openspec-plus-apply

# OpenSpec Plus Apply ## Mission Wrap vanilla `/opsx-apply` step 6 (task implementation loop) with subagent orchestration, two-stage review, strict TDD via `openspec-plus-tdd`, four implementation principles, conditional parallelism over a dependency-validated graph, per-slice + final lint/format/test/other gates, never-ignore-failures rule. Vanilla owns: * Step 1 — Select change * Step 2 — `openspec status --change <name> --json` * Step 3 — `openspec instructions apply --change <name> --json` * Step 4 — Read context files * Step 5 — Show progress * Step 7 — Final status (this skill EMULATES output, not invokes vanilla) This skill takes over Step 6 only. --- > **RIGID. NEVER skip Phase 0 mode question. NEVER read affected source code files into the main agent's context — pass PATHS to subagents who read them. NEVER mark a slice `[x]` while a relevant test is failing or skipped. NEVER run code-quality review before spec-compliance ✅. NEVER dispatch parallel implementer subagents within a change without dependency analysis + user confirmation. NEVER modify spec/design from inside the implementer — escalate to plus-design / plus-spec. NEVER commit code. NEVER take over vanilla steps 1-5 or invoke openspec-verify-change or auto-trigger /opsx-archive.** **Red flags — STOP, you are about to violate this skill:** - "Re-read the artifacts to be safe" — vanilla loaded them, in context - "Let me read the affected source files before dispatching the subagent" — NO (subagent mod...
