Stop paying for old chat history: a free BYOK VS Code AI agent that compresses long sessions

Long AI coding chats get expensive for a simple reason: every turn resends
the whole conversation, so turn 30 costs far more than turn 3.

I built CodeCook to fix that. It's a free, MIT-licensed VS Code extension
(disclosure: I'm the author).

What it does

• Summarizes older turns and bulky tool output so you stop paying for them again
• Keeps your plan intact across summaries
• Shows token and cost estimates per turn, with daily, weekly, or monthly spend caps
• Checkpoints every turn: review diffs, revert, or rewind
• BYOK: Gemini, OpenAI, Claude, Azure OpenAI, or Bedrock, with no markup

In one long session, a single turn went from about 800k to about 15k tokens.
That's a best case, not an average, so I'm testing real billed cost next.

I'd love feedback on what breaks or what's missing.
