slipstream is a Claude Code plugin. You install it into Claude Code in VS Code and it makes Claude work through precise tools instead of whole-file reads, keeps context alive across compaction, ships a guardrailed skill library for production sites on Cloudflare, Supabase, Vercel and Resend, and stands up a live local dashboard so you can watch the agents work.

It is not a CLI you run as a product. There is a small helper binary the plugin calls from its hooks, its slash commands and a bundled MCP server, but you never invoke it directly.

What you feel on day one

1. Claude works through precise tools. A bundled MCP server exposes sp_map, sp_symbol, sp_lines and sp_search, so Claude pulls one declaration instead of opening the whole file. See MCP tools and Token efficiency.
2. Memory builds itself, and you can search it. Every turn is captured as a compact observation and made semantically searchable through a three-layer search (sp_search_memory → sp_timeline → sp_observations), so past work is recoverable without anyone writing it down. See Observation memory and semantic search.
3. Context survives compaction. A PreCompact hook writes a structured digest before Claude Code trims the conversation; the next session reloads it. See Lossless compaction.
4. You watch the agents in a dashboard. Session start boots a 127.0.0.1 server and prints the URL into chat; a Memory search panel queries your project's observations. See Live agent dashboard.
5. You see the budget in the statusline. cp | ctx 12% ok | mem 4 | obs 37 | skill scoped-read. See Statusline.
