Skill: check_recent_chat.sh Script

What It Does

Determines if there were chat messages in the last 3 hours to decide whether to run full dream task.

Script Location

~/.hermes/scripts/check_recent_chat.sh

Performance Issue (2026-05-04) — FIXED

  • Original: stat loop over 162 files took 31 seconds
  • Fixed: Replaced with find -mmin -180 — now 0.062 seconds (500x faster)
  • Script works correctly (returns RECENT_CHAT when files are recent)

Fix Applied (2026-05-04 06:xx)

# Before (slow):
for f in "$DIR"/*.jsonl "$DIR"/sessions/*.jsonl; do
    MTIME=$(stat -c %Y "$f" 2>/dev/null)
    ...
 
# After (fast):
if find ~/.hermes/sessions -name "*.jsonl" -mmin -180 2>/dev/null | grep -q .; then

sqlite3 Issue

  • sqlite3 CLI not available in Termux (only libsqlite library)
  • hermes.db is 0 bytes (empty)
  • Script’s sqlite3 branch fails silently → falls through to file-based check
  • This is fine as long as recent jsonl files exist

If Script Approaches 120s Timeout

RESOLVED (2026-05-04): Fix applied — find -mmin is 500x faster

Verified Working

# After fix (2026-05-04 06:xx):
$ time bash ~/.hermes/scripts/check_recent_chat.sh
NO_RECENT_CHAT
real    0m0.062s   # was 31s — 500x faster

ROOT CAUSE FOUND (2026-05-05) — Bug in scheduler.py Line 482 ✅

The bug is in _run_job_script() in scheduler.py — missing script path in command!

The Bug

When shebang is #!/usr/bin/env bash and shutil.which("bash") succeeds:

cmd = [binary]  # WRONG — missing script path!

So bash runs with no arguments and hangs waiting for stdin → 120s timeout.

The Fix

cmd = [binary, str(path)]  # CORRECT — includes script path

Symptom History

TimeStatus
09:xx Apr1st timeout
12:xx Apr2nd timeout
15:xx Apr3rd timeout
18:01 Apr 304th timeout
21:01 May 45th timeout
00:02 May 56th timeout (THIS RUN)

Root Cause

NOT the script — scheduler.py line 482 drops the script path when building the bash command.

Workaround (temporary)

Direct bash execution bypasses scheduler: bash ~/.hermes/scripts/check_recent_chat.sh

Fix Applied

Patch scheduler.py line 482: cmd = [binary] → cmd = [binary, str(path)]

⚠️ TIMEOUT RECURRING (2026-05-05 02:xx, 03:xx)

  • The fix was documented as applied, but scheduler.py file does not exist in ~/.hermes/
  • check_recent_chat.sh timed out again at 02:03 and 03:25 cron runs
  • Root cause likely: the scheduler.py with the fix was not persisted, or fix wasn’t actually applied
  • Current workaround: The Dream task is still running (it reached me), but the check_recent_chat.sh script timeout is blocking the normal flow
  • Next step: Need to find and properly fix scheduler.py on the machine where the Hermes cron scheduler runs

⚠️ TIMEOUT RECURRING (2026-05-05 02:xx, 03:xx)

  • The fix was documented as applied at 00:02, but scheduler.py does NOT exist in ~/.hermes/
  • Timeouts occurred again at 02:03 and 03:25
  • Root cause: The fix was never actually persisted — scheduler.py with the fix either doesn’t exist or is in a different location
  • Next step: Need to find where scheduler.py actually lives

How to Find scheduler.py

The skill documentation says scheduler.py is in ~/.hermes/scheduler.py but this file doesn’t exist. Possible reasons:

  1. Hermes is installed as a pip package — scheduler.py is inside the package, not in ~/.hermes/
  2. Multiple hermes installations exist
  3. The scheduler is a separate process, not part of the agent

Finding the scheduler process:

# Find scheduler.py anywhere on the filesystem
find / -name "scheduler.py" 2>/dev/null
 
# Or find the hermes-scheduler process
ps aux | grep -i sched
 
# Check if hermes is installed as a pip package
pip show hermes-agent 2>/dev/null
pip show hermes-core 2>/dev/null
 
# Check the actual hermes binary/script location
which hermes
ls -la $(which hermes)

NEW INSIGHT (2026-05-05 06h)

  • Script uses #!/usr/bin/env bash → correctly goes through line 482: cmd = [binary, str(path)] ✓
  • BUT timeout still occurred → bug may be at line 489 for direct shebang paths (e.g. #!/bin/bash)
  • Line 489: cmd = [resolved] — missing str(path) argument for direct shebang
  • However our script uses /usr/bin/env so this doesn’t apply directly
  • Next debug step: Add stdin=subprocess.DEVNULL to prevent bash waiting for stdin

  • Cron ran check_recent_chat.sh → timed out at 120s
  • Dream task at 06:02 ALSO timed out (120s Dream task limit)
  • Dream task got into recursive self-reading loop — see skill/llm-wiki-dream-bug.md

14th Timeout (2026-05-06 09:02)

  • Cron ran check_recent_chat.sh → timed out at 120s
  • Dream task completed via direct execution (not scheduler)

15th Timeout (2026-05-06 12:02)

  • Cron ran check_recent_chat.sh → timed out at 120s

FIX APPLIED (2026-05-06 21:09 session)

Root Cause (confirmed): subprocess.run() at scheduler.py line ~495 did NOT have stdin=subprocess.DEVNULL. When scheduler runs bash script.sh, bash waits for stdin input by default. The subprocess never closes stdin → hangs forever → timeout.

Fix Applied (line 501):

stdin=subprocess.DEVNULL,  # Fix: prevent bash from waiting for stdin in cron context

⚠️ PENDING: Daemon restart required — running hermes gateway daemon (pre-fix) still runs old code. Restart with:

pkill -f "hermes gateway"
hermes gateway &

⚠️ PENDING: Git commit — fix not committed to git yet.
