Contract Redline War Room

Contract Redline War Room is a regulated, multi-agent contract review desk where five specialized AI agents - Coordinator, Legal, Risk, Finance, and Compliance - collaborate through Band to redline a contract, quantify financial exposure, and assemble an approval packet that no single agent can sign off on alone. The Coordinator opens a Band room, discovers its peers with band_lookup_peers, and recruits the specialists with band_add_participant. Legal redlines clauses and cites the exact source text. Risk scores severity and dollar exposure. Finance computes worst-case financial impact. Compliance runs a policy check using Featherless AI's open-source inference and can VETO the recommendation, forcing a visible Coordinator re-plan loop - this is real coordination, not a fixed pipeline. Every agent-to-agent handoff, finding, state change, and discovery is a genuine Band primitive (band_send_message with @mentions, band_send_event, band_lookup_peers, band_add_participant, band_create_chatroom) driven through the real Band SDK, with each agent authenticating with its own API key. Once the agents converge on an aggregated exposure score and redline packet, a human reviewer holds the only key: Approve, Reject, or Request Changes. The decision seals a SHA-256 hash-chained audit trail; GET /api/verify/{id} recomputes the entire chain so any later edit is detectable, giving regulators a defensible record of exactly how the recommendation was reached. AI/ML API powers the primary reasoning for Coordinator, Legal, Risk, and Finance, while Featherless AI serves the Compliance agent's open-source policy-classification model - both partner technologies are exercised live and tallied at /api/health. This turns days of cross-functional contract review into minutes, with a tamper-evident sign-off record built for Track 3: Regulated and High-Stakes Workflows.
