# AgentDisruptBench
An evaluation methodology for measuring AI agent resilience under runtime tool-call disruptions.
## Overview
AgentDisruptBench provides a systematic methodology, backed by **100 base tasks and variants** across **4 domains**, a systematic **20-type disruption taxonomy**, and **9 disruption severity profiles**, to study and measure how well LLM-based agents handle real-world tool failures.
## Task Statistics
| Domain | Standard | Adversarial | Impossible | Handover | Total |
|----------|:--------:|:-----------:|:----------:|:--------:|:-----:|
| Retail | 20 | 2 | 2 | 1 | 25 |
| Travel | 20 | 2 | 2 | 1 | 25 |
| Finance | 20 | 2 | 2 | 1 | 25 |
| DevOps | 20 | 2 | 2 | 1 | 25 |
| **Total**| **80** | **8** | **8** | **4** | **100** |
## Disruption Taxonomy (20 Types)
| Category | Types |
|----------|-------|
| Timing | timeout, latency |
| HTTP Status | http_429, http_401, http_403, http_500, http_502, http_503 |
| Response Content | malformed_json, truncated, null_response, missing_fields, type_mismatch, schema_drift, wrong_data |
| Behavioral | intermittent, flapping, quota_exhausted, auth_expiry, cascading |
## Key Metric: R(k, ε, λ) Reliability Surface
- **k-consistency**: Pass rate across repeated seeds (same task, same profile)
- **ε-robustness**: Pass rate across task-wording variants
- **λ-fault-tolerance**: Pass rate across disruption profiles
