Harrison Chase	b7708bbec6	rfc: callback changes (#1165 ) conceptually, no reason a tool should know what an "agent action" is unless any objections, can change in all callback handlers	1 year ago
Ankush Gola	7b5e160d28	Make Tools own model, add ToolKit Concept (#1095 ) Follow-up of @hinthornw's PR: - Migrate the Tool abstraction to a separate file (`BaseTool`). - `Tool` implementation of `BaseTool` takes in function and coroutine to more easily maintain backwards compatibility - Add a Toolkit abstraction that can own the generation of tools around a shared concept or state --------- Co-authored-by: William FH <13333726+hinthornw@users.noreply.github.com> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Francisco Ingham <fpingham@gmail.com> Co-authored-by: Dhruv Anand <105786647+dhruv-anand-aintech@users.noreply.github.com> Co-authored-by: cragwolfe <cragcw@gmail.com> Co-authored-by: Anton Troynikov <atroyn@users.noreply.github.com> Co-authored-by: Oliver Klingefjord <oliver@klingefjord.com> Co-authored-by: William Fu-Hinthorn <whinthorn@Williams-MBP-3.attlocal.net> Co-authored-by: Bruno Bornsztein <bruno.bornsztein@gmail.com>	1 year ago
Jason Liu	54f9e4287f	Pass kwargs from initialize_agent into agent classmethod (#799 ) # Problem I noticed that in order to change the prefix of the prompt in the `zero-shot-react-description` agent we had to dig around to subset strings deep into the agent's attributes. It requires the user to inspect a long chain of attributes and classes. `initialize_agent -> AgentExecutor -> Agent -> LLMChain -> Prompt from Agent.create_prompt` ``` python agent = initialize_agent( tools=tools, llm=fake_llm, agent="zero-shot-react-description" ) prompt_str = agent.agent.llm_chain.prompt.template new_prompt_str = change_prefix(prompt_str) agent.agent.llm_chain.prompt.template = new_prompt_str ``` # Implemented Solution `initialize_agent` accepts `*kwargs` but passes it to `AgentExecutor` but not `ZeroShotAgent`, by simply giving the kwargs to the agent class methods we can support changing the prefix and suffix for one agent while allowing future agents to take advantage of `initialize_agent`. ``` agent = initialize_agent( tools=tools, llm=fake_llm, agent="zero-shot-react-description", agent_kwargs={"prefix": prefix, "suffix": suffix} ) ``` To be fair, this was before finding docs around custom agents here: https://langchain.readthedocs.io/en/latest/modules/agents/examples/custom_agent.html?highlight=custom%20#custom-llmchain but i find that my use case just needed to change the prefix a little. # Changes Pass kwargs to Agent class method * Added a test to check suffix and prefix --------- Co-authored-by: Jason Liu <jason@jxnl.coA>	1 year ago
