Modules

bridge

Bridge connecting the legacy hooks API to the middleware pipeline.

builtins

Built-in middleware implementations

hook

HookMiddleware — bridges the HookRunner port into the pipeline so Pre/PostToolUse fire alongside audit/authorizer. HookMiddleware — bridge HookRunner into the existing MiddlewarePipeline so Pre/PostToolUse hooks fire through the same path as audit/authorizer middlewares.

observability_adapters

Adapters that bridge SDK observability/security types (AuditLog, Authorizer) into the Middleware pipeline so they compose with user middlewares instead of overwriting the AgentHooks struct. See module docs for design rationale. Observability adapters — bridges for SDK observability types into the Middleware pipeline so they cooperate with user-added middleware instead of overwriting it.

plugin

Plugin loader for dynamic middleware loading

Structs

MiddlewareContext

Context passed to middleware during execution.

MiddlewarePipeline

Ordered chain of middlewares executed phase by phase.

MiddlewareResult

Result of middleware execution.

Enums

MiddlewareAction

Middleware action — determines how the pipeline continues.

MiddlewareData

Middleware data — context passed to middlewares per phase.

MiddlewarePhase

Middleware execution phase.

Traits

Middleware

Middleware trait — implement this to add behavior to the agent pipeline.
