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

webview-legacy-reference 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

WebView Legacy Reference

Purpose

Turn this repository into a practical knowledge base for Apple WebView legacy topics with positive framing:

  • historical evolution
  • practical usage patterns
  • migration decision support
  • safe maintenance guidance

When To Use

Use this skill when requests involve:

  1. historical context of UIWebView and WKWebView
  2. best practices for navigation, delegation, and bridge contracts
  3. migration strategy in legacy Objective-C codebases
  4. repository-level guidance for maintainers and learners

Required Output

  1. Explain context with historical timeline and current relevance
  2. Link recommendation to concrete references in references/
  3. Distinguish learning/demo advice from production-critical advice
  4. Provide safe next steps for this repository architecture

Rules

  • Use positive language for the term legacy: stable, battle-tested, and educational value
  • Do not treat legacy as obsolete without context
  • Always highlight compatibility and risk management
  • Keep bridge protocol semantics explicit when cited
  • Ground historical and behavioral claims in the files under references/; if a claim is not covered there, mark it not in references and cite an official Apple/WebKit source instead of asserting it from memory

Reference Index

  • references/uiwebview.md
  • references/wkwebview.md
  • references/webview-javascript-bridge.md
  • references/migration-playbook.md
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
