# 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
