agent-vesper v0.20.54

Continuous update of the Agent Vesper ACP agent (same PR updated in place, per maintainer guidance).

Changes since v0.20.51

  • v0.20.53 — ACP slash-command catalog (ADR 0010 Tier C): 28-command oracle-parity advertisement, in-process execution, and streaming event-sink parity; client-declared MCP servers on session/new accepted (fixes Zed load failure with MCP servers configured).
  • v0.20.54 — Slash-command menu fix: available_commands_update is now sent AFTER the session/new response. Zed drops session/update notifications for sessions it has not registered yet, so the previous pre-response advertisement left the slash-command menu permanently empty. Registry archive URLs realigned to the release assets.

Install

Download the archive for your platform from the release assets (URLs in agents/agent-vesper/agent.json), extract, and run agent-vesper-acp. After upgrading, fully restart Zed (the agent server process persists across thread switches) and start a new thread; type / to see the 28 harness commands.
