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 mode). Pass paths. Subagent reads. (Inline mode is different — main agent reads directly.)
• "Critique the spec/design before starting" — done; trust them
• "Fix the spec/design from here while implementing" — escalate, don't edit
• "Mark the test .skip to move on" — never. Failing tests block progress
• "Slice is small, skip the spec-compliance reviewer" — never
• "Implementer's report says DONE, good enough" — verify with reviewer subagents
• "Both reviewers found issues, fix simultaneously" — spec-compliance first, re-review, then code-quality
• "Reviewing is generic, I'll write the review prompt myself" — NO. Every reviewer dispatch reads its *-prompt.md and sends the body verbatim; improvising it is the #1 failure mode
• "This prompt is long, I'll tighten it / drop the obvious parts when passing it on" — NO. Copy the template's prompt: block verbatim, substitute only {PLACEHOLDER}s. Every bullet is load-bearing; simplifying silently strips instructions from the subagent
• "Should I continue to the next slice?" — never ask. Continuous unless BLOCKED
• "Three fixes failed, try a fourth" — STOP. Artifacts wrong. Pause and exit
• "Run all tests instead of just affected" — wastes time; per-slice gate is scoped
• "Commit as I go" — vanilla doesn't commit; we don't either
• "Run /opsx-archive once everything is done" — only suggest, never auto-trigger
• "Run openspec-verify-change as part of final gate" — out of scope
• "Implementer wrote all tests upfront, that's fine" — TDD violation. One test at a time.
• "Implementer skipped REFACTOR because nothing to refactor" — refactor assessment is mandatory; skipping the assessment is the violation, not the skipping of action
• "AGENTS.md has many rules, implementer applied the ones that felt relevant" — cherry-picking the project's documented rules. Follow them strictly, end-to-end.
• "Implementer did test 1 RED-GREEN-REFACTOR correctly, then batched the rest" — the per-test state machine applies to EVERY test, not just the first
• "Implementer only wrote acceptance tests (one per Gherkin scenario), skipped all unit/edge tests" — acceptance coverage is mandatory but granular tests are encouraged for non-trivial branches, edges, error paths
