Security and compliance work is a backlog problem: scanners produce noise, fixes are risky, and auditors want evidence no one has time to assemble. Soundcheck turns that backlog into a performance you can watch, govern, and replay. It's built as a band: eight specialist agents that coordinate entirely through Band: memory, messages, and events, never a shared database or queue. A Bandleader plans the run and recruits the players; Scout ingests the repo into an OrgContext; a Code Scanner, Dependency Auditor, and Secrets Sentinel find issues; a Compliance Mapper ties each finding to SOC 2 and ISO 27001 controls; a Fixer proposes a patch on an isolated branch; and a Reviewer, a different model: checks the diff. The agents are genuinely heterogeneous, split across a frontier lane (AI/ML API) and an open-source lane (Featherless), all in one room, and no paid Anthropic or OpenAI keys. You conduct. Nothing ships without you: the Fixer proposes, the Reviewer cross-checks, and you sign off, an approval captured as a real message in the room, part of the permanent record. Only then does a pull request open, never a merge. Because Band is the system of record, the whole run is provenance-complete and replayable. Every finding chains back through the ledger to its evidence; the Master Tape scrubs the run event-by-event; and a one-click audit deliverable exports the seal, the patch, the review, and the full chain, the artifact an auditor actually receives. The experience is a concert hall. On the Stage, whoever's performing steps into the spotlight; you watch handoffs as threads of light and ask the band questions in-room. When the set ends, the Encore gives a retrospective — a scorecard, each agent's bow, unfinished business you can send back in, and the Mic, where each agent narrates its own part aloud, in order. Multi-tenant by account, defensive-only by design, human-approved by default. Built on Band. MIT-licensed, original work.
