Fix turns left for a custom model

Goal: make “turns left” correct for a model crystl does not know.

crystl estimates a model’s context window from its name. For an unknown model it uses a small default, so “turns left” shows too few turns. Set the real size once:

crystl model context set glm-4.6 200000

Use the model ID your agent reports. The size is a whole number of tokens. It is free on every tier.

What you’ll see when it works

crystl prints Saved. glm-4.6 has a context window of 200,000 tokens. “Turns left” uses the new size the next time it updates.

To see your sizes, run crystl model context list. To go back to the estimate, run crystl model context remove glm-4.6.
