quick() and dry_run() previously trusted the stored category from tracked.json without re-validating at delete time. Stale entries from before #34840 could carry category="cron-output" for cron control-plane paths (e.g. cron/jobs.json), causing quick() to delete the live scheduler registry. Fix: - Fix guess_category() to only classify cron/output/** as cron-output (was classifying ALL cron/* paths, missing the #34840 fix). - Re-validate cron-output entries via guess_category() at delete time in quick() and dry_run(); stale entries that are no longer classified as cron-output are skipped and removed from tracked.json. - Add _is_protected_cron_path() as a hard defense-in-depth guard that blocks deletion of cron/cronjobs directories and known control-plane files (jobs.json, .tick.lock) regardless of stored category. - Update test_cron_subtree_categorised to match fixed guess_category (only cron/output/* is cron-output, not all of cron/). Tests: add 5 regression tests in TestStaleCronEntryMigration.
disk-cleanup
Auto-tracks and cleans up ephemeral files created during Hermes Agent
sessions — test scripts, temp outputs, cron logs, stale chrome profiles.
Scoped strictly to $HERMES_HOME and /tmp/hermes-*.
Originally contributed by @LVT382009 as a
skill in PR #12212. Ported to the plugin system so the behaviour runs
automatically via post_tool_call and on_session_end hooks — the agent
never needs to remember to call a tool.
How it works
| Hook | Behaviour |
|---|---|
post_tool_call |
When write_file / terminal / patch creates a file matching test_*, tmp_*, or *.test.* inside HERMES_HOME, track it silently as test / temp / cron-output. |
on_session_end |
If any test files were auto-tracked during this turn, run quick cleanup (no prompts). |
Deletion rules (same as the original PR):
| Category | Threshold | Confirmation |
|---|---|---|
test |
every session end | Never |
temp |
>7 days since tracked | Never |
cron-output |
>14 days since tracked | Never |
| empty dirs under HERMES_HOME | always | Never |
research |
>30 days, beyond 10 newest | Always (deep only) |
chrome-profile |
>14 days since tracked | Always (deep only) |
| files >500 MB | never auto | Always (deep only) |
Slash command
/disk-cleanup status # breakdown + top-10 largest
/disk-cleanup dry-run # preview without deleting
/disk-cleanup quick # run safe cleanup now
/disk-cleanup deep # quick + list items needing prompt
/disk-cleanup track <path> <category> # manual tracking
/disk-cleanup forget <path> # stop tracking
Safety
is_safe_path()rejects anything outsideHERMES_HOMEor/tmp/hermes-*- Windows mounts (
/mnt/cetc.) are rejected - The state directory
$HERMES_HOME/disk-cleanup/is itself excluded $HERMES_HOME/logs/,memories/,sessions/,skills/,plugins/, and config files are never tracked- Backup/restore is scoped to
tracked.json— the plugin never touches agent logs - Atomic writes:
.tmp→ backup → rename
