Building systems.
Cultivating understanding.
I’m J, a software engineer exploring AI agents, reliable systems, and the ideas that connect them. This is my open notebook — part engineering laboratory, part digital garden.
01 / From the laboratory
All projectsAI Development Engine
A foundation for planning, executing, and reviewing bounded software-engineering agent tasks.
Repository Intelligence System
Turn source code, dependencies, and change history into evidence for engineering decisions.
Knowledge Platform
Retrieval and connected knowledge with source-level provenance.
02 / Growing in the garden
All notesA note is an invitation to connect
Why useful knowledge systems need provenance and relationships before they need embeddings.
Agents need boundaries, not just better prompts
A working note on giving coding agents explicit authority, budgets, and a definition of done.
Designing systems you can replay
Deterministic inputs make failures easier to investigate, but external effects still need boundaries.
03 / On the record
All writingA small, static foundation
Why this garden starts with files, explicit links, and a build you can understand.
