# Session Analysis Patterns

## Session Metrics

| Metrik | İyi | Orta | Kötü |
|--------|-----|------|------|
| Tokens per task | <50K | 50-100K | >100K |
| Tool calls per task | <20 | 20-40 | >40 |
| Repeated reads | 0-1 | 2-3 | >3 |
| Blind edits | 0 | 1 | >1 |
| Agent spawn efficiency | >80% useful | 50-80% | <50% |

## Anti-Pattern Catalog

| # | Pattern | Tespit | Fix |
|---|---------|--------|-----|
| 1 | **Repeated Read** | Aynı dosya 3+ kez okunmuş | Bilgiyi ilk seferde kaydet |
| 2 | **Wide Grep** | Pattern'siz geniş arama | Spesifik pattern + glob filter |
| 3 | **Blind Edit** | Dosya okumadan edit | Read → Edit sırası zorunlu |
| 4 | **Idle Agent** | Agent spawn edilip sonuç kullanılmamış | Gereksiz spawn etme |
| 5 | **Cascade Fail** | Aynı hata 3+ kez retry | Root cause analiz et |
| 6 | **Context Pollution** | Ana context'te gereksiz büyük dosya okuma | Agent'a delege et |
| 7 | **Premature Agent** | Basit iş için agent spawn | Direkt tool kullan |
| 8 | **Missing Parallel** | Bağımsız işler sıralı | Paralel agent/tool call |
| 9 | **Over-Engineering** | Basit fix için büyük refactoring | Minimal değişiklik |

## Efficiency Scorer (0-100)

```python
def calculate_efficiency(session):
    score = 100

    # Penalties
    score -= session.repeated_reads * 5       # -5 per repeated read
    score -= session.blind_edits * 15         # -15 per blind edit
    score -= session.wide_greps * 3           # -3 per wide grep
    score -= session.idle_agents * 10         # -10 per idle agent
    score -= session.cascade_fails * 8        # -8 per cascade fail

    # Bonuses
    score += session.parallel_calls * 2       # +2 per parallel batch
    score += session.first_pass_success * 5   # +5 per first-try success

    return max(0, min(100, score))
```

## Session Comparison

```markdown
| Metrik | Session A | Session B | Delta |
|--------|-----------|-----------|-------|
| Total tokens | 45,000 | 120,000 | +167% |
| Tool calls | 12 | 38 | +217% |
| Time (min) | 3 | 12 | +300% |
| Tasks completed | 2 | 2 | 0% |
| Efficiency score | 88 | 42 | -52% |
```

## Braintrust Log Analysis

```bash
# Session analizi
btca sessions list --last 7d
btca session <id> --metrics

# Pattern detection
btca session <id> --anti-patterns

# Cost analysis
btca sessions list --sort cost --desc
```

## Checklist

- [ ] Session token usage tracked
- [ ] Anti-pattern detection aktif
- [ ] Efficiency score > 70
- [ ] Repeated reads < 2
- [ ] Blind edits = 0
- [ ] Parallel opportunities exploited
- [ ] Agent spawn ROI positive

## Anti-Patterns

- Her session'ı analiz etmek (sadece outlier'ları analiz et)
- Metric'lere takılıp task quality'yi ihmal etmek
- Hız için correctness'tan ödün vermek

Hyperplan

Adversarial multi-agent planning skill. Self-orchestrates 5 hostile category members (unspecified-low, unspecified-high, deep, ultrabrain, artistry) via team-mode for ruthless cross-critique debate, distills only the defensible insights, then MANDATORILY hands the distilled insight bundle to the `plan` agent for executable plan formalization. Use when planning needs maximum rigor and surfacing of weak assumptions, blind spots, and over-engineering. Triggers: 'hyperplan', 'hpp', '/hyperplan', ...

catchup

Recovers the conversation and failed tool calls of a previous Codex, Amp, Claude Code, Antigravity, Cline, Copilot CLI, Cursor, DeepSeek Harness, Grok Build, Kimi, OpenCode, Pi Agent, or ZCode session. Use when the user says "catch up", "what did the last session do", "get me up to speed", "I switched agents", asks to recover/summarize a previous session before continuing, or asks to diagnose or report a catchup failure. Do NOT use for the current conversation, git history, or any non-agent log.
