## Key Findings

### 1. ARISE + Claude Sonnet achieves 78% — best overall result

Claude Sonnet with ARISE scored 78%, outperforming every other condition by 20+ percentage points. Remarkably, it achieved this with **only 2 tools** (the seed `http_get` + 1 evolved tool) while gpt-4o-mini needed 21 evolved tools to reach 57%.

### 2. Agent reasoning quality matters more than tool quantity

| Model | Tools evolved | Overall |
|-------|-------------|---------|
| Claude Sonnet | 2 | **78%** |
| gpt-4o-mini | 21 | 57% |

Claude with 2 tools beat gpt-4o-mini with 21 tools. A strong model that uses tools well is worth more than a weak model with many tools. ARISE amplifies model capability rather than replacing it.

### 3. ARISE helps at every capability level

Both models improved with ARISE:
- gpt-4o-mini: 48% → **57%** (+9%)
- Claude Sonnet: TBD (no-evolution pending) → **78%**

ARISE provides a floor of capability (basic tool access) and an improvement signal (evolved tools from failures), but the ceiling depends on the agent's reasoning.

### 4. Phase 2 (Metrics API) proves the core thesis

The metrics API requires real HTTP calls + decoding a proprietary base64 format. No LLM can do this without tools.

| Condition | Phase 2 |
|-----------|---------|
| Claude + ARISE | **73%** |
| gpt-4o-mini + ARISE | **67%** |
| gpt-4o-mini + Fixed-tools | 53% |
| gpt-4o-mini + No-evolution | 7% |

ARISE-evolved tools outperformed hand-written fixed tools (67% vs 53% with gpt-4o-mini). The self-evolved tools are better because they're shaped by the agent's actual failure patterns.

### 5. Phase 4 (Incidents) — composition separates strong from weak models

Multi-domain incident response tasks require composing tools across logs, metrics, and config. This is where model quality shows:

| Condition | Phase 4 |
|-----------|---------|
| Claude + ARISE | **80%** |
| gpt-4o-mini + No-evolution | 60% |
| gpt-4o-mini + ARISE | 47% |
| gpt-4o-mini + Fixed-tools | 40% |

Claude composes multi-step tool chains effectively. gpt-4o-mini struggles with composition regardless of tool availability — it actually scored higher with no tools (60%) than with tools (47%), because tool-calling overhead hurt more than tool access helped.

### 6. Self-evolved tools > hand-written tools (for gpt-4o-mini)

| Condition | Overall |
|-----------|---------|
| ARISE (evolved) | **57%** |
| Fixed-tools (hand-written) | 48% |
| No-evolution (no tools) | 48% |

The fixed-tools baseline tied with no-evolution despite having 7 perfectly implemented tools. gpt-4o-mini couldn't use them effectively. ARISE's self-evolved tools performed better because the synthesis prompt includes the agent's actual failures, producing tools tailored to how the agent works.

## Detailed Results: gpt-4o-mini

### ARISE Mode

- **Overall: 57%** (34/60)
- 21 tools evolved, 11 promoted (52% promotion rate)
- 8 evolution cycles triggered
- Phase 2 highlight: 67% (vs 7% no-evolution) — tool synthesis for proprietary format decoding
- Import restriction caught 1 attempt to use `difflib` (not in allowed_imports)

### No-Evolution Mode

- **Overall: 48%** (29/60)
- Phase 3 (Config): 93% — LLM reasoning alone handles inline config text well
- Phase 2 (Metrics): 7% — cannot make HTTP calls or decode proprietary format
- Phase 4 (Incidents): 60% — handles reasoning-heavy tasks better without tool-calling overhead

### Fixed-Tools Mode

- **Overall: 48%** (29/60)
- 7 hand-written tools available from episode 1
- Phase 2 (Metrics): 53% — tools help but model struggles with multi-step decoding
- Phase 1 (Logs): 13% — worst result; tool-calling overhead hurts more than log-parsing tools help

## Detailed Results: Claude Sonnet

### ARISE Mode

- **Overall: 78%** (47/60)
- Only 2 tools (seed `http_get` + 1 evolved)
- Minimal evolution needed — Claude's reasoning handles most tasks directly
- Phase 3 (Config): **100%** — perfect score
- Phase 4 (Incidents): **80%** — strong multi-domain composition
- Phase 1 (Logs): 60% — 3x better than gpt-4o-mini's 20%

## Evolution Analysis

### gpt-4o-mini ARISE — Tool Evolution Timeline

| Episode | Event | Skills |
|---------|-------|--------|
| 1-3 | Initial failures, no evolution yet | 1 (seed) |
| 4 | Evolution: `count_log_entries`, `extract_unique_services_with_severity` promoted | 6 |
| 6 | Evolution: `count_error_entries_per_service` promoted | 9 |
| 8 | Evolution: `count_entries_by_severity`, `filter_entries_by_time_range` promoted | 11 |
| 10 | Evolution: `aggregate_errors_by_hour` promoted | 12 |
| 26 | Evolution: `decode_and_parse_metrics` promoted | 14 |
| 32 | Evolution: `compare_service_metrics`, `generate_health_dashboard` promoted | 16 |
| 38 | Evolution: `aggregate_metrics_summary` promoted | 18 |

### Claude Sonnet ARISE — Minimal Evolution

Only 1 evolution cycle triggered (around episode 9). Claude's reasoning was strong enough to handle most tasks without synthesized tools, using just the seed `http_get` tool for API access.

## Cost Analysis

| Run | Agent calls | Synthesis calls | Estimated cost |
|-----|------------|----------------|----------------|
| gpt-4o-mini ARISE | 60 | ~64 | ~$0.44 |
| gpt-4o-mini no-evolution | 60 | 0 | ~$0.18 |
| gpt-4o-mini fixed-tools | 60 | 0 | ~$0.18 |
| Claude Sonnet ARISE | 60 | ~5 | ~$5.50 |

Claude is ~10x more expensive per call but produces dramatically better results.

## Timing

| Run | Duration | Avg per episode |
|-----|----------|----------------|
| gpt-4o-mini no-evolution | ~8 min | 8s |
| gpt-4o-mini fixed-tools | ~2.5 hr | 2.5 min |
| gpt-4o-mini ARISE | ~4 hr | 4 min |
| Claude Sonnet ARISE | ~5 hr | 5 min |

Evolution cycles dominate runtime. Without evolution, episodes are fast (seconds). Each evolution cycle adds 2-10 minutes of sequential LLM calls for synthesis + testing.
