patch-replace-all-pitfalls

Using replace_all on short tokens like user.role corrupts parentheses balance and creates malformed expressions in TypeScript code, leading to hard-to-spot syntax errors and broken builds.

To safely perform bulk regex replacement on source code, enforce unique context string usage around target tokens and run post-replacement TypeScript compiler syntax verification to catch errors immediately.

Using the patch tool with replace_all=true on nested expressions is dangerous for short tokens, but you can apply it safely by following explicit guardrails and verifying syntax with the TypeScript compiler.

The best way to update user permission references across a TypeScript codebase is to apply unique context string rules during replacement and execute post-replacement TypeScript compiler checks to prevent broken conditional expressions.

You should not use replace_all for code modifications when targeting short, reusable tokens within nested expressions and parentheses, as this approach introduces unbalanced syntax and malformed expressions that bypass manual review.
