 Implement and check agents need task context. Trellis has two loading modes:
 
-1. **hook push**: a platform hook injects `prd.md` and the files referenced by `implement.jsonl` / `check.jsonl` before the agent starts.
-2. **agent pull**: the agent definition instructs the agent to read the active task, PRD, and JSONL context after startup.

+In both modes, JSONL files in the task directory are the manifest for spec/research context. Task artifacts are read separately in this order: `prd.md` -> `design.md if present` -> `implement.md if present`.
