What problem does it solve? When a pull request changes a voice agent, the repository's committed Cekura test suite often falls out of sync, and manually deciding which test cases need updating is slow and error-prone. This Skill reads the PR diff against its merge base, decides per change whether existing cases already cover it, and makes the smallest edit that closes a real gap. ## Core Features & Use Cases - Diff-driven triage: Translates each changed hunk into transcript-observable behavior using a per-layer decision table covering prompts, providers, thresholds, tools, languages, and transports. - Minimal edit ladder: Chooses the cheapest edit mode (KEEP, TIGHTEN, EXTEND, REPLACE, RETIRE, ADD) so suites stay stable and case keys preserve their history. - Offline validation: Lints edited specs and runs a dry-run validation against the Cekura API without ever placing a live call. - Use Case: A pull request lowers the idle prompt timer from 10s to 6s. The Skill detects that the existing idle-recovery case's 8s silence now straddles the new timer, replaces the turn value in place, keeps the case key, and reports the decision table in the PR comment. ## Quick Start Ask the assistant to review this pull request and update the committed Cekura test suite for any voice agent changes it contains.
