U0619 Security Knowledge Graph Linker

Security Knowledge Graph Linker

Why This Skill Exists

We need this skill because production autonomy must default to least privilege and strong privacy. This specific skill connects fragmented facts into reusable structures.

When To Use

Use this skill when the request explicitly needs "Security Knowledge Graph Linker" outcomes in the Security and Privacy domain.

Step-by-Step Implementation Guide

1. Define the scope and success metrics for Security Knowledge Graph Linker, including at least three measurable KPIs tied to breach, exfiltration, and over-privileged actions.
2. Design and version the input/output contract for permissions, sensitive data flows, and threat events, then add schema validation and failure-mode handling.
3. Implement the core capability using entity and relation linking, and produce linked knowledge entities 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 breach, exfiltration, and over-privileged actions, 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: general-capability using entity and relation linking to produce linked knowledge entities.
• Orchestration integration: security-and-privacy:general-capability routing, approval gates, retries, and rollback controls.
• Validation evidence: unit, integration, simulation, regression-baseline suites and rollout telemetry.

Operational Runbook

Preflight

• Confirm the Security Knowledge Graph Linker request scope, source evidence, and measurable success criteria before execution.
• Verify feature flag skill_0619_security-knowledge-graph-linker, approval gates, and rollback owner before autonomous use.

Execution

• Execute entity and relation linking with deterministic scoring and reproducible trace capture.
• Produce linked knowledge entities 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 linked knowledge entities, 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.
