Proposed fix: [Agno] "Async tool X can't be used with synchronous agent.run() or agent.print_response(). Use agent.arun() ..." (async MCP tools / async functions)

Recommended action: Use await agent.arun(...) / agent.aprint_response(...) (e.g. inside asyncio.run), or provide sync tool implementations. Option: Use arun/aprint_response [evidence: official_recommended_action] Applies when: Async tools Steps: 1. asyncio.run(agent.aprint_respon

Proposed fix: [PyTorch MPS] NotImplementedError "The operator 'aten::X' is not currently implemented for the MPS device ... set the environment variable `PYTORCH_ENABLE_MPS_FALLBACK=1`"

Recommended action: Set PYTORCH_ENABLE_MPS_FALLBACK=1 in the environment before torch is imported (the variable is read when the MPS library registers its fallback), accept slower CPU execution for those ops, or upgrade torch for newer MPS coverage. Option: Enable CPU fallback

Proposed fix: [PyTorch] torch.OutOfMemoryError "CUDA out of memory. Tried to allocate X. GPU 0 has a total capacity of ... is reserved by PyTorch but unallocated" (local embeddings / model loading)

Recommended action: Reduce batch size (e.g. model.encode(batch_size=...)), use fp16/bf16 or quantized weights, free other GPU processes; when reserved-but-unallocated is large set PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True before the process starts. Option: Smaller batches

Proposed fix: [Redis Search 8.8] missing-index reply changed to "SEARCH_INDEX_NOT_FOUND Index not found: <name>" — code matching "no such index"/"Unknown index name" breaks

Recommended action: Use SearchIndex.exists() (RedisVL matches all known wordings) or match all three fragments; inspect e.__cause__ rather than the wrapper message that interpolates the index name. Option: Use exists() instead of message matching [evidence: official_recommended_a
