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 | $0.00321 | $0.09024 |
| Opus 5 | $0.00161 | $0.04512 |
| Sonnet 5 | $0.00064 | $0.01805 |
| Haiku 4.5 | $0.00032 | $0.00902 |
Grade A, and why
ios-reverse-engineering 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 4d 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.

iOS Reverse Engineering
Extract and analyze iOS IPA files, .app bundles, Mach-O binaries, dynamic libraries, and frameworks using ipsw (blacktop/ipsw), otool, strings, radare2/rizin, and Ghidra headless. Trace call flows through application code, analyze security patterns, deep-scan for cloud provider credentials (Firebase, GCP, AWS, Azure), perform LLM-assisted binary reversing with decompilation and Ghidra headless scripts, fingerprint embedded third-party SDKs with version detection and CVE cross-referencing, and detect anti-tampering protections (obfuscation tools, anti-debugging, dylib injection prevention, integrity checks, jailbreak detection). Produce structured documentation of extracted APIs and security findings. Works with both Swift and Objective-C applications.
Prerequisites
This skill requires ipsw (which includes class-dump functionality and much more) and, on macOS, the standard developer tools (otool, strings, plutil, codesign) via Xcode Command Line Tools. For deep binary analysis, radare2 (or rizin) is recommended; Ghidra headless is optional for advanced decompilation. On Linux, ipsw provides cross-platform Mach-O analysis, entitlements, class-dump and thinning; libplist/plistutil (or python3 plistlib) provide plist parsing; binutils provides strings/nm. otool/codesign/plutil/PlistBuddy/lipo are macOS-only and the scripts fall back to ipsw/plistutil/python3 automatically — no macOS tools required on Linux. Run the dependency checker to verify:
bash ${CLAUDE_PLUGIN_ROOT}/skills/ios-reverse-engineering/scripts/check-deps.sh
If anything is missing, follow the installation instructions in ${CLAUDE_PLUGIN_ROOT}/skills/ios-reverse-engineering/references/setup-guide.md.
Workflow
Phase 1: Verify and Install Dependencies
Before analyzing, confirm that the required tools are available — and install any that are missing.
Action: Run the dependency check script.

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-reverse-engineering is a skill published in the GitHub repository incogbyte/iOS-reverse-engineering-claude-skill (88 stars, last pushed 2mo ago), licensed Unlicense. It adds 321 tokens to every session and 9,024 once invoked, about $0.0016 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 2026-08-30.
