JSON Parse error: Expected '}' with the write tool after updating to v0.5.5 Description #2002

Since updating to OpenCode version 0.5.5, I am encountering a persistent error when the agent attempts to use the write tool. The operation consistently fails with a JSON parsing error.

Error message:

Write

The arguments provided to the tool are invalid: Invalid input for tool write: JSON parsing
failed: Text: {"filePath":
"/Users/M***/*****.md".
Error message: JSON Parse error: Expected '}'

As shown the filePath string being passed to the write tool appears to be truncated. This results in an incomplete and malformed JSON object, which lacks the closing double quote for the file path and the final closing curly brace }. This malformed JSON is causing the JSON Parse error.
This issue seems to be a regression introduced in version 0.5.5, as this functionality was working correctly in previous versions. This bug is critical as it prevents the agent from creating or modifying files.

Steps to Reproduce

• Update to OpenCode version 0.5.5.
• Assign a task that requires the agent to write to a file with a relatively long file path.
• Observe the write tool failing with the "JSON Parse error: Expected '}'" message.

Expected Behavior
The write tool should receive a complete and valid JSON object, allowing it to successfully write to the specified file.
