Start Session

Initialize a Trellis-managed development session. This platform has no session-start hook, so manually load the equivalent compact context by following these steps.

---

Step 1: Current state

Identity, git status, current task, active tasks, journal location.

{{PYTHON_CMD}} ./.trellis/scripts/get_context.py

If this output includes a line beginning `Trellis update available:`, copy the full line verbatim when summarizing session context. Do not shorten operational command hints.

Step 2: Workflow overview

Compact Phase Index, request triage rules, planning artifact contract, and the step-detail command.

{{PYTHON_CMD}} ./.trellis/scripts/get_context.py --mode phase

Full guide in `.trellis/workflow.md` (read on demand).

Step 3: Guideline indexes

Discover packages + spec layers, then read each relevant index file.

{{PYTHON_CMD}} ./.trellis/scripts/get_context.py --mode packages
cat .trellis/spec/guides/index.md
cat .trellis/spec/<package>/<layer>/index.md   # for each relevant layer

Index files list the specific guideline docs to read when you actually start coding.

Step 4: Decide next action

From Step 1 you know the current task and status. Check the task directory:

• **Active task status `planning` + no `prd.md`** → Phase 1.1. Load the `trellis-brainstorm` skill.
• **Active task status `planning` + `prd.md` exists** → stay in Phase 1. Lightweight tasks can be PRD-only; complex tasks need `design.md` + `implement.md`. Load the relevant Phase 1 step detail before `task.py start`.
• **Active task status `in_progress`** → Phase 2 step 2.1. Load the step detail:

  {{PYTHON_CMD}} ./.trellis/scripts/get_context.py --mode phase --step 2.1 --platform {{CLI_FLAG}}

• **No active task** → classify first. For simple conversation / small task, ask only whether this turn should create a Trellis task. For complex work, ask whether you may create a Trellis task and enter planning. If the user says no, skip Trellis for this session.

Skill routing (quick reference)

| User intent | Skill | |---|---| | New feature / unclear requirements | `trellis-brainstorm` | | About to write code | `trellis-before-dev` | | Done coding / quality check | `trellis-check` | | Stuck / fixed same bug multiple times | `trellis-break-loop` | | Learned something worth capturing | `trellis-update-spec` |
