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 | $0.00123 | $0.00689 |
| Opus 5 | $0.00062 | $0.00345 |
| Sonnet 5 | $0.00025 | $0.00138 |
| Haiku 4.5 | $0.00012 | $0.00069 |
Grade A, and why
competition-ios-runtime 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.
This is a copy
100% identical to competition-ios-runtime — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Competition iOS Runtime
Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.
Use this skill when the decisive path runs through live iOS trust boundaries rather than static strings or plist values alone.

Quick Start
- Preserve the original IPA, extracted bundle, and any decrypted or re-signed copy as separate artifacts.
- Start with
Info.plist, entitlements, URL schemes, frameworks, Keychain usage, and local app storage before broad runtime hooks. - Choose the narrowest runtime boundary that proves behavior: signer, trust evaluator, Keychain accessor, Objective-C or Swift method, or network request builder.
- Correlate static bundle evidence and live hook output before claiming the trust path is understood.
- Reproduce the accepted request, token, or gated branch from the smallest hook set.
Workflow
1. Static iOS Triage
- Map bundle structure,
Info.plist, entitlements, URL schemes, universal links, embedded frameworks, and app group paths. - Record likely trust boundaries: request signers, device binding, certificate checks, jailbreak checks, Keychain access, or local cache loading.
- Note whether sensitive logic sits in Objective-C, Swift, embedded frameworks, or a bundled web surface.
2. Hook The Runtime Boundary
- Prefer hooking request builders, crypto helpers, trust evaluators, Keychain reads, or Objective-C selectors instead of broad UI handlers.
- Record plaintext inputs, headers, nonces, signed strings, and outputs at the boundary that changes server acceptance.
- Patch or bypass pinning or environment checks only enough to expose the real request path.
3. Replay The Accepted Path
- Rebuild the smallest stateful sequence: local token, device identifier, request body, signature, headers, and trust checks.
- Keep hook logs, bundle paths, plist keys, and local storage artifacts tied to the same session or account state.
- If the task becomes mostly about transform recovery instead of iOS runtime, switch back to the broader crypto or mobile skill.
What ships with it
2 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.
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.

competition-ios-runtime is a skill published in the GitHub repository Asaiuta/reverse-workbench-skill (2 stars, last pushed 21d ago), licensed MIT. It adds 123 tokens to every session and 689 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to competition-ios-runtime, differing in 0 lines, and is treated as a copy.
