Changelog

March 2026

AI-Tell Suppression Refactor — Writer agent now runs regex-based AI-tell removal on its own output before passing to the editor. Banned words list elevated to position 2 in the system prompt for higher enforcement priority. Editor threshold set to 5 (from 1). Banned words list added to editor and formatter LLM prompts to prevent reintroduction during editing and formatting passes.
Writer Agent Refactored — Removed 3 duplicate method definitions, 4 blocks of unreachable dead code in _resolve_word_limits, fixed structure variable scoping bug. File reduced from 1891 to 1652 lines with zero logic loss.
Generation Failure DB Persistence — run_generation_workflow error handler now writes status: "failed" to the database, preventing infinite status polling on Cloud Run multi-instance deployments.
Call Writer Async Fix — EnhancedCallWriterAgent.execute changed from async to sync to match BaseAgent contract and prevent TypeError: object EnrichedContentState can't be used in 'await' expression.
