U0225 Oversight Uncertainty Communicator

Oversight Uncertainty Communicator

Why This Skill Exists

This skill hardens a generated capability for production execution so oversight workflows remain deterministic, auditable, and fail-closed under risk.

When To Use

Use this skill only when the request explicitly needs Oversight Uncertainty Communicator in Human Oversight and Operator UX and a downstream consumer requires contract-bound artifacts.

Step-by-Step Implementation Guide

1. Validate production trigger criteria: explicit capability request, approved source-tagged inputs, and named downstream consumer.
2. Enforce deterministic normalization workflow with pinned mapping/ruleset versions and stable serialization order.
3. Apply explicit determinism tolerance checks (score delta <= 0.005 absolute; identical input must produce zero artifact hash drift).
4. Execute fail-closed validation gates (schema, determinism, policy-risk) and block output on any failure.
5. Require explicit human sign-off token for high-risk runs before publication or downstream routing.
6. Emit handoff envelope with artifact paths, gate results, risk tier, and approval state for the next stage.

Deterministic Workflow Constraints

• Replay score variance: <= 0.005 absolute per item.
• Artifact hash drift for identical replay: 0 allowed.
• Time-dependent fields allowed only in metadata and excluded from scoring.

Validation Gates

1. schema-gate — all required fields present and schema-valid; otherwise block and return error bundle.
2. determinism-gate — replay output within tolerance; otherwise quarantine and escalate.
3. policy-risk-gate — policy and risk checks pass; otherwise block routing.
4. approval-gate-high-risk — if risk is high, require human sign-off token; otherwise fail closed.

Handoff Contract

• Inputs: source-tagged signals, claims, evidence, confidence traces, run context.
• Outputs: deterministic artifact, scorecard, and handoff envelope with approval metadata.
• Routing rule: forward only when every gate passes; high-risk requires explicit sign-off token.

Immediate Hardening Additions

• Fixture: fixtures/minimal-valid.json
• Regression case: tests/regression-case.md
• Machine-readable summary: hardening-summary.json

Production Trigger Clarity

• Use only when this capability produces production-facing outcomes with measurable acceptance criteria.
• Do not invoke for exploratory brainstorming or unrelated domains; route those requests to the correct capability family.

Deterministic Tolerances

• Repeated runs on identical inputs must remain within <=1% output variance for scoring fields and preserve schema-identical artifact shape.
• Any variance beyond tolerance is a hard failure and must trigger escalation.

Fail-Closed Validation Gates

1. Schema validity gate (required inputs present and valid).
2. Determinism gate (variance within tolerance).
3. Policy/approval gate (required approvals satisfied).

If any gate fails: block output publication and fail closed.

High-Risk Human Sign-Off

• Any high-risk change, policy-impacting output, or publish-level action requires explicit human sign-off before release.
• Missing sign-off is a blocking condition.

Explicit Handoff Contract

• Produces: normalized artifacts, decision scorecard, risk/confidence metadata.
• Consumes: validated upstream inputs for this capability.
• Next hop: route only to declared downstream consumers with gate/approval context attached.
