feat(auth): add session rotation & token revoke#42

Openmain ← feature/auth-session-rotation

Code Review Enginebot

Analyzed 3 files • 128 additions, 14 deletions

1. Architectural Summary

The pull request correctly introduces session invalidation routines. Vector retrieval confirmed that the token generation aligns with the session storage schema defined in prisma/schema.prisma.

2. Security & Correctness Audit

Secrets Check: Passed

SQL Injection: None

Type Safety: Verified

3. Suggested Code Modification

In features/auth/server/session.ts:42, protect against concurrent token invalidation races:

- await prisma.session.delete( { where: { token } });

+ await prisma.session.deleteMany( { where: { token, expiresAt: { gt: new Date() } } });

Key Features

Engineered for speed, context, and code reliability

Traditional linters only inspect syntax. Code Review Engine inspects architecture, logic, edge-cases, and cross-file dependencies.

Context Engine

Codebase Vector Indexing

Repository AST files are parsed into semantic chunks and embedded into Pinecone, giving the AI full contextual comprehension of your entire codebase.

AST Parsing • Pinecone Vector

Real-Time CI

Instant Webhook Triggers

Runs automatically on every pull_request.opened and synchronize event. Zero slash commands, zero setup friction, instant feedback.

Sub-second • Automated Event

Review UX

Precise Inline Suggestions

Generates clean, syntax-highlighted code diff recommendations that developers can review, copy, or apply directly on GitHub.

Syntax Diffs • 1-Click Apply

Security Audit

Automated Security Audits

Catches potential security issues including exposed secrets, SQL injections, missing authorization checks, and unhandled promise rejections.

OWASP Top 10 • Secret Audits

Workflow

Up and running in less than two minutes

Connect your GitHub account, sync target repositories, and let the reviewer engine handle the rest.

STEP 01Repository Connection

Install GitHub App & Connect Repositories

Authorize the official Code Review Engine GitHub App on your personal account or organization with 1-click OAuth permissions. Select the target repositories you want automated reviews on with granular control.

1-Click GitHub App installation with zero manual webhooks

Support for personal accounts, public repos & private orgs

Granular repository toggle switches & branch targeting

Step 1: GitHub App Connection & Repository Selection

STEP 02Vector Embeddings

Deep Codebase Vector Indexing

Select repositories to index. The background ingestion worker decomposes files into semantic Abstract Syntax Tree (AST) chunks and embeds them into your dedicated Pinecone vector namespace.
