AI workshop: reject stale deployment evidence
Build a deployment decision in three stages: check identity, reject stale observations, and keep the decision independent of sensitive diagnostics.
Intermediate · Codex CLI · Browser exercise
AI workshop: recover an ordered tenant stream
Repair a reconnect reducer that trusts every message. Check snapshot identity, duplicate delivery, sequence gaps, and atomic recovery with eight acceptance tests.
Intermediate · Codex CLI · Browser exercise
AI workshop: review a logging change for data exposure
Review a short request-event function, identify how new fields can leak into logs, and verify a deliberate output contract with regression tests.
Intermediate · Codex CLI · Browser exercise
AI workshop: fix a priority bug without changing the input
Use a small failing test suite to separate numeric ordering, stable ties, and input ownership before asking a coding agent for a patch.
Beginner · Codex CLI · Browser exercise
AI workshop: design retry tests before fixing the parser
Turn retry timing into a table of deterministic cases, inject the clock, and use failures to review an AI-generated implementation.
Intermediate · Codex CLI · Browser exercise
AI workshop: automate a reproducible release manifest
Build a deterministic artifact manifest, validate its inputs, and use byte-for-byte checks to evaluate an AI-assisted automation change.
