Analyzes pull request diffs using pluggable LLM providers (OpenAI, Anthropic, Ollama, Azure, etc.) to generate structured code review feedback. Routes requests to configured models via a provider abstraction layer that normalizes API calls, handles streaming responses, and manages token limits per model. Supports both synchronous review and asynchronous batch processing for large changesets.
Unique: Implements a provider-agnostic LLM abstraction layer that normalizes API differences across OpenAI, Anthropic, Ollama, Azure, and others, allowing teams to swap models without changing review logic. Uses prompt templating with model-specific optimizations (e.g., different system prompts for Claude vs GPT-4) rather than one-size-fits-all prompts.
vs alternatives: More flexible than GitHub Copilot (vendor-locked to OpenAI) and more cost-effective than Codium's proprietary service by supporting local/cheaper models while maintaining review quality through model selection.
Parses unified diff format to extract changed lines, identify affected functions/classes, and build a minimal code context window that includes only relevant surrounding code. Uses AST-aware language detection to understand code structure and avoid reviewing auto-generated or vendored code. Implements smart filtering to exclude low-risk changes (whitespace, comments, formatting) from detailed review.
Unique: Uses language-specific AST parsers (via tree-sitter or language-native libraries) to understand code structure and identify affected scopes, rather than naive line-based diff analysis. Implements multi-stage filtering: first removes formatting-only changes, then scopes context to affected functions, then applies language-specific heuristics to exclude generated code.
vs alternatives: More precise than simple line-counting approaches (e.g., GitHub's native review suggestions) because it understands code structure and can exclude low-value changes, reducing review noise and token waste.
Performs language-specific analysis using Abstract Syntax Tree (AST) parsing and semantic understanding for supported languages (Python, JavaScript, Java, Go, Rust, C++, etc.). Extracts code structure (functions, classes, imports, dependencies) to provide context-aware feedback that understands code semantics rather than just text patterns. Uses language-specific linters and type checkers (if available) to enhance analysis.
Unique: Uses language-specific AST parsers (tree-sitter, language-native libraries) to extract code structure and semantics, enabling analysis that understands code meaning rather than just text patterns. Integrates with language-specific linters and type checkers for enhanced accuracy.
vs alternatives: More accurate than text-based analysis because it understands code structure and semantics, enabling detection of issues that require semantic understanding (e.g., type mismatches, unused imports, scope violations).
Caches analysis results for unchanged code sections to avoid redundant LLM calls and parsing. Uses content hashing to detect changes and invalidate cache entries only when necessary. Implements incremental analysis that focuses on changed sections while reusing cached results for unchanged code, reducing latency and token usage by 30-50% for typical PRs.
Unique: Implements content-based caching with fine-grained invalidation at the code section level (function, class, etc.) rather than file-level, enabling reuse of analysis results even when files are modified. Uses incremental analysis to focus LLM calls on changed sections only.
vs alternatives: More efficient than full re-analysis because it caches results for unchanged code and focuses analysis on changed sections, reducing latency and token usage by 30-50% for typical PRs.
Analyzes code changes to detect new or modified functions, classes, and APIs, then generates documentation (docstrings, JSDoc, Javadoc, etc.) in the appropriate language format. Validates API contracts (function signatures, return types, exceptions) against documentation to detect inconsistencies. Suggests documentation updates when APIs change without corresponding documentation updates.
Unique: Generates language-specific documentation (docstrings, JSDoc, Javadoc) that matches the project's style and conventions, then validates API contracts against documentation to detect inconsistencies. Supports multiple documentation formats and languages.
vs alternatives: More comprehensive than generic documentation generators because it validates API contracts and detects inconsistencies, ensuring documentation stays in sync with code changes.
Analyzes PR title and description against the actual code changes to identify gaps, inconsistencies, or missing context. Uses LLM to generate improved descriptions that accurately reflect the changes, suggest better titles, and identify missing information (e.g., breaking changes, migration steps). Integrates with PR metadata to validate descriptions against commit messages and issue references.
Unique: Correlates PR metadata (title, description, commits, diff) to detect inconsistencies and gaps, then uses LLM to generate contextually-aware improvements rather than generic templates. Includes validation rules (e.g., checking for breaking change markers) to flag high-risk PRs.
vs alternatives: More intelligent than template-based PR checkers because it analyzes actual code changes and detects when descriptions are misleading or incomplete, not just checking for presence of sections.
Examines code changes to identify untested or under-tested logic, then suggests test cases or test file locations where coverage should be added. Parses existing test files to understand testing patterns and conventions, then generates test suggestions that match the project's style. Integrates with coverage reports (if available) to prioritize high-impact areas.
Unique: Analyzes existing test files to extract testing patterns (assertion styles, mocking conventions, test structure) and generates suggestions that match the project's conventions rather than generic boilerplate. Uses AST analysis to identify untested code paths and correlates them with coverage data.
vs alternatives: More actionable than generic coverage reports because it suggests specific test cases and matches project conventions, rather than just reporting coverage percentages.
Scans PR diffs for common security vulnerabilities (SQL injection, XSS, hardcoded secrets, insecure cryptography, etc.) using pattern matching and LLM-based semantic analysis. Integrates with SAST tools (if available) and cross-references against known vulnerability databases. Provides severity ratings and remediation suggestions for each finding.
Unique: Combines pattern-based detection (regex, AST patterns) with LLM-based semantic analysis to catch both obvious vulnerabilities (hardcoded secrets, SQL injection) and subtle ones (insecure randomness, weak cryptography). Integrates with SAST tools for enhanced coverage without duplicating detection logic.
vs alternatives: More comprehensive than standalone secret scanners because it detects multiple vulnerability types (secrets, injection, crypto, etc.) in a single pass, and provides LLM-generated remediation suggestions rather than just flagging issues.

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 PR-Agent at 23/100.

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.
