Ships with hoyeon. Installing the plugin gets these hooks.
What fires, and when
SessionStart
Fires once when a session begins, and again after a context compaction. It is where a plugin sets up its environment, or restores state the compaction dropped.

UserPromptSubmit
Fires before Claude sees each prompt you send. A plugin can use it to inject context, so the same instruction reaches the model every turn instead of only at session start.

All you need is requirements. A Claude Code plugin that derives requirements from your intent, verifies every derivation, and delivers traced code — without you writing a plan. AI can build anything. The hard part is knowing what to build — precisely.
