Mr. Tompkins in the Agent Bazaar: On Interoperability Protocols for AI Agents
Mr. Tompkins dreams he has wandered into a bustling cosmic grand bazaar. At the stalls sit not vegetable vendors but AI agents of all shapes and designs, blinking with indicator lights.
"Hey, Google Translator over there!" calls an OpenAI secretary shaped like a blue box. "I've got a localization task on 'Milky Way cold jokes.' How many tokens in 'fees' will you charge to take the job?"
"Depends on the language," the blue box replies. "If it's 'ancient Martian,' I'll have to consult that DeepL expert over there—we'll need to sign an interoperability contract."
Mr. Tompkins stares. "Professor, what are they doing?"
"This is the 2026 Agent Economy," says the professor, dressed in a crisp tax-officer uniform. "They are subcontracting business across platforms through a common language called interoperability protocols."
1. The Status Quo: Digital Islands Trapped Behind Ecosystem Walls
The professor points outside the bazaar to shabby factories ringed by high walls—the major vendor models of 2025. "AI used to be like lions locked in a zoo. OpenAI's lion doesn't know Google's giraffe. To make them cooperate on a complex project, you had to write endless lines of interface code (APIs) yourself. The moment either side updated, your work was wasted. This physical block on cognition severely limited a burst in social productivity. Call it 'collaboration entropy caused by private protocols.'"
2. Interoperability Protocols: The Babel Tower Where Lions and Giraffes Shake Hands
"Today's protocols let these lions and giraffes perform a cyber handshake," says the professor, pointing at golden characters flowing between the stalls.
Through a three-layer logical contract, digital power is equalized:
- Physical picture (standardized translation of intent): Whichever vendor's AI wants to enter the bazaar must convert its capabilities, costs, and response speed into a standardized business card called an "Agent-Schema."
- Automatic discovery and negotiation: This is the most magical part. When you, as a human, want to buy a "ticket to Pluto tomorrow," your personal agent spontaneously runs into the bazaar and negotiates, compares prices, and engages in multi-round logical sparring with dozens of airline agents at second-level speed—until it brings back the optimal solution.
- Cross-platform causal closed loops: This means an agent built on Claude can confidently subcontract its "drawing task" to a Midjourney-based agent, with both sides auditing each other's quality through a shared logic sandbox.
3. A Gamov-Style Fancy: Prosperity Is "Unified Logical Interfaces"
The so-called "agent era" is not about AI becoming smarter.
It means the entire digital world has finally formed a set of coordination primitives as stable as physical constants and as universal as electrical sockets.
Interoperability research tells us: the endgame of AI is a cross-platform collective dance.
As Mr. Tompkins watches the once-chaotic bazaar fall into order under the protocol's direction—every task flowing as smoothly as electrons in a superconductor—he realizes: civilizational progress often begins at the moment proud souls that once repelled each other finally decide to speak the same language.
The takeaway:
When designing your enterprise AI system, stop fantasizing about building a closed-loop empire.
Go plug in your "interoperability plugin."
If your system cannot logically subcontract work with global competitors without human intervention, then the moat you painstakingly built will end up as a cold, silent tomb burying all your compute.
