The Series
Field notes from a daily practice with AI coding agents. Patterns, tools, sharp edges. Evidence-based, no fluff.
Registered Twice: Six Entries for Four Scripts
Two hooks appeared in two separate matcher groups, so both ran twice per prompt. Duplicate registration is invisible until you count entries against distinct scripts.
Filename-Scoped Search: How a Grep Overturned the Wrong Report
A report declared a 519-PNG manifest nonexistent. The manifest existed. The search had been scoped to filenames, and absence of a hit was read as absence of the thing.
The Placeholder That Could Not Match
Five premises arrived as unsubstituted template literals. A gate that halts on `{{PR_HEAD_SHA}}` is not being pedantic — it is refusing to invent a value.
Symmetric Truncation: A Passing Gate With a Broken Method
The verdict survived the correction. The method did not. A regex that ate flag suffixes on both sides of a comparison produced the right answer for the wrong reason.
What we ship
ValidationForge proves that code works. Anneal proves the plan works before any code gets written. Two flagships, both production-grade. The other cards are companion tooling from the series.
