# Todo 23 Agent Prompt and EventAgent LLM Plan

**Status:** done

## Goal

Move prompt configuration into Agent configuration and make EventAgent use a real LLM tool-call step to generate tool parameters.

## Why

Prompt Config is a separate modal while ChatAgent already owns the prompt that shapes visible replies. This splits one concept across two places. EventAgent also still resolves mock parameters locally; the target design requires EventAgent to use conversation context plus the selected event tool schema to ask the LLM for real arguments before executing tools.

## Scope

- Remove the standalone Prompt Config button and modal.
- Move prompt set management, system prompts, and pre-messages into the ChatAgent config modal.
- Show the generated available-event protocol prompt in ChatAgent prompt by default.
- Keep ChatAgent free of provider tools.
- Restore provider `tool_calls` parsing for EventAgent LLM parameter generation only.
- Make EventAgent call the LLM with only the corresponding event tool schema, then execute the returned arguments through the registry.
- Run multiple EventAgent events concurrently.

## Implementation

- Removed the standalone Prompt Config modal and moved prompt-set, system prompt, and pre-message controls into ChatAgent config.
- Added a generated available-event protocol prompt from the selected tools and populated it into ChatAgent system prompt by default.
- Kept ChatAgent provider calls tool-free while preserving text event extraction from `delta.content`.
- Restored provider `tool_calls` parsing for EventAgent LLM requests.
- EventAgent now calls the LLM with exactly the selected event tool schema, then executes the returned arguments.
- EventAgent handles multiple events concurrently with `asyncio.gather`.

## Verification

- Parser test proves provider `tool_calls` still become internal events for EventAgent.
- EventAgent tests prove it calls the LLM with the target tool schema, passes history/config, and executes generated arguments.
- Static UI tests prove Prompt Config is gone and prompt controls live in ChatAgent config.
- Runtime tests continue to prove ChatAgent receives no tools or `tool` role history.
- `uv run pytest` passes (`51 passed`, one existing Starlette deprecation warning).
- `UV_CACHE_DIR=.uv-cache uv run python -m py_compile ...` passes for the changed Python modules.
- Local server started and returned the page, static assets, and `/api/tools`; browser automation timed out during click verification, so modal click behavior is covered by static binding tests rather than a completed browser click run.
