TayHCode/t3-done-notify

No problems traced to this repository code in these checks.

OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.

A short run cannot establish that code is safe.

Connections show IP addresses; proxies can hide the final hostname.

Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.

macos behavior observation needs an OS-native file/network/process collector; only the static scan ran.

No Linux syscall trace was collected.

Full safety evidence →

• One-shot run reads enabled sources and reports a completed poll without sending webhooks: Real input produced the expected result: poll complete

  Source: Run once without making webhook requests:

  Input: --once --dry-run against the fixture Claude Code session tree

  Expected: prints 'poll complete' and exits 0

  Command: <guest-path> <guest-path> --once --dry-run

  Observed: poll complete

Examples

• Installer unit tests (run with the installed venv interpreter): command completed successfully

  Source: CONTRIBUTING.md

  Input: python -m unittest discover -s tests -p test_install.py -q, TMPDIR on /private/tmp

  Expected: installer tests pass

  Command: <guest-path> -m unittest discover -s tests -p test_install.py -q

  Observed: ---------------------------------------------------------------------- Ran 5 tests in 10.722s OK

Cycles

• Each polling cycle scans sources and then sleeps for the poll interval: Triggered one cycle by hand (run-once: --once runs exactly one loop iteration and returns before the sleep; normal trigger: continuous loop every T3_DONE_POLL_SECONDS (default 60)): poll complete

  Source: t3_done_notify.py

  Input: fixture Claude Code session tree; no webhook contacted

  Expected: one 'poll complete' line and exit 0

  Command: <guest-path> <guest-path> --once

  Observed: poll complete

Local or hosted: local

Install t3-done-notify per README, then run the documented one-shot poll (--once --dry-run) against a fixture session tree.
