AgentDisruptBench — Disruption Profiles
========================================
File: profiles.py
Purpose: Built-in disruption profiles (9 profiles) and a YAML loader for
custom profiles. Profiles map a name to an ordered list of
DisruptionConfig entries that the engine evaluates per tool call.
Author: AgentDisruptBench Contributors
License: MIT
Created: 2026-03-09
Modified: 2026-03-09
Key Definitions:
BUILTIN_PROFILES : dict[str, list[DisruptionConfig]] All 9 built-in
profiles defined in the AgentDisruptBench spec.
load_profiles : Load profiles from a YAML file on disk.
get_profile : Retrieve a profile by name (built-in or custom).
Convention:
Every source file MUST include a header block like this one.
