maestro:blueprint

Maestro Blueprint

Generate two artifacts for every blueprint in the maestro project:

1. Plan spec (.md) -- maestro-format plan saved to .maestro/plans/{feature-name}.md
2. Visual blueprint (.html) -- interactive HTML presentation saved to ~/.agent/diagrams/{feature-name}-blueprint.html

The .md plan follows maestro conventions and integrates with tracks, missions, and the existing planning workflow. The .html is the visual version of the same content.

Workflow

1. Explore (Subagents)

Before generating anything, understand the affected codebase areas. Launch parallel explore subagents.

Maestro-specific areas to check:

• src/features/<name>/ -- feature-scoped code; each feature is a bounded context with its own commands/, usecases/, domain/, ports/, adapters/, services.ts, and index.ts public surface
• src/infra/ -- plumbing that isn't a feature (init, doctor, status, install, update, uninstall, mission-control commands; config and git ports/adapters)
• src/shared/ -- generic utilities with no domain knowledge (lib/ for fs, yaml, shell, output; domain/ for IDs, UI config; top-level errors.ts, version.ts)
• src/tui/ -- TUI rendering if the change affects Mission Control
• skills/built-in/ -- if the change affects built-in skills
• .maestro/context/ -- read product.md and tech-stack.md for project context
• .maestro/tracks/ -- check for related existing tracks
• tests/ -- existing test patterns

What to look for:

• Existing implementations that can be reused
• The feature-folder layout: cross-feature imports must go through @/features/<name> (the feature's index.ts); deep paths into another feature are forbidden and enforced by bun run check:boundaries
• The hexagonal pattern inside each feature: port -> adapter -> usecase -> command -> test
• Conventions from AGENTS.md (types, naming, async, imports, feature-folder layout)
• Files that will need modification
• Related tracks or plans already in .maestro/

2. Synthesize and Decide

After subagents report back, synthesize findings. Determine depth level:

Level	When	Sections
Light	1-2 files, obvious change	Context, File Changes, Verification
Standard	Feature spanning several files	Context, Critical Files, Phases, Verification
Full	Architectural change, new command/tool, cross-cutting	All sections including Design Decisions, Risks

If a structural fork exists (e.g., "should this be a port+adapter or a direct implementation?"), ask the user after exploration. Reference specific code you found.

3. Write the Plan Spec (.md)

Save to .maestro/plans/{feature-name}.md. Follow the maestro plan format:

# Blueprint: Feature Name

> One-line summary.

## Context

What exists today, what's broken/missing, what the world looks like after.
Include motivation -- why this change matters for maestro.

## Critical Files

| File | Role | Change |
|------|------|--------|
| `src/features/<name>/commands/foo.command.ts` | CLI command | New |
| `src/features/<name>/usecases/foo.usecase.ts` | Business logic | New |
| `src/features/<name>/ports/foo.port.ts` | Port interface | New |
| `src/features/<name>/adapters/foo.adapter.ts` | Adapter | New |
| `src/features/<name>/services.ts` | Feature composition | Wire new adapter |
| `src/features/<name>/index.ts` | Public surface | Export new command/types |
| `src/services.ts` | Composition root | Wire feature services (if new feature) |
| `src/index.ts` | CLI root | Add command registration |

## Design Decisions

**Decision 1: Why X over Y**
- Considered: approach A, approach B
- Chose: approach A because [reason]
- Trade-off: [what we give up]

## Phases

### Phase 1: Phase Name (~duration)

**Delivers:** What this phase produces that can be verified.

#### Tasks

1. **Task 1.1: Task name**
   - Files: `src/path/file.ts`
   - Description: What to do
   - _Acceptance: what proves this works_

2. **Task 1.2: Task name**
   - Files: `src/path/file.ts`
   - Description: What to do
   - _Acceptance: criteria_
   - _Depends on: Task 1.1_

#### Test Plan
- Unit: `bun test tests/unit/foo/`
- Integration: what to test

### Phase 2: ...

## Dependencies

## Risks

| Risk | Impact | Likelihood | Mitigation |
|------|--------|------------|------------|
| Specific risk | High/Med/Low | High/Med/Low | What to do |

## Verification

- [ ] Build: `bun run build && ./dist/maestro --version`
- [ ] Tests: `bun test`
- [ ] TUI (if applicable): `maestro mission-control --render-check --size 120x40`
- [ ] CLI: `maestro <command-under-test>`
- [ ] Release: `bun run release:local && command -v maestro && maestro --version` (if user-facing)

4. Generate the Visual Blueprint (.html)

Read the reference template at ./templates/blueprint-full.html before generating. Also read the CSS patterns at ./references/css-patterns.md.

The HTML contains the same content as the .md plan but presented visually with:

• KPI summary cards (files, phases, LOC, risk)
• Architecture diagram (Mermaid with zoom controls)
• Phase timeline
• Collapsible per-phase details with file changes and tasks
• Dependency DAG (if full depth)
• Risk matrix table (if full depth)
• Verification checklist

For Mermaid theming and libraries, read ./references/libraries.md. For responsive navigation (4+ sections), read ./references/responsive-nav.md. For detailed guidance on each section's content, read ./references/sections-guide.md.

Save to ~/.agent/diagrams/{feature-name}-blueprint.html.

5. Style

Follow the visual-explainer quality bar:

• Distinctive Google Fonts pairing (never Inter/Roboto/Arial)
• CSS custom properties for full light/dark theme support
• Semantic color naming (--phase-active, --file-add)
• Staggered fade-in animations, prefers-reduced-motion respected
• Vary palette each time -- don't repeat the same look

6. Deliver

Open the HTML in the browser and tell the user both paths:

• Plan spec: .maestro/plans/{name}.md
• Visual: ~/.agent/diagrams/{name}-blueprint.html

Next step: if the user accepts the plan and wants to track it as a formal mission, invoke maestro:mission-planning with the plan content as input. The blueprint skill produces artifacts; mission-planning turns them into a tracked mission, then maestro:conduct executes it.

Maestro Conventions

Follow these when generating plans:

• Feature-folder layout: place feature-scoped work under src/features/<name>/ and follow the hexagonal pattern inside it: port -> adapter -> usecase -> command -> test. Plumbing goes in src/infra/, generic utilities in src/shared/. Cross-feature imports must go through @/features/<other> (the feature's index.ts); enforced by bun run check:boundaries
• Conventional commits: reference the commit types in the plan (feat, fix, refactor)
• Version bumps: note if the change requires a minor/patch bump
• Build verification: always include bun run build && ./dist/maestro --version to prove the fresh repo build
• Release verification: for user-facing CLI or TUI work, include bun run release:local && command -v maestro && maestro --version
• TUI changes: include --render-check verification if the change touches TUI
• Binary verification: default examples should use installed maestro; call out ./dist/maestro only when validating the fresh build artifact

Quality Checks

Before delivering:

• Plan spec covers all files that need changing
• Tasks have concrete acceptance criteria (not vague "it works")
• Verification commands are copy-pasteable
• Architecture diagram shows the change, not the entire system
• HTML renders cleanly with no console errors
• Both light and dark themes look intentional
