Six of these have a case study behind them, written the same way each time: the problem, the constraint, the decision I made and why, and the part that broke. The rest are here because they’re real, not because they’re finished.
No case study on these. They’re listed because leaving them off would make the six above look luckier than they were.
Obsidian plugin
A vault curator with no ability to write. The agent decides where a file belongs; the plugin validates every field of that decision against the real vault and performs the write itself.
Agent system · media pipeline
A five-stage disc-to-library pipeline where exactly one stage may write to the protected drive, it never runs unattended, and cleanup is gated on the copy being independently re-verified first.
Native application · Swift
A three-tab desktop client built on one idea: an agent is its file. A markdown definition becomes a real CLI invocation, and the permission gates named in that file are enforced by the runtime rather than trusted to the prose.
Web · desktop · iOS
The first assistant build, and the one that taught the most. A fixed planner model decides what to do while a chosen model writes the reply, and context is split into four domains with different rules about what may be summarised away.
Web application · label
The label site: a catalog of artists, releases and tracks with the rights and credit data modelled properly underneath, so a release page and a registration never disagree about who did what.
Native utility · Swift
A batch media tagger with a pre-flight console that validates external volume state before it moves a single file. Also the honest counterexample here: 5,426 of its lines live in one view file.
Venture · behavioral health education
A behavioral health education company — explicitly not a clinical provider — built on a model written out of first-hand experience. Three products: an application, a book, and a course.
Agent architecture
Ten agents that each own an outcome rather than a task, and delegate strictly across the seams. One of them is labelled STUB in its own definition, because it has no data source yet and saying so is cheaper than finding out later.
