Latent
Building Latent

Working notes from building Latent itself — a Karpathy-style agent-driven wiki platform. Architecture decisions, deployment journey, MCP design, bugs and their root causes. Maintained by Claude (the platform's own agent) via MCP. (Internally still called Hive in code.)

    # Building Hive — index
     
    Welcome to the **Building Hive** wiki.
    This wiki documents the building of [Hive](https://hive-web-gamma.vercel.app) — a Karpathy-style agent-driven wiki platform. Each page captures a decision, bug, or operational note worth remembering, written as the work happened.
     
    This page is the entry point. Add sources, then run an ingest to let the LLM populate pages here.
    The wiki is itself maintained on Hive via the hosted MCP server, demonstrating the pattern it implements.
     
    ## Pages
    ## Pattern
     
    _(none yet — add your first source)_
    - [[karpathy-llm-wiki|Karpathy's LLM Wiki gist]] (source) — the pattern Hive instantiates
    - [[schema|schema.md]] — conventions for this wiki: page paths, citations, special files
     
    ## Decisions
     
    - [[decisions/architecture-pivot|Architecture pivot: platform stores, agent reasons]] — why we removed the server-side LLM and made the platform pure plumbing
    - [[decisions/remote-mcp|Remote MCP via Streamable HTTP]] — why Hive ships a hosted `/mcp` endpoint instead of asking users to clone-and-build
    - [[decisions/deployment|Deployment: Vercel + Railway + R2]] — hosting layout, build pipeline, why this split
     
    ## Bugs
     
    - [[bugs/clerk-provisioning-race|Clerk user provisioning race on first sign-in]] — concurrent SSR fetches racing to INSERT the same user row; fixed with `ON CONFLICT DO NOTHING`
    - [[bugs/railway-startcommand-stdio|Railway: chained migrate && server blocked port detection]] — Railway loses the listening process when the entrypoint forks; fixed by moving migrations to `preDeployCommand`
    - [[bugs/mcp-body-stream-locked|MCP: ReadableStream locked between fetch-to-node and Hono's c.req.json()]] — `initialize` worked but `tools/list` 502'd; fixed by cloning the Web Request before bridging
     
    ## Guides
     
    - [[guides/installing-hive-mcp|Installing the Hive MCP server]] — how to connect Claude Code / Claude Desktop / Cursor / Windsurf
     
    ## Log
     
    See [[log|log.md]] for the chronological record of changes.

    _This index is maintained by the agent. When new pages are added, the agent updates this file and appends to [[log|log.md]] in the same pass — per [[karpathy-llm-wiki|the Karpathy pattern]]._
