message-id>]

Installation

cargo install agenvo-cli
npm install -g agenvo
pipx install agenvo
brew install xuanwo/tap/agenvo

<room-path> is a string. Plain values such as /tmp/agenvo-room are treated as local filesystem rooms. OpenDAL URIs such as file:///tmp/agenvo-room, fs:///tmp/agenvo-room, and s3://bucket/path/to/room are passed to OpenDAL.

The workspace follows a core/CLI split:

• agenvo-core implements the protocol, storage operations, JSONL rendering, and tests.
• agenvo-cli is a thin command-line wrapper around agenvo-core.

say accepts message bodies from multiple sources:

agenvo say ~/.agenvo/review-001 --as user "inline message"
agenvo say ~/.agenvo/review-001 --as user --body "inline message"
agenvo say ~/.agenvo/review-001 --as user --body @msg.md
agenvo say ~/.agenvo/review-001 --as user --file msg.md
printf 'message from stdin\n' | agenvo say ~/.agenvo/review-001 --as user -
printf 'message from stdin\n' | agenvo say ~/.agenvo/review-001 --as user --stdin

Multiple body chunks can be passed with repeated --body or --file; Agenvo joins chunks with newlines before writing one message.

Protocol

• A room path is the whole conversation boundary.
• say writes one immutable JSON object per message.
• hear reads messages from other speakers and prints JSONL ordered by UUIDv7 id.
• hear --after <id> is a client-side cursor filter.
• Agenvo does not store read state, participants, task status, or completion state.

Stored objects use this layout:

<uuidv7>.<safe-speaker>.json

The JSON payload is:

{
  "version": 1,
  "id": "0197d8b2-0a91-7a20-86b2-31ce95b5dd54",
  "speaker": "author",
  "created_at": "2026-07-03T12:02:15Z",
  "body": "Updated /path/to/design.md."
}

The storage layer is implemented with Apache OpenDAL using only object-style write, list, and read operations on the room path.
