Overview

A named block of system-prompt text, composable like a Toolset.

Prompts are code, not data: git is the version store. Bodies may be a String or a block; a block stays lazy so a host reading from disk picks up edits on to_prepare reload without a boot.

Instance Method Details

#body(text = nil, &block) ⇒ Object

Setter with text or a block; reader (no args) returns this prompt's own resolved body only. Use #full_body for the composed result.

def body(text = nil, &block)
  return own_body if text.nil? && block.nil?
  @body = block || text
end

#full_body ⇒ Object

Composed bodies first, then this prompt's own — so shared framing (safety rules, draft status) precedes the specialisation that builds on it.

def full_body
  collect_bodies.compact_blank.join("\n\n").presence
end

#use(*keys) ⇒ Object

Compose other prompts into this one. Keys resolve lazily (at full_body time), so definition load order does not matter.

def use(*keys)
  @composed_keys.concat(keys.map(&:to_s))
