# AI Chrome extension for engineering managers & tech leads: review PRs, RFCs, and SRE postmortems.

Review pull request diffs, engineering RFCs, cloud pricing models, and incident postmortems in Chrome or Firefox with Ctrl+Shift+X.

> **Best fit:** Best for engineering managers, tech leads, and staff engineers context-switching between code reviews, architecture docs, and hiring/roadmap materials.

## Live Webpage Walkthrough

- **Source:** Engineering RFC — Cross-Service Event Architecture Proposal (`notion.so/eng/proposals/event-bus-migration`)
- **Recommended Context Mode:** Detailed

**Highlighted Passage:**
> Proposal: All state-changing microservices will publish domain events to an Amazon SNS topic, which fans out to individual team SQS queues. Services will implement optimistic locking on their primary Postgres tables and poll SQS every 100ms. If processing fails, messages are retried up to 10 times with a 1-second fixed delay before going to a Dead Letter Queue (DLQ).

**User Question (Shortcut):** "Review this proposal from a Tech Lead perspective: what are the operational risks with fixed-delay retries and 100ms polling?"

**Vezz me On-Screen Answer:**
**3 Staff/Lead Engineering Red Flags**:
1. **Fixed 1-Second Retries = Retry Storm**: Retrying 10 times with a fixed 1-second delay during a downstream database brownout synchronizes all retry traffic, guaranteeing that the database stays down. **Require exponential backoff with jitter**.
2. **100ms Short-Polling AWS Bill**: Polling SQS every 100ms across multiple service replicas incurs millions of empty API calls, inflating AWS costs. **Switch to SQS Long Polling (`WaitTimeSeconds: 20`)**.
3. **Missing Idempotency**: SQS has 'at-least-once' delivery; the RFC does not specify a deduplication store (e.g., Redis or transactional outbox) for message processing.

**Suggested Follow-Ups:**
- "Write a constructive RFC comment summarizing these 3 points for the author."
- "How should the team monitor the Dead Letter Queue (DLQ) in Datadog?"

## Step-by-step workflow

1. **Import the RFC Critic, Senior Reviewer, and Postmortem presets**: Equip Vezz me with our 1-click JSON presets for architectural stress-testing, code reviews, and blameless 5-Whys postmortems.
2. **Highlight architecture proposals, PR diffs, or outage reports**: Select the text in Notion, Google Docs, GitHub, or Jira and press Ctrl+Shift+X.
3. **Leave constructive, high-signal engineering feedback**: Use the generated findings to coach junior developers, strengthen RFCs, and prevent scaling failures before code ships.

## Context-switch between 10 engineering domains with confidence

Tech leads and engineering managers must evaluate database migrations at 10 AM, AWS NAT Gateway pricing at 12 PM, and a TypeScript generic type error at 2 PM.

- Spots distributed systems anti-patterns (retry storms, dual-write divergence, unindexed SQL queries)
- Translates complex technical trade-offs into business and financial risks for leadership updates
- Leaves the browser completely bloat-free: zero persistent overlays or background CPU hogging

## Tech Lead Browser Workflows

Comparing in-page AI auditing with manual review.

| Review Task | With Vezz me (Ctrl+Shift+X) | Manual Review Process |
| --- | --- | --- |
| Stress-testing an architecture RFC | 10 seconds (flags retry storms, missing outbox, scaling cliffs) | Spending an hour cross-referencing distributed systems literature |
| Auditing a 30-line regex or SQL query in a PR | Instant ReDoS check and NULL-trap edge cases | Mental dry-running or opening a separate REPL |
| Synthesizing an SRE outage postmortem | Extracts blameless 5-Whys causal chain in seconds | Manually untangling 4,000 words of chronological server telemetry |

## Frequently asked questions

### Is Vezz me safe to use on private GitHub enterprise repositories and internal RFCs?

Yes! Vezz me uses activeTab only—it has zero persistent background content scripts and never accesses your repositories or docs unless you highlight text and press Ctrl+Shift+X.

### Can I customize the coding style and architectural guidelines in Vezz me?

Yes! You can edit any imported preset (like Senior Engineer Code Reviewer) to include your team's specific stack rules (e.g., 'we use pnpm, Next.js App Router, Prisma, and avoid any').

### Where can I read our Software Developers workflow guide?
