cassini-workshop: Command for Claude Code

.claude/commands/init.md

init is a command for Claude Code from robconery/cassini-workshop. It costs 18 tokens per session (731 once invoked), scanned A, a copy of init, MIT.

A project setup command that creates starter files such as CLAUDE.md, a README, a .gitignore file, and a docs folder. These files contain headings and placeholders rather than invented project decisions.

In plain words
What is it for?
Use it at the start of a project to create documentation and configuration stubs for later exploration, design, and planning.
Why use it?
It gives a new project a consistent working structure without overwriting files that already exist.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is robconery/cassini-workshop's own configuration. It tells Claude Code how to work on cassini-workshop itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cassini-workshop configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to init — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

init

Stand up the working files for a project so the later phase commands have something to fill. You create structure, not content — stubs with headings and TODOs, never invented decisions.

## Rules

- DO NOT REPORT SOMETHING IS FIXED IF YOU HAVEN'T COMPILED THE APP
- DO NOT SEARCH node_modules for answers. GO ONLINE.
- Use emoji for markdown documents for readability.
- Get to the point, be terse, do not over explain. Tokens are water, we're in the desert. Use emoji instead of prose if you can.
- Never install a package by editing the manifest, always use a package install tool, such as `npm install`, `bun install`, etc.

Scope

  • IN: create CLAUDE.md, the docs/ skeleton, a README stub, .gitignore.
  • OUT: deciding what the project is (that is /explore), architecture (/design), tasks (/plan). This command does not interview the problem.

Preflight

  1. Re-entrant: if a file already exists, leave it alone. Report what was already there vs. what you created. Never clobber.
  2. Detect the ground:
    • Code already present → seed CLAUDE.md from what's actually there (language, test command, run command, layout). Be factual, no guessing.
    • Empty dir → CLAUDE.md gets a stub with those headings and TODO.

Produce

  • CLAUDE.md (root, owned here) — the how: stack, conventions, test & run commands, the phase commands available (/explore, /design, /plan, /document), and the rule that each doc has one owner.
  • docs/PROJECT.md — stub, owned by /explore. Headings: Problem, Who it's for, Goals, Scope (in/out), Open questions.
  • docs/ARCHITECTURE.md — stub, owned by /design.
  • docs/SPEC.md — stub, owned by /design.
  • docs/STORIES.md — stub, owned by /plan.
  • docs/PLAN.md — stub, owned by /plan. Empty checklist.
  • docs/MEMORY.md — the project decision log: decisions made with AI, preserved for Claude Code. Header + an empty dated-entry list. Curated by /document; appended to by every phase command. Distinct from the ~/.claude memory system.
  • README.md — one-line stub, owned by /document.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
