Date: 2025-12-06 Priority: P2 (Should fix soon)
Issue 1: PubMed JSON Parsing Crash
Status: SPEC-20 CREATED
File: src/tools/pubmed.py:88
The PubMed search tool crashes when the API returns non-JSON responses (maintenance pages, error pages). The JSON parsing happens outside the try/except block.
Resolution: See SPEC-20: PubMed JSON Parsing Fix
Issue 2: HuggingFace Client Missing Retry Logic
Status: SPEC-21 CREATED
File: src/clients/huggingface.py
The HuggingFaceChatClient has no retry logic for transient errors (429 rate limits, 500 server errors). When the API returns a 429, the entire research workflow crashes.
Resolution: See SPEC-21: Middleware Architecture Refactor
Issue 3: Misleading Middleware Folder Name
Status: SPEC-21 CREATED
File: src/middleware/
The src/middleware/ folder contains SubIterationMiddleware, which is actually a workflow pattern (team→judge loop), not interceptor middleware. This is confusing and misleading.
Resolution: See SPEC-21: Middleware Architecture Refactor
