# Economic Regression Sentinel

## Why This Skill Exists
We need this skill because missions need explicit tradeoff logic for cost, speed, and impact. This specific skill prevents unnoticed quality drift after updates.

## When To Use
Use this skill when the request explicitly needs "Economic Regression Sentinel" outcomes in the Economic Optimization domain.

## Step-by-Step Implementation Guide
1. Define the scope and success metrics for `Economic Regression Sentinel`, including at least three measurable KPIs tied to overspending and low-impact allocation.
2. Design and version the input/output contract for budgets, costs, benefits, and opportunity values, then add schema validation and failure-mode handling.
3. Implement the core capability using baseline-delta detection, and produce regression watchlists with deterministic scoring.
4. Integrate the skill into swarm orchestration: task routing, approval gates, retry strategy, and rollback controls.
5. Add unit, integration, and simulation tests that explicitly cover overspending and low-impact allocation, then run regression baselines.
6. Deploy behind a feature flag, monitor telemetry/alerts for two release cycles, and iterate thresholds based on observed outcomes.

## Required Deliverables
- Capability contract: input schema, deterministic scoring, output schema, and failure modes.
- Runtime profile: detection-guard using baseline-delta detection to produce regression watchlists.
- Orchestration integration: economic-optimization:detection-guard routing, approval gates, retries, and rollback controls.
- Validation evidence: unit, integration, simulation, regression-baseline suites and rollout telemetry.

## Operational Runbook
### Preflight
- Confirm the Economic Regression Sentinel request scope, source evidence, and measurable success criteria before execution.
- Verify feature flag skill_0337_economic-regression-sentinel, approval gates, and rollback owner before autonomous use.

### Execution
- Execute baseline-delta detection with deterministic scoring and reproducible trace capture.
- Produce regression watchlists plus scorecard, assumptions, and unresolved-risk notes.

### Recovery
- Fail closed when required signals, evidence, or approval gates are missing.
- Rollback to the last stable baseline when posture is critical or validation fails.

### Handoff
- Publish regression watchlists, validation evidence, and telemetry links to downstream owners.
- Queue follow-up tasks for unresolved risks, threshold tuning, or approval review.

## Guardrails
- [quality] Require deterministic scoring and validation evidence before promotion.
- [reliability] Preserve retries, rollback controls, and failure-mode evidence for every run.
- [safety] Route critical posture or missing approval gates to human review before autonomous action.
