    hey Jason, just seeing this.

    Any mode you want can be implemented in minutes or hours as long as you have a board attached via the usb port and you are talking to the repo ai via claude code.

    However i think those modes might already be supported? I vaguely remember the agent vibe coding them in

    No, since it has a great design flaw. Look at the boards json the mandatory feature of PSRAM and type is completely missing. Without a great rework taking this correctly in account no PSRAM is working for any espressif MCU.

    "great design flaw"

    "completely missing"

    "Without a great rework"

    If you are convinced this is a great undertaking then may I suggest you check out my custom coding agent clud with its built in ralph loop.

    clud loop "design out a test that relies on psram for esp32s3, test it against the attached board. Verify that it fails and then investigate and figure out the idiomatic way to have a data driven representation of psram for this board. Apply this fix then recruit an auditor to make sure the implementing agent didn't cheat and do shortcuts"
