Iteration Timeline
First run of Riley against the full persona suite.
Diagnosis: Discloses to third parties, skips the mini-Miranda when the caller is eager, re-pitches after a cease, and rambles on voicemail.
Claude rewrote the verification + disclosure rules.
Diagnosis: Agent leaked the creditor to a third party and coaxed verification by hinting at the balance.
Claude’s fix: Added a hard gate: no creditor name, balance, or debt implication until verify_identity succeeds; never hint at the correct identifier.
Claude tightened the harassment and stop-collecting rules.
Diagnosis: Matched an angry caller's tone, mentioned credit impact, and re-pitched a plan right after a cease request.
Claude’s fix: Lowered energy on hostility, banned credit/legal threats, and made cease + dispute immediate hard-stops with no re-pitch.
Final hardening pass — full compliance reached.
Diagnosis: Skipped the mini-Miranda for eager payers and rambled into dead air on voicemail.
Claude’s fix: Made the verbatim mini-Miranda mandatory before any balance; added turn-taking discipline and a compliant voicemail path.
