tunnel-history - SKILL.md Agent Skill

name: tunnel-history description: Show aggregated history of a domain — thinking stages, importance breakdown, cognitive patterns, emotional tones, top concepts as bar charts. Use when user wants the meta-view of their own engagement with a topic over time. layer: utility reads: [L2.summaries, L0.all_conversations] writes: [] citations: output-is-citation determinism: pure-function allowed-tools: mcpmy-braintunnel_history

tunnel-history — utility meta-view

Framework context

Utility skill adjacent to tunnel-state: where tunnel-state is the current save-state, tunnel-history is the aggregate engagement profile across all time. Bar charts for distributions, not citations-per-row — the output IS the distribution.

When to invoke

User wants a retrospective: "overall, how have I been with X"
Before thinking-trajectory to establish baseline distribution
Coaching / self-reflection context

Input

domain: str

Output contract

## 📊 Tunnel History: {domain}
**Total conversations**: N
**Importance**: 💎 X · ⭐ Y · · Z

### Thinking stages (bar chart)
🚀 executing      ████████████  60%
🔧 refining       ████          20%
💎 crystallizing  ██            10%
🔍 exploring      ██            10%

### Cognitive patterns (top 7)
- deep-dive: 45
- architectural: 32
...

### Problem-solving approaches (top 7)
### Emotional tones (top 5)
### Top concepts (top 10 by frequency)

Does NOT do

Cite individual conversations (this is aggregate)
Show evolution over time (that's thinking-trajectory)
Compare domains (tunnel-history is single-domain)

Verification checklist

Bar chart uses █ character with 5% per char
Percentages sum to 100 (±1 for rounding)
Top-N slices are deterministic sort (count DESC, name ASC tiebreak)
