Supported agents: The site names Claude Code, Codex, OpenCode, Hermes, OpenClaw, NanoClaw, Kimi Code, and Pi.
Run records: Tangle records model calls, tool use, timing, tokens, and cost so a run can be inspected after the agent finishes.
Analysis: Tangle Intelligence is described as a way to analyze multiple runs for recurring failures and expensive steps.
Review outputs: The site describes turning measured findings into a pull request, issue, skill proposal, or team summary for human review.
Model router: Tangle Router offers one API for model inference, supports the OpenAI and Anthropic SDKs and plain fetch, and says it routes to 66+ providers.
