Starting with RalphWicks and going through Harness, I've now reached Loop Engineering.
Since I wasn't going to write prompts directly anyway, and depending on the work scope, loop engineering sometimes takes longer, so I classified by work scope and created a tool that determines whether the current work is suitable for loop engineering.
And I've also enabled it to run loop engineering.

This is the admin project for hubinflow. Feature enhancements are needed for dashboard, user management, payment management, plan management, and subscription management. Add items commonly needed in general admin web, and especially for the Trial plan in plan management, a function to change the trial end date is essential. And for the UI, refer to https://discuss.pytorch.kr/t/nothing-design-skill-nothing-ui-claude-code/10729 and apply a monochrome UI.

┃ Judgment: GREEN ┃
Gate 0 Passed : Yes
GREEN Signal:
• Adding new features to a large and complex (completed) project (5,833 files, 180+ DbSet) with non-destructive integration validation with existing features as the core
• Monochrome UI replacement is an artifact task that requires iterative visual evaluation to improve completeness
▶ Judgment Rationale
HIFlowAppAdmin is a large completed project with 5,833 files, 930 subdirectories, and 180+ EF Core DbSets (CLAUDE.md confirmed). This task involves simultaneously enhancing ①dashboard, user management, payment management, plan management (trial end date change), and subscription management features and ②overall monochrome UI replacement. The scope spans Razor View, Controller, Service, and DB layers making it difficult to complete with a single prompt in a polished manner. Particularly, non-destructive validation of existing features (authentication, SignalR terminal, background services, etc.) is required with each iteration, and UI consistency cannot be verified without visual iterative evaluation. Since none of the three RED conditions (small-scale project, easy one-time task, work that can be replicated once) apply, judgment is GREEN. However, since the goal spans 5 sections+UI, there is scope creep risk, so single_goal must be fixed with "Trial plan end date change" as the core evaluation criterion for functional integration loop.
▶ Derived Loop Specification (loop.md §2)
Single Goal : Enhance standard admin web functionality for HIFlowAppAdmin's dashboard, user management, payment management, plan management (Trial end date change mandatory), and subscription management, apply monochrome UI, and verify with each iteration that existing authentication, terminal, background services, and other current features are not destroyed.
Scoring : Yes (threshold 90, range 0~100)
Evaluation Criteria:
• Required Feature Implementation Rate: Completion ratio of checklist items for each of 5 sections (dashboard, user, payment, plan, subscription) (weight 50%)
• Non-Destructive Verification: Normal operation of existing Controllers (Account, Admin, Node, etc.) routing, authentication cookies, SignalR terminal, background services (weight 30%)
• Monochrome UI Consistency: Color palette compliance, typography, component style unity across all Razor Views (weight 20%)

⚠ Claude will now create/modify actual files in the work directory in 'bypassPermissions' authority mode.
⚠ bypassPermissions bypasses all approvals (file writes/command execution). Use only in trusted directories.
Start the loop? [y/N]
This is the judgment result that comes out like this,
── iteration 1/20 ──────────────────────────────────────
· Running claude… (model: default, authority: bypassPermissions, attempt 1/2)
And it runs iterations with claude like this.
Without worrying about anything else, I've now made it possible to run loop engineering with just a one-line prompt. Haha.
