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

1. Read current context usage from runtime status.
2. Run scripts/context_guard.py <used_tokens> <max_tokens>.
3. If threshold reached, output the new-session trigger and handoff hint.
4. 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:

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