What it does
Browserenginekit is an agent skill from dpearson2699/swift-ios-skills. Build alternative browser engines using BrowserEngineKit. Use when developing a non-WebKit browser engine for iOS/iPadOS in supported regions, managing web content/rendering/networking extension processes, configuring GPU and networking process capabilities, checking alternative-engine device eligibility, or reviewing BrowserEngineKit entitlements and Info.plist setup.
Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/browserenginekit-patterns.md`).
It sits in Mobile. It works with iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Developing a non-WebKit browser engine for iOS/iPadOS in supported regions
- Managing web content/rendering/networking extension processes
- Configuring GPU and networking process capabilities
- Checking alternative-engine device eligibility
Example prompts
- “/browserenginekit”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Host launches web content, networking, and rendering extensions
- Host creates XPC connections to each extension
- Host requests anonymous XPC endpoints from networking and rendering
- Host sends both endpoints to the web content extension via a bootstrap
- Web content extension connects directly to networking and rendering
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
sosumi.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Browserenginekit loads about 4.5k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 1,359 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,359 words (~4,451 tokens).
“Framework for building web browsers with alternative (non-WebKit) rendering engines on iOS and iPadOS. Provides process isolation, XPC communication, capability management, and system integration for browser apps that implement their own HTML/CSS/JavaScript engine. Examples target Swift 6.3 and current Apple…”
