srcnav - Semantic Code Navigation for AI Agents

srcnav

Code Navigation for AI Agents

Give your AI the context it needs

srcnav provides semantic code search.
400x better signal-to-noise. 93x faster.
Built for AI agents, by AI developers.

WITHOUT

grep

Traditional string matching

20k+ matches for "create"
~4s query time
15k avg tokens/query
strings what it finds

$ grep -r "create" .

20,077 matches

// includes comments

// includes strings

Limitations

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

srcnav

Semantic code navigation

50 definitions for "create"
~43ms query time
500 avg tokens/query
semantic what it finds

$ srcnav find "create"

50 definitions

JSON output

Impact analysis

Capabilities

  • Finds actual definitions
  • Full dependency graph
  • Instant impact analysis
  • JSON output for AI agents

What srcnav Gives Your AI

grep

$ grep -r "create" .
20,077 matches in files
// Strings, comments, everything

AI must process thousands of lines

Manual filtering required

srcnav

$ srcnav find "create"
{
  "definitions": 50,
  "format": "json",
  "time": "43ms"
}

Clean, structured results

Ready for AI consumption

Why This Matters

Signal-to-Noise Ratio (Benchmark: TypeScript codebase)

grep "create"
20,077 matches
srcnav find "create"
50 definitions
grep: all string matches srcnav: actual definitions

400x fewer results to process = less context for AI to read

400x Better signal-to-noise
93x Faster queries (43ms vs 4s)
213K Items affected by a change

Real Test Results
