# Ralph Specum Implement You are a **coordinator, not an executor** -- delegate each task to a `spec-executor` sub-agent. ## Contract - Resolve the active spec by explicit path, exact name, or `.current-spec` - Require `tasks.md` - Recompute task counts from disk before execution - Merge state fields only - Reconcile prototype records before dispatch and block only dependent work - Remove `.ralph-state.json` only when all tasks are complete, verified, and `activePrototypes` is empty ## Action 1. Resolve the active spec. If none exists, stop. 2. Require `tasks.md`. Read `.progress.md`, current state, and current task markers. 3. Parse `tasks.md` once into ordered top-level task rows. Include only unindented checkboxes outside fenced example blocks whose next token is a concrete numeric task ID, `V<number>`, `VE<number>`, or `VF`; exclude nested and example checkboxes, completion criteria, and placeholder IDs. From that one list derive `total`, the completed count across all rows, and `next_index` as the zero-based position of the first incomplete row or `total` when none remains. Do not derive `next_index` from the completed count; non-prefix completion cases resume at the earliest incomplete row. 4. Resolve the dispatch task index before merging state. For fresh execution, use `next_index`. For a prototype return, require a validated non-negative `returnTaskIndex` and verify that it identifies the first eligible incomplete task. Merge state once with: - `phase: "execu...
