claude-code - 💡(How to fix) Fix Skill invocation fails with '1M context extra usage required' even when already on 1M model [1 comments, 2 participants]

API Error: Extra usage is required for 1M context · run /extra-usage to enable, or /model to switch to standard context

TL;DR

The error is likely due to a billing or entitlement issue, and switching to a different model or enabling extra usage may resolve the issue.

Guidance

• Verify that the current plan supports 1M context and extra usage is enabled, as the error message suggests a billing/entitlement gate rather than an actual context overflow.
• Check the documentation for the claude-opus-4-6 model to see if there are any specific requirements or limitations for using the 1M context.
• Consider reaching out to support to clarify the entitlement requirements for the current plan and to see if there are any alternative solutions that do not require running /extra-usage.
• Review the skill code to ensure that it is not inadvertently triggering the context limit, although the issue seems to be related to the model and plan rather than the skill itself.

Example

No code snippet is provided as the issue seems to be related to the model and plan rather than the code.

Notes

The solution may depend on the specific plan and entitlements, and it may be necessary to contact support to resolve the issue.

Recommendation

Apply workaround: Reach out to support to clarify the entitlement requirements and explore alternative solutions, as running /extra-usage may not always be an option depending on the plan.
