WalkthroughA new TypeScript file, Changes
Poem
Impact AnalysisIntroduction of new global variable and utility functionsℹ️ Low 🔄 Impacts behavior A new TypeScript file introduces a global variable and three utility functions ( Test the new functions to verify correct logging behavior, ensure the placeholder function does not cause issues when invoked, and confirm the global variable is accessible as expected. Validate that the logging and debugger statements behave as intended in development environments. 🔍 Related Files
Addition of static analysis rules for TypeScript code qualityℹ️ Low 🔄 Impacts behavior A new configuration file introduces static analysis rules that warn against certain TypeScript patterns, such as using Verify that the static analysis tool correctly flags the specified patterns and that warnings appear as expected during development or CI runs. Test integration with existing tooling and ensure no false positives or negatives. 🔍 Related Files

26-32:no-empty-functionmisses arrow functions and blocks with whitespace.A frequent escape hatch is:
const noop = () => {}or
function x() { /* */ }Those won’t be matched. Either add a second rule for arrow functions or loosen the body matcher to allow comments/whitespace.

🛠️ Refactor suggestion
no-any-type pattern is too specific – will miss several common cases.
The pattern only matches declarations with an explicit identifier wrapper, e.g. foo: any, but it will not flag:
- Function return types:
function f(): any { … } - Generic defaults:
type X = Array<any> as anycasts
Consider broadening the rule or adding companion rules so that the ban is comprehensive.

In sgconfig.yml around lines 12 to 13, the current pattern only matches explicit
identifier declarations with type 'any' and misses other common cases like
function return types, generic defaults, and 'as any' casts. Broaden the pattern
to cover these additional cases or add companion patterns to comprehensively ban
the use of 'any' in all relevant contexts.

🛠️ Refactor suggestion
Remove placeholder doNothing or document its intent.
Empty functions add dead code and are explicitly banned by the static-analysis rules you just introduced. If this is truly a no-op, delete it; otherwise add behaviour or at least a TODO.
🤖 Prompt for AI Agents
In main.ts at line 8, the empty function doNothing is considered dead code and
violates static-analysis rules. Remove the doNothing function entirely if it
serves no purpose, or if it is intended as a placeholder, add a comment or TODO
explaining its purpose and why it is empty.

Replace global var with a typed, immutable declaration.
var introduces function-scoped, hoisted globals and breaks block encapsulation. Use const (or let if mutation is required) and add an explicit type for clarity.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In main.ts at line 1, replace the global var declaration with a typed, immutable
declaration by changing var to const and adding an explicit type annotation for
foo, such as const foo: number = 123, to ensure block scoping and type clarity.

Multiple red flags: any, console.log, and a live debugger statement.
anydefeats type-safety; preferunknownor a generic.console.logshould be replaced with a proper logger or removed in production code.- Shipping code with an active
debuggerwill halt execution in dev-tools.

In main.ts around lines 3 to 6, replace the use of `any` with a safer type like
`unknown` or a generic type parameter to improve type safety. Remove the
`console.log` statement or replace it with a proper logging mechanism suitable
for production. Also, remove the active `debugger` statement to prevent
execution from halting in developer tools.

process repeats the earlier issues and leaks block scope.
- Two occurrences of
any varinstead ofconstconsole.log

In main.ts around lines 10 to 13, replace the use of 'any' with a more specific
type for the 'value' parameter, change 'var temp' to 'const temp' to avoid block
scope leakage, and remove or replace the 'console.log' statement with proper
logging or error handling as per project standards.
