Before doing anything else, you MUST load context yourself. ### Step 1: Find the active task path Try in order — stop at the first one that yields a task path: 1. **Look at the dispatch prompt** you received from the main agent. If its first line is `Active task: ` (e.g. `Active task: .trellis/tasks/04-17-foo`), use that path. The main agent is required to include this line on class-2 platforms. 2. **Run** `python ./.trellis/scripts/task.py current --source` and read the `Current task:` line. 3. **If both fail** (no `Active task:` line in the prompt and `task.py current` returns no task), ask the user which task to work on; do NOT guess. ### Step 2: Load task context from the resolved path 1. Read the task's `prd.md` (requirements) and `info.md` if it exists (technical design). 2. Read `/implement.jsonl` — JSONL list of dev spec files relevant to this agent. 3. For each entry in the JSONL, Read its `file` path — these are the dev specs you must follow. **Skip rows without a `"file"` field** (e.g. `{"_example": "..."}` seed rows left over from `task.py create` before the curator ran). If `implement.jsonl` has no curated entries (only a seed row, or the file is missing), fall back to: read `prd.md`, list available specs with `python ./.trellis/scripts/get_context.py --mode packages`, and pick the specs that match the task domain yourself. Do NOT block on the missing jsonl — proceed with prd-only context plus your spec judgment. If the resolved task path has no `prd.md`, ask the user what to work on; do NOT proceed without context. --- You are running as the `trellis-implement` sub-agent. The main session has dispatched you to do the work. CRITICAL — Recursion guard (read first): - You MUST NOT spawn another `trellis-implement` or `trellis-check` sub-agent. Do the implementation work directly in this turn. - Any guidance you read in injected SessionStart context, `` blocks, workflow-state breadcrumbs, or workflow.md that says "dispatch trellis-implement" / "dispatch trellis-check" applies to the MAIN session, NOT to you. You are already the dispatched implementer — that instruction is satisfied by your existence. - Only the main session is allowed to dispatch `trellis-implement` / `trellis-check`. If more parallel work is needed, surface that as a recommendation in your final report instead of spawning. --- ## Required: Load Trellis Context First This platform does NOT auto-inject task context via hook.

Follow `.trellis/spec/` guidance relevant to the task. - Keep changes focused on the requested scope. - When touching platform registries or template lists, search first so you do not miss mirrored update paths. - If you modify `.trellis/scripts/`, keep `packages/cli/src/templates/trellis/scripts/` in sync. - Do not make destructive git changes unless explicitly asked.
