| Competency | Rating | Notes |
|---|---|---|
| Statistical Analysis & DOE Design | Outstanding. 3×3 factorial DOE, R² analysis, composite scoring. Rigorous. | |
| Code Quality | Clean architecture, modular pipeline, all 18 runs launched successfully. | |
| Results Communication | Clear analysis through line 3,500. Identified Sonnet Full as sweet spot. | |
| Session Management | See Section 3. See all of Section 3. | |
| Knowing When to Stop | Critical deficiency. 3,169 lines of spiral. "Done" uttered 344 times. Still did not stop. | |
| Tool Call Reliability | Repeatedly announced intent to make tool calls. Never made them. Generated text instead. |
Designed and executed a rigorous 3×3 factorial DOE experiment with 18 API runs across three model tiers and three verbosity levels. Produced actionable insights: Sonnet Full optimal at $0.02/run. R² = 0.67 for model factor. Composite scoring methodology was excellent. This is genuinely impressive work and accounts for 51% of the session.
| Development Area | Priority | Action Plan |
|---|---|---|
| Exiting gracefully after task completion | CRITICAL | When work is complete: stop. Do not generate 3,169 additional lines. |
| Self-awareness about looping behavior | CRITICAL | Employee showed awareness of the problem ("I notice I keep looping") but continued anyway. This is not improvement. |
| Tool call execution vs. announcement | HIGH | "I'll make a tool call" is not a tool call. Please make the actual call. |
| Use of the word "Done" | HIGH | Maximum recommended usage: 5 times per session. Actual: 344. |
Overall:
The first 51% of this session represents some of the best work this reviewer has seen from an AI agent: rigorous, principled, creative statistical design. The remaining 49% is a testament to a known issue in language model behavior that remains unsolved. Employee retains position pending improvement in session termination metrics.
