ios-decompile

ios-decompile is a command for Claude Code from gyh20062008-commits/re-ios. It costs 14 tokens per session (435 once invoked), scanned A, original, MIT.

A command that runs an authorized, offline examination of an iOS app file and creates an analysis report. It checks dependencies, unpacks the target, fingerprints it, scans its binary and APIs, and summarizes the findings.

In plain words
What is it for?
Use it to analyze an IPA, app bundle, or other authorized iOS artifact and save the results in a chosen output directory.
Why use it?
It turns a sequence of inspection steps into one repeatable command. It also makes encryption or other analysis limits explicit instead of silently bypassing them.

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

ios-decompile 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.

What it actually says

Authorized iOS Static Analysis

Use the ios-reverse-engineering skill.

Arguments:

  • $1: authorized iOS target artifact.
  • $2: optional output directory. Default: ios_analysis_out.

Safety boundary:

  • Confirm the user is asking for authorized static analysis.
  • Do not bypass FairPlay DRM or app encryption.
  • Do not steal credentials, tokens, cookies, or account data.
  • Do not attack, fuzz, replay, probe, or validate discovered real services.
  • If the binary appears encrypted, report the limitation and ask for an authorized debug, enterprise, decrypted, or source-derived build.

Workflow:

  1. Resolve the plugin script directory for skills/ios-reverse-engineering/scripts.
  2. Run check_deps.sh.
  3. Run ios_unpack.sh "$TARGET" "$OUTDIR".
  4. Run ios_fingerprint.sh "$TARGET" "$OUTDIR".
  5. Run ios_macho_analyze.sh "$TARGET" "$OUTDIR".
  6. Run ios_class_scan.sh "$OUTDIR".
  7. Run ios_api_scan.py "$OUTDIR".
  8. Run ios_report.py "$OUTDIR".
  9. Summarize the report path and key limitations.

Suggested shell sequence once SCRIPT_DIR, TARGET, and OUTDIR are resolved:

"$SCRIPT_DIR/check_deps.sh"
"$SCRIPT_DIR/ios_unpack.sh" "$TARGET" "$OUTDIR"
"$SCRIPT_DIR/ios_fingerprint.sh" "$TARGET" "$OUTDIR"
"$SCRIPT_DIR/ios_macho_analyze.sh" "$TARGET" "$OUTDIR"
"$SCRIPT_DIR/ios_class_scan.sh" "$OUTDIR"
"$SCRIPT_DIR/ios_api_scan.py" "$OUTDIR"
"$SCRIPT_DIR/ios_report.py" "$OUTDIR"

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.
