Subagent interrupted due to missing payment method - unclear error message

[zhangxaochen]

Description

Subagents (e.g., Sisyphus-Junior) are being interrupted when workspace lacks a payment method, but the error message is confusing and appears to be a system error rather than a user-friendly message.

Error Details

• Error Message: "No payment method. Add a payment method here: https://opencode.ai/workspace/wrk_XXX/billing"
• Worker: Sisyphus-Junior (glm-5 model)
• Status: interrupted

Expected Behavior

When a workspace doesn't have a payment method configured:

1. The error should be more user-friendly and explain that this is a billing configuration issue
2. Users should be guided to add payment method before starting resource-intensive operations
3. Perhaps show a warning BEFORE the subagent starts executing, not after interruption

Actual Behavior

• Subagent starts executing (appears to use resources)
• Gets interrupted mid-operation with a billing error
• Error message looks like a system/debug error rather than a user-facing message
• No clear way to prevent this from happening proactively

Suggested Improvements

1. Pre-flight check: Validate payment method availability before starting subagent tasks
2. Better error messaging: Make it clear this is a billing issue, not a system error
3. Warning system: Notify users when payment method is missing when they try to start subagent tasks
4. Retry mechanism: Once payment is added, allow easy retry without re-entering the entire prompt

Environment

• Platform: opencode.ai
• Worker: Sisyphus-Junior
• Model: glm-5
