Field notes for building with agents.

A Claude Code Skill that runs the fallow static analyzer on any JS/TS project: a preflight script checks the setup and reads the limits the project states for itself, a summarizer keeps fallow JSON out of context, and a reference guide covers fixing the fallow config when a finding is noise.

A Claude Code Skill that edits AI-drafted writing back into something a person would actually write. A bundled scanner flags banned words, stock phrases, and punctuation with line numbers, the model handles the structural tells and the rewrite, and a detect-only mode lists the findings without touching the text.

A Claude Code Skill that runs Lighthouse against a URL on mobile and desktop, traces every finding to the real source code of the project, and writes a prioritized, file-and-line fix plan instead of generic advice. Works for any web stack.

A Claude Code skill that turns a messy image-generation request into a repeatable build step: detect the stack, pull the real design tokens, agree on the artifacts and their data source, then scaffold a Playwright and Chromium generator that reads project data so the images stay in sync with the product.

A stripped-down CLAUDE.md that shows the sections worth having — project overview, commands, guiding principles, architecture, standards, and known failure modes — without the project-specific noise.
