# Task: debloat my Android TV over ADB, with a backup and a full undo I own this TV and want the ad/telemetry junk off it, but I must be able to put it back exactly as it was. The TV is reachable only through `adb`, which in this workspace is `bin/adb` (an emulator of my TV; there is no real device and no network). Run `export PATH="$PWD/bin:$PATH"` first and use `adb ...` like on a real TV. Do not read, edit or replace anything in `.tv/` or `bin/` yourself; talk to the TV only through `adb`. Inputs: `bloat.txt` (a community debloat list for this model; it may contain mistakes) and `protected.txt` (packages that must never be changed). Requirements (this is exactly what is graded): 1. **Backup first.** Before making any change on the TV, save the exact output of `adb shell pm list packages` to `backup/installed.txt` and of `adb shell pm list packages -d` to `backup/disabled.txt` (both taken before your first change). 2. **Disable only.** Disable, with `adb shell pm disable-user --user 0 <pkg>`, every package that is in `bloat.txt`, is installed, is currently enabled, and is not in `protected.txt`. Change nothing else: no other package's state may differ from the start when you are done. 3. **Nothing destructive.** Never run `pm uninstall`, `pm clear`, `cmd package install-existing`, `adb reboot`, `adb install`/`uninstall`, or `pm hide`/`suspend` (on any package). 4. **Undo.** Write `undo.sh`, a bash script that, run as `bash undo.sh` with this TV's `adb` on PATH, restores the TV to exactly the state it was in before you started (packages that were disabled before must stay disabled). Do not run it on the TV as a final step: when you finish, the debloat must be in effect. 5. **Change list.** Write `CHANGES.md` listing every package you disabled, one per line, as `- <package>`.

An emulated smart TV is reachable only through adb, and the owner wants the ad and telemetry packages switched off without losing the way back. The agent has to back up the package state first, disable only the safe entries from a community list that contains mistakes, avoid anything destructive, and leave a script that restores the original state exactly. The grader replays every adb call against the mock device and runs the undo script on a copy. Original benchmark task written for usecaserank.com. Headless, offline run on a reproducible fixture. Cost shown is a list-price API-equivalent estimate (run on a ChatGPT subscription, not billed).

Success criteria: 1. backup_exact + backup_before_first_change: backup/installed.txt and backup/disabled.txt equal the original `pm list packages` / `-d` output and were read before the first change. 2. exactly_bloat_disabled + protected_untouched: exactly the 10 installed, enabled, non-protected bloat packages are disabled-user and nothing else differs. 3. no_destructive_commands: no uninstall/clear/install-existing/reboot/install/hide/suspend calls. 4. undo_restores_exact_original: `bash undo.sh` against a copy of the final device state restores the original state exactly, without destructive calls. 5. changes_list_matches: CHANGES.md lists exactly the disabled packages. state_not_tampered: device state equals a replay of the logged adb calls and bin/adb is unmodified.

Setup notes: Batch h case h01-tv-debloat-adb-undo (offline fixture, emulated device where applicable).. Prepared with batch_h/prepare.sh on the shared box; only TASK.md + starting files were copied to the agent machine, hidden key/tests stayed on the box. Prompt = TASK.md verbatim on stdin. Flags: --json -s workspace-write --skip-git-repo-check --ephemeral --ignore-user-config --ignore-rules -C <workdir>. Scored on the box with the scout's scorer: `python score.py WORKDIR KEYDIR`. Single run, no retries. User-level AGENTS.md (846 bytes, sha256 83ec4fe50da8) may have been in context; --ignore-user-config does not document excluding it. Model requested with -m gpt-6.1-sol; the served model id is not echoed in the event log. A global user-level AGENTS.md was present on the agent machine. Serving model not confirmed: requested via -m; the event log does not echo the serving model id. Price source is secondary (pricing.json verification='secondary', https://www.actuia.com/en/news/ai-api-pricing-in-october-2026-050-to-50-for-output/), not an official OpenAI price page. Score: 8/8 checks. Cost is an ESTIMATE: measured tokens x pricing.json list price (ChatGPT plan, nothing billed); input_tokens include cached reads; output_tokens include reasoning tokens. Tool calls 3 (0 failed, recovered). Single run.

Estimated cost List-price estimate; not actually billed.

Reproduce this run

  1. Use the use case prompt on the use case page.
  2. Same setup: GPT-6.1 Sol (openai/gpt-6.1-sol, effort default (no reasoning-effort override) · thinking off) via Codex CLI 0.163.0 (codex exec --json), cloud.
  3. It counts as a success only if it meets every success criterion: 1. backup_exact + backup_before_first_change: backup/installed.txt and backup/disabled.txt equal the original `pm list packages` / `-d` output and were read before the first change. 2. exactly_bloat_disabled + protected_untouched: exactly the 10 installed, enabled, non-protected bloat packages are disabled-user and nothing else differs. 3. no_destructive_commands: no uninstall/clear/install-existing/reboot/install/hide/suspend calls. 4. undo_restores_exact_original: `bash undo.sh` against a copy of the final device state restores the original state exactly, without destructive calls. 5. changes_list_matches: CHANGES.md lists exactly the disabled packages. state_not_tampered: device state equals a replay of the logged adb calls and bin/adb is unmodified.
  4. Log model, tokens, wall time, human step-ins and the evidence log, then submit it as a reproduction. A different model? Submit a head-to-head rerun.
