Adversarial Review Loop
Has a second, independent model review every change before merge, requiring two reviewers to agree.
Anti-Spin Build Loop
Builds toward a machine-checkable contract and stops itself the moment it detects it is spinning in place.
Build-Test-Fix Loop
Builds the next item on the plan, runs tests, typecheck and lint, and feeds every failure back as the next instruction until the build is green.
Builder-Reviewer Loop
Passes code between a builder and an independent reviewer until the review has no blocking findings and tests pass.
Completion Contract Loop
Defines what "done" means and what evidence proves each requirement before starting, then refuses to claim success without that proof.
Devil's Advocate Loop
Adversarially challenges a design or decision until every serious objection is resolved or explicitly accepted.
Docs Sweep Loop
Keeps documentation aligned with the current codebase and opens a reviewable pull request on every pass.
Five-Minute Maintainer Loop
Every few minutes while you work, makes one small verified repository improvement: one change, one commit.
Goal Refiner Loop
Turns a vague request into a precise goal (end state, how to verify, what not to touch, and the stop condition), then executes.
Human Approval Loop
Runs the task, then pauses and sends approve, revise, or skip before anything ships, with your approval as the stop condition.
Nightly Changelog Loop
Updates the changelog every night with user-relevant changes and notifies the team when it ships.
Overnight PR Routine
A nightly routine that works your open PRs: auto-fixes broken builds, answers review comments in an isolated worktree, and rebases stale branches while you sleep.
Performance Budget Loop
Profiles and optimizes pass after pass until the app stably meets a defined performance budget.
Production Error Sweep Loop
Triages production errors, finds the root cause, ships a tested fix, and repeats until the high-severity queue is clean.
Quality Streak Loop
Runs realistic scenarios and fixes failures until the suite passes N times in a row, with no regressions.
Repository Cleanup Loop
Recovers valuable unmerged work and prunes stale branches and PRs until the repository is tidy.
Test Coverage Loop
Adds meaningful tests pass after pass until the suite reaches a target coverage and stays green.
Ticket-to-PR Loop
Converts open bugs and issues into verified, review-ready pull requests, one ticket per pass.
