Custom Web Automation Agent Input Contract: Required Fields, Rejection Rules, and Handoff
Define the minimum input record and deterministic rejection rules before browser automation for a bounded repetitive workflow begins.
The direct answer
Define the minimum input record and deterministic rejection rules before browser automation for a bounded repetitive workflow begins. The working output is A versioned input-contract table with required fields, validation rules, owners, and rejected-example fixtures.
For Custom Web Automation Agent, the bounded capability is browser automation for a bounded repetitive workflow. Begin only when the team can supply the target workflow, authorized accounts, normal cases, failure cases, and a consequence ceiling. The documented delivery target is an agent that operates the named web application for the bounded workflow; anything broader requires a new scope and a new authority decision.
The copyable input contract
This input contract is for operators whose workflow lives in a real web application and cannot be covered reliably by a simple API integration. It begins with the target workflow, authorized accounts, normal cases, failure cases, and a consequence ceiling and stays inside the documented workflow: state detection, browser actions, assertions, credential boundaries, retries, evidence capture, and human escalation. For Custom Web Automation Agent, the input contract remains reviewable because its decisions have named owners, evidence fields, and stop conditions.
Copy this Custom Web Automation Agent table into an intake form or machine-readable schema. Its validation column answers whether an input is usable for browser automation for a bounded repetitive workflow; its rejection column prevents an incomplete record from entering execution as though it were approved.
| Field | Purpose | Validation rule | Owner | Rejection behavior |
|---|---|---|---|---|
request_id | A stable identifier for this bounded request | Non-empty and unique within the run | workflow owner | Reject duplicate or missing IDs |
intended_outcome | Define the minimum input record and deterministic rejection rules before browser automation for a bounded repetitive workflow begins. | Names one observable decision or artifact | workflow owner | Reject broad or outcome-guaranteeing language |
input_boundary | the target workflow, authorized accounts, normal cases, failure cases, and a consequence ceiling | Source, owner, freshness, and permitted use are recorded | workflow owner | Hold when access or provenance is absent |
workflow_scope | state detection, browser actions, assertions, credential boundaries, retries, evidence capture, and human escalation | Every included stage is named; exclusions stay visible | security reviewer | Reject silent scope expansion |
acceptance_evidence | normal and alternate states are recognized, every state-changing step has a postcondition, secrets are absent from artifacts, retries are bounded and idempotent, and unknown states stop for review | Each criterion maps to an observable check | security reviewer | Return NOT_TESTED when the check cannot run |
failure_fixtures | selectors that identify appearance instead of stable semantics, retries after a state-changing action without idempotency, credentials exposed in logs or screenshots, success declared before the application confirms state, and automation continuing after the page diverges from the known workflow | At least one safe negative case exists | security reviewer | Reject a success-only test set |
handoff | Owner: security reviewer; deliverable: an agent that operates the named web application for the bounded workflow | Recipient, format, expiry, and reopen trigger are explicit | security reviewer | Do not release an ownerless artifact |
Example record
{
"contract_version": "1.0",
"request_id": "ART-04-01-EXAMPLE",
"intended_outcome": "Define the minimum input record and deterministic rejection rules before browser automation for a bounded repetitive workflow begins.",
"input_boundary": "the target workflow, authorized accounts, normal cases, failure cases, and a consequence ceiling",
"authority": "named owner approval required for consequences outside this artifact",
"acceptance_status": "NOT_TESTED",
"reopen_if": "selectors that identify appearance instead of stable semantics"
}Contract decision
A record is admitted only when every required field is present, its source is named, and the security 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 Custom Web Automation Agent input contract follows this working sequence: state detection, browser actions, assertions, credential boundaries, retries, evidence capture, and human escalation. Within this artifact, each phrase marks a state boundary for browser automation for a bounded repetitive workflow. A stage output becomes the next named input, while a failed, missing, or unavailable check keeps the dependent input contract decision closed.
| Step | Decision owner | Observable criterion | Evidence to retain | Counterexample policy |
|---|---|---|---|---|
| 1 | workflow owner | Normal and alternate states are recognized. | Direct observation or test bound to the current artifact | Run a safe negative fixture from the separate failure register; do not infer a one-to-one mapping by list position. |
| 2 | account owner | Every state-changing step has a postcondition. | Direct observation or test bound to the current artifact | Run a safe negative fixture from the separate failure register; do not infer a one-to-one mapping by list position. |
| 3 | automation engineer | Secrets are absent from artifacts. | Direct observation or test bound to the current artifact | Run a safe negative fixture from the separate failure register; do not infer a one-to-one mapping by list position. |
| 4 | security reviewer | Retries are bounded and idempotent. | Direct observation or test bound to the current artifact | Run a safe negative fixture from the separate failure register; do not infer a one-to-one mapping by list position. |
| 5 | on-call operator | Unknown states stop for review. | Direct observation or test bound to the current artifact | Run a safe negative fixture from the separate failure register; do not infer a one-to-one mapping by list position. |
Separate failure register
FAIL-01: Selectors that identify appearance instead of stable semantics.FAIL-02: Retries after a state-changing action without idempotency.FAIL-03: Credentials exposed in logs or screenshots.FAIL-04: Success declared before the application confirms state.FAIL-05: Automation continuing after the page diverges from the known workflow.
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 security reviewer evaluates the evidence. If the artifact changes, its prior verdict expires. This is especially important for browser automation for a bounded repetitive workflow, where a plausible narrative can hide a stale configuration, an untested negative case, or an authority mismatch.
Failure and recovery drills
A useful Custom Web Automation Agent 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 browser automation for a bounded repetitive workflow, and keep private credentials out of every fixture.
1. Selectors that identify appearance instead of stable semantics.
Detect for Custom Web Automation Agent: workflow 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-04-01 fingerprint.
Contain the input contract: stop only the affected Custom Web Automation Agent path after observing “selectors that identify appearance instead of stable semantics”. 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 Custom Web Automation Agent 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. Retries after a state-changing action without idempotency.
Detect for Custom Web Automation Agent: account 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-04-01 fingerprint.

Ownership and handoff
| Role | Owned decision | Separation rule |
|---|---|---|
| workflow owner | owns the request boundary and confirms the intended consequence | May not approve evidence it produced when independent review is required |
| account owner | owns the bounded implementation surface and action receipt | May not approve evidence it produced when independent review is required |
| automation engineer | owns source material, freshness, and the claim-to-evidence map | May not approve evidence it produced when independent review is required |
| security reviewer | owns release readiness, rollback, and destination verification | May not approve evidence it produced when independent review is required |
| on-call operator | owns the human approval or escalation decision | May not approve evidence it produced when independent review is required |
For this Custom Web Automation Agent input contract, the adjudication role is security reviewer. That role judges frozen acceptance evidence for browser automation for a bounded repetitive workflow 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-04-01.
Evidence and acceptance
Use these product-specific statements as candidate acceptance checks:
- Normal and alternate states are recognized.
- Every state-changing step has a postcondition.
- Secrets are absent from artifacts.
- Retries are bounded and idempotent.
- Unknown states stop for review.
For every Custom Web Automation Agent 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-04-01 record, label a direct readback OBSERVED, a reproducible transformation COMPUTED, and an interpretation JUDGMENT; never merge those states into one confident claim.
The admitted Search Console packet contained no article-specific demand observation for this exact topic. The page is therefore justified by its distinct operator job and product truth, not by an invented volume estimate. Performance remains unknown until measured after an authorized release.
The product boundary remains controlling: Browser control does not grant authority to bypass access controls, terms, rate limits, or human approval for consequential actions.
Implementation checklist
- The input contract names the distinct reader job: Define the minimum input record and deterministic rejection rules before browser automation for a bounded repetitive workflow begins.
- The input boundary is explicit: the target workflow, authorized accounts, normal cases, failure cases, and a consequence ceiling.
- The intended deliverable is explicit: an agent that operates the named web application for the bounded workflow.
- Every required acceptance check has current evidence or an honest NOT_TESTED status.
- At least one negative fixture covers selectors that identify appearance instead of stable semantics.
- The security 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 Custom Web Automation Agent 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-04-01 condition probably holds.
