speckit-ripple-scan

What problem does it solve?

Ripple scan identifies what an implementation change broke or risked beyond what tests explicitly verify, so you can prevent production regressions caused by side effects spreading through data flows, contracts, and runtime assumptions.

Core Features & Use Cases

• Delta-anchored ripple analysis: Compares the pre-implementation baseline (merge-base with main) against the current HEAD change set to find only newly introduced or worsened issues.
• Blast-radius dependent tracing: Maps each changed file to dependent files to locate where implicit contracts are now at risk.
• Multi-category impact coverage: Evaluates risks across data flow, lifecycle/state, interface contracts, performance, concurrency, distributed coordination, configuration, error propagation, and observability, then assigns severities (critical/warning/info).

Quick Start

Run the command to scan implementation ripples by severity: specify the argument as critical when you only want critical findings.
