DEPENDENCY MAPPING

Dependency Mapping: Every Connection Traced

Before you change that function, wouldn't you like to know everywhere it's called? LOOM shows exactly what's connected—and what breaks if you touch it.

The Most Expensive Bug: Unexpected Dependencies

You make a small change. Tests pass locally. You deploy. Then bug reports roll in from a completely different part of the application.

"I had no idea that utility was used by payment." "Nobody told me that class had 12 children." "The import chain went through 6 files."

LOOM eliminates these surprises. Before you touch anything, you know everything it touches.

Every Type of Dependency, Fully Traced

Function Calls

Who calls this function? What does it call? The complete call graph across every file boundary.

[SCREENSHOT: Call tree showing A→B→C→D with bidirectional navigation and call counts at each level.]

Import Chains

Follow imports from entry to leaf. See how modules connect. Identify circular dependencies before they cause problems.

[SCREENSHOT: Import chain with circular dependency highlighted in red, showing exactly where the cycle forms.]

Class Hierarchies

Extends. Implements. Mixins. See the full inheritance tree and understand how changes propagate down.

[SCREENSHOT: Multi-level class hierarchy tree with method overrides indicated.]

Data Flow

Where does this variable come from? Where does it go? Trace data through your entire application—from user input to database and back.

[SCREENSHOT: Data flow trace from HTTP request body → controller → service → database query → response. Each transformation step labeled.]

Impact Analysis: Know Before You Code

Select any element. LOOM instantly shows everything that depends on it—directly and transitively.

12 Direct Dependents

Code that directly calls/imports this element

147 Transitive Dependents

Everything affected through the chain

8 Files Affected

The scope of your blast radius

Change this function? 147 things might break. Good to know before you commit.

Rich Relationship Metadata

LOOM doesn't just show that A connects to B. It shows you how and with what confidence.

Edge: CheckoutController → PaymentService
─────────────────────────────────────────
type:       function_call
from:       submit() @ line 45
to:         processPayment()
confidence: 100% (static)
context:    inside try/catch
resolved:   ✓ target found

This metadata enables queries like "calls to processPayment not inside try/catch"—see Registry querying

Dependency Mapping in Action

Safe Refactoring

Renaming a function? Moving a file? See every place you need to update—no "search and hope."

Legacy modernization

Code Review

Reviewing a PR? See the true scope of changes, not just the diff. Understand impact before approval.

Circular Dependencies: Found and Flagged

Circular dependencies cause slow builds, testing nightmares, and architectural debt. LOOM detects and visualizes them automatically.

Stop Guessing What Depends on What

Every change has consequences. LOOM shows you exactly what they are—before you make them.
