jumpstarter: Instructions file for Claude Code

CLAUDE.md

jumpstarter CLAUDE.md is an instructions file for Claude Code from jumpstarter-dev/jumpstarter. It costs 725 tokens per session, scanned A, original, Apache-2.0.

Instructions for Claude Code when working on the Jumpstarter project. They point the agent to project rules for structure, driver creation, operator releases, and enhancement proposals.

In plain words
What is it for?
Finding the right Jumpstarter rules before making changes, especially when modifying project structure, creating drivers, releasing the operator, or proposing a project enhancement.
Why use it?
They give the coding agent the project-specific context needed to place changes correctly and follow local development processes.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is jumpstarter-dev/jumpstarter's own configuration. It tells Claude Code how to work on jumpstarter 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 jumpstarter 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

jumpstarter CLAUDE.md 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 28d 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.

Project Rules and Guidelines

Important project-specific rules and guidelines are located in the .claude/rules directory:

  • .claude/rules/project-structure.md: Understanding the monorepo structure, workspace configuration, package organization, and development workflows. Read this to understand how the project is organized and where files should be located.

  • .claude/rules/creating-new-drivers.md: Guidelines for creating new driver packages, including naming conventions, required information, and the driver creation process. Read this when tasked with creating or modifying drivers.

  • .claude/rules/releasing-operator.md: Step-by-step guide for releasing a new version of the Jumpstarter operator, including which files to update, image tag conventions, bundle generation, and community-operators contribution workflow.

  • .claude/rules/jep-process.md: Process for creating Jumpstarter Enhancement Proposals (JEPs), including when to use them, numbering conventions, required sections, and the design decision format. Read this when proposing or reviewing cross-cutting changes or features that require community consensus.

  • .claude/rules/demo-recording.md: Conventions behind the asciicast demo on the documentation landing page: pacing and readability, how the narration is written, theme-safe colours, keeping personal paths and credentials out of the recording, and lease naming. Read this when changing demo/, the recording, or how it is played back.

  • .claude/rules/e2e-doc-sync.md: Rules for keeping e2e/README.md aligned with E2E tests, runners, and CI labels (mirrors .cursor/rules/e2e-doc-sync.mdc). Read this when changing E2E behavior or E2E documentation.

When to Read These Rules

  • Always: Read project-structure.md when working with files, packages, or understanding the codebase layout
  • When creating drivers: Read creating-new-drivers.md before creating, improving, or documenting driver packages
  • When releasing the operator: Read releasing-operator.md before preparing a new operator version for OLM
  • When creating JEPs: Read jep-process.md before proposing enhancements that affect multiple components, change public APIs, or require community discussion
  • When touching the demo recording: Read demo-recording.md before changing anything under demo/, re-recording docs/source/_static/demo.cast, or adjusting how the landing page plays it
  • When modifying E2E tests or E2E docs: Read e2e-doc-sync.md and keep e2e/README.md synchronized in the same PR
  • When modifying structure: Consult both files when making changes that affect project organization

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.
