  4. Discovery helpers (lines 482-620)
     4a. discoverExtensions() — scans directories for extensions (lines 482-540)
     4b. globForType() — finds files matching extension type patterns (lines 542-590)
     4c. resolveExtensionPath() — resolves relative paths to absolute (lines 592-620)
 
  5. Deployment logic (lines 622-847)
     5a. deployToProvider() — deploys extension to a platform provider (lines 622-720)
     5b. buildProviderConfig() — generates provider-specific config (lines 722-790)
     5c. writeDeploymentFiles() — writes files to provider directories (lines 792-847)
 
Quick Commands:
  Read lines 87-145    → register() method
  Read lines 322-390   → validateExtension()
  Read lines 622-720   → deployToProvider()
  Grep "register"      → 14 matches across sections 2, 3
  Grep "deploy"        → 8 matches in section 5

  2b. register() — registers an extension (lines 87-145)

  2. ExtensionRegistry class (lines 47-320) — 5 methods, 274 lines

  2b-i.   register() parameter validation (lines 87-95)
  2b-ii.  register() type checking (lines 96-120)
  2b-iii. register() storage and indexing (lines 121-145)

User: "map src/extensions/registry.ts"
 
Skill produces the navigable map showing 5 sections with line ranges.
Agent can then read only the section needed:
  "Read lines 87-145 of src/extensions/registry.ts"

User: "/code-chunker src/extensions/registry.ts --section 3"
 
Skill:
1. Generates map (or uses cached version)
2. Immediately reads and displays section 3 (Validation functions, lines 322-480)
 
Output: Full content of lines 322-480 with the map as header context.

User: "/code-chunker src/large-file.py --format json"
 
Skill produces JSON map that another agent or script can consume
to programmatically navigate the file.

Agent reads src/legacy/monolith.ts (920 lines)
→ Auto-chunk: "File is 920 lines. Here's the structure map.
   Which section do you need?"
