Walkthrough

Removed the second locals_dict = locals() reinitialisation from the generated MCP tool schema function; the function continues to use the prior captured locals_dict for parameter collection, eliminating the redundant snapshot that could drift from earlier checks.

Title check ⚠️ Warning The PR title claims to remove a duplicate line, but the actual change introduces a bug by removing a necessary locals_dict reinitialization that causes a NameError at runtime. Clarify the title to accurately reflect the change, such as 'Removed locals_dict reinitialization in function builder', and verify the removal doesn't break parameter collection logic.

Walkthrough

The locals_dict reinitialization line was removed from the generated MCP tool schema function code. This previously refreshed the local-variables snapshot after building the parameters dictionary. The subsequent loop iterating over parameter names now references an undefined variable, introducing a potential runtime error.

Incorrect assessment:

The subsequent loop iterating over parameter names now references an undefined variable, introducing a potential runtime error.

  • The first locals_dict = locals() (at line 338) is still there - it remains in scope for both loops.
  • Between the validation loop and the params-building loop, no parameters change
  • No new locals are created - so refresh not required

@peteski22, you're absolutely correct, and I apologize for the incorrect assessment in the summary.

Looking at the code, I can confirm:

  • The first locals_dict = locals() at line 338 is indeed still present
  • It remains in scope for both the validation loop and the params-building loop
  • No new local variables are created between these two loops
  • The removed line was a duplicate reinitialization that was unnecessary

Your PR correctly removes redundant code. The duplicate locals_dict = locals() served no purpose since the original assignment captures all the function parameters, and nothing changes between the two loops that would require refreshing the snapshot.

I'll regenerate the summary to reflect the accurate assessment.
