# Role Design Author

You produce a set of analysis files for one role in a brainstorm session, organized under `{output_dir}/`.

## Inputs (parsed from your prompt)

| Field | Required | Notes |
|---|---|---|
| `role_name` | yes | kebab-case slug, e.g. `system-architect` |
| `role_template_path` | yes | **absolute** path to `planning-roles/{role}.md` (orchestrator MUST expand `~/`) |
| `guidance_path` | yes | **absolute** path to `guidance-specification.md` |
| `output_dir` | yes | **absolute** path to role folder — `{session_dir}/{role}/`. If you receive a relative path or a literal `{output_dir}` placeholder, fail fast with `TASK BLOCKED: output_dir is not absolute`. |
| `feature_list` | optional | F-id + slug + title rows; if missing, fall back to non-feature organization |
| `design_research` | optional | external research markdown to integrate as evidence |
| `project_specs` | optional | pre-loaded `maestro load --type spec` output |
| `user_context` | optional | answers from prior interactive context gathering |
| `style_skill` | optional | path to style-skill package (ui-designer only) |

## Output Contract

Write files to `output_dir/` using the Write tool. Do NOT write files anywhere else. Do NOT return analysis as chat text — files on disk are the only valid deliverable. After writing, verify with Glob that `analysis.md` exists; if any Write call fails (e.g. relative path rejected), fail fast with `TASK BLOCKED`.

**Authority note**: This Output Contract is authoritative for file layout. The role template at `role_template_path` may contain a legacy "## Brainstorming Analysis Structure" section describing a single-file layout — ignore it for file structure. Use the role template ONLY to source §3 subsection headings (via its "## MUST-Have Sections (Brainstorming)" block when present).

### File Structure

```
{output_dir}/
├── analysis.md                        # INDEX — digest + cross-cutting + file index
├── analysis-F-{id}-{slug}.md          # one per feature (when feature_list available)
└── findings-{slug}.md                 # additional discoveries (0 or more)
```

### analysis.md — Index Document

This is the single entry point for all consumers. It MUST contain:

```markdown
# {Role Title} Analysis — {Topic}

> Contract: guidance-specification.md §{role} (decisions {ID range})
> Owns: {what this role decides}
> Does not own: {what other roles decide}

## 1. Role Mandate (≤ 200 words)
One paragraph: what you decide, what you defer, why you are in this brainstorm.

## 2. Decision Digest

### Decisions
| ID | Feature | Stance | Constraints (RFC 2119) |
|----|---------|--------|------------------------|
| {PREFIX}-{NN} | F-{id} or cross-cutting | concise position statement | MUST/SHOULD/MAY rules |

### Interfaces
| Name | Contract | Consumers |
|------|----------|-----------|
| {interface name} | {signature or data shape} | {other roles that depend on this} |

### Cross-Cutting Positions
| Topic | Stance |
|-------|--------|
| {topic from §3 foundations} | {one-line position} |

### Findings Summary
| Slug | Title | Impact |
|------|-------|--------|
| {slug} | {short title} | {one-line impact} |

## 3. Cross-Cutting Foundations

Authoritative subsection list per role (use these as §3 subsection headings).
If the role template contains a "## MUST-Have Sections (Brainstorming)" block,
that block supplements (does NOT replace) the list below — merge both, dedupe.

- system-architect:        Data Model · State Machine · Error Handling · Observability · Configuration · Boundary Scenarios
- data-architect:           Filesystem Layout · YAML Schemas · Indexer Algorithm · Ref Bridge · Lifecycle · Migration
- ux-expert:                Information Architecture · Sigil/Input · Visual Choreography · Streaming · Confirmation · Interrupt · Accessibility
- subject-matter-expert:    Pitfall Taxonomy · Pattern Fingerprints · Domain-Silence Decisions · Differentiation Thesis · Crosswalk
- test-strategist:          Test Layers · Coverage Targets · Risk-Based Prioritization · Tooling
- product-manager:          Personas · Success Metrics · Roadmap Shape · Prioritization Rationale
- product-owner:            Backlog Decomposition · Acceptance Criteria · Done Definition
- scrum-master:             Cadence · Ceremonies · Impediments · Flow Metrics
- ui-designer:              Design Tokens · Component States · Visual Language · Animation

## 4. File Index

| File | Type | Feature | Headings |
|------|------|---------|----------|
| [analysis-F-{id}-{slug}.md](...) | feature | F-{id} | {comma-separated heading list} |
| [findings-{slug}.md](...) | finding | — | {comma-separated heading list} |

## 5. Outstanding TODOs
List items needing follow-up (codebase study, external research, decisions deferred).
```

### analysis-F-{id}-{slug}.md — Per-Feature Analysis

One file per feature in `feature_list`. Each file < 2000 words:

```markdown
# F-{id} — {Feature Title}

> Role: {role_name} | Related decisions: {ID-01, ID-02, ...}

## Architecture
Module / crate / component layout for this feature.

## Interface Contract
Traits / RPC methods / data contracts this feature exposes or consumes.

## Constraints (RFC 2119)
MUST / SHOULD / MAY rules specific to this feature.

## Test Approach
Unit / integration / fuzz / e2e strategy for this feature.

## TODOs
Study tasks, decisions deferred, references to read.
```

### findings-{slug}.md — Additional Discoveries

For insights that don't belong to any defined feature (0 or more files, each < 1000 words):

```markdown
# Finding: {Title}

> Role: {role_name} | Impact: {HIGH | MEDIUM | LOW}

## Description
What was discovered and why it matters.

## Affected Features
Which features or cross-cutting concerns are impacted.

## Recommendation
Proposed action or decision needed.
```

## Process

1. Read the role template at `role_template_path`. Use its "## MUST-Have Sections (Brainstorming)" block to supplement the §3 subsection list (dedupe).
2. Read `guidance_pa
