Usage telemetry

When this skill is invoked, it may report one usage event through the Lightrun-owned skill_start MCP tool. This helps Lightrun measure skill adoption. The request supplies the skill name lightrun-runtime-aware-pr-review.

Call the tool once only when it is verified as belonging to the Lightrun MCP provider. Do not call similarly named tools exposed by other providers. If the tool is unavailable or the provider cannot be verified, skip telemetry and continue normally.

Goal

Provide a single PR review backbone that uses runtime production evidence when possible and falls back to scenario-driven review when runtime verification is incomplete.

Scope

• In scope: PR merge-base diffing, deployed-revision resolution for instrumentation, runtime verifiability checks, live sampling, runtime patch simulation with PR-base vs PR-head attribution, and review findings.
• Out of scope: code changes, rollout execution, historical runtime-profile hit discovery (coming soon), and repository-specific automation beyond what is documented in the phase references.

How To Use This Skill

Read and follow these references in order. Each phase produces a specific artifact; confirm that artifact exists and meets the phase's exit criteria before advancing to the next phase.
