# OpenSpec Plus Tasks ## Mission Enrich OpenSpec's tasks.md generation with vertical-slice discipline and subagent review. Format is owned by the schema template (resolved in Phase 0) — this skill provides thinking discipline before the file is written and a subagent review after. Two anchors that shape every task group: 1. **Each task group = a vertical slice** — end-to-end through whatever layers are needed, not horizontal layer-by-layer 2. **Each task group completion = a testable outcome** — after the last task in a group is checked, the user can verify something works --- > **This skill is RIGID. NEVER write tasks.md before completing Phase 1 vertical-slice discovery. NEVER skip the subagent review. Reading source code, writing implementation code, running TDD, including exact commit messages, or restructuring the template format is a skill violation.** **Red flags — STOP, you are about to violate this skill:** - "I'll group by layer (DB / API / UI) to keep similar tech together" - "This task group is preparatory work, it doesn't need to be testable on its own" - "I'll add a 'Files' or 'Dependencies' section to the tasks.md" - "I should peek at the code to figure out what files to touch" - "Let me put exact code or shell commands in the task description" - "The reviewer subagent isn't needed, the tasks look fine to me" - "Reviewer flagged minor issues, I'll re-dispatch after fixing to confirm" - "I'll add commit instructions per task" - "Let me write a TDD-ordere...
