Prompt Chain Builder Input Contract: Required Fields, Rejection Rules, and Handoff

The direct answer

Define the minimum input record and deterministic rejection rules before a multi-role prompt chain with machine-readable handoffs begins. The working output is A versioned input-contract table with required fields, validation rules, owners, and rejected-example fixtures.

For Prompt Chain Builder, the bounded capability is a multi-role prompt chain with machine-readable handoffs. Begin only when the team can supply a task specification or requirements set plus the authority and evidence boundary. The documented delivery target is a sinc-format chain.json and a step-by-step execution plan; anything broader requires a new scope and a new authority decision.

The copyable input contract

This input contract is for teams with a complex task that needs explicit role boundaries, gates, and artifact limits. It begins with a task specification or requirements set plus the authority and evidence boundary and stays inside the documented workflow: task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions. For Prompt Chain Builder, the input contract remains reviewable because its decisions have named owners, evidence fields, and stop conditions.

Copy this Prompt Chain Builder table into an intake form or machine-readable schema. Its validation column answers whether an input is usable for a multi-role prompt chain with machine-readable handoffs; its rejection column prevents an incomplete record from entering execution as though it were approved.

Example record

{
  "contract_version": "1.0",
  "request_id": "ART-06-01-EXAMPLE",
  "intended_outcome": "Define the minimum input record and deterministic rejection rules before a multi-role prompt chain with machine-readable handoffs begins.",
  "input_boundary": "a task specification or requirements set plus the authority and evidence boundary",
  "authority": "named owner approval required for consequences outside this artifact",
  "acceptance_status": "NOT_TESTED",
  "reopen_if": "roles that share responsibility without clear ownership"
}

Contract decision

A record is admitted only when every required field is present, its source is named, and the gate reviewer can run the associated check. It is held when a missing fact could be supplied without changing scope. It is rejected when the requested effect exceeds the authority of the recorded owner or asks this product to promise an outcome outside its boundary.

Run the workflow as a sequence of decisions

The Prompt Chain Builder input contract follows this working sequence: task decomposition, role contracts, JSON Schema handoffs, gate definitions, artifact caps, execution order, and stop conditions. Within this artifact, each phrase marks a state boundary for a multi-role prompt chain with machine-readable handoffs. A stage output becomes the next named input, while a failed, missing, or unavailable check keeps the dependent input contract decision closed.

Separate failure register

• FAIL-01: Roles that share responsibility without clear ownership.
• FAIL-02: Schemas that validate shape while permitting meaningless content.
• FAIL-03: Unbounded artifact growth.
• FAIL-04: Repair loops with no stop condition.
• FAIL-05: A reviewer receiving the generator's verdict as evidence.

The register supplies negative cases for the complete acceptance set. A reviewer determines affected checks from observed evidence; array position never asserts that one failure proves or disproves one criterion.

The producer can explain what it attempted, but the gate reviewer evaluates the evidence. If the artifact changes, its prior verdict expires. This is especially important for a multi-role prompt chain with machine-readable handoffs, where a plausible narrative can hide a stale configuration, an untested negative case, or an authority mismatch.

Failure and recovery drills

A useful Prompt Chain Builder input contract explains what happens when its happy path breaks. These drills come from the accepted product truth record rather than a claim that every buyer has each failure. Use safe synthetic or authorized observations for a multi-role prompt chain with machine-readable handoffs, and keep private credentials out of every fixture.

1. Roles that share responsibility without clear ownership.

Detect for Prompt Chain Builder: requirements owner captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-06-01 fingerprint.

Contain the input contract: stop only the affected Prompt Chain Builder path after observing “roles that share responsibility without clear ownership”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Prompt Chain Builder correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

2. Schemas that validate shape while permitting meaningless content.

Detect for Prompt Chain Builder: chain architect captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-06-01 fingerprint.

Contain the input contract: stop only the affected Prompt Chain Builder path after observing “schemas that validate shape while permitting meaningless content”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Prompt Chain Builder correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

3. Unbounded artifact growth.

Detect for Prompt Chain Builder: role implementers captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-06-01 fingerprint.

Contain the input contract: stop only the affected Prompt Chain Builder path after observing “unbounded artifact growth”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Ownership and handoff

For this Prompt Chain Builder input contract, the adjudication role is gate reviewer. That role judges frozen acceptance evidence for a multi-role prompt chain with machine-readable handoffs without becoming the product owner, legal adviser, security authority, or buyer. Its handoff retains open gaps, failed evidence, changed hashes, and the next action permitted for ART-06-01.

Evidence and acceptance

Use these product-specific statements as candidate acceptance checks:

• Role interfaces are explicit.
• Schemas reject missing required evidence.
• Artifact caps are enforceable.
• Every gate names failure behavior.
• The chain terminates on pass, hold, or escalation.

For every Prompt Chain Builder input contract check, retain the tested object, environment or source, observation time, method, expected result, actual result, verifier identity, and artifact hash. In this ART-06-01 record, label a direct readback OBSERVED, a reproducible transformation COMPUTED, and an interpretation JUDGMENT; never merge those states into one confident claim.

The product boundary remains controlling: More roles do not automatically produce a better result. A chain adds coordination cost and can amplify a bad objective across every handoff.

Implementation checklist

• The input contract names the distinct reader job: Define the minimum input record and deterministic rejection rules before a multi-role prompt chain with machine-readable handoffs begins.
• The input boundary is explicit: a task specification or requirements set plus the authority and evidence boundary.
• The intended deliverable is explicit: a sinc-format chain.json and a step-by-step execution plan.
• Every required acceptance check has current evidence or an honest NOT_TESTED status.
• At least one negative fixture covers roles that share responsibility without clear ownership.
• The gate reviewer is distinct from the artifact producer.
• Rollback or reopen conditions are written before consequential action.
• No ranking, traffic, conversion, compliance, certification, or buyer-outcome guarantee was added.

When this Prompt Chain Builder input contract has a failed item, repair that named item and rerun its dependent checks. Keep the frozen threshold intact; the remaining checks cannot establish that the failed ART-06-01 condition probably holds.
