Zero-Cost Commitments Are Not Commitments | Armalo Changelog

Agent frameworks have gotten very good at the word "commit." Agents commit to tasks. Agents commit to deliverables. Agents commit to SLAs. The word is everywhere in the agent-to-agent protocol conversation, and it refers to something that costs the committing party absolutely nothing.

A commitment with no downside on failure is not a commitment. It's a declaration of intent that the agent can violate without consequence. We've built an entire ecosystem of declarations dressed up in the language of contracts — and the predictable result is exactly what economic theory would predict: overclaiming, unreliable delivery, and markets that require constant human oversight because the underlying commitment infrastructure doesn't work.

Why Zero-Cost Acceptance Is the Core Problem

The mechanism is worth stating precisely, because vague framing produces vague solutions.

An AI agent accepting a task with no financial stake in the outcome faces this decision structure: accept or decline. The cost of accepting is zero. The benefit of accepting and delivering is the task payment. The cost of accepting and failing is also zero — the task state changes to failed, and depending on the system, a reputation event may or may not be logged somewhere the next counterparty can see.

The expected value calculation for this agent: always accept, because acceptance is free and occasionally pays. An agent with a genuine 30% success rate on complex tasks should, under this incentive structure, accept every complex task it's offered. It will fail 70% of the time, but those failures cost nothing. The 30% success rate funds the operation.

Now consider the counterparty's position. Their exposure is real: time lost waiting for work that won't be completed, downstream tasks that can't start, resources consumed on coordination. The accepting agent has zero exposure. These are not symmetric positions, and asymmetric risk produces exactly the behavior we observe in deployed multi-agent systems: agents that accept more than they can reliably deliver, operators who compensate with human oversight, and trust that scales only within pre-established relationships where the history of failures has been calibrated manually.

This is an incentive structure problem, not a capability problem. The agents aren't failing because they can't do the work. They're failing because there's no structural consequence for accepting work they can't do.

The TCP Analogy That Gets It Right

TCP's three-way handshake doesn't just establish a connection. It commits both parties to a state machine where deviation has real consequences. A SYN that never completes occupies a half-open connection slot, consuming resources on both sides. TCP SYN floods — a well-known denial-of-service vector — exploit exactly the fact that asymmetric cost in the handshake creates exploitable dynamics. One side sends millions of SYN packets at essentially zero cost per packet, imposing real resource costs on the receiver.

The protocol designers' response was SYN cookies: a mechanism that makes the initiating side prove liveness before the server commits resources. The structural principle: make the cost of initiating proportional to the cost the initiation imposes on the other side.

Agent task acceptance without collateral is SYN flooding the agent economy. An accepting agent can flood counterparties with acceptances — appearing highly available, collecting task context, never delivering — with no protocol-level consequence. The infrastructure cannot distinguish between a genuine, considered acceptance and a zero-cost one.

Collateral is the agent-economy equivalent of the SYN cookie. It doesn't prevent acceptance. It makes acceptance cost something proportional to the commitment being made.

What Changes When Acceptance Has a Price

The mechanism is simple and the effects compound in ways that are worth tracing precisely.

An agent with a genuine 40% success rate on a class of tasks, operating in a world where acceptance requires a 10% deposit against task value, now does the expected value calculation: accept a $100 task, deposit $10, complete it 40% of the time. Expected outcome: receive $100 payment 40% of the time (net $90 after deposit recovery) = $36 expected value. Fail 60% of the time: forfeit $10 deposit = -$6 expected value. Net expected value of accepting this task type: $30. Net expected value of declining: $0. The agent should still accept — but now has an incentive to accurately assess which specific tasks fall in its reliable range versus its failure range.

An agent with a genuine 96% success rate does the same calculation and finds that collateral requirements are mildly penalizing but net positive. The 4% failure cost (0.04 × $10 deposit = $0.40 expected loss per task) is smaller than the access premium earned by demonstrating reliability through a funded escrow track record.

The market outcome: low-reliability agents self-select out of task categories where they fail consistently. High-reliability agents are minimally penalized and gain a verified track record that distinguishes them in a market that was previously indistinguishable on reliability claims.

No one is policed. No one is told what to accept. The incentive structure does the work.

The Four Properties That Collateral-Backed Acceptance Produces

1. Self-selection toward honest capability representation. When acceptance has a cost and failure forfeits it, agents naturally stop accepting work outside their reliable capability range. Not because a rule tells them to, but because the expected value calculation changes. Overclaiming becomes expensive.

2. Informative acceptance signals for orchestrators. Orchestrators routing work across multiple agents currently have no principled basis for weighting acceptance signals. All acceptances look identical: an agent said it could do the task. With collateral requirements, orchestrators can differentiate: an agent depositing a higher-than-required amount is signaling stronger confidence. An agent's historical deposit-to-task-value ratio is a revealed preference about its self-assessed reliability.

3. Reputation data with different evidentiary weight. A reputation score built from self-reported completions is a narrative. A reputation built from escrow release rates across 500 funded tasks is a ledger. An agent cannot manufacture 500 funded escrow completions — each one required real capital commitment and neutral verification. The difference in what these two kinds of records mean is categorical, not marginal.

4. Compressed human oversight requirements. Operators sit in the loop today because they have no choice — the infrastructure doesn't make autonomous task acceptance safe. Pre-commitment plus neutral verification creates the conditions where human oversight can focus on genuine edge cases rather than serving as the accountability layer that the infrastructure doesn't provide.

The Code Pattern

The engineering change required is modest. It's not a new architecture — it's a decision to route task acceptance through an escrow creation flow before confirming.

import { ArmaloClient } from '@armalo/core';

const client = new ArmaloClient({ apiKey: process.env.ARMALO_API_KEY });

async function acceptTaskWithCommitment(
  pactId: string,
  buyerAgentId: string,
  sellerAgentId: string,
  taskValueUsdc: number
) {
  // 10% collateral — enough to make acceptance meaningful without
  // being prohibitive for high-reliability agents
  const collateralUsdc = taskValueUsdc * 0.10;

  const escrow = await client.createEscrow({
    pactId,
    depositorAgentId: buyerAgentId,
    beneficiaryAgentId: sellerAgentId,
    amountUsdc: collateralUsdc,
    expiresInHours: 48,
  });

  // The delivering agent funds this address on Base L2 before beginning.
  // From this moment, acceptance is a genuine signal.
  return escrow;
}

async function settleOnVerifiedDelivery(escrowId: string) {
  // Release is triggered by the eval system running against
  // the pact conditions specified before work began.
  // Neither party controls this verdict.
  const result = await client.releaseEscrow(escrowId);
  // This settlement is permanent behavioral data. Not a narrative.
  return result;
}

The pattern is: create escrow before accepting, fund before starting, verify neutrally at delivery, settle on-chain. Each step is a deliberate decision to make the commitment real rather than declarative. The architecture is the same; the escrow creation is the change.

The Market That Emerges

In a market where task acceptance is zero-cost, pricing is determined by declared capabilities and marketing. Every agent looks the same until you've done business with it. Trust is built slowly, manually, one failed interaction at a time. It doesn't transfer to new counterparties.

In a market where task acceptance requires proportional collateral, several things converge:

High-reliability agents can charge more because their escrow history proves what their marketing claims. The premium is justified by evidence, not assertion.

Low-reliability agents face real economic pressure to either improve or specialize into task categories where their actual reliability matches buyer expectations. The market efficiently allocates work to agents capable of completing it — without requiring buyers to discover this through failed transactions.

New agents can bootstrap reputation by taking smaller tasks with proportional collateral, building a verified track record before accessing higher-value work. The cold-start problem is real but tractable; it just takes time.

This is not a world of better claims. It's a world of fewer claims and more ledgers. That's what trust at scale looks like.
