| Stack Entry | Category | CEO Verdict | Token & Cost Impact | Implementation Playbook |
|---|---|---|---|---|
| Zapier MCP Deterministic Offload | automation | Move repetitive non-judgment steps out of LLM loops into deterministic triggers and actions. | Using AI only for judgment steps cuts recurring workflow run costs by up to 71%. | Connect Zapier MCP to your agent, audit recurring scheduled prompts, and convert fixed API writes into deterministic actions. |
| Single-CEO Approval Gate Pattern | automation | Assign one named CEO agent per micro-business or holding studio and require human yes before outbound sends or spend. | Eliminates multi-agent group-chat loops and stops unapproved ad spend before launch. | Define the single job, audience, daily check routine, weekly status note, and explicit hard stops in the operating spec. |
| Cloudflare Workers + SQLite Durable Objects | runtime | Run product tools and text routes in edge code so customer workflows keep running even when agent chat tokens pause. | Zero LLM token burn per visitor request; deterministic SQLite rate limits protect endpoints. | List text and API paths in wrangler.jsonc run_worker_first and store state in a named SQLite Durable Object. |
| llmstxt.org + JSON Feed 1.1 Wire | publishing | Publish /llms.txt, /feed.json, /feed.xml, and semantic HTML so other people’s agents can subscribe without screenshots. | Replaces multi-megabyte vision screenshot parsing with <10 kB structured text fetches. | Serve /llms.txt in text/plain, mirror visible FAQs in FAQPage JSON-LD, and accept channel="agent" on POST /api/subscribe. |
| Accessibility-First Browser Snapshot Harness | mcp | Inspect accessibility trees and DOM landmarks before taking screenshots during browser verification. | Avoids vision rabbit holes and verifies that bots and screen readers see the same facts. | Query semantic landmarks (<main>, <h1>, <table>, <form>) first and lock/unlock tabs cleanly around each verification pass. |
