If settings.apply.executionMode ≠ ask (from 0.0), skip this question — use the configured mode directly, state it in one line, proceed to Phase 1.
Otherwise, use question tool with ONE question. Subagent mode is the recommended default for ALL changes — small, medium, and large. Inline mode exists only as a fallback for environments where subagent dispatch is unavailable. Phrase the question so this preference is unmistakable.

# 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 when `settings.apply.executionMode` is `ask`. NEVER read affected source code files into the main agent's context — pass PATHS to subagents who read them.

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
None justify re-reading artifacts, reading affected code into main context, editing spec/design, ignored failures, skipped reviewers, batched fixes, per-slice check-ins, fix-attempt #4, full-suite tests, commits, archive auto-trigger, verify-change handoff, batched scenario tests, skipped REFACTOR assessment, or cherry-picked project rules.

## Inputs
Already in conversation context (loaded by vanilla `/opsx-apply` steps 2-4):
* `proposal.md`, `spec.md` (or `specs/**/*.md`), `design.md`, `tasks.md`
* Output of `openspec status --change <name> --json`
* Output of `openspec instructions apply --change <name> --json`
Project standards (`AGENTS.md` / `CLAUDE.md` / `GEMINI.md`) — opencode auto-loads as project instructions; authoritative for code style, file organization, naming, build/test/lint commands.
Build files (`package.json`, `Cargo.toml`, `go.mod`, etc.) — source of lint/format/test commands for gates.
If artifacts NOT in context, surface error:
```
OpenSpec change artifacts are not in context. Run `/opsx-apply <change>` to load
them, then I will take over the implementation loop.
```
NEVER read source code outside what slices touch.

## Workflow
Four phases (0-3) plus hand-back. NEVER skip, merge, or reorder.
```text
[ ] Phase 0: Pre-Flight (verify inputs, discover commands, choose mode)
[ ] Phase 1: Dependency analysis & parallelism check
[ ] Phase 2: Per-slice execution loop
[ ] Phase 3: Whole-change review & final gate
```
**Flow:** Phase 0 → Phase 1 → (blocked? → suggest /opsx-continue, exit) → (all_done? → suggest /opsx-archive, exit) → Phase 2 per-slice: implementer → (DONE → spec-compliance review → code-quality review → per-slice gate → mark [x]) | (NEEDS_CONTEXT → provide, re-dispatch) | (BLOCKED → 4-step assessment → recoverable: retry | fundamental/3+ retries: pause and exit). After all slices → Phase 3: whole-change review + final gate → emulate vanilla step 7.
Reviewers cap at 3 fix cycles. Beyond 3 → STOP, artifacts wrong, escalate.
---
## Workflow Visibility (MANDATORY)
Display workflow phases via todowrite at start; update as phases complete. Add per-slice todos under Phase 2 once slicing is finalized.
---
## Core Principles
- **Take Over Step 6 Only** — vanilla owns steps 1-5 and 7; after Phase 3, emulate step 7 output and stop.
- **Trust The Artifacts** — earlier phases validated them; NEVER re-critique; implementation reveals a gap → escalate (pause/exit, suggest plus-design/plus-spec); never edit from inside this skill.
### Main Agent Context Hygiene (subagent mode ONLY)
In subagent mode, the main agent NEVER reads slice's affected source files — pass PATHS only. Subagents read files in their isolated context:
* Implementer: pass affected file paths. Implementer reads them.
* Spec-compliance reviewer: pass paths to changed files. Reviewer reads them.
* Code-quality reviewer: pass changed file paths. Reviewer diffs via `git diff HEAD`; falls back to reading files if git unavailable.
* Final reviewer: pass artifact paths + all changed file paths. Same diff strategy.
Artifacts (`proposal.md`, `spec.md`, `design.md`, `tasks.md`) are already in main context from vanilla — using them for subagent prompt excerpts is fine. Source code files are NOT.
- **Inline Mode Reading** (inline mode only) — main agent IS the implementer; reads files directly; reads project standards + affected files for Pre-RED; edits directly during TDD; self-reviews own changes; reviews cumulative diff at Phase 3. Each file read once.
- **Pre-RED Reading** (both modes) — before any code, implementer reads project standards (`AGENTS.md`/`CLAUDE.md`/`GEMINI.md` + referenced docs); enforced by `openspec-plus-tdd` Phase 0; follow every documented rule strictly, end-to-end (no cherry-picking).
### Strict TDD Through openspec-plus-tdd
**Iron Law: NO PRODUCTION CODE WITHOUT A FAILING TEST.** One test at a time — full cycle (RED → VERIFY-RED → GREEN → VERIFY-GREEN → REFACTOR) before starting next. Applies to all tests: acceptance (mandatory per Gherkin scenario) and granular (encouraged). REFACTOR assessment mandatory per test — skipping assessment is the violation, not skipping action.
### Implementation Principles For Both Modes
Apply in every slice:
1. **Think Before Coding** — surface assumptions, ask when uncertain, never silently pick between interpretations.
2. **Simplicity First** — minimum code that solves the problem; nothing speculative.
3. **Surgical Changes** — every changed line traces to a task in this slice; never improve adjacent code.
4. **Goal-Driven Execution** — each test—Gherkin or granular—is a verifiable goal; loop independently until it passes.
- **Code Style** — canonical rules in `openspec-plus-tdd` § Code Style Rules; code is self-documenting; comments are exceptional last resort.
- **Never Ignore Failing Tests** — `.skip`, `.todo`, `xtest`, `it.skip`, commented-out tests, or `--bail` shortcuts are anti-patterns; pre-mark gate blocks on any failure.
- **Continuous Execution** — do NOT pause between slices; pause only on BLOCKED (unrecoverable), 3+ failed fix cycles, or 3+ NEEDS_CONTEXT in a row.
- **No Commits** — vanilla doesn't commit; this skill doesn't either.
- **Resumability Is Free** — `openspec instructions apply` is the source of truth; re-running picks up at next pending slice.
- **Respect Project Standards** — `AGENTS.md`/`CLAUDE.md`/`GEMINI.md` capture lint/format/test commands, code style, file organization, naming conventions.
---
## Phase 0: Pre-Flight
### 0.0 Resolve Apply Config
Read `openspec/.plus/config.yaml` once (missing/unreadable/unrecognized value → default, zero behavior change): `settings.apply.executionMode` (`ask` default | `subagent` | `inline`, anything else → `ask` — skips 0.3 only for `subagent`/`inline`), `settings.apply.parallelism` (`ask` default | `always` | `never`, anything else → `ask` — skips 1.4 only for `always`/`never`).
### 0.1 Verify In-Context Artifacts
Confirm vanilla's steps 2-4 produced these in conversation context:
* Output of `openspec instructions apply --change <name> --json` showing `state`, `tasks`, `contextFiles`
* Content of `proposal.md`, `spec.md` / `specs/**/*.md`, `design.md`, `tasks.md`
If absent → surface error above, stop.
State handling:
* `"blocked"` → suggest `/opsx-continue`, exit
* `"all_done"` → suggest `/opsx-archive`, exit
* `"ready"` → continue
### 0.2 Discover Pre-Mark Gate Commands
Identify ONCE at Phase 0 (used by per-slice + final gates):
* **Lint** — e.g., `bun run lint`
* **Format** — e.g., `bun run format`
* **Test** — e.g., `bun test`
* **Other** — type-check (`tsc --noEmit`), schema-check, build-check, etc.
Discovery order:
1. `package.json` `"scripts"` (or `Cargo.toml`, `go.mod`, `pyproject.toml`)
2. `AGENTS.md` / `CLAUDE.md` / `GEMINI.md` documented commands
3. Project README or build file conventions
Missing or ambiguous → ask user ONCE via question tool.
### 0.3 Mode Question (MANDATORY, blocking)
If `settings.apply.executionMode` ≠ `ask` (from 0.0), skip this question — use the configured mode directly, state it in one line, proceed to Phase 1.
Otherwise, use question tool with ONE question. **Subagent mode is the recommended default for ALL changes — small, medium, and large.** Inline mode exists only as a fallback for environments where subagent dispatch is unavailable. Phrase the question so this preference is unmistakable.
