コントラクト

  1. Plugin constructor creates an instance of Plugin with spec and props
  2. Plugin manages custom state via init and apply in spec.state
  3. PluginKey identifies a plugin and retrieves its state and plugin instance from EditorState
  4. Plugin filterTransaction intercepts and allows or prevents transaction execution
  5. Plugin appendTransaction inspects applied transactions and generates follow-up transactions
  6. Plugin view factory initializes view callbacks with update and destroy hooks
  7. EditorState throws RangeError when multiple plugin instances share the same PluginKey
  8. Plugin.getState returns undefined when plugin is not included in the EditorState

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 @tiptap/pm.Plugin in pkg:npm/%40tiptap/pm@3.11.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/pm@3.11.0
Demonstrate these symbols/APIs:
  - @tiptap/pm.Plugin

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.
