Practical AI, without the noise.

Make better decisions about agents, models, and automation. Start with a real workflow, define a useful result, and learn how to check it.

Field guides

Firsthand experience. Measured results. Primary sources.

  1. Workflow performance

    Less memory pressure. Measured Rust vs. Python results.

    How I reduced AI agent memory pressure with Typst, Rust, and streaming CSV workflows. Compare measured runtime and peak memory in a million-row benchmark.

  2. Agent reliability

    Your AI agent said “done.” Prove it.

    Define agent completion with independent evidence, a worked intake example, and a reusable scorecard for outcomes, destinations, and side effects.

  4. Decision models

    Decision models vs. LLMs.

    Choose rules, a bounded decision model, a general LLM, or human review for each workflow step. Includes an illustrative triage example and a selection worksheet.
