Auto-generated metadata

When you create a new script, Page Proxy generates this template:

import { pa, pn, pq, ps, pt, pv } from "@page-proxy/pp";

// ==Page Proxy==
// @title Page Proxy
// @website http://currentwebsite.domain/*
// @description
// @author
// @grant
// ==/Page Proxy==

// ==Selectors==
// ==/Selectors==

I will often omit the metadata in code examples, but they are required.

What each metadata line does​

// ==Page Proxy== and // ==/Page Proxy==​

  • These mark the start and end of the metadata block.
  • The editor validates this block before running or saving.

@title​

  • Required field.
  • Script display name shown in the UI.
  • Used to generate the exported file name.

Example:

// @title Highlight premium cards

@website​

  • Required field.
  • Website glob used to decide where the script applies.
  • Must match the active tab URL when saving.
  • If left blank, Page Proxy auto-fills it from the current page when possible.

Example:

// @website https://example.com/*

@description​

  • Required field.
  • Human-readable summary shown in metadata/export views.
  • Can be empty text, but the field line must exist.
  • Supports multiline values (see below).

Example:

// @description Adds a badge to newly loaded cards.

@author​

  • Optional field.
  • Shown in metadata/export views.

Example:

// @author Jane Doe

@credits​

  • Optional field.
  • Used for attribution (libraries, snippets, contributors).
  • If empty, it may be hidden in parts of the UI.
  • Supports multiline values (see below).

Example:

// @credits Inspired by internal design-system selectors.

@grant​

  • Optional field.
  • Grants are comma-separated (spaces and commas are both accepted separators).
  • Supported values:
    • run-on-page-load
  • run-on-page-load enables page-load execution after permission is granted from the Help tool.

Example:

// @grant run-on-page-load

Multiline metadata example​

@description and @credits support multiline values.

Add continuation lines directly below the metadata key line:

// ==Page Proxy==
// @title Product card tweaks
// @website https://shop.example.com/*
// @description Improve readability for dense product cards.
// Increase spacing between title and pricing rows.
// @author Jane Doe
// @credits UI idea from internal design review.
// Selector strategy adapted from old userscript experiments.
// ==/Page Proxy==

Metadata parsing rules​

  • Each metadata line must use // @key value (a colon like @key: value is also accepted).
  • Required fields are @title, @website, and @description.
  • Optional fields are @author, @credits, and @grant.
  • Multiline continuation lines are supported only for @description and @credits.
  • A multiline field continues until the next metadata key (next // @... line).
  • Duplicate supported fields (for example two @website lines) are invalid.
  • @grant values must be supported grant names.
  • Unknown metadata keys are ignored.

About // ==Selectors==​

  • This block is separate from metadata, but also required by the editor.
  • Place selector definitions between:
    • // ==Selectors==
    • // ==/Selectors==
