Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.00336 |
| Opus 5 | $0.00022 | $0.00168 |
| Sonnet 5 | $0.00009 | $0.00067 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
legacy-webview-analysis 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 11d 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 Analysis
Purpose
Use this skill to understand and document the real runtime behavior of the project before changing code.
Required Output
- Objective and scope
- What the app demonstrates according to README and code
- Which flow is being analyzed (WK, UI fallback, bridge, sharing)
- Runtime map
- Entry controller(s)
- Delegate chain
- Navigation/load lifecycle
- Observer interactions
- Bridge contract map
- Handler registration points
- Handler call points
- Queue protocol and JS bridge file coupling
- Risk points
- Crash risks (KVO/delegate lifecycle)
- Behavioral regressions (redirect/share/forward)
- Backward compatibility risks
- Safe patch checklist
- Minimal file touch set
- Verification strategy
- Rollback considerations
Rules
- Always cite concrete files/symbols
- Every technical claim must be verifiable in files read during this analysis
- If the information does not exist in the code, write
not found— do not fill gaps with assumptions - No rewrite proposals by default
- No implementation in analysis-only tasks
Anti-example (do not produce)
"The bridge probably uses evaluateJavaScript under the hood, so the change should be safe."
Speculation without a citation. Either point to the exact call site in WKWebViewJavascriptBridge.m or write not found.
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.

legacy-webview-analysis is a skill published in the GitHub repository emilianoeloi/ios-WK-UI-WebView (3 stars, last pushed 2mo ago), licensed MIT. It adds 43 tokens to every session and 336 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
