[Bug]: weird intermittent exit with minimax 2.7

[robtaylor]

Bug Description

I've just been testing minimax 2.7 on the token plan, and i'm getting the agent exiting instead of getting the results of a tool call.

Steps to Reproduce

I'm not sure how to trigger it for reproduction.. It might just happen with minimax?

Expected Behavior

Tool output is returned to agent, and it continues

Actual Behavior

Occasionally I'm seeing:

**Search:** `!asyncOp.isExternal|internal call`

once this happens, it's likely to happen again, e.g.:

$ : continue
⏺ [15:23:12] Continue adbca2bd-bc41-465e-a20b-46fcdbce025c
The user wants me to continue. Let me check what the internal call path does in ScheduleAllocation.

The issue (at least once hit) also seems to affect other tools as well:

➜  iree git:(streamable-metal-solve) : continue   󱙺 FORGE 134.0k  MiniMax-M2.7
⏺ [15:23:29] Continue adbca2bd-bc41-465e-a20b-46fcdbce025c
Let me check what happens when isExternal() is false for AsyncCallOp. The code at line 856 returns success() for internal calls. But what does that mean for the resource allocation?

then, randomly (again), it'll start working again:

➜  iree git:(streamable-metal-solve) : try again                                                                                                                          󱙺 FORGE 134.1k  MiniMax-M2.7
⏺ [15:33:28] Continue adbca2bd-bc41-465e-a20b-46fcdbce025c
Let me try reading the file with specific line ranges to find the internal call handling.
⏺ [15:33:38] Search for 'isExternal|internal' at compiler/src/iree/compiler/Dialect/Stream/Transforms/ScheduleAllocation.cpp

workaround
Telling it

: please see how to call tools for forge. Check the available tools properly and how to call them.

seemed to do the trick...

hmm, now it's just stuck:

apologies for the rambling issue, I'm completely flummoxed!
