1.12.1

RubyLLM 1.12.1: Agent API Delegation + Rails add_message Persistence + Dependency Compatibility 🎉🤖🛠️

This is a focused patch release.

RubyLLM 1.12.1 tightens Agent behavior, fixes Rails chat persistence in add_message, and relaxes dependency constraints for better compatibility.

🤖 Agent API: Full Chat Delegation via Forwardable

Agents now delegate the full RubyLLM::Chat instance API to the wrapped chat object using Ruby’s Forwardable.

This also fixes the undefined method 'delegate' for class RubyLLM::Agent issue for PORO.

Delegated methods now include core accessors and fluent config methods like:

• model, messages, tools, params, headers, schema
• ask, say, complete, add_message, reset_messages!
• with_model, with_tools, with_params, with_headers, with_schema, etc.

agent = WorkAssistant.new
agent.with_model("gpt-5-nano")
agent.add_message(role: :user, content: "Summarize this thread")
response = agent.complete

Rails: Chat#add_message Now Persists Properly

Rails-backed chats now persist messages correctly when using add_message (not just ask/legacy flows).

chat = Chat.find(params[:chat_id])
chat.add_message(role: :user, content: params[:content]) # now persisted

Also included in this fix:

• tool-call linkage persistence for added messages
• attachment/content persistence handling improvements
• create_user_message remains as a compatibility wrapper (legacy/deprecated path)

📎 Attachment Robustness for Rails Multipart Inputs

RubyLLM::Content now ignores blank/nil attachment placeholder entries (common in Rails multipart arrays), preventing noisy failures when attachments include empty values.

📦 Dependency Compatibility Update

Dependency constraints were updated to reduce unnecessary pinning friction:

• ruby_llm-schema: ~> 0.2.1 → ~> 0
