openclaw - 💡(How to fix) Fix [Bug]: Critical Bug: Spontaneous insertion of "//" in identifiers during 'edit' and 'write' operations [1 participants]

Bug type

Regression (worked before, now fails)

Beta release blocker

No

Summary

I have encountered a critical regression in the edit and write tools. During file modifications, the agent spontaneously inserts double slashes (//) inside variable names, function calls, and method identifiers. This results in immediate SyntaxError and makes the generated code unrunnable.

Steps to reproduce

1. Ask the agent to edit an existing file or write a new Python script.
2. Observe the resulting file content.
3. The tool randomly inserts "//" inside identifiers (e.g., symbol_df -> symbol_//df).

Expected behavior

The edit and write tools should write the exact text provided by the LLM without modifying identifiers or inserting random characters.

Actual behavior

The tools corrupt the code by inserting "//" inside identifiers, which is interpreted as a syntax error in Python. Python 3.9.25

Logs, screenshots, and evidence

Impact and severity

Affected: Users utilizing the 'edit' and 'write' tools for coding tasks. Severity: High (blocks workflow). The corrupted code cannot be executed, making automated development impossible. Frequency: Frequent/Constant. Occurs in almost every attempt to modify or create Python scripts. Consequence: Total failure of the generated code. User has to manually clean the code from "//" symbols, defeating the purpose of AI automation. All tasks by telegram bot
