Can a cheap model install and use TayHCode/cdpidletabs?

Newest observation per platform and model. Revisions, runtimes and operations can differ; this is not a ranking. Earlier observations remain in the full history.

Partly checked

Some behavior was checked; the full README workflow was not fully checked.

Answers apply to each recorded setup, revision and operation. Earlier observations remain in Run details.

Does what it says

0 of 1 claims checked out

idle seconds must be at least 1: Real input did not produce the expected result: must be at least 1
Source: `--idle-seconds` accepts integers with a **minimum of 1 second** (default: 600);
Input: 0
Expected: error before endpoint check
Command: python3 close_idle_tabs.py --idle-seconds 0
Observed: must be at least 1

Examples

1 of 1 ran as expected

README quick start help command: command completed successfully
Source: README.md#Install
Input: --help
Expected: usage options
Command: python3 close_idle_tabs.py --help
Observed: TATE_FILE reuse observations here (default: .close_idle_tabs_state.json in the working directory) --close close eligible pages; without this option, only report them --quiet suppress normal reports and unavailable-endpoint notices Always protect the first real page in Chrome's list (usually the most recently active). Internal pages never satisfy this guard; about:blank is a fallback only when there are no real pages. Protected pages restart their idle clock each run.

Agent interfaces

CLI

Observed interfaces were exercised by the checker. Documentation alone does not confirm compatibility.

Tested with

Codex / Luna

macOS: Codex / Luna · agent codex-cli 0.163.0 · Blocked · cause needs diagnosis · Oct 22, 2026 on 484201d7e6b4

Each entry describes its recorded operation and source revision. Other agent clients were not tested.

Safety

No sign of malicious behavior found in these checks

No problems traced to this repository code in these checks; a short run cannot prove safety.
