Describe the bug
The Copilot CLI runtime forcefully revokes tool execution capability when remaining session credits drop below a conservative threshold (~100-150 credits), even though the session still has sufficient credit capacity (e.g., 57.1 AI credits remaining) to perform individual tool calls. The runtime injects Final model call for this session: do not call tools; summarize progress, state what remains, and stop, completely preventing final non-destructive operations (such as copying a file).
Affected version
Current Version: GitHub Copilot CLI 1.0.85
Steps to reproduce the behavior
Configure 1000 AI credits limit
Create session and reach 940 credits used
Try to do one tool call
Copilot keeping return summary session and prevent tool calling
Expected behavior
Tools should be executed until 999 ai credits reached
Additional context
model Gemini 3.8 Flash
