livestore: Instructions file for Claude Code

CLAUDE.md

livestore CLAUDE.md is an instructions file for Claude Code from livestorejs/livestore. It costs 1,552 tokens per session, scanned A, original, Apache-2.0.

A project-specific instruction file for the LiveStore TypeScript repository. It explains how to install dependencies, choose between minimal and full setup, and use the repository's design notes as a source of truth.

In plain words
What is it for?
Use it when changing LiveStore code, tests, documentation, generated sources, releases, or infrastructure so the agent follows the repository's setup and checking rules.
Why use it?
It gives a coding agent the project's required tools, commands, and validation boundaries instead of relying on generic setup assumptions.

Instructions file for Claude Code

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

This is livestorejs/livestore's own configuration. It tells Claude Code how to work on livestore 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 livestore configures →

About the project

LiveStore is a state-management framework that stores application data in SQLite, a database embedded in the application, and synchronizes that data through a built-in engine. It is intended for applications that keep data locally while supporting reactive updates and synchronization.

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

livestore 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 4d 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-Specific Instructions for Claude

Setup

Minimal Setup

For ordinary TypeScript, core unit-test, Vite, local Wrangler, and docs-check work, provide Node.js 24, Bun, and the exact pnpm version declared by package.json#packageManager, then run:

./scripts/bootstrap-minimal.sh

The script verifies prerequisites and performs a frozen install; it never installs tools globally. Bun 1.3.13 is the known-good Docker realization. The optional root compose.yaml supplies that toolchain in an exclusive bind-mounted checkout.

Full Setup (Nix + devenv)

Run devenv shell for Playwright and full docs builds, generated-source or wa-sqlite changes, release and infrastructure work, or repository-wide parity. Before final handoff, escalate to this lane whenever the relevant validation extends beyond the finite Minimal Setup checks; setup success never substitutes for the full required CI bar. The authoritative boundary is context/03-delivery/01-composition/01-developer-environment/spec.md.

Intent Layer (context/)

context/ is the project's intent layer (a VRS tree) — the always-current source of truth for the system's design: vision, requirements, subsystem contracts (spec.md), ontology, decisions, and tracked drift. Read context/spec.md for its structure and conventions (branch layout, ID scheme, maturity markers, enforcement).

  • When you change system behavior or a contract, update the owning context/ node. The docs site (docs/) derives from the intent layer and must not contradict it; context/ontology.md is the canonical source for terms.
  • Consequential choices → the node's .decisions/; confirmed divergence between intent and code → its .delta/; open design questions → open-questions.md. New/unaccepted proposals live in contributor-docs/rfcs/, not in spec bodies — they fold into the owning nodes on acceptance.
  • vision.md and requirements.md are protected — confirm with a maintainer before editing them; specs, decisions, deltas, and open questions evolve freely.
  • A Vitest suite (tests/package-common/src/intent-layer/) checks the tree's mechanical invariants (ID uniqueness, refines: resolution, links, decision shape, …); run it and keep it green when editing context/.

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.
