The TUI banner reported fewer tools than the classic CLI for the same config (e.g. 32 vs 38) when an MCP server connected slowly. Root cause: the agent snapshots `agent.tools` once at build time and never re-reads the registry. `_make_agent` briefly joins the background MCP discovery thread (`wait_for_mcp_discovery`, ~0.75s) so fast servers land in that snapshot, but a server slower than the bound — common for an HTTP MCP server on first connect — lands *after* the agent is built. Its tools are then absent from both the agent (uncallable until `/reload-mcp`) and the banner for the whole session. The classic CLI doesn't hit this because it re-derives `get_tool_definitions()` at banner render time (which re-waits for discovery), so it picks the late tools up. Fix: after a fresh agent is built and its first `session.info` emitted, if discovery is still in flight, schedule an off-critical-path daemon that waits for it to finish, then rebuilds the tool snapshot and re-emits `session.info` — the same rebuild `/reload-mcp` performs, but automatic. Both the agent's callable tools and the banner count catch up. Cache safety: the rebuild runs only while the session is still pre-first-turn (`_user_turn_count`/`_api_call_count` both 0 → nothing cached to invalidate). Once the user has sent a message we leave the snapshot frozen rather than break the cached prompt prefix mid-conversation; late tools then require an explicit `/reload-mcp` (user-consented), exactly as today. No-op when discovery finished before the agent build, when the join times out, when the registry was unchanged, or when the session was swapped/closed while waiting. Adds entry.mcp_discovery_in_flight() / join_mcp_discovery() accessors and covers the matrix (added/none/post-turn/timeout/unchanged/replaced) with unit tests. |
