What's Wrong?

Whenever i use claude code, i'm using 2.1.117. I'm getting Context limit reached, whenever i try compacting, i get: ❯ /compact ⎿ Error: Error during compaction: API Error: Extra usage is required for 1M context · run /extra-usage to enable, or /model to switch to standard context

If i run /context, this is my output: /context ⎿ Context Usage ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛀ ⛀ ⛀ Sonnet 4.6 ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ claude-sonnet-4-6 ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ 53.6k/200k tokens (27%) ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ Estimated usage by category ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ System prompt: 6.5k tokens (3.2%) ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ System tools: 7.8k tokens (3.9%) ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ Custom agents: 417 tokens (0.2%) ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ Memory files: 195 tokens (0.1%) ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ ⛁ Skills: 1.3k tokens (0.7%) ⛁ Messages: 2.4m tokens (1178.1%) ⛝ Autocompact buffer: 33k tokens (16.5%)

TL;DR

The issue can be mitigated by running the /extra-usage command to enable extra usage for the 1M context or switching to the standard context using the /model command.

Guidance

  • The error message indicates that the context limit has been reached, and the /compact command is not sufficient to resolve the issue.
  • Running the /context command provides a breakdown of the context usage, which shows that the "Messages" category is exceeding the context limit (1178.1%).
  • To resolve the issue, the user can try running the /extra-usage command to enable extra usage for the 1M context.
  • Alternatively, the user can switch to the standard context using the /model command to avoid the context limit issue.

Example

No code snippet is provided as the issue is related to the usage of the Claude Code tool and its commands.

Notes

The issue is reported as a regression, and the user is using the latest version of Claude Code (2.1.117). The problem occurs when the context usage reaches 27%, regardless of the model used (Opus 4.6 or Sonnet 4.6).

Recommendation

Apply the workaround by running the /extra-usage command to enable extra usage for the 1M context, as this is the most straightforward solution to mitigate the issue.
