lib/brainiac/version.rb

Overview

Brainiac hook system.

Provides a lightweight pub/sub mechanism for plugins to extend core behavior without core knowing about specific plugins.

Core emits events at lifecycle points. Plugins register handlers via Brainiac.on.

Events:

:agent_completed    — After an agent session finishes (success or failure)
:pr_merged          — After a GitHub PR is merged
:pr_opened          — After a GitHub PR is opened
:pr_reviewed        — After a PR review is submitted
:build_brain_context — When building brain context (plugins add source-specific queries)
:pre_dispatch       — Before dispatching an agent (plugins can inject config)
:post_comment       — After an agent posts a comment/response

Usage (in plugin .register):

Brainiac.on(:agent_completed) do |ctx|
move_card_to_column(ctx[:card_number], "needs_review", ...)
end

Usage (in core):

Brainiac.emit(:agent_completed, card_number: 42, agent_name: "Sherlock", ...)
