Appendix H: Quick-reference cards
Status: drafted · Time: 2 min · Audience: everyone Outcome: Find printable reference cards that support the safety and workflow chapters.
What this is. Printable one-page cards for the rules and recipes people need near the moment of action. Seven cards covering safety, the foundational tools (terminal, Git, Claude Code), testing (Playwright), the wiki shape, and the Day-1 quick reference that gets new builders unstuck.
| Card | Use it when |
|---|---|
| H.1 — Never put this in a prompt | You are about to paste, upload, connect, or summarise anything that may contain sensitive data. |
| H.2 — Terminal essentials | You are new to the terminal and need the twelve commands and four shortcuts that cover White Belt. |
| H.3 — Git essentials | You are working with Git day to day and need the everyday commands plus the four recovery moves. |
| H.4 — Claude Code essentials | You are using Claude Code daily and want a reference for the permission system, slash commands, and the daily rhythm. |
| H.5 — Playwright essentials | You are writing or debugging Playwright end-to-end tests. |
| H.6 — Minimum viable wiki one-pager | You are setting up a project’s knowledge base and want the four-file shape with the discipline. |
| H.7 — Day-1 quick reference | You are a new builder and want one printable page with install commands, channels, people, and common failures. The page to pin on Day 1. |
The bar for this appendix is high. A card belongs here only if it is useful on a desk, in a workshop, or beside a live workflow.
Maintenance
Section titled “Maintenance”Cards are reviewed quarterly. Terminal commands change less than Claude Code commands; Claude Code commands change less than Playwright; Playwright changes less than the program’s specific tools. Each card is dated; when a card’s content drifts past what the chapter says, the card gets a revision.
To suggest a new card or a revision, open a PR. Reviews happen at the same cadence as the Council’s annual charter revision plus on-demand for time-critical fixes.
