description: Operate the "Oversight Uncertainty Communicator" capability in production for Human Oversight and Operator UX workflows. Use when mission execution explicitly requires this capability and outcomes must be reproducible, policy-gated, and handoff-ready.

# 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.
