agentlint is an open-source CLI tool that provides real-time quality guardrails and linting for AI coding agents. It helps developers maintain code quality and safety by integrating with agentic coding workflows and enforcing best practices.
agent-rules-lint is an open-source CLI tool that checks and validates AI agent instruction files such as AGENTS.md, CLAUDE.md, and Copilot rules. It helps developers maintain clear, consistent, and error-free agent documentation and configuration files.
Lint, score, and optimize AI agent configuration files (CLAUDE.md, AGENTS.md, Cursor rules)
agenticlint is an open-source command-line linter that analyzes OpenAPI specifications to ensure they are safe and clear for use as MCP or AI-agent tools. It performs static analysis to identify potential issues, helping developers maintain secure and well-documented APIs.
TraceAgently is a real-time observability and monitoring platform designed specifically for AI agents. It provides developers with detailed, live traces of agent behavior, capturing each thought, tool call, tool result, and error as they occur. The platform addresses the challenge of managing and controlling AI agent runs, with features that allow users to monitor, analyze, and intervene in agent execution to prevent runaway costs and detect failures early. Key features include an automatic kill-switch that enforces per-trace cost limits, immediately terminating agents that exceed set thresholds to prevent excessive API charges. Loop detection is built in, identifying and stopping agents caught in infinite loops by monitoring repeated tool calls. The real-time trace viewer streams every event as the agent runs, complete with timestamps, token counts, and step-by-step costs, while trace comparison enables side-by-side analysis of different runs, highlighting changes in cost, duration, tokens, and events. Users can mark a successful run as "Golden" and compare future traces against it. The platform also offers Magic Fix, which sends a trace to Claude for automated diagnosis and suggested fixes, and cost tracking that estimates and reports the expense of each agent run. Email alerts notify users instantly when a kill-switch is triggered or a loop is detected. Error pattern detection groups and ranks recurring issues across runs, helping developers identify systemic problems before they impact end users. TraceAgently is framework-agnostic, supporting integration with LangChain, CrewAI, OpenAI, Claude, Gemini, LangGraph, AutoGen, or any custom Python or TypeScript agent loop. Integration requires only two lines of code using the provided SDKs for Python (via pip) or TypeScript (via npm). Pricing includes a free tier with up to 1,000 traces per month, 7-day data retention, and support for one agent, requiring no credit card. 50 per 1,000. TraceAgently is positioned as a dedicated observability tool for AI agent workflows, focusing on real-time intervention and detailed trace analysis.
agent-triage is an open source tool for ranking and diagnosing failures in multi-agent systems. It provides a CLI, web dashboard, OTLP receiver, and optional LLM-based root-cause analysis, helping AI engineers quickly identify and prioritize issues.
agent-log-verifier is a command-line tool for post-hoc analysis of AI agent session logs, particularly Claude Code JSONL transcripts. It helps AI engineers and maintainers detect mismatches between prompts and tool calls, improving agent reliability and debugging.
MCP server that diagnoses why your agent behaved the way it did, and how to fix it
ai-skill-lint is an open-source command-line tool that lints and validates AI instruction files, including skills, prompts, and agent specifications. It helps AI developers and prompt engineers maintain consistency and correctness in their agent workflows. The tool supports configurable rules and integrates with modern AI development pipelines.
