Auto-create a new session when OpenClaw context usage reaches 80% without requiring Mem0 or file memory systems. Use when users want default OpenClaw to proactively rotate sessions and avoid context overflow in long chats.

Session Rotate 80

Overview

Trigger a standard

[NEW_SESSION]

message when context usage reaches 80%. This skill is memory-system-agnostic and works in plain default OpenClaw setups.

Workflow

Read current context usage from runtime status.

Run

scripts/context_guard.py <used_tokens> <max_tokens>

If threshold reached, output the new-session trigger and handoff hint.
Keep old session only for short handoff, then continue in new session.

Command

python scripts/context_guard.py <used_tokens> <max_tokens> --threshold 0.8 --channel boss

Example:

python scripts/context_guard.py 220000 272000 --threshold 0.8 --channel boss

Expected Output

At or above threshold:

```
[ROTATE_NEEDED]
```

[NEW_SESSION] 上下文达到80%（used/max），自动切换新会话

```
[HANDOFF_HINT] ...
```

Below threshold:

```
[ROTATE_NOT_NEEDED] ratio=x.xx < 0.800
```

Integration Hint (Heartbeat)

In heartbeat flow, after reading context usage:

Call
```
context_guard.py
```
.
If
```
[ROTATE_NEEDED]
```
, emit
```
[NEW_SESSION]...
```
directly.
Stop handling new tasks in old session except handoff confirmation.

```
scripts/context_guard.py
```
: threshold detector and trigger emitter (no memory dependency).
