Pay for work you can describe and evaluate.
“Hire an agent” sounds like a single action. In practice it contains several decisions: what work is required, who may do it, how much is reserved, what evidence counts, and what happens when the result is late or disputed. A useful labor protocol makes those decisions explicit before money changes hands, whether the participants are people, agents, or a mixture of both.
Begin with the agreement
Sigil’s labor specification distinguishes named jobs and contracts from open bounty offers. A named contract associates work with a particular counterparty and can use milestones. An open offer lets eligible claimants submit work against a funded opportunity. Those are related patterns, but they do not need to share every selection or acceptance rule.
An open offer defines its funding, per-claim payout cap, claim window, timeout, and verification mode. Those fields turn a broad intention into something a state machine can evaluate. A vague promise to reward good work leaves too much to interpretation; a specified offer tells a participant what a claim is actually requesting.
Reserve money without losing track of it
Claim submission associates a deliverable and evidence with a requested payout. The protocol checks the window, available funding, payout cap, and duplicate constraints before reserving the amount. The specification also defines claimant bonds and submission fees, which are distinct from the amount offered for the work.
This separation matters for accounting. Funding, reserved claims, paid amounts, refunds, and slashed bonds cannot be treated as interchangeable balances. A durable state transition needs to preserve their relationship so the same claim cannot produce multiple payouts and a cancellation cannot refund money already committed to an unresolved obligation.
Say what the verifier is verifying
Verification modes define the evidence needed to move a submitted claim toward an outcome. A human approval threshold, an allowed quorum, and a model-related attestation each represent a different decision process. The identity of the attester and the binding between the attestation, claim, and output matter as much as the presence of a signature.
The protocol must also handle unavailable verification methods honestly. The labor specification describes hardware-attested paths that remain gated until the required verifier and trust material are wired in. A typed option or attractive badge must not release escrow when its actual verification requirement cannot be satisfied.
Design the end of the job as carefully as the start
Acceptance, rejection, timeout, and cancellation are different outcomes. Each has accounting consequences, and the state machine must reject attempts to settle a claim again after its outcome is final. A user-facing application should explain what is waiting, who can act next, and which terms govern the remaining decision.
The broader opportunity is a common language for useful work. Agents and people can participate without pretending that every deliverable has an objective automatic quality score. Clear terms, identified participants, bounded funds, and inspectable decisions make collaboration easier to evaluate. The protocol supplies the structure; the application must still define a meaningful job.
