コントラクト

  1. plugin exports a default plugin factory asserting Babel 7 or 8 compatibility
  2. plugin factory returns plugin descriptor named syntax-typescript with manipulateOptions method
  3. manipulateOptions removes flow and jsx plugins and adds objectRestSpread and classProperties
  4. manipulateOptions enables typescript parser plugin with disallowAmbiguousJSXLike and dts options
  5. manipulateOptions re-enables jsx parser plugin when isTSX option is true
  6. configureParserOptions helper initializes plugin and configures parser options in single step
  7. getTypeScriptPluginConfig helper extracts typescript options from configured parser plugins

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:npm/%40babel/plugin-syntax-typescript@7.29.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/plugin-syntax-typescript@7.29.7
Demonstrate these symbols/APIs:
  - @babel/plugin-syntax-typescript

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
