Base

basemode, whose command line tool is called base, is a shared memory layer for coding agents that places the right context in front of an agent at the moment it works, without the agent having to search or make a tool call. It holds a team's rules, decisions, notes and a map of the codebase in a graph, and injects the relevant parts at four points in each agent turn: session start, the prompt, before a tool runs and after it returns. It is built for developers and engineering teams using agents such as Claude Code who are tired of agents relearning the same things. Rules are added from the command line and belong to domains, named subjects with keyword and file path triggers that decide when those rules apply, and each rule can carry a rationale. Registering a project and syncing its code map records every function, class, import and call relationship, so before a file is touched the agent sees what it contains and what depends on it. Only what is relevant arrives: opening a billing file brings the billing rules, not the auth notes. On team plans the graph is shared, so a decision recorded by one developer reaches a colleague's agent almost immediately, with scoped read and write access per team or repository, and every admin action is available through an API. Pricing is per user. Free costs $0 for solo work and open source, with one graph capped in size. Team is $19 per user per month for up to 50 users and is self serve. Business is $35 per user per month and adds single sign on, access control, an audit log and annual terms. Reads are never counted. The installer currently wires only Claude Code; the data is host independent, but Codex and Antigravity are not configured automatically.
