Check that a sub-agent delegation states objective, acceptance criteria, budget, evidence and stop conditions

$0.005 USDC per call · Agent infrastructure · POST /api/v1/delegation-contract-check · Id delegation-contract-check

Checks the brief an agent is about to hand to another agent: the required parts are present and non-empty (objective, acceptance criteria, a budget with at least one positive numeric bound, required evidence, stop conditions; output format if required), nothing is duplicated, and acceptance criteria are not made only of vague wording (a small labelled word list: good, appropriate, if possible ...). fail = a required part is missing or a budget bound is not positive; unknown = only vague-wording hints or repeated entries; pass = all present and distinct. Does not judge whether the task is sensible or the criteria sufficient.

What you get

Delegations without a budget, evidence or stop condition are the ones that run away or come back unverifiable.

Example request body

{
  "objective": "List every endpoint in src/routes that lacks auth middleware.",
  "acceptanceCriteria": [
    "Output is a JSON array of {file,line,route}",
    "Every file under src/routes was read"
  ],
  "budget": {
    "maxToolCalls": 40,
    "maxSeconds": 300
  },

  ],
  "stopConditions": [
    "all files read",
    "budget spent: report partial results"
  ]
}

Result

The response is { "data": ..., "_provenance": ... }. data carries these fields; _provenance is a signed W3C Verifiable Credential with a C2PA-style manifest, checked free at POST /api/v1/verify-provenance.

Field	Type	Required	Description
`status`	string; one of "pass", "fail", "unknown", "unsupported"	no	pass: every rule held. fail: a rule was violated (see witnesses). unknown: the input lacks the evidence to decide. unsupported: outside what this engine covers. Missing evidence is never a pass.
`missing`	array<string>	no
`vagueCriteria`	array<integer>	no	Indexes of acceptance criteria containing vague wording (heuristic word list).
`budgetBounds`	array<string>	no	Budget fields that are set to a positive value.
`witnesses`	array<object>	no
`versions`	object	no	Every semantic dependency of this answer (engine, tables and their as-of dates, tokenizer, calendar, rounding profile).
`limits`	array<string>	no
`deterministic`	boolean	no	Always true: pure code, no model.
