Hide distractions with a focus policy

Focus is the part of a package that acts on the live site instead of on a capture. While someone follows one of your feeds, the browser extension applies the policy on the URLs it names: hiding elements, or replacing a feed with a Fruitful panel. It never runs package code.

Declare a policy

"focus": [
  {
    "id": "newsfeed-focus",
    "feeds": ["newsfeed"],
    "urls": [
      { "pattern": { "hostname": "linkedin.com", "pathname": "/feed" } },
      { "pattern": { "hostname": "*.linkedin.com", "pathname": "/feed/*" } }
    ],
    "hide": [
      "linkedin.com##aside.scaffold-layout__aside",
      "linkedin.com##.feed-right-rail",
      "linkedin.com##section:has(h2:has-text(/^LinkedIn News$/i))"
    ]
  }
]

• feeds lists route ids. The policy is active only while the feed on one of those routes is followed by an installed package.
• urls are browsing URLs, distinct from capture routes. Cover the hostname variants people actually visit.
• hide is a list of cosmetic rules in adblock syntax, applied by the extension's cosmetic engine. domain##selector is the common form; :has() and :has-text() are available.

Scope it

Hide what competes for attention, not what the person came for: sidebars, recommendation rails, trending modules, notification badges. Leave navigation, search, and the person's own content alone. A policy that hides too much gets disabled by the user and stops protecting them.

Write one policy per route whose feed people follow. Policies are independent; a person who follows two feeds on one site gets both.

Test it

Load the package into the extension locally and visit the URLs; see Test focus in the extension. Cosmetic rules are cheap to change and do not affect the capture pipeline, so iterate freely.
