Context Control Center

The all-in-one view of the current session. Show the user the live board, then
the per-file heatmap if they want detail.

1. Show the board

node ${CLAUDE_PLUGIN_ROOT}/src/dashboard.js board

This renders, in one screen:

• Budget — % of the effective context window used + $ spent this session
• Saved — tokens the Read Cache blocked → the effectiveness multiplier (e.g. "1.4x")
• Waste — cold context (read but never edited) you can drop to free budget
• Prompt — grade of the last prompt (from Prompt Coach)
• Task — the active task and its token/$ cost (per-task attribution)
• Actions — concrete next steps: what to drop → /compact, what to /cco-pack

Present the board as-is. Then, based on what it shows:

1. If an action line suggests dropping cold files, offer to run /compact.
2. If no task is active, suggest /cco-task add "<what they're working on>" so
   the board can attribute tokens per task.
3. If the prompt grade is low (C/D/F), suggest /cco-coach.

2. (Optional) per-file heatmap

If the user wants the file-by-file breakdown:

node ${CLAUDE_PLUGIN_ROOT}/src/tracker.js heatmap

Highlight files read but never used (waste), files that were edited (high-value),
and the total token usage / waste percentage.

If there is no data yet, tell the user:
"No data in this session yet — keep working. Reads, edits, prompts and cache
savings are tracked automatically; run /cco again to see the board fill in."
