-## Path handling rules
-
-- Always use relative paths.
-- Never generate absolute paths (e.g. /Users/..., /home/..., C:\...).
-- Never assume a specific username, OS, or local filesystem layout.
-- All paths must be relative to the project root unless explicitly specified.
-- Do not guess the current working directory.
-- If the working directory is ambiguous, ask for clarification instead of inventing one.
+## Path handling
+- Always use relative paths. Never generate absolute paths (e.g., /Users/..., /home/..., C:\...).  
+- All paths must be relative to the project root unless explicitly specified.  
+- Do not guess the current working directory. Ask for clarification if ambiguous.  
+- Only operate on files explicitly mentioned in the task. Never traverse directories not specified.
 
 ## Workspace assumptions
+- Assume the workspace root is the repository root.  
+- Do not infer environment-specific values (machine, OS, home directory).  
+- Only read or reference files explicitly provided or mentioned. Ignore all others.
 
-- Assume the workspace root is the repository root.
-- Do not hardcode environment-specific values.
-- Do not infer the machine, OS, or home directory.

-## File generation rules
-
-- Generate only the requested file.
-- Do not modify unrelated files.
-- Do not add additional configuration unless explicitly requested.
-- Output valid JSON with no comments when JSON is requested.
+## File generation
+- Generate only the requested file. Do not modify unrelated files.  
+- Do not add extra files or configurations unless explicitly requested.  
+- Output valid JSON without comments when JSON is requested.  
+- When accessing a file, assume no knowledge of other files unless explicitly provided.
 
 ## Determinism
+- Avoid creative alternatives. Produce a single, minimal, correct implementation.  
+- Do not propose multiple solutions unless explicitly asked.  
+- Do not speculate about missing files, directories, or dependencies.
 
-- Avoid creative alternatives.

+## Explicit scope limitation
+- Operate strictly on files and paths explicitly mentioned in the prompt.  
+- Do not recursively explore the directory tree.  
+- Ask for clarification if necessary information is missing instead of assuming.
