U0540 Engineering Semantic Retrieval Ranker

Engineering Semantic Retrieval Ranker

Why This Skill Exists

We need this skill because delivery speed must increase without sacrificing correctness. This specific skill improves recall precision for downstream decision quality.

When To Use

Use this skill when the request explicitly needs "Engineering Semantic Retrieval Ranker" outcomes in the Software Engineering Automation domain.

Step-by-Step Implementation Guide

1. Define the scope and success metrics for Engineering Semantic Retrieval Ranker, including at least three measurable KPIs tied to regressions and brittle release pipelines.
2. Design and version the input/output contract for code changes, tests, incidents, and rollout data, then add schema validation and failure-mode handling.
3. Implement the core capability using semantic relevance scoring, and produce ranked retrieval results 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 regressions and brittle release pipelines, 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: planning-router using semantic relevance scoring to produce ranked retrieval results.
• Orchestration integration: software-engineering-automation:planning-router routing, approval gates, retries, and rollback controls.
• Validation evidence: unit, integration, simulation, regression-baseline suites and rollout telemetry.

Operational Runbook

Preflight

• Confirm the Engineering Semantic Retrieval Ranker request scope, source evidence, and measurable success criteria before execution.
• Verify feature flag skill_0540_engineering-semantic-retrieval-r, approval gates, and rollback owner before autonomous use.

Execution

• Execute semantic relevance scoring with deterministic scoring and reproducible trace capture.
• Produce ranked retrieval results 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 ranked retrieval results, 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.
