safari-extension-control-workflow

safari-extension-control-workflow is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 91 tokens per session (2,229 once invoked), scanned A, original, Apache-2.0.

A decision guide for connecting a macOS app with Safari through the available extension types and Safari services. It covers communication between the app, extensions, and web pages.

In plain words
What is it for?
Use it when a Mac app must extend Safari, exchange messages with a Safari extension, inspect web pages, inject scripts, block content, or open Safari-related views.
Why use it?
It helps choose the correct Safari integration before implementation, avoiding an extension type or control method that cannot support the intended behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

safari-extension-control-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Safari Extension Control Workflow

Purpose

Guide Safari integration work for macOS apps, with enough platform awareness to choose the right Safari extension or SafariServices surface before implementation starts.

This skill owns the decision between Safari Web Extensions, Safari Web Inspector Extensions, Safari App Extensions, content blockers, SafariServices APIs, app-to-extension messaging, and limited external automation paths. It is not a generic browser-extension guide and it is not a replacement for xcode-build-run-workflow or xcode-testing-workflow.

When To Use

  • Use this skill when the user wants a macOS app to extend Safari, communicate with Safari content, or coordinate native app state with a Safari extension.
  • Use this skill when choosing between a Safari Web Extension, Safari Web Inspector Extension, Safari App Extension, Safari content blocker, SFSafariApplication, SFSafariExtensionManager, SFSafariViewController, ASWebAuthenticationSession, AppleScript, Shortcuts, or URL-opening behavior.
  • Use this skill when the work involves WebExtension manifests, Web Inspector developer-tool panels, native messaging, app groups, injected scripts, toolbar items, content blockers, Safari profiles, temporary extension loading, unsigned extension testing, or App Store distribution.
  • Use this skill when a user says they want to "control Safari" from a Mac app and the first job is distinguishing supported SafariServices control from broader GUI or scripting automation.
  • Recommend explore-apple-swift-docs when the user primarily needs direct Apple documentation lookup rather than integration-shape guidance.
  • Recommend xcode-build-run-workflow when the next step is target setup, build settings, entitlements, signing, file membership, running the containing app, or guarded Xcode project mutation.
  • Recommend xcode-testing-workflow when the next step is repeatable XCTest, XCUITest, extension-state checks, or test-plan work.
  • Recommend swiftui-app-architecture-workflow when the Safari work is settled and the remaining question is native app scene, command, focus, or settings structure.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
