pdh-android-collector SKILL.md skillA
pdh-android-collector from chainlesschain/chainlesschain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add chainlesschain/chainlesschain/pdh-android-collector@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Build or debug a Personal-Data-Hub collector that pulls a Chinese Android app's data off a rooted phone over ADB. Encodes the real-device rule — prefer on-device plaintext SQLite over fragile web APIs (cookies/signing/endpoints drift; local DBs are stable + sign-free).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PDH 安卓本地采集器构建 (pdh-android-collector) The durable way to collect a Chinese app's data is **reading its on-device plaintext SQLite DBs over ADB+root**, NOT calling its web API. Web APIs drift constantly (cookie schemas, signing salts, endpoint paths, permission codes); the local DBs are stable and need no signing. Reach for a web fetcher only when the data genuinely isn't on-device. Real-device provenance (device 5lhyaqu8lbwstc6x / Xiaomi chopin, 2026-06-11): this recipe cracked Toutiao (uid from `account_db.login_info` when the web profile returned `error_code 16`) and Douyin (`video_record.db` `record_<uid>` = 900 plaintext watch records, sidestepping the SQLCipher IM db). Reference memory `pdh_real_device_findings_2026_06_11` and `pdh_local_db_over_web_api_strategy`. ## Phase 0 — Map the device (always first) ```bash adb devices -l # device + transport adb shell "su -c id" # root (uid=0) — release APKs aren't debuggable adb shell pm list packages -3 # which target apps are installed ``` Map installed packages → adapters in `packages/personal-data-hub/lib/adapters/`. Only …

How to install
mdr add chainlesschain/chainlesschain/pdh-android-collector@sha256:0569989720056580The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
