SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps debug and fix bugs in complex, side-effect-heavy scripts by reducing context and isolating the core logic.

Core Features & Use Cases

Isolate side effects: Create a controlled environment to replicate bugs
Extract core logic: Reimplement core logic for deterministic reasoning
Minimize integration risk: Reintegrate fixes with minimal changes

Quick Start

Identify the core logic, create a sandbox, reproduce the bug there, then apply a fix.

FAQPage Schema

How do I debug shell scripts that have side effects like file I/O or external commands?▼

Isolate side effects by extracting core logic into a separate, testable function. Create a controlled sandbox environment with mocked or fixed inputs to reproduce the bug deterministically, then validate the fix before reintegrating it into the original script.

What's the best way to fix bugs in scripts when unit tests don't exist?▼

Reproduce the bug in isolation by extracting the core logic from side-effect-heavy code. Use a controlled environment with fixed inputs or mocks to validate the root cause, then apply and verify the fix with minimal changes to the original orchestration.

How do I reduce complexity when debugging scripts that depend on timing or environment mutations?▼

Debugging side-effect-heavy scripts means reducing state space by isolating environmental dependencies. Extract deterministic core logic, test it independently with controlled inputs, then safely reintegrate fixes to minimize integration risk.

Can I test shell script logic without running the full script with all its side effects?▼

Yes. Extract the core logic into a separate module, mock external command calls and I/O operations, then test the logic deterministically. This lets you validate fixes in isolation before reintegrating them into the orchestration layer.

When should I extract core logic from a shell script instead of patching it directly?▼

Extract core logic when scripts perform I/O, call external commands, mutate environment, or depend on timing—especially when bugs are hard to reproduce. Isolation creates a controlled environment for deterministic validation and reduces risk during reintegration.
