~700msquery time

2.7kmatches for "useState"

stringswhat it finds

$ ▋

$ grep -rn "createElement" .
5,713 matches
// strings, comments, usage, everything

$ ▋

$ grep -rn "function createElement" .

Limitations

Matches everything with the string
No concept of definitions vs usage
No dependency tracking
No impact analysis

Code Navigation That Scales

AI agents need precise code navigation, not text search.

Why Impact Analysis Matters

When an AI agent modifies code, it needs to understand the consequences.

⚠️

Without Impact Analysis

AI blindly makes changes and hopes nothing breaks. Tests fail. Bugs appear in production.

✓

With Impact Analysis

AI sees every caller, test file, and dependency before changing code. Makes informed decisions.

Example: Changing a function signature? srcnav shows 47 callers, 23 test files, and 12 indirect dependencies — before a single line is modified.

What AI Agents Can Now Do

Safe Refactoring

Before changing any function, AI knows exactly what will break. Impact analysis shows every caller, test, and dependency.

Find Real Bugs

Trace how data flows through your code. Find missing validation or security issues.

Map Architecture

See the full dependency tree. Find circular dependencies or unused files.

True Understanding

Instantly find any function definition and see all places it's used.

Less Context Needed

AI only loads relevant code. 95% less context. Much cheaper AI calls.

Works at Scale

50,000 files? No problem. Fast queries on any codebase size.
