Starting from a lab spec about city emergency coordination, we designed a UML class diagram in draw.io, mapped it to a SQLite schema, and built a working menu-driven CLI that demonstrates incident reporting, unit dispatch, and the availability guard.
A slow, deliberate walkthrough of four graduate DS/ML exercises β vectorized confusion matrices, Python descriptors, context managers, and lazy generator pipelines β with the emphasis on understanding over completion.
A session spent red-teaming a set of Python security utilities β finding bypass vectors in sensitive field masking, then implementing hardened replacements with 62 passing tests.
A Ralph Docker session ran overnight with unlimited iterations, creating 67 empty workspace branches and consuming 71% of my weekly Sonnet token allotment β with zero productive output. Here's the forensic analysis and the fix.
Ralph-docker now has a built-in setup command that interviews you and generates all project files via Claude β no external skill required. Plus, a rewrite of the README to put observability front and center.

A session where Claude Code reviewed four open PRs on a Go/RabbitMQ event system, identified bugs ranging from mutex contention to JSON schema mismatches, and fixed them all β merging three and leaving one ready to go.
Building a multi-agent system incrementally across 4 assignments β agent loops, pluggable tools, bounded memory with escalation, and orchestration β all in pure Python with 50 tests and zero LLM dependencies.
