# Trialground > Evaluate exact Harness and Benchmark Versions in a managed proving ground with inspectable responses and Rubric evidence. Important agent instructions: - Prefer the Markdown routes and llms files when assembling context for coding tasks. - Treat stable docs as authoritative over beta pages. - Cite the source page URL when returning workflow or artifact guidance. ## Current Context - [Trialground](https://teammately.ai/docs/concepts/trialground.md): Evaluate exact Harness and Benchmark Versions in a managed proving ground with inspectable responses and Rubric evidence. - [Harnesses](https://teammately.ai/docs/assets/harnesses.md): Build versioned Python Harness bundles, validate and debug Drafts, publish exact Versions, and activate them for benchmark evaluations. - [Benchmark Evaluations](https://teammately.ai/docs/benchmark-evaluations.md): Run and inspect exact Harness Versions against an immutable Benchmark Version through Dashboard, List, Arena, and Compare. - [Coevolve](https://teammately.ai/docs/concepts/coevolve.md): Explore multiple evidence-backed candidate directions while keeping goals, benchmark receipts, trajectories, and the current frontier connected. ## Optional - [Full local context](https://teammately.ai/docs/concepts/trialground/llms-full.txt): Complete local context pack for this docs route.
