Context Visualization
Estimate and display a breakdown of the current context window usage.
How It Works
Run the bundled script to estimate token counts for workspace files:
python3 scripts/estimate_tokens.py /path/to/workspace
The script counts characters in known workspace files and estimates tokens (~4 chars/token).
Then call session_status to get the actual context usage from OpenClaw.
Generating the Visualization
- Run
session_statusto get: model, context used/total, compactions - Run
scripts/estimate_tokens.py \x3Cworkspace_path>to estimate file token sizes - Estimate message tokens:
context_used - system_overhead - file_tokens - Present the breakdown using the format below
Output Format
Use a monospace block with bar chart. Adapt the bar lengths proportionally.

Use ░ blocks: 1 block per ~2% of total context. Round to nearest block.
Memory Inventory (not in context)
Below the context chart, add a Memory on Disk section showing what's stored in memory/ — grouped by category. These files are NOT loaded into context but represent the agent's total knowledge base.

The script auto-categorizes files by directory or filename pattern.
Notes
- Token estimates use ~4 chars/token (rough average for English/mixed content)
- System prompt + tools overhead is estimated at ~8-10k tokens for a typical OpenClaw setup
- Message tokens are the remainder after subtracting files + system overhead
- Memory files are informational only — they show what the agent has accumulated
- For Discord/WhatsApp: skip markdown tables, use the block format above
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install context-viz - After installation, invoke the skill by name or use
/context-viz - Provide required inputs per the skill's parameter spec and get structured output
