git-agent for TypeScript

Atomic conventional commits for TypeScript codebases

git-agent splits TypeScript changes across types, implementation, and tests into separate atomic commits, generating precise conventional messages that reflect your type-safe refactors and feature additions.

diff example

diff --git a/src/services/auth.ts b/src/services/auth.ts
index c2d4f1a..9e8b3c2 100644

-export function verifyToken(token: string): { userId: string } {
-  return verify(token, config.jwtSecret) as { userId: string };
+export interface TokenPayload {
+  userId: string;
+  iat: number;
+  exp: number;

+export function verifyToken(token: string): TokenPayload {
+  try {
+    return verify(token, config.jwtSecret) as TokenPayload;
+  } catch (err) {

 }

git-agent outputrefactor(auth): strengthen verifyToken return type and error handling

- export TokenPayload interface with iat/exp fields for downstream consumers
- wrap jsonwebtoken errors so callers receive domain-specific TokenExpiredError
- remove unsafe cast in favour of typed return signature

Eliminates the implicit any in callers that previously destructured the
return value without type guards; downstream middleware can now distinguish
expired tokens from malformed ones.

Why it works for TypeScript

Separates type definition changes from implementation changes into distinct commits
Recognizes tsconfig.json project structure for accurate scope inference
Works with NestJS, Express, and tRPC project layouts
Handles .d.ts declaration file changes independently

FAQ

Will git-agent split my TypeScript and JavaScript files into separate commits?

git-agent groups changes by logical concern, not file extension. If a .ts file and a .js file are part of the same feature, they stay in one commit.

Does git-agent understand TypeScript decorators and metadata?

git-agent sends the raw diff to the LLM, which understands decorator syntax. NestJS controller diffs and Angular component changes are handled correctly.

Can I configure scopes to match my TypeScript path aliases?

Yes. Run git-agent init and it will read your tsconfig paths to suggest scopes. You can then edit .git-agent/project.yml to fine-tune them.
