CLI Extensions Info

`ed extensions info`

Describes one extension without changing anything.

ed extensions info <id> [--json]

Argument	Type / values	Default	What it does
`id`	one of the fifteen ids, or a defaults key	required	The extension to describe

Option	Type / values	Default	What it does
`--json`	flag	off	Emit JSON on stdout instead of the indented block

The human form is the title, the summary, then a fixed set of labelled rows. The needs row appears only when the extension has required permissions and the asks for row only when it has optional ones, so a plain extension prints four rows:

$ ed extensions info clipboard
Clipboard
  Clipboard history with instant paste.
  id       clipboard
  key      clipboardEnabled
  group    Utilities
  state    on
  asks for Accessibility

$ ed extensions info calendar
Calendar
  Shows your schedule in the panel and the app.
  id       calendar
  key      tabCalendarEnabled
  group    Media
  state    off
  needs    Calendar

needs and asks for print the readable permission names (Input Monitoring, Screen Recording), while --json prints the ids ed permissions request accepts (inputMonitoring, screenRecording).

info is a pure read: no key is written and no notification is posted. The human form does not print capabilities or required tools. Use --json when you need those fields.
