ReCentAutomaยถ
ReCentAutoma is an agentic module implementation in Bridgic that provides a goal-oriented, guidance-enabled long-running autonomous agent. It enables developers to build intelligent systems that can autonomously plan and execute multi-step tasks using tools, with built-in memory management and goal tracking.
Introductionยถ
ReCentAutoma serves as a specialized agentic module in Bridgic, designed to provide a goal-oriented, guidance-enabled implementation for long-running autonomous agents. It addresses the fundamental challenges of building intelligent systems that can autonomously plan, execute, and adapt over extended interactions.
When to Use ReCentAutomaยถ
ReCentAutoma is suitable when you need to develop an application with autonomous capabilities and dynamic tool usage. In many cases, developers also need:
- Efficient memory management: As tasks span multiple steps and tool calls, conversation history grows. ReCentAutoma's built-in ReCENT memory managemnt algorithm automatically compresses history when needed, preventing context explosion.
- Natural language goal definition: ReCentAutoma accepts
goalas a first-class input, so you can state your objectives directly in natural language. - Customized task guidance: You can provide an optional
guidanceinput to further constrain or direct the agent's behavior, enabling more control across the execution.
These capabilities are well-supported in ReCentAutoma, making it ideal for building autonomous agents that need to:
- Dynamically make decisions at runtime to select tools for each step
- Autonomously execute multiple steps during a long-time task
- Automatically maintain alignment with the initial goal throughout the entire execution process
How Does ReCentAutoma Workยถ
ReCentAutoma leverages GraphAutoma's core featuresโdynamic topology and dynamic routingโto implement an enhanced ReAct (Resoning and Acting) loop. It incorporates the innovative ReCENT (Recursive Compressed Episodic Node Tree) memory management algorithm, which triggers memory compression when necessary, effectively addressing two long-standing challenges in autonomous agents:
- Context Explosion: As conversation history grows linearly, the context window eventually overflows. ReCENT automatically compresses episodic memory when thresholds are reached, maintaining a compact yet informative context.
- Goal Drift: Without explicit goal management, agents tend to deviate from original objectives during extended execution. ReCentAutoma maintains goal and guidance as persistent, non-compressible nodes, ensuring the agent stays focused on the original task.
Quick Startยถ
Let's explore ReCentAutoma through practical examples. We'll start with a simple weight management assistant using custom tools, then move to a more advanced browser automation agent using MCP integration.
First of all we have to initialize an LLM instance:

import os
from bridgic.llms.openai import OpenAILlm, OpenAIConfiguration
dotenv.load_dotenv()
_api_key = os.environ.get("OPENAI_API_KEY")
_api_base = os.environ.get("OPENAI_API_BASE", "https://api.openai.com/v1")
_model_name = os.environ.get("OPENAI_MODEL_NAME", "gpt-4o-mini")
# Initialize LLM (you can replace this with your own LLM instance)
llm = OpenAILlm(
api_base=_api_base,
api_key=_api_key,
configuration=OpenAIConfiguration(model=_model_name),
timeout=60,
)

Example 1: Building a Weight Management Assistant with Custom Toolsยถ
In this example, we'll create custom tools for BMI calculation and ideal weight calculation, then use ReCentAutoma to build a weight management assistant that can help users understand their health metrics.

Example 2: Building a Browser Automation Agent with Playwright MCP Serverยถ
This example demonstrates how to integrate ReCentAutoma with MCP (Model Context Protocol) to create a browser automation agent. We'll use the Playwright MCP server to enable the agent to interact with browsers like Chrome autonomously to achieve the user-defined goal.
This example demonstrates how to combine ReCentAutoma with MCP (Model Context Protocol) Integration to build a browser automation agent for retrieving the latest gold prices from the official website of the Hong Kong Gold Exchange.
Steps overview:
- Connect to the Playwright MCP server via stdio transport for browser automation capabilities.
- Register the connection using a dedicated Connection Manager to manage browser operations in isolation.
- Create a
ReCentAutomaagent loaded with browser automation tools. - Let the agent autonomously navigate to the Hong Kong Gold Exchange website and extract the needed information.
If youโre new to MCP, please check the MCP Quick Start for setup and usage instructions.

Final Result: Based on the information gathered from the Hong Kong Gold Exchange (HKGX) website (https://hkgx.com.hk/en), here is a summary of the recent gold price trends for RMB-denominated kilo gold: 1. Navigational Steps: - Accessed the HKGX homepage. - Hovered over the 'Market & Data' menu to reveal additional options. - Selected and clicked on the 'Price History' option to open the historical prices page. - Chose the "RMB Kilo Gold" product option for the current date range. - Clicked the search button to retrieve recent historical price data. 2. Recent Gold Price Data for RMB-denominated Kilo Gold (Selected Dates in January 2026): | Date | Open | High | Low | Close | Benchmark Price | |------------|----------|----------|----------|----------|-----------------| | 2026-01-26 | 1121.43 | 1142.14 | 1120.03 | - | 1134.15 | | 2026-01-23 | - | 0.00 | 0.00 | - | - | | 2026-01-22 | 1077.35 | 1105.64 | 1068.54 | 1105.24 | 1073.00 | | 2026-01-21 | 1065.21 | 1093.60 | 1063.93 | 1080.88 | 1084.50 | 3. Observations and Trends: - The benchmark price on January 26, 2026, was 1134.15 RMB per kilo, reflecting an increase compared to previous dates. - From January 21 to January 26, prices opened around 1065 to 1121 RMB and showed upward movement with highs reaching above 1142 RMB. - Some missing or zero values around January 23 possibly indicate non-trading days or unavailable data. - Overall, there is a general upward trend in the benchmark prices and daily highs over the few recorded days in late January 2026. In conclusion, the RMB-denominated kilo gold prices on the Hong Kong Gold Exchange have shown an upward trend in the past few days of January 2026, with the latest benchmark price around 1134.15 RMB per kilo as of January 26, 2026. This reflects strengthening price momentum within this timeframe. If you need gold price data for other denominations, dates, or require ongoing updates, you can use the HKGX Price History page to explore as needed. โ Connection closed: True
In this example, the agent autonomously uses a browser to navigate to the Hong Kong Gold Exchange website and search for the gold price. The entire execution process is fully recorded during the execution of ReCentAutoma (as shown above).
Because we launched the Playwright MCP Server with the --save-video option, a recording of the session is saved after execution. The entire browser operation can be viewed in the following video:
Build a Multi-Agent System with ReCentAutomaยถ
Bridgicโs component-based architecture makes it a natural choice for building Multi-Agent systems.
Because ReCentAutoma itself is an Automa (and also a Worker), it can be flexibly nested and combined with other automas. This allows you to create hierarchical agentic systems, where each agent manages its own goals, tools, and memory independently. There are two common methods for building a Multi-Agent system:
- Utilizing a
ReCentAutomainstance as a nested worker, allowing for flexible and customized dynamic routing - Integrating
ReCentAutomaas a kind of tool, enabling intelligent and context-aware parameter filling
