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 before loading context. Pure consultation and small isolated edits do not need a task or a task-creation question. Preserve risk boundaries in AGENTS.md.
2. For tracked work, obtain current task and status from already supplied context, or run get_context.py when missing or stale. Do not enumerate unrelated journals and historical tasks.
3. Read the workflow Phase Index and current step on demand. Read the current PRD, then design and implementation notes if needed. Reuse unchanged material already loaded in this session.
4. With no task, obtain task-creation consent for non-trivial work unless already authorized. With a planning task, complete missing decisions; once its plan is approved, start and execute without asking again. An existing PRD alone is not proof of approval.
5. For implementation load trellis-before-dev; for verification load trellis-check. Load spec indexes only for affected layers and follow relevant links, not every guideline.

The project workflow and task status are authoritative over legacy user-level Trellis skills. Missing optional tools require a supported fallback or a precise limitation report, not repeated permission requests.
