Four tools called agent memory. Four different approaches to what should survive. One puts decision rationale next to the code.

Four tools called agent memory. Four different approaches to what should survive. One puts decision rationale next to the code.

Rationale, structured knowledge, or codebase intelligence for coding agents?

Keep the Why records why a codebase is the way it is. Decisions can cite decisions in other repositories. The Globe follows those citations outward, one wave at a time, without turning project memory into a centralized service.

Decisions that cite each other across repositories — no graph database, no central index, no account. Just Markdown and Git.

Project memory is not another database for your coding agent. AI exposed the one thing the repository was systematically missing: why.

How a small structural change reduced unnecessary Git conflicts in a shared Markdown index — and made it easier for coding agents to navigate.
