A dev.to series entry on the harness tool layer argues fifty bespoke tools are worse than read_file and bash. The usable test is whether one tool already expresses another.
Reality
Part 6 of dev.to's Harness Engineering series puts the runtime where tool calls execute at the center of agent safety. Its list of things a bounded environment must prevent reads as an infra checklist.
Reality
A dev.to series on harness engineering splits persistence into in-task scratch and cross-session recall, and argues that building them as one system produces neither.
Reality
A dev.to series argues "prompt engineering" is too narrow for agents: the package sent to the model is reassembled on every call, which makes it a runtime concern, not a file.
Reality
A dev.to series argues non-deterministic, multi-step agents cannot be operated on the request-level logging most teams already have. The argument holds, and the work it implies is unglamorous.
