types

Single-file type checking that never hangs. All operations complete in <5 seconds.

First: check_file

After EVERY edit, verify types:

check_file({ file: 'src/edited.ts' })

Quick Reference

Design Philosophy

• Single file focus - optimized for checking ONE file at a time
• No state - reads fresh from disk every time, never stale
• 5 second timeout - fails fast, never hangs
• For project-wide checks - use tsc --noEmit via task_runner

Common Workflows

After Every Edit

check_file({ file: 'src/api.ts' })

Understanding Unknown Code

get_type({ file: 'src/api.ts', line: 42, column: 15 })
go_to_definition({ file: 'src/api.ts', line: 42, column: 15 })

Fixing Type Errors

check_file({ file: 'src/broken.ts' })
get_quick_fixes({ file: 'src/broken.ts', line: 10, column: 5 })

Project-Wide Checks

task_run({ command: 'tsc --noEmit' })

Integration

Run check_file after using syntax.edit_symbol to verify your changes.
