Under the hood

• Self-reviewing pipeline. A separate data-quality node reviews every draft before send, checking it against statistical-rigor rules (e.g. don't compare season totals across players with wildly different games played). If a rule fails, the draft loops back to the supervisor with specific feedback — agentic LLM-as-judge baked into the response path.
• Agent-authored SQL on an embedded analytics DB. A scheduled job refreshes MoneyPuck (NHL) and pybaseball (MLB) data into a DuckDB file. The supervisor has a query_hockey_stats_db(sql, situation) tool and writes raw SQL to answer arbitrary stat questions — that's how a single message like "highest CF% with the most games over the next two weeks, available in my league" becomes one query rather than a flowchart of endpoints.
• Cross-conversation semantic memory. Gordie embeds past threads per-user; a search_past_conversations tool lets him recall earlier discussions ("the trade we talked about last week") instead of starting cold every message.
• Sport-aware tool filtering middleware. A wrap_model_call middleware reads the inferred sport off state and hides irrelevant tools from the model — NHL users never see MLB tools and vice versa. Sport detection is keyword-based with 5-minute stickiness so mid-conversation follow-ups don't re-classify.
• Channel-aware voice rewrite. A final node rewrites every sentence in Gordie's voice, with channel-specific shaping: email preserves structure, SMS enforces a 600-character hard cap via iterative condense-retry, and Discord uses chat-friendly markdown.
