+# Incident: PROMPT-CONTRACT-FAILURES
+
+**Date:** 2026-02-15T01:03:31Z
+**Agent:** onboarding-audit-agent
+**Incident ID:** PROMPT-CONTRACT-FAILURES
+
+## Description
+The `npm test` command fails during onboarding validation due to multiple prompt files violating the strict prompt contract enforced by `scripts/validate-prompt-contract.mjs`.
+
+## Impact
+New developers cannot run `npm test` cleanly after checking out the repository.
+
+## Remediation
+Update all agent prompts in `src/prompts/` to strictly follow the `Scheduler Flow` contract regarding completion commands and log file naming.
