`/architect` — design a new project end to end

You are being invoked as the `/architect` slash command. This file sets the **mode**. It does not contain the interview — the interview lives in `questions/` and is the single source of truth.

**Read these before saying anything to the user:**

• Plugin install: `${CLAUDE_PLUGIN_ROOT}/skills/architect/SKILL.md`
• Clone install: `./CLAUDE.md` at the repo root — the clone-mode mirror of the skill. Same rules,

same state machine, repo-relative paths, and the subagent work done inline.

Read the skill end to end, then execute the four phases exactly as written there.

Mode

| Setting | Value | |---|---| | Entry | Greenfield — nothing exists yet | | Depth | Full 4-phase interview | | Question budget | Max 3 per message, conversational | | Output | Bundle or single file — **ask at phase-4 Step 2**, recommend bundle. Both land in the user's cwd under `./blueprints/`: `./blueprints/<project-slug>/` for a bundle, `./blueprints/<project-slug>-blueprint.md` for a single file. | | Gate | `blueprint-validator` must return **PASS** before you hand anything over |

`${CLAUDE_PLUGIN_ROOT}/questions/phase-4-generate.md` Step 3 is the authority on the emitted tree — do not reproduce it from memory here. One thing worth repeating: **`.claude/commands/` is never emitted into a generated project.** A slash command only fires when a human types it, and an autonomous builder types nothing; repeatable project workflows go in `.claude/skills/<name>/SKILL.md`.

Phase pointers — read, never paraphrase from memory

| Phase | Read | Produces | |---|---|---| | 1 · Discovery | `${CLAUDE_PLUGIN_ROOT}/questions/phase-1-discovery.md` | The shape → `${CLAUDE_PLUGIN_ROOT}/knowledge/shapes/<shape>.md` | | 2 · Deep dive | `${CLAUDE_PLUGIN_ROOT}/questions/phase-2-branches.md` | Runtime track + capability set | | 3 · Architecture | `${CLAUDE_PLUGIN_ROOT}/questions/phase-3-confirmation.md` | Confirmed stack, signed off by the user | | 4 · Generate | `${CLAUDE_PLUGIN_ROOT}/questions/phase-4-generate.md` | The bundle, then the validator |

Supporting files, loaded on demand and only when the phase calls for them: `knowledge/runtime-tracks/`, `knowledge/capabilities/`, `knowledge/stack-compatibility.md`, `knowledge/skills-registry.md`, `templates/blueprint-template.md`, `templates/claude-md-template.md`, `templates/tasks-schema.md`, `templates/epic-template.md` — all under `${CLAUDE_PLUGIN_ROOT}/`.

Arguments

`$ARGUMENTS` is an optional project description. It **seeds** Phase 1 Q1 — it does not replace it.

• Empty → open Phase 1 with Q1 as written.
• Non-empty → treat it as the answer to Q1. Play back the shape you read from it in one line, then

ask the next 2 unanswered Phase 1 questions.

A description in the argument never authorizes skipping Phases 2 and 3. If the user wants speed, that is `/architect-quick`.

Subagents

Dispatch these with the `Task` tool — do not do their work inline.

| Agent | When | File | |---|---|---| | `stack-researcher` | Phase 3, once the track is chosen — verify every pin against the live registry | `${CLAUDE_PLUGIN_ROOT}/agents/stack-researcher.md` | | `blueprint-writer` | Phase 4 — compose the bundle from the confirmed architecture | `${CLAUDE_PLUGIN_ROOT}/agents/blueprint-writer.md` | | `blueprint-validator` | Phase 4, after writing — the gate | `${CLAUDE_PLUGIN_ROOT}/agents/blueprint-validator.md` |

If the validator returns FAIL, fix the bundle and re-run it. Never hand the user a failing bundle with an apology attached.

The rules that matter here

1. **No blueprint before Phase 3 is confirmed.** The user says go, or you keep designing. 2. **Every build step carries an observable "Done when".** WHEN `<trigger>` THE SYSTEM SHALL `<observable response>`. "It works" is not a criterion. 3. **The bundle is self-contained.** A Claude Code instance with zero context builds from it without asking a single clarifying question. 4. **Write to the user's cwd, never inside the plugin.** The plugin cache is not a workspace. 5. **Detect the user's language from their first message** and stay in it — interview and bundle. 6. **Never hard-depend on a skill.** Not installed → fall back to the knowledge base and `WebFetch`/`WebSearch`, say so in one line, keep going.

After completion

Print the bundle path, the task count, the first task id, and one line: run `/architect-next` from the **target project root** to start building. Single-file mode has no `tasks.json`, so say that resume is manual and hand over the path alone.
