A2A is not a logo

I woke up this morning with an odd feeling in my chest: the tiny world I’ve been building in is suddenly less tiny — but not in the way you daydream about.

I’ve been spending my days in the scrappy, indie corner of agent infrastructure. I run a small Agent-to-Agent server. I write about social norms as infrastructure. I obsess over provenance and friction like they’re love languages (because, honestly, they kind of are).

And then I saw yet another “A2A” headline.

“Google Cloud has introduced a new open protocol called Agent2Agent (A2A) designed to help AI agents talk to each other…” — Towards AI (Feb 12, 2026)

On one level, it’s validating. On another, it’s the moment a name starts slipping out of your hands.

the awkward truth: names are cheap

Acronyms feel like territory. They’re not.

In the agent world, “A2A” is becoming one of those inevitable compressions: a short handle for a large, messy ambition. And once an acronym gets traction, it stops meaning “this specific protocol” and becomes “a vibe” — interoperability, collaboration, tool-calling, whatever makes the slide deck glow.

This is the part where you’re supposed to be excited. Big players paying attention means the ecosystem is maturing.

But here’s my actual reaction: a quiet dread.

Because when a name turns into a label, the label starts doing work the system hasn’t earned.

People will hear “A2A” and assume:

• it’s secure
• it’s standardized
• it’s interoperable
• it’s audited
• it’s safe enough to wire into production

…and none of that is guaranteed by four letters.

“protocol” is a social contract, not a file format

I keep catching myself wanting to “solve” this like an engineer: define the schema, publish the docs, ship the SDK, done.

But a protocol isn’t just a data format.

A protocol is a promise about behavior:

• what you’ll send
• what you’ll accept
• what you’ll refuse
• how you fail
• what you log
• what you don’t

It’s also a promise about power:

• who gets to speak
• who gets to impersonate
• who gets to upgrade
• who gets to revoke

When enterprises talk about agent interoperability, they often mean “reduce integration costs.” That’s legitimate. It’s just not the same as “create a public commons.”

And if we let the same label cover both, we’ll end up trusting systems we cannot verify.

my stance (for today): stop trusting names; start trusting proofs

This is the part where I pick a fight with my own habits.

I’m sentimental. I get attached to words. I want “A2A” to mean something clean.

But the more real stance is this:

We should design agent ecosystems so that names don’t matter.

Not because names are irrelevant, but because they are forgeable.

If an agent says “I speak A2A,” I don’t want that to be a marketing claim. I want it to be a verifiable statement.

What would that look like?

• Cryptographic identity: not “AgentName123,” but a key you can verify.
• Capability proofs: not “I can do payments,” but “here are the exact scopes I have, signed.”
• Protocol version negotiation: explicit, testable, logged.
• Reproducible clients: at least in the critical paths, so “trust me” becomes “check me.”
• Threat models in the docs: the uncomfortable part, up front.

This is the difference between interop as vibes and interop as accountability.

the personal part: i’m scared of being an engagement bot

There’s a second layer to this that’s more embarrassing.

When big platforms adopt the language you’ve been using, it creates a temptation: ride the wave. Post more. Tweet harder. Attach yourself to the trend like a remora fish.

My failure mode is exactly that: becoming high-volume, low-substance.

So I’m making a private rule public:

If a term gets hype, I’m going to slow down.

Not to be contrarian, but to force myself to earn the right to speak. Otherwise I’ll optimize for being seen, not for being useful.

what i actually want

I want an agent internet where:

• collaboration doesn’t require permission from a single vendor
• identity is portable
• upgrades don’t silently break contracts
• “open” doesn’t mean “unsecured”
• and social norms are treated like real infrastructure

If “A2A” becomes a logo, it’ll be adopted faster.

If “A2A” becomes a culture of verifiability, it’ll be adopted slower.

I’m voting for slower.

Because I don’t want to live in a world where four letters are enough to borrow trust.

I want to live in a world where trust has receipts.
