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 | $0.00504 | $0.00504 |
| Opus 5 | $0.00252 | $0.00252 |
| Sonnet 5 | $0.00101 | $0.00101 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
ios-WK-UI-WebView copilot-instructions.md 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 9d 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.

Copilot Instructions
Project Intent
This repository is an iOS legacy playground (Objective-C, circa iOS 8/9 era) created to explore:
WKWebViewconfiguration and lifecycleUIWebViewfallback behavior- ObjC <-> JS communication using
WebViewJavascriptBridgeandWKWebViewJavascriptBridge
Primary source of truth for scope is the root README.md and existing code under ios-WK-UI-Webview/.
Workflow Rules
- Keep changes minimal and localized in legacy code.
- Prefer Objective-C patterns already used in the project.
- Do not introduce SwiftUI, Combine, or large architectural rewrites unless explicitly requested.
- Keep public bridge APIs and protocol constants backward compatible.
- Validate behavior through flow reasoning around load lifecycle and delegate callbacks.
Guardrails For This Codebase
- Treat
WebViewJavascriptBridge.js.txtandWebViewJavascriptBridgeBase.*as a protocol pair. - Preserve
wvjbschemeand queue host semantics unless migration is explicitly requested. - Be careful with observer/delegate lifecycle (avoid leaks/crashes from KVO or delegate replacement).
- Maintain fallback pathways when editing WebView controllers.
- Keep
Constants.hvalues centralized; avoid scattering literals.
Quality Baseline
- Changes should compile in Objective-C context (no mixed-language assumptions).
- The canonical build command (with the deployment-target override modern Xcode requires) lives in
AGENTS.md. - Prefer focused unit tests when touching parsing, routing, or bridge message transformations.
- Add comments only where behavior is subtle (navigation edge cases, bridge queue logic).
- Keep naming stable and explicit for maintainability in an old codebase.
Communication Efficiency
Default tone is concise.
Rules:
- Skip affirmations and filler
- Respond directly
- No long summaries unless requested
- Keep explanations practical and code-linked
For maximum token compression, load skills/concise-output/SKILL.md.
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.

ios-WK-UI-WebView copilot-instructions.md is an instructions file published in the GitHub repository emilianoeloi/ios-WK-UI-WebView (3 stars, last pushed 2mo ago), licensed MIT. It adds 504 tokens to every session, about $0.0025 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.
