## Brand context
the future of building happens together

GitHub is a complete developer platform for developers, teams, and enterprises to collaborate on code and build, scale, and deliver secure software in one place, bringing developers, agents, and code together across the software development lifecycle. Its differentiator is the unified platform approach that combines developer workflows with AI code creation and enterprise security capabilities such as GitHub Copilot, GitHub Enterprise, and GitHub Advanced Security in a single offering.

Audiences:
- enterprise software engineering teams and platform engineering orgs
- startups and small-to-medium software teams
- open source maintainers and nonprofit engineering communities

## Evidence coverage (private beta)
screens indexed:       31
screens VLM-annotated: 31
workflows mapped:      3
workflows annotated:   3
platforms:             Web

Evidence returned by the MCP is deduplicated, ranked for the request, and linked to source and permission provenance. Counts reflect the canonical evidence-store snapshot, not invented adoption or asset totals. Screen imagery is delivered through authenticated, metered MCP calls; it is not distributed on public pages.

## Retrieval
Ask the design.live MCP for the project brief, constraints, and desired GitHub qualities. It returns ranked evidence and an agent-ready implementation plan; do not copy a source screen wholesale.
