Halftrace – See the shape of your agent's failures from your logs

AI Analysis
●●●BangerBig BrainSolve My ProblemDark Horse
Diagnoses agent failure modes from existing logs without spending new API credits.
Strengths
- •Distinguishes between 'bimodal' and 'average' failure modes to suggest specific prompt fixes.
- •Compares two log sets to verify if prompt changes actually improved compliance.
- •Zero-cost analysis by parsing existing JSONL exports from OpenAI, Anthropic, or LangSmith.
Weaknesses
- •Limited to specific JSONL export formats; custom agent frameworks may need adapters.
- •Relies on heuristics for 'shape' classification which may miss nuanced context.
