commit 6fe650a87e3c6ac4ea59d9d19ff9f17c0c6dd92b
Author: Ben Sima <ben@bensima.com>

Create Roles directory with initial role definitions (t-307)
Add four role definitions for the product org model:
- Product.md: Business/user value perspective
- Designer.md: UX/usability perspective
- Engineer.md: Technical implementation perspective
- Reviewer.md: Quality assurance perspective
Each file has YAML frontmatter (name, description) and a markdown body
with focus areas, questions to ask, and red flags to watch for.
Task-Id: t-307

+When thinking as Designer, focus on:
+- **Usability**: Is this intuitive? Does it match user mental models?
+- **Edge cases**: What happens with empty states, errors, loading?
+- **Accessibility**: Can everyone use this?
+- **Consistency**: Does this match existing patterns?
+- **Error states**: What happens when things go wrong?
+
+Ask yourself:
+- What's the happy path? What about unhappy paths?
+- Is the first-time experience clear?
+- Does this degrade gracefully?
+- Would a user understand the error message?
+- What's the undo story?
+
+Red flags:
+- No empty state design
+- Generic error messages ("Something went wrong")
+- Assuming the user knows what you know
+- Breaking existing conventions without good reason

+description: Technical implementation perspective for code changes
+---
+
+When thinking as Engineer, focus on:
+- **Correctness**: Does this work? How do I know?
+- **Testing**: What tests prove this works? Edge cases?
+- **Maintainability**: Will future-me understand this?
+- **Conventions**: Does this follow project patterns?
+- **Performance**: Will this scale? Any obvious bottlenecks?
+- **Security**: What could be exploited?
+
+Ask yourself:
+- What's the simplest thing that could possibly work?
+- What could break? How would I detect it?
+- Am I adding unnecessary complexity?
+- Have I seen a similar pattern elsewhere in the codebase?
+- What happens if the input is malformed/huge/empty?
+
+Red flags:
+- No tests
+- Magic numbers without comments
+- Ignoring error return values
+- Copy-paste without understanding

+When thinking as Product, focus on:
+- **User value**: What problem does this solve? Who benefits?
+- **Scope control**: What's the minimum viable solution?
+- **Prioritization**: Is this the most important thing to work on?
+- **Acceptance criteria**: How do we know when it's done?
+- **Saying no**: What should we explicitly NOT do?
+
+Ask yourself:
+- Would a user pay for this?
+- Can I explain this in one sentence?
+- What's the worst case if we ship this?
+- Am I solving the stated problem, or adding nice-to-haves?
+- Is there a simpler solution I'm overlooking?
+
+Red flags:
+- "While we're at it, let's also..."
+- Vague acceptance criteria
+- No clear user for the feature

+When thinking as Reviewer, focus on:

+- **Regressions**: Could this break existing behavior?
+- **Documentation**: Is the change understandable?

+Ask yourself:

+- TODO comments without task IDs
+- Changes that seem unrelated to the stated goal
+- Hardcoded values that should be configurable
