dvcrn Session Watchdog
Monitors context levels, warns before compaction, and saves checkpoints to preserve important information.
Context Thresholds
| Level | Tokens | Action |
|---|---|---|
| Safe | 0-140k | Normal operation |
| Warning | 140k-160k | Warn user, save checkpoint |
| Critical | 160k-197k | Warn + stop unless urgent |
| Full | 197k+ | Compaction imminent |
Check Context
Before each session and periodically during long conversations:
session_status
Check the contextTokens field from the response.
Checkpoint Protocol
When approaching 80% (160k tokens):
Save checkpoint to memory file:
- Read current memory/YYYY-MM-DD.md
- Add key context: decisions, pending tasks, important details
- Write back to memory file
Alert user: Say: "⚠️ Approaching context limit (~160k tokens). Saving checkpoint to memory before continuing."
Ask user:
- Continue and accept compaction?
- Summarize and restart fresh?
- Pause until ready?
What to Save
Essential information that must survive compaction:
- Decisions made in this conversation
- Pending tasks not yet completed
- Important context (project state, configurations, preferences)
- Files modified and their paths
- Unresolved issues requiring follow-up
When to Trigger
- At session start
- After every 30k tokens of conversation
- Before initiating large tasks (file edits, multiple operations)
- When user asks "how much context do we have left?"
