Maintain Context Stability in Long Sessions Using /compress-fast
Prevent AI 'hallucinations' in long sessions by compressing context.
Use the `/compress-fast` command to optimize your active context window, ensuring the AI retains critical information without hitting token limits.
The Scenario
You've been debugging a complex system for an hour and the AI's responses are becoming slow or disconnected from the initial context.
Before & after
As conversations get long, the AI loses focus or hits limit windows. You have to start a new chat and manually summarize the previous progress, taking 10–15 minutes.
Run `/compress-fast` to instantly summarize the current context. This takes about 10 seconds and prevents the 'forgetting' effect in long conversations.
The Prompt
/compress-fast
The compression engine is specifically designed to handle long-running tasks without losing the critical context needed for coding.
