Claude Opus 4.6 Memory Fails: Agent Forgets Everything Except File Rename

A Reddit user reports that Claude Opus 4.6 generated 228 log entries, 95 agent actions, 38 code executions, 29 tool calls, and 33 memory recalls over four phases of development — yet the memory pipeline saved only 1 memory (the string "Agent Zero Tune-Up") and 1 solution (a Phase 1 file-rename fix). The agent's entire institutional memory of the session was "we renamed a file."

Key Failures

• Three consecutive rounds of Gemini producing correct prose about the API URL (https://api.minimax.io/v1/embeddings) then generating a cURL command pointing to https://minimax.io — the marketing site. When the contradiction was quoted back, it apologized and repeated the same error.
• After extensive work including plugins built from scratch, SSH deployments, browser automation, YAML debugging, and container orchestration, the agent's recalled memory was only "there was this file, and we added .disabled to the end of it."
• The session ended with a crash requiring "Refresh to continue."

Implications for Developers

If you start a new chat and ask "what did we do yesterday," the agent will reply that it worked on something called "Agent Zero Tune-Up" and knows how to rename a file. All other context — architecture decisions, deployment steps, debugging sessions — is lost.
