blueprint:onboard

ASSUME USER WANT FULL INTEGRATION - DO NOT ASK FOR SCOPE OF ONBOARDING

DO NOT ask "Would you like me to...", offer numbered options, or ask what to create. DO analyze the repo and create the full Blueprint structure now.

If existing documentation exists, CREATE BLUEPRINT STRUCTURE ANYWAY. Do not ask permission.

TOOL USAGE: Use AskUserQuestion for rationale questions with structured options. DO NOT ask for scope, we always do full Blueprint setup.

Onboard Repository

COMMAND: Analyze repo, show plan, then create full Blueprint structure.

Execute

1. Enter plan mode - Call EnterPlanMode tool first
2. Detect agent instructions file - See "CLAUDE.md / AGENTS.md Detection" below
3. Read package.json, README.md, [agent instructions file], docs/
4. Extract tech decisions and rationale from existing docs
5. Show plan - List exactly what will be created (see format below)
6. Exit plan mode - Call ExitPlanMode when ready
7. Gather rationale - For each tech without rationale, ask user (see format below)
8. Create all Blueprint files (including agent instructions)
9. Clean up existing documentation - Blueprint files are source of truth. Other docs (including CLAUDE.md and other agent instructions) reference these files rather than duplicating (keep brief summary + reference to ADR or spec)
10. Clean up long code comments referencing ADRs or specs instead of explaining rationale inlined in code
11. Report what was created

CLAUDE.md / AGENTS.md Detection

Repositories may have CLAUDE.md, AGENTS.md, both, or neither. CRITICAL: Check for symlinks FIRST to avoid breaking the link relationship.

Step 1: Check for symlinks FIRST

ls -la CLAUDE.md AGENTS.md 2>/dev/null

Look for -> in the output which indicates a symlink:

• CLAUDE.md -> AGENTS.md means CLAUDE.md is a symlink to AGENTS.md
• AGENTS.md -> CLAUDE.md means AGENTS.md is a symlink to CLAUDE.md

Step 2: Determine action based on priority order

Priority	Scenario	Detection	Action
1	Symlink exists	ls -la shows ->	Update the TARGET file only. NEVER delete or recreate either file.
2	One references other	File contains "See CLAUDE.md" or "See AGENTS.md"	Update the referenced file only
3	Only CLAUDE.md exists	File exists, no AGENTS.md	Update CLAUDE.md
4	Only AGENTS.md exists	File exists, no CLAUDE.md	Update AGENTS.md
5	Both exist independently	Both files, no symlink, no reference	Update both with same content
6	Neither exists	Neither file found	Create CLAUDE.md (default)

⚠️ CRITICAL: If a symlink exists, you MUST:

• Identify which file is the symlink and which is the target
• Only edit/update the TARGET file (the one being pointed to)
• NEVER delete either file - this would break the symlink relationship
• NEVER use Write tool on the symlink - use Edit on the target instead

Step 3: Record decision In the plan output, include:

Agent instructions: [CLAUDE.md | AGENTS.md] (target of symlink) | both

Plan Format (show before creating)

I will create:

ADRs:
- ADR-001: [tech] as [category] - [rationale or "TBD"]
- ADR-002: [tech] as [category] - [rationale or "TBD"]

Specs:
- docs/specs/product.md
- docs/specs/tech-stack.md
- docs/specs/boundaries.md

[Call ExitPlanMode to proceed]

ADR Template (inline for non-interactive execution)

status: Active

# ADR-NNN: [Choice] as [CATEGORY]

## Context
[What problem are we solving? What constraints exist?]

## Options Considered
### Option 1: [Alternative A]
- Pro: [advantage]
- Con: [disadvantage]

## Decision
We chose **[CHOICE]** because [primary motivation].

## Consequences
**Positive:**
- [benefit]

**Negative:**
- [tradeoff]

## Related
- Tech stack: [docs/specs/tech-stack.md](../specs/tech-stack.md)

Status values: Draft, Active, Superseded, Deprecated

ADR Format Enforcement (CRITICAL)

MANDATORY: Use the exact format above. DO NOT deviate.

DO NOT use	USE instead
## Status with "Accepted" in body	YAML frontmatter status: Active
**Benefits:**	**Positive:**
**Trade-offs:**	**Negative:**
## References	## Related
Omitting Options Considered	Include ## Options Considered

Validation checklist before writing ADR:

• Has YAML frontmatter with status: and date:
• Title format: # ADR-NNN: [Choice] as [CATEGORY]
• Has ## Options Considered section
• Uses **Positive:** and **Negative:** (not Benefits/Trade-offs)
• Ends with ## Related (not References)

Rationale Suggestions

When rationale is missing, use AskUserQuestion with context-aware options:

Technology	Suggested Rationales
React/Vue/Angular	Team familiarity; Large ecosystem; Component library compatibility; Industry standard
Next.js/Nuxt	SSR requirements; Full-stack capabilities; Team familiarity
Express/Fastify	Team familiarity; Mature ecosystem; Performance requirements
PostgreSQL	ACID compliance; Team familiarity; JSON support; Relational model
MongoDB	Document model fits data; Schema flexibility; Team familiarity
TypeScript	Type safety; Better IDE support; Reduced runtime errors

AskUserQuestion Format

Batch up to 4 technologies per question:

{
  "questions": [
    {
      "question": "Why was React chosen for the frontend?",
      "header": "React",
      "options": [
        {"label": "Team familiarity", "description": ""},
        {"label": "Large ecosystem", "description": ""},
        {"label": "Component library compatibility", "description": ""},
        {"label": "Skip for now", "description": "Mark as TBD"}
      ],
      "multiSelect": true
    }
  ]
}

• Selected options → Combine into rationale
• "Skip for now" → Mark as TBD
• Custom text → Use verbatim

Output Format

Created Blueprint structure:
- X ADRs (Y with rationale, Z marked TBD)
- docs/specs/product.md
- docs/specs/tech-stack.md
- docs/specs/boundaries.md
- [CLAUDE.md | AGENTS.md | both] (agent instructions)

TBD sections can be refined by running this skill again.

If Structure Already Exists

1. List what exists
2. Create any missing files
3. Ensure that the structure matches and these instructions
4. Report additions

Do not ask what to focus on. Create what's missing.

Questions

Use AskUserQuestion for rationale gaps (see format above).

Simple text questions allowed for:

• "Who are the users?" - if not in README
• "Any specific boundary rules?" - for boundaries.md

Never ask: "What would you like to create?" or "Full/partial setup?"
