SessionStart also fires on compact, and the activate hook always reset the flag to the default level. A session switched to /ponytail ultra fell back to full after compaction, and a session stopped with "stop ponytail" was switched back on. Codex fires the same compact source. The activate hook now reads the source from the JSON Claude Code and Codex pipe on stdin, and keeps the live level (or stays off) on compact. Startup, resume and clear still start at the default level. Like the mode tracker, it never waits on stdin for more than a second and falls back to the default level (DietrichGebert#443). The hook entry itself is unchanged: Codex trusts a hook by a hash of its matcher and command, and skips a changed hook until the user approves it again, so a new or edited entry would have dropped the ruleset there.

Thanks! Tested it in Claude Code: on main a real /compact dropped ultra back to full, with this PR it stays ultra, and after "stop ponytail" it stays off. Merged, will be in the next release. |

Problem
SessionStart also fires on compaction (
source: "compact"), and the activate hook always reset the flag to the default level. So:/ponytail ultrafell back tofullafter compaction,Codex fires the same
compactsource.Fix
hooks/ponytail-activate.jsnow readssourcefrom the JSON that Claude Code and Codex pipe on stdin:compact: keep the live level, or stay off if the session was stopped,startup,resume,clear: start at the default level, as before.Like the mode tracker, it never waits on stdin for more than a second, and falls back to the default level (#443).
The hook entry in the manifests is unchanged on purpose: Codex trusts a hook by a hash of its matcher and command, and skips a changed hook until the user approves it again. A new or edited entry would have dropped the ruleset there.
Tests
tests/hooks.test.js: compact keepsultra, compact after "stop ponytail" stays off, startup still resets to the default.tests/hooks-windows.test.js: updated for the stdin read.node scripts/check-rule-copies.jsandnode scripts/check-versions.jspass.Note: on my Windows machine, two failures also show up on an untouched
main:tests/correctness.test.js(pandas one-liner) and the#1032nudge-path assertion attests/hooks.test.js:319, which aborts the rest of that file. I ran the rest ofhooks.test.jswith that one assertion commented out, and it passes. CI on Linux should show the full picture.
