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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.02108 |
| Opus 5 | $0.00036 | $0.01054 |
| Sonnet 5 | $0.00014 | $0.00422 |
| Haiku 4.5 | $0.00007 | $0.00211 |
Grade A, and why
firebase-apk-scanner scanned grade A with 1 finding 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 5d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Local tools `apktool`, `curl`, `jq`, `grep`, `unzip`, and `strings` (binutils). Required; `sed`/`awk` helpful. How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile backend APK scanner
Contract
| Field | Bound contract |
|---|---|
| Trigger | Authorized user needs to assess mobile-backend exposure from compiled Android APKs by extracting backend configuration and probing discovered endpoints for misconfiguration. |
| Authority | Human-only. Runs only on explicit human invocation. Before any probe that mutates remote state, present the target endpoints and the exact probe mutations and get operator confirmation. Do not test any APK or backend project without written authorization for it. |
| Side effect | Remote mutation of discovered backend endpoints (authentication, database, storage, cloud functions, remote config) limited to one small, uniquely named probe artifact per test that is deleted before reporting. No bulk writes and no deletion of pre-existing data. |
| Done | Every APK is classified as tested, failed, or no-config; every created probe artifact is deleted and verified gone; findings include evidence and remediation. |
Inputs
- One or more APK paths (a single
.apkfile or a directory of.apkfiles). Required. - Written authorization covering each APK and the backend project(s) it references. Required before any probe; an APK without it is not scanned.
- Local tools
apktool,curl,jq,grep,unzip, andstrings(binutils). Required;sed/awkhelpful. - A working directory for decompiled output. Optional; removed at the end unless the operator asks to keep it.
- Known function names or collection names to prioritize. Optional.
Procedure
- Validate input at the trust boundary. Confirm each path exists; expand a directory argument to its
.apklist; if the list is empty, ask the operator for a path and stop. For each APK, confirm written authorization for the app and its backend project. An APK missing authorization is classifiedfailedwith reasonnot-authorizedand skipped. Done when: every APK path is confirmed, authorization is verified, and unauthorized APKs are classifiedfailed.
What ships with it
1 file 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.

firebase-apk-scanner is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 4d ago), licensed Apache-2.0. It adds 72 tokens to every session and 2,108 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
