Structured 16-chapter tutorial organized into 5 progressive parts (Foundations → Single Agents → Advanced Capabilities → Real-World Case Studies → Capstone) that teaches agent architecture from first principles through implementation. Each chapter includes executable Python code examples demonstrating concepts like ReAct paradigm, Plan-and-Solve patterns, and reflection mechanisms, with bilingual documentation (Chinese/English) supporting learners at different experience levels.
Unique: Explicitly teaches both 'using wheels' (existing frameworks) and 'building wheels' (custom HelloAgents framework implementation), with clear architectural distinction between AI-Native agents (LLM-centric) and Software Engineering agents (workflow-centric), supported by 16 progressive chapters with executable code examples rather than abstract theory alone
vs alternatives: More comprehensive and hands-on than academic papers on agent design, yet more technically rigorous than marketing-focused framework documentation, with explicit comparison of agent paradigms (ReAct vs Plan-and-Solve vs Reflection) to help practitioners choose appropriate patterns
Lightweight Python framework providing base agent classes, unified LLM client integration (supporting OpenAI, Anthropic, Ollama, and other providers), and a tool registry system for function calling. The framework abstracts provider-specific API differences through a common interface, enabling agents to switch LLM backends without code changes while managing message history, configuration, and extension patterns through inheritance and composition.
Unique: Intentionally minimal framework design that teaches agent architecture through readable source code rather than hiding complexity behind abstractions; explicit separation of LLM client integration, tool registry, and message management allows learners to understand each component's responsibility and modify them independently
vs alternatives: Simpler and more transparent than LangChain for learning agent fundamentals, but less feature-complete for production use; designed for educational clarity rather than enterprise robustness
Framework for training agents through reinforcement learning feedback, where agent outputs are evaluated against success criteria and used to optimize behavior. The pipeline includes reward signal generation, trajectory collection from agent runs, and training loops that improve agent decision-making based on outcomes, enabling agents to learn from experience rather than relying solely on pre-trained LLM weights.
Unique: Provides concrete patterns for implementing RL training loops for agents, including reward signal generation and trajectory collection, treating RL as an optional optimization layer rather than a requirement, enabling teams to start with prompt-based agents and add RL training as they scale
vs alternatives: More sophisticated than pure prompt engineering but more practical than full policy learning from scratch; enables continuous improvement of agent behavior based on real-world performance
Systematic approach to measuring agent performance across multiple dimensions (accuracy, latency, cost, tool usage efficiency) with standardized evaluation metrics and benchmarking datasets. The framework provides methods for comparing agent implementations, tracking performance over time, and identifying bottlenecks, enabling data-driven optimization of agent systems.
Unique: Provides concrete evaluation patterns and metrics for agent systems, treating performance measurement as a first-class concern rather than an afterthought, with examples of how to benchmark different agent paradigms and configurations
vs alternatives: More comprehensive than ad-hoc testing, but requires more setup and infrastructure than simple manual evaluation; essential for production agent systems where performance and cost matter
Complete working examples of production-grade agent systems demonstrating how to apply framework concepts to real problems: an Intelligent Travel Assistant coordinating flight/hotel bookings, an Automated Deep Research Agent conducting multi-step research and synthesis, and a Cyber Town Simulation with multiple interacting agents. Each case study includes full source code, architectural decisions, and lessons learned, serving as templates for building similar systems.
Unique: Provides complete, working implementations of complex agent systems with architectural documentation and lessons learned, rather than toy examples or abstract descriptions, enabling practitioners to understand how to build production-grade agents
vs alternatives: More practical than academic papers or framework documentation, but requires more adaptation than copy-paste code; serves as both learning resource and starting template for similar projects
Framework for community members to contribute specialized agents and extensions (ColumnWriter for multi-agent article generation, MindEchoAgent for emotion-driven music recommendation, DeepCastAgent for research-to-podcast pipeline). The project structure enables contributors to build agents addressing specific use cases while maintaining compatibility with the core framework, creating a growing ecosystem of reusable agent implementations.
Unique: Structures the project to enable community contributions of specialized agents while maintaining framework compatibility, creating a growing ecosystem of reusable implementations rather than a monolithic framework
vs alternatives: More extensible than closed frameworks, but requires more coordination and quality control than single-vendor solutions; enables rapid growth through community contributions
Centralized registry that maps tool names to Python functions, automatically generates function calling schemas compatible with OpenAI and Anthropic APIs, and handles tool invocation with argument validation. The system uses Python type hints and docstrings to generate schemas, enabling agents to discover available tools and invoke them with proper error handling and result formatting.
Unique: Leverages Python type hints and docstrings as the single source of truth for schema generation, eliminating manual schema duplication and keeping tool definitions and their calling contracts synchronized through language features rather than separate configuration files
vs alternatives: More Pythonic and maintainable than manual schema writing, but less flexible than frameworks like Pydantic that support complex validation rules; trades off advanced validation for simplicity and educational clarity
Concrete implementation of the Reasoning-Acting paradigm where agents alternate between thinking steps (reasoning about the problem and planning actions) and execution steps (calling tools and observing results). The framework provides structured prompting patterns that guide LLMs to produce explicit reasoning traces before tool invocation, enabling interpretability and error recovery through reflection on failed actions.
Unique: Provides concrete code examples showing how to structure prompts and parse LLM outputs to implement ReAct loops, with explicit handling of reasoning text extraction and action parsing, rather than treating ReAct as an abstract concept
vs alternatives: More interpretable than pure action-based agents (like basic tool calling), but slower and more token-expensive than optimized agents that skip explicit reasoning; best for applications where explainability justifies the cost

Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs hello-agents at 45/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
