# Task Breakdown: Android FS5 Device Management

**Feature**: 001-android-fs5-management
**Created**: 2026-03-02
**Status**: Pending

---

## Phase 1: Project Setup

- [ ] T001 Create project skeleton: `.gitignore`, `.env.example`, `README.md`, `lib/`, `tests/` dirs
- [ ] T002 Create `.env` from `.env.example` with device serial `RD51QE202392`
- [ ] T003 Verify bats-core and shellcheck available (`bats --version`, `shellcheck --version`)

---

## Phase 2: Foundational Library (lib/)

- [ ] T004 Create `lib/output.sh` — `out_human`, `out_json`, `out_error`, `out_success` functions
- [ ] T005 Create `lib/adb.sh` — `adb_check_device`, `adb_cmd`, `adb_get_prop`, `adb_shell`, `adb_log_op`
- [ ] T006 Create `lib/adb.sh` — `adb_push`, `adb_pull` with existence checks and `--force` support

---

## Phase 3: Tests (RED phase — must fail before implementation)

- [ ] T007 [US1] Write `tests/test_status.bats` — tests for `status` command (connected, disconnected, --json)
- [ ] T008 [US2] Write `tests/test_transfer.bats` — tests for push/pull (basic, idempotent, --force, directory)
- [ ] T009 [US3] Write `tests/test_app.bats` — tests for `app list`, `app install`, `app uninstall`
- [ ] T010 [US4] Write `tests/test_shell.bats` — tests for `shell` command passthrough
- [ ] T011 [US5] Write `tests/test_logs.bats` — tests for `logs` command (stream, --lines, --filter, --output)
- [ ] T012 Verify ALL tests FAIL (RED phase confirmed) before writing `fs5` entrypoint

---

## Phase 4: Implementation — P1 User Stories

- [ ] T013 [US1] Create `fs5` entrypoint: argument parsing, `--help`, config loading, `status` command
- [ ] T014 [US1] Implement `status` command: collect device props, battery, storage, format human + JSON output
- [ ] T015 [US2] Implement `push` command: file existence check, transfer, idempotency guard, logging
- [ ] T016 [US2] Implement `pull` command: device file check, transfer, local overwrite guard, logging
- [ ] T017 Verify T007 + T008 tests PASS (GREEN phase for P1)

---

## Phase 5: Implementation — P2 User Stories

- [ ] T018 [US3] Implement `app list` command: parse `pm list packages`, filter system/user, version lookup
- [ ] T019 [US3] Implement `app install` command: APK validation, `adb install`, package name confirmation
- [ ] T020 [US3] Implement `app uninstall` command: `--force` guard, `pm uninstall`, logging
- [ ] T021 [US4] Implement `shell` command: passthrough to `adb shell`, stdin pipe support
- [ ] T022 Verify T009 + T010 tests PASS (GREEN phase for P2)

---

## Phase 6: Implementation — P3 User Stories

- [ ] T023 [US5] Implement `logs` command: `adb logcat` stream, `--lines` (dump mode), `--filter`, `--output`
- [ ] T024 Verify T011 tests PASS (GREEN phase for P3)

---

## Phase 7: Polish & Quality Gates

- [ ] T025 [P] Run `shellcheck fs5 lib/adb.sh lib/output.sh` — fix all warnings to zero
- [ ] T026 [P] Run full test suite `bats tests/` — all tests must pass
- [ ] T027 [P] Write `README.md` with installation, usage examples, and quickstart scenarios
- [ ] T028 Validate all 8 quickstart scenarios from `plan.md` manually against live device
- [ ] T029 Initial git commit: `feat: add android-fs5 CLI toolset`
