ChatGPT SidePanel Dev Agent — Chrome Extension (MV3)

Version 0.1.2

What's new

• No eager HTML push → prevents 128k context overflows.
• Per-turn chunk quota (default 2) → model can fetch more in the next turn.
• Heuristic history trimming to reduce token usage.
• New tools: getDigest, getHtmlBySelector, getTextBySelector.
• Watch mode (SPA/DOM changes): resnapshots meta/digest after route changes or big DOM mutations.

Install

1. chrome://extensions → Developer mode → Load unpacked → select this folder.
2. Open the Side Panel from the toolbar button.

Use

• Click Snapshot DOM → sends META + DIGEST (no full HTML).
• Ask ChatGPT for actions; it will request getSourceChunk or selector-based tools as needed.
• Toggle Watch: On to auto-resume on URL/DOM changes (SPAs).

Tips to avoid overflows

• Keep conversations focused; long unrelated chat increases tokens.
• Let the model fetch small, relevant windows (selectors) instead of whole-page chunks.
• Increase chunk quota carefully if needed (sidepanel.js → MAX_CHUNKS_THIS_TURN).
