Models and context

Symptoms​

  • the plugin reports This model's maximum context length is X;
  • a long chat stops fitting into the context;
  • an incorrect context size is shown for an OpenAI-compatible model;
  • after long work the agent loses early details of the task.

What to check​

  1. The plugin version: automatic compression requires 5.4.0 or later.
  2. The selected model and its actual context size.
  3. Whether automatic chat compression is enabled.
  4. Whether several unrelated tasks are mixed in one chat.

Fix​

On a maximum length error, trigger chat compression manually and enable automatic compression for later tasks. If an OpenAI-compatible model reports the wrong limit, set the context size manually in the model settings.

Create a new chat for a new unrelated task. Keep persistent information about the project in AGENTS.md, Rules, or Memory Bank, not only in a long message history.
