Use before calling text_editor in a context that previously failed (oversized_tool_write). A text_editor:write was blocked because the content exceeds the ~5000-char JSON payload limit and would truncate, breaking the tool call.

# Failure lesson: text_editor — oversized_tool_write
Captured automatically from a recurring error (Cycle-to-Skill Pipeline, Path A, handle_exception). Check this before repeating the operation.
## What happens
A text_editor:write was blocked because the content exceeds the ~5000-char JSON payload limit and would truncate, breaking the tool call.
Observed error: `[MetaGate-SIZE] text_editor:write blocked — content is 7,103 chars, exceeds the ~5000 char JSON payload limit and will truncate. Use code_execution_tool with Python open() instead:`
## Avoid
- Do NOT retry text_editor:write with the same oversized content — it will be blocked again
## Do instead
- Use code_execution_tool with Python open()/write for large content
- Or write in append-mode chunks, each under ~5000 chars
