Write a Technical Specification

Write a technical specification for [FEATURE OR SYSTEM].

Context:
- What is being built: [DESCRIPTION]
- Who will read this: [ENGINEERS / DESIGNERS / PRODUCT TEAM / ALL]
- Complexity level: [SIMPLE FEATURE / COMPLEX SYSTEM / INTEGRATION]

Technical spec should include:
1. Overview — what this is and why it is being built
2. Goals and non-goals — what is in scope and what is explicitly out of scope
3. User stories — who uses this and what they need to accomplish
4. Functional requirements — what the system must do (numbered list)
5. Technical design — how it will be built (architecture, data models, APIs)
6. Edge cases and error handling
7. Security considerations
8. Performance requirements (if applicable)
9. Testing plan — how this will be verified
10. Open questions — things still to be decided

Keep it precise and scannable. Engineers should be able to build from this.
