Persona Guide — Tech Leads & EMs

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.

On-screen walkthrough

How this looks on a real webpage.

Instead of switching tabs and rebuilding context, highlight the exact passage that slowed you down and press your shortcut (default: Ctrl+Shift+X or Cmd+Shift+X on macOS, fully customizable in settings).

Context: Detailed
1. Highlighted on page (Engineering RFC — Cross-Service Event Architecture Proposal)
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).
Ctrl+Shift+X“Review this proposal from a Tech Lead perspective: what are the operational risks with fixed-delay retries and 100ms polling?”
2. Vezz me on-screen answer overlay

**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.

3. Suggested follow-up questions in thread
  • “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

How to run this workflow in place.

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.

Key details

Why this approach works better than switching tabs.

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

Frequently asked questions

Common questions about persona guide — tech leads & ems.

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?
