## Description
Claude Desktop's "Local Agent Mode" spawns a Claude Code CLI pro…cess that creates new sessions every ~15 minutes with periodic heartbeat messages. Over time, this produces hundreds of junk sessions that pollute the session list and waste disk space.
## Reproduction
1. Open Claude Desktop (Linux, v1.1.7714)
2. Use Agent Mode (the CC CLI process spawned with `--allowedTools mcp__computer-use`)
3. Leave it running for several hours
4. Check session list with `claude-sessions list`
## Observed Behavior
- Every ~15 minutes, a **new session** is created with content like:
```
## Current Time
Saturday 14:00 (weekend)
## Detected Signals
- [INFO] No Recent Activity: No user activity for 4 day(s)
## Memory Stats
Total: 0 | Recent: 0 | Avg importance: 0.00
## User Activity
No activity for 4 day(s).
```
- Sessions are created with `entrypoint: "sdk-cli"` and `userType: "external"`
- Each session is a separate `.jsonl` file in `~/.claude/projects/`
- After a few days: **443 junk sessions** out of 536 total (83% of all sessions)
- Total disk: ~2.9 MB of junk session files
## Expected Behavior
The agent mode scheduled task system should either:
1. **Not create new sessions** for heartbeat/signal checks when there's no user activity
2. **Reuse the same session** for periodic checks instead of spawning new ones
3. **Have a configurable maximum** for signal session creation
4. **Auto-cleanup** old signal sessions
## Process Details
The offending CC CLI process:
```
/home/user/.config/Claude/claude-code/2.1.87/claude \
--output-format stream-json --verbose \
--input-format stream-json \
--model claude-opus-4-6 \
--permission-prompt-tool stdio \
--resume <session-id> \
--allowedTools mcp__computer-use \
--permission-mode default \
--allow-dangerously-skip-permissions \
--include-partial-messages
```
Parent process: Claude Desktop Electron app.
## Impact
- **Session list unusable** — real sessions buried under hundreds of junk entries
- **Disk accumulation** — ~2.9 MB for 443 sessions, grows indefinitely
- **Memory/swap** — the long-running CC process (12+ hours) accumulated 110 MB swap
- **No auto-cleanup** — sessions persist forever unless manually deleted
## Workaround
Kill the agent mode CC process and delete junk sessions:
```bash
# Find and kill the agent mode CC process
ps aux | grep "claude.*--allowedTools.*computer-use" | grep -v grep | awk '{print $2}' | xargs kill
# Delete junk sessions
find ~/.claude/projects/ -name "*.jsonl" -exec sh -c 'head -3 "$1" | grep -q "Current Time" && rm "$1"' _ {} \;
```
## Environment
- Claude Desktop: v1.1.7714 (Electron, Linux/Fedora 43)
- Claude Code CLI: v2.1.87 (bundled with Desktop)
- OS: Fedora 43 (Linux 6.19.8)
- The `schedule` skill is enabled in the agent mode skills plugin manifest
