Decision Matrix Extractor Prompt: generate Markdown trade-off tables with sharp threshold rules.
Download the Decision Matrix Extractor JSON preset for Vezz me. Highlight technical comparisons, vendor specs, or debate threads to generate a Markdown trade-off table.
Best fit
Best for tech leads, architects, product managers, and founders writing ADRs, PRDs, and vendor comparisons.
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).
1. Highlighted on page (Web Architecture Guide — Server-Sent Events (SSE) vs WebSockets)
Server-Sent Events (SSE) run over standard HTTP/1.1 or HTTP/2 connections and support automatic reconnection via Last-Event-ID, but only allow unidirectional server-to-client text streaming. WebSockets upgrade the connection to a full-duplex framing protocol supporting binary and text frames in both directions, but require custom heartbeat/reconnect logic and stateful load-balancer routing.
Ctrl+Shift+X“Build a Markdown decision matrix with sharp threshold rules and 18-month dealbreakers.”
2. Vezz me on-screen answer overlay
| Dimension | Server-Sent Events (SSE) | WebSockets |
| :--- | :--- | :--- |
| **Directionality** | Unidirectional (Server -> Client) | Full-Duplex (Bidirectional) |
| **Proxy & Firewall Friendliness** | Native HTTP/2 (zero upgrade blocks) | Custom `Upgrade` (blocked on some L7 proxies) |
| **Reconnection** | Built-in (`Last-Event-ID`) | Manual (must code backoff + resync) |
| **Payload Format** | UTF-8 Text only | Binary (`ArrayBuffer`) + Text |
- **Choose SSE when**: Streaming LLM tokens, notifications, or live feeds where client actions happen <1/sec via normal `POST`.
- **Choose WebSockets when**: Building sub-50ms bidirectional apps (multiplayer games, collaborative canvas, raw audio).
- **18-Month Dealbreaker**: SSE fails if HTTP/2 is disabled (6-tab HTTP/1.1 limit); WebSockets hurt during stateful rolling deploys.
3. Suggested follow-up questions in thread
- “Add WebTransport (HTTP/3) as a third column in this table.”
- “How do AWS ALB idle timeouts affect SSE vs WebSockets?”

Vezz me Custom Prompt Preset
Decision Matrix Extractor
Explicitly forbids generic 'both have pros and cons, it depends' filler and forces concrete quantitative/architectural rules plus 18-month migration regrets.
Synthesize the selected text into an objective, high-signal Decision Matrix: 1) Markdown Trade-Off Table: compare the options across Primary Strength, Operational Complexity, Cost/Scaling Cliff, Lock-In Risk, and Worst Failure Mode, 2) Sharp Decision Rules (No 'It Depends'): write explicit threshold rules ('Choose [Option A] when [specific condition/volume]' and 'Choose [Option B] when [specific condition/volume]'), and 3) 18-Month Dealbreakers: state the #1 reason teams migrate *away* from each option 18 months later.Step-by-step workflow
How to run this workflow in place.
Highlight a technical comparison, doc page, or practitioner thread
Select the text discussing two or more approaches (or ask to compare the highlighted tool against a named alternative).
Copy the Markdown table directly into your ADR, PRD, or Notion doc
The output is formatted in clean GitHub-Flavored Markdown ready for engineering or product docs.

Why this approach works better than switching tabs.
Frequently asked questions
Common questions about trade-off & adr preset.
What if the highlighted page only talks about ONE tool?
If you highlight documentation for just one tool (e.g., Kafka), Vezz me will automatically compare it against its primary industry alternatives (e.g., RabbitMQ / SQS / Postgres queues) or whatever alternative you name.
Can I paste the Markdown output into GitHub PRs and Notion?
Yes—both Notion and GitHub render the Markdown table natively when pasted.
Is this preset included in the Master Pack?
Yes, download the Master Prompt Pack to import all 22 presets at once.
