# Weave > Construct deliberate challenge sets from coverage structure, canonical cases, variants, multimodal materials, and supported worlds. 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 - [Weave](https://teammately.ai/docs/concepts/weave.md): Construct deliberate challenge sets from coverage structure, canonical cases, variants, multimodal materials, and supported worlds. - [Coverage Engineering](https://teammately.ai/docs/coverage-engineering.md): Design the behavior space a benchmark must represent and connect reusable project facets to benchmark coverage work. - [Assets](https://teammately.ai/docs/assets.md): Manage reusable project cases, worlds, project tools, harnesses, weights, comparison directions, and review screens before selecting them for benchmark work. - [Benchmark Datasets](https://teammately.ai/docs/benchmark-datasets.md): Select benchmark Cases, inspect representation, and freeze immutable Snapshots for reproducible evidence. ## Optional - [Full local context](https://teammately.ai/docs/concepts/weave/llms-full.txt): Complete local context pack for this docs route.
