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 | $0.00034 | $0.00921 |
| Opus 5 | $0.00017 | $0.00461 |
| Sonnet 5 | $0.00007 | $0.00184 |
| Haiku 4.5 | $0.00003 | $0.00092 |
Grade A, and why
hermes-apk-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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hermes+ Android Workspace Integrity Skill
This skill implements the canonical GEMINI.md contract for authorized Android workspace analysis and transformation. It is complementary guidance; when it differs from GEMINI.md, the root workspace contract is authoritative.
Evidence-first workflow
| Stage | Action | Required evidence |
|---|---|---|
| Decode | Run decompile_apk into a dedicated workspace. |
Input path/hash, package, SDK values, manifest path, Smali roots, and ABI directories. |
| Analyze | Run analyze_injection_surface without workspace mutation. |
Application/activity/JNI/Flutter findings, native .so libraries, security analysis (anti-debug, root checks, SSL pinning, obfuscators), multi-dex roots, warnings, and candidate hooks. |
| Prepare | Build or validate the Flutter payload. | ABI coverage, native libraries, assets, build mode, engine identity, and warning set. |
| Integrate | Run inject_flutter_runtime_and_smali only after selecting a supported mode. |
Generated descriptors, changed files, register/lifecycle evidence, and warnings. |
| Configure | Run patch_manifest_and_config for reviewed manifest changes. |
Exact component, permission, application, and rendering deltas. |
| Verify | Run recompile_align_and_sign as the final output step. |
Build, alignment, signature, certificate context, output path, and artifact classification. |
Deep reverse engineering & security audit
- Anti-debugging & Root Detection: Review
securityAnalysisresults (isDebuggerConnected,RootBeer,subinaries,test-keys,TracerPid). Ensure injected Smali execution paths do not trip host tamper mechanisms. - Native Libraries & ABI Parity: Inspect
nativeLibrariesmapping per ABI before payload synthesis. Ensure injected Flutter libraries match the target's native architectures. - Multi-DEX Integrity: Resolve classes and methods across all
smali_classes*directories. Never assume a single primarysmali/root in modern applications.
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.

hermes-apk-reverse-engineering is a skill published in the GitHub repository MarwanDevSpace/mcp-flutter-apk-injector (5 stars, last pushed 9d ago), licensed MIT. It adds 34 tokens to every session and 921 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.
