+Project goal is to make a local codebase knowledge management system to assist pair-coding model agent understanding codebase
+### Designed features
+- Lazy load, only generate abstract(knowledge) for files/directories that are required by a model
+- Knowledge access:
+  - more like a cache, don't let the model query knowledge by semantic directly, instead, provide list of topics as hot spots first
+  - if hot topics didn't hit, list the root dir of code base, let model determine which file to analysis or directory to further investigate
+  - the analysis of file is also done by a model, whom may also request knowledge of another file to understand the current one
+  - some machinism needed to prevent circular dependency(e.g. require file A to understand file B, and require file B to understand file A)
+- Codebase access:
+  - service connects to a workspace that contains the codebase via a ssh session
