Three-Musketeers

Orchestrate a long or complex BUILD through three separate subagents — a Builder that does the work, an Adversarial Reviewer whose only job is to poke holes in it, and a Verifier that confirms it genuinely works by behaving as a user (browser/computer use) — looping until the adversary finds nothing and the verifier passes. The build moves in CHECKPOINTS: small shippable slices, each published and reported with a short status update as soon as it is verified, with narrow reviewers fanned out in parallel. Use when the user wants to build something substantial and have a separate agent try to break or critique it and then verify it actually works — e.g. 'build it, have another agent poke holes, then verify it works', 'build, review, and verify this with subagents', 'drive this build with a builder, reviewer, and verifier', 'loop until it's genuinely done'. This is the build/verify phase — NOT planning a sketch (use adom-plan) and NOT auditing a finished artifact (use deep-audit). Triggers: /three-musketeers, three musketeers, builder adversary verifier, adversarial build loop, checkpoint and publish, build in checkpoints, parallel reviewers, status updates during a build, build and verify with subagents, run the musketeers, all for one.
