legacy-webview-implementation

legacy-webview-implementation is a skill for Claude Code, Codex from emilianoeloi/ios-WK-UI-WebView. It costs 33 tokens per session (426 once invoked), scanned A, original, MIT.

A step-by-step implementation guide for changing older Objective-C iPhone and iPad WebView code. It covers both WKWebView and the older UIWebView fallback, plus the JavaScript bridge between the app and web pages.

In plain words
What is it for?
Use it to plan and implement small WebView fixes, preserve existing handler names and message queues, add focused tests, and build the project for verification.
Why use it?
It requires the current behavior and affected files to be understood before editing, which reduces accidental changes to navigation and bridge protocols.

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

legacy-webview-implementation 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 2mo ago.

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.

What it actually says

Legacy WebView Implementation

Purpose

Implement production-safe fixes and enhancements in this legacy iOS WebView project.

Phase 0 — Read (no edits)

  1. Confirm target behavior from README and the current code path
  2. If the runtime flow or bridge contract is unclear, run legacy-webview-analysis first

Gate

  1. State the minimal file touch set before editing. If the request is ambiguous, stop and ask instead of guessing scope.

Phase 1 — Implement

  1. Patch minimally in Objective-C and preserve existing conventions
  2. Keep WKWebView and fallback expectations aligned
  3. Preserve bridge contract (handler names, protocol queue semantics)
  4. Add focused tests when behavior can be isolated

Phase 2 — Validate

  1. Build with the canonical command from AGENTS.md:
xcodebuild -project ios-WK-UI-Webview.xcodeproj \
  -scheme ios-WK-UI-Webview \
  -destination 'generic/platform=iOS Simulator' \
  IPHONEOS_DEPLOYMENT_TARGET=12.0 build
  1. If the build cannot run in your environment, state the limitation explicitly — never claim validation that did not happen

Quality Rules

  • Keep architecture simple and focused on requested behavior
  • Do not change unrelated files or flows
  • Prefer centralized constants over duplicated literals
  • Add comments only for non-obvious bridge/navigation edge cases

Anti-example (do not do)

"While fixing the redirect, I also modernized the delegate wiring and renamed two handlers for clarity."

Unrequested scope. Handler names are a public contract; renames are a migration, not a fix.

Definition of Done

  • Change is scoped and understandable
  • Core navigation/bridge flow remains stable
  • Validation completed (build/test or explicit limitation note)
  • No accidental API or contract breakage
Changes

What this file has done since we first saw it

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.
