Ask HN: Are you building an AI company brain?

A user asks Hacker News for advice on building an "AI company brain" at their CTO's request, describing a plan with an LLM wiki for slow-moving data, direct retrieval of fast-moving data via shared skills, employee access through a coding agent or chat interface over MCP, and a 24x7 agent owning the wiki and skills repo. They raise doubts about the 24x7 agent's cost, concurrent edits, what kind of agent to use, whether an agent is needed at all, and whether they are over- or under-complicating the design.
