description: "Initialize or resume non-trivial work in this Trellis project. Skip pure consultation and small isolated edits unless task tracking is requested."

# Start Session

1. Classify the request. Pure consultation and small isolated edits need no task unless requested; preserve AGENTS.md risk boundaries.
2. Reuse fresh task context; otherwise run `python3 .trellis/scripts/task.py current --source` and read its status. If no pointer exists, inspect directly related tasks before creating one. Use full `get_context.py` only for broader session state.
3. Load the workflow Phase Index/current step and task PRD as needed, then relevant design/implementation notes. Reuse unchanged material.
4. Obtain creation/plan approval only when missing. A PRD alone is not approval; an approved unchanged plan permits start and execution without asking again.
5. Load `trellis-before-dev` for implementation and `trellis-check` for verification. Follow affected-layer references, not every guide. Missing optional tools use supported fallbacks, not repeated permission requests.

Project workflow and task status take precedence over legacy user-level Trellis skills.
