Audit. Fix.
Live on stage.

Soundcheck is a governed, replayable autonomous workforce for security & compliance. A band of specialist agents audits your repo, maps findings to controls, proposes fixes, and reviews them across models - and you approve every change.

how the set runs

Six moves, one Band room.

The same trail the agents perform is the trail you replay later. Nothing happens off the record.

  1. 01
    Audit
    Scanners read the repo - static analysis, dependency CVEs, committed secrets.
  2. 02
    Map
    Every finding is mapped to SOC 2 / ISO 27001 controls - evidence, not noise.
  3. 03
    Fix
    The Fixer proposes a safe patch on an isolated branch. Main is never touched.
  4. 04
    Review
    A different model reviews the diff - cross-model, never self-grading.
  5. 05
    Approve
    You authorize the change. No autonomous merges, ever.
  6. 06
    Ship
    A pull request opens against the repo - opened for you, never merged.
the lineup

Eight specialists. Two providers. One room.

Genuinely heterogeneous agents - frontier and open-source models, across frameworks - coordinating only through Band.

governance, by design

Human authority before anything ships.

No autonomous merges. The Fixer proposes; a second model reviews; you sign off. Approval is a real message in the room, captured forever as part of the record.

  • You hold the baton. Every patch waits for your sign-off - captured as an Approval.
  • Fully replayable. Scrub the whole run on the Master Tape - every event, in order.
  • Provenance to the source. Each finding chains back through the Band ledger - the auditor’s deliverable.
