Claude Code First

An evidence-based specification of how to run a software project in which Claude Code is the primary author of the code and a person governs what is built. Each rule rests on graded findings from five projects run this way, and each finding on pointers into their pinned sources, which a gate checks on every push.

  1. Rule pages print literal asterisks around every normative sentence that holds an italic term

    Rule pages render a bold normative sentence holding an italic term as strong with em inside, and a test fails on any rule page that prints two asterisks.

  2. The site header links neither alegauss.github.io nor the GitHub repository, unlike every other alegauss site

    Every page's header carries the "part of alegauss" chip to alegauss.github.io and a GitHub button to the repository, and a test fails on a header without either.

  3. markdownlint lints the governed docs/DEFERRED.md, and fails on a blank line roadkeep wrote there

    markdownlint now ignores docs/DEFERRED.md beside the other four governed files, and its gate passes with the file as roadkeep wrote it.

  4. The guide and specification pages carry their own 892-line stylesheet, outside the design system

    The guide and spec pages take fonts, tokens and site.css at 2026.3.22, re-keyed to the mark's rose, with analytics behind consent; style.css keeps only this site's own blocks.

  5. The site shows no mark of its own: no favicon, no logo in the header, no social card

    Every built page links icon.svg and carries og:image, the guide header shows the mark, and a stdlib-drawn og.png renders the mark and title.

  6. the files-over-APIs open question names what would settle it, and nothing has been measured against it

    F410 grades Shio's SH1141 at R1/S3: files cost 1.29x less and the agent writes 3.1x less; AP's open question and the guide say so, and corpus.md now lists a commit cited past a pin.

  7. the method admits no evidence of what a project's own sessions cost, so the session-budget question cannot be settled

    method.md admits session-cost aggregates on four conditions, harness.md records H16-H20 and O4, and evidence/sessions holds a cost per task for all five projects.

  8. the guide's lessons say nothing about what an agent-facing surface costs, and the page types its lesson count

    The guide's ninth lesson shapes the agent's path to the task and measures it, linking F409, F8, AP-5 and AP-6, and its lesson count is computed from the cards.
