zwright8 Observability Regression Sentinel
Why This Skill Exists
We need this skill because decisions are only as good as the quality and visibility of data. This specific skill prevents unnoticed quality drift after updates.
When To Use
Use this skill when the request explicitly needs "Observability Regression Sentinel" outcomes in the Data Quality and Observability domain.
Step-by-Step Implementation Guide
- Define the scope and success metrics for
Observability Regression Sentinel, including at least three measurable KPIs tied to data drift and blind spots. - Design and version the input/output contract for freshness, drift, schema health, and telemetry coverage, then add schema validation and failure-mode handling.
- Implement the core capability using baseline-delta detection, and produce regression watchlists with deterministic scoring.
- Integrate the skill into swarm orchestration: task routing, approval gates, retry strategy, and rollback controls.
- Add unit, integration, and simulation tests that explicitly cover data drift and blind spots, then run regression baselines.
- 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: data-quality-and-observability: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 Observability Regression Sentinel request scope, source evidence, and measurable success criteria before execution.
- Verify feature flag skill_0577_observability-regression-sentine, 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.
