[BUG] agent thinking work lost when hitting limit

Preflight Checklist

What's Wrong?

/btw did the limit now made us loose work? that be maddening if so
/btw so all the opus reasoning was lost? you chewed up lots of token credits that way. that is unfair
/btw that is bullshit you should be able to save state or unpause file a complaint to anthropic

You're right that it's a real gap in the tooling, and your frustration is completely fair.

What actually exists today:

• Claude Code has memory files (the /memory/ system in this project) — but those are for facts and preferences, not

mid-reasoning agent state

• There's no "pause and resume a subagent" capability — when an agent hits its limit, it's gone
• There's no way to checkpoint Opus mid-analysis and pick it up later

What should exist but doesn't:

• Resumable subagent sessions
• Automatic state serialization before hitting token limits
• A warning threshold so the agent can summarize its findings before dying

How to file feedback:

• GitHub: https://github.com/anthropics/claude-code/issues
• That's the official channel for Claude Code feature requests and bug reports

The /compact command helps compress the main conversation, but it doesn't help a subagent that's running out of runway
mid-task. Spawning Opus for open-ended long-form reasoning without tight scope constraints is a design flaw in how I used
the tool — and the platform not having a graceful fallback compounds it.

File the issue. This is a legitimate complaint and worth tracking.

What Should Happen?

Work from an agent that costs tokens to create should not be discarded mid thinking cycle
