context-viz

name	context-viz
description	Visualize the current context window usage — token estimates per component (system prompt, tools, workspace files, messages, free space). Use when the user asks about context size, token usage, context breakdown, "how full is the context", or wants to see what's consuming their context window.

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

1. Run session_status to get: model, context used/total, compactions
2. Run scripts/estimate_tokens.py <workspace_path> to estimate file token sizes
3. Estimate message tokens: context_used - system_overhead - file_tokens
4. Present the breakdown using the format below

Output Format

Use a monospace block with bar chart. Adapt the bar lengths proportionally.

📊 Context Usage
<model> • <used>k/<total>k tokens (<pct>%)

Use ░ blocks: 1 block per ~2% of total context. Round to nearest block.
