# Work and Evolve > Choose bounded implementation work or multi-branch evolutionary search with explicit epoch and provider authorization. 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 - [Work and Evolve](https://teammately.ai/docs/improve/work-and-evolve.md): Choose bounded implementation work or multi-branch evolutionary search with explicit epoch and provider authorization. - [Start an Improvement Session](https://teammately.ai/docs/improve/start-improvement-session.md): Start from benchmark evidence, prepare a measurable Goal Contract, and choose bounded Work or Evolve behavior. - [Goal Contracts](https://teammately.ai/docs/improve/goal-contracts.md): Bind an Improvement Session to exact targets, measurable objectives, constraints, and permitted intervention scope. - [Chronology, Trajectories, and Receipts](https://teammately.ai/docs/improve/chronology-and-trajectories.md): Read durable session events, safe narrated work segments, evaluation receipts, external handoffs, and usage evidence. ## Optional - [Full local context](https://teammately.ai/docs/improve/work-and-evolve/llms-full.txt): Complete local context pack for this docs route.
