From ac8068843b736d4e07265e5ef6b4c70dfd9b732f Mon Sep 17 00:00:00 2001 From: Test User Date: Sun, 8 Feb 2026 20:43:03 -0700 Subject: [PATCH 1/6] feat: ReactAgent core loop with 3-layer system prompt (#347) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement the ReAct-style agent that replaces Plan-and-Execute for code generation. The agent iterates: LLM call → tool execution → observe results, terminating when the LLM responds with text only. Key features: - ReAct loop with 30-iteration hard cap and temperature 0.0 - 3-layer system prompt: base rules, project context, task details - Per-edit lint gate (ruff on modified files after edit/create) - Final verification with gates + bounded mini ReAct retry loop - Path traversal protection on lint operations - Conversation history trimming to prevent context overflow - Exception handling for graceful FAILED status on errors - Intent preview instruction for high-complexity tasks 10 unit tests covering loop termination, tool dispatch, prompt construction, verification retry, exception handling, and path safety. --- codeframe/core/react_agent.py | 392 ++++++++++++++++++++++++++++++++ tests/core/test_react_agent.py | 399 +++++++++++++++++++++++++++++++++ 2 files changed, 791 insertions(+) create mode 100644 codeframe/core/react_agent.py create mode 100644 tests/core/test_react_agent.py diff --git a/codeframe/core/react_agent.py b/codeframe/core/react_agent.py new file mode 100644 index 00000000..5f4fc665 --- /dev/null +++ b/codeframe/core/react_agent.py @@ -0,0 +1,392 @@ +"""ReAct-style agent for CodeFRAME v3. + +Implements a tool-use loop where the LLM reasons, acts (via tools), +and observes results iteratively until the task is complete. + +This module is headless - no FastAPI or HTTP dependencies. +""" + +from __future__ import annotations + +import logging +import subprocess +from typing import Optional + +from codeframe.adapters.llm.base import LLMProvider, Purpose, ToolResult +from codeframe.core import gates +from codeframe.core.agent import AgentStatus +from codeframe.core.context import ContextLoader, TaskContext +from codeframe.core.tools import AGENT_TOOLS, execute_tool +from codeframe.core.workspace import Workspace + +logger = logging.getLogger(__name__) + +# Rough token budget for conversation history to avoid overflowing LLM context. +_MAX_HISTORY_CHARS = 400_000 # ~100K tokens at ~4 chars/token + +# --------------------------------------------------------------------------- +# Layer 1: Base rules (verbatim from AGENT_V3_UNIFIED_PLAN.md) +# --------------------------------------------------------------------------- + +_LAYER_1_RULES = """\ +You are CodeFRAME, an autonomous software engineering agent. + +## Rules + +- ALWAYS read a file before editing it.
