+
+**Original Task**: Title: Build a DAO Treasury Reporting Ag...
+
+## Automated Delivery
+### Pull Request: feat: implement DAO Treasury Reporting Agent
+
+**Title:** feat: implement DAO Treasury Reporting Agent
+
+**Summary:**
+This PR introduces the `TreasuryReportingAgent`, an automated Python-based agent designed to query on-chain treasury contracts, calculate aggregate USD values via price oracles, categorize outgoing transactions to determine burn rate, and project the remaining runway. It outputs a formatted text report matching the protocol's governance standards.
+
+**Changes:**
+- `scripts/treasury_agent.py`: Core agent implementation utilizing `web3.py` for chain interaction.
+- `requirements.txt`: Appended necessary dependencies (`web3`, `requests`).
+
+**Risks & Mitigations:**
+- *Risk*: RPC rate limiting during deep transaction history parsing for spending analysis.
+- *Mitigation*: Implemented block pagination and an SQLite caching mechanism for historical transfers.
+- *Risk*: Price oracle failure for long-tail DAO assets.
+- *Mitigation*: Graceful fallback to last known values with a warning flag for stale/unpriced tokens.
+
+**Patch / Pseudo-Diff:**
