Token Usage Is an Input Cost, Not an Engineering Outcome
Counting tokens repeats an old measurement mistake unless AI-assisted work is evaluated through delivery, quality, and user outcomes.
Engineering
Design, construction, verification, operation, and reliability of technical systems.
12 published materials across notes, projects, and publications.
Primary in this field
Work whose central question belongs to Engineering.
Agentic End-to-End Testing Still Needs an Independent Oracle
Slack's agent-driven E2E experiments expose a useful new execution model, but adaptation must remain separate from the authority to declare success.
Playwright Is Mature; Migration Still Needs an Evidence Case
Playwright's mature tooling makes it a strong default for new browser automation, but migration should be decided through a representative experiment.
Property-Based Testing Starts with the Property, Not the Generator
Property-based testing is more than randomized input generation; its value depends on the property, distribution, oracle, shrinking, and evidence.
Introducing MetronForge: An Independent Research Notebook
MetronForge is an independent research notebook for engineering observations, computational experiments, projects, and formal publications.
A Test Strategy Is Risk Allocation, Not a Geometric Shape
Pyramids, trophies, and honeycombs summarize different testing economics; a defensible strategy begins with risks, evidence, and feedback constraints.
Documentation as Code Still Needs Tests for Documentation
Version control and CI improve documentation workflow, but a successful build cannot establish that instructions remain true, complete, or usable.
Architecture Is the Set of Decisions That Constrain Future Change
Pierre Pureur and Kurt Bittner correctly place decisions at the centre of architecture; their importance follows from reversal cost and blast radius.
Cross-field connections
Work centred elsewhere that materially uses or informs Engineering.
Agentic Resource Discovery Still Needs a Verification Boundary
ARD can help agents find capabilities across organizations, but discovery metadata must remain outside the trusted execution boundary.
Choose Agent Infrastructure by the First Constraint That Can Break It
Agent stacks should be selected layer by layer, with explicit contracts for state, tools, memory, evaluation, and recovery.
Selecting Fewer MCP Tools Is Not the Same as Enforcing Least Privilege
GitHub MCP tool filtering reduces context and accidental capability exposure, but real least privilege also requires identity, authorization, and effect controls.
