Cline: The model used search patterns that don't match anything in the file
The model used search patterns that don't match anything in the file. Retrying...Status: OpenLast verified 2 documented fixes3 sources
What it means
A replace_in_file edit failed because the SEARCH block the model produced did not exactly match the file content; Cline retries the edit.
Causes
- SEARCH blocks must match character for character including whitespace and indentation; models sometimes emit mismatched blocks.
- A contributor noted prompt engineering is tuned for the Sonnet family via Anthropic, OpenRouter or the Cline provider and differs for OpenAI-compatible endpoints.
How to fix it
- Fix 1.
Update Cline: 3.6.3 improved diff edit prompting to avoid reverting to write_to_file on non-matching search patterns; 3.54.0 "Prevent infinite retry loops when replace_in_file fails repeatedly."
- Fix 2.
Contributor suggestion in #4384: when using Sonnet models, use them through the Anthropic, OpenRouter or Cline provider rather than an OpenAI-compatible endpoint for better-tuned prompts.
