start

Use to open the SDD visual dashboard — the local read-only browser UI that shows every feature's pipeline stage, renders its artifacts (markdown, mermaid C4/sequence/ER, OpenAPI as plain YAML), and drives the pipeline by sending /sdd:<skill> commands back into this live session. Triggers on "start the dashboard", "open the SDD dashboard", "sdd dashboard", "/sdd:start", "show the pipeline UI", "відкрий дашборд", "запусти панель SDD". The sdd-dashboard MCP server auto-starts at session open (via .mcp.json), resolves the project from CLAUDE_PROJECT_DIR, binds its loopback HTTP listener, and writes the dashboard URL (with a per-session capability token) to ~/.claude/sdd-dashboard/current.url — so start's job is simply to READ that file and print the URL. No MCP tool call, no channel round-trip on the common path. Opt-in: requires dashboard_enabled: true in .claude/sdd.local.md and Bun installed; if either is missing it prints guidance and exits cleanly (pure-markdown skills are unaffected).
