-GAIA RAG Agent – Course Final Project (full‑feature) 🛰️
+GAIA RAG Agent – Course Final Project (clean build) 🛰️
 ====================================================================
-This version folds in **all** improvements required for a competitive
-score (> 50 % with good APIs):
-
-1. **Official system‑prompt** ‑ identical to the paper; model ends with
-   `FINAL ANSWER:` and the agent stops on that token.
-2. **Extended step budget** – `max_iterations = 16`, `context_window =
-   8192`.
-3. **Page‑reader tool** – `web_open` lets the LLM open the first search
-   result and read full text (crucial for album counts, FAC pages…).
-4. **Excel/CSV analyser** – `table_sum` sums numeric columns in uploaded
-   spreadsheets (food‑sales question).
-5. **Light normaliser** – strips trailing punctuation, trims spaces, and
-   canonicalises comma‑separated lists before submission.
-6. **Fallback salvage** – if we *still* hit max‑iteration, we parse the
-   exception string and try to extract `FINAL ANSWER:` from it.
-7. Keeps human‑readable logs, UI blurb, token accounting.
-
-Requirements: `pandas`, `openpyxl`, `llama_index`. Whisper/ASR and chess
-handling are not included; they’re optional for 60 %+.
+This edition moves **all custom tools into `tools.py`** (keeping
+`app.py` focused on orchestration) while preserving every earlier fix:
+
+* Official GAIA system‑prompt and `FINAL ANSWER:` stop token.
+* 16‑step ReAct, 8 k context, deterministic LLM selection.
+* `web_open` and `table_sum` now come from `tools.py::CUSTOM_TOOLS`.
+* Lightweight answer normaliser and max‑iteration salvage remain.
+* Gradio OAuth UI, verbose logging, and pared‑down requirements.
