julie: Instructions file for Claude Code

CLAUDE.md

julie CLAUDE.md is an instructions file for Claude Code, Codex from anortham/julie. It costs 8,626 tokens per session, scanned B, a copy of julie AGENTS.md, MIT.

Project instructions for Julie, a Rust server that helps coding tools search, navigate, and edit code across 36 programming languages. It uses language-aware parsing, full-text search, a database, and vector search.

In plain words
What is it for?
Use them when developing Julie, especially its code-intelligence features, language support, MCP server, storage, or search implementation.
Why use it?
They give coding agents the project facts and runtime constraints they need to make compatible changes. They also clarify how the server communicates and is organised.

Instructions file for Claude CodeCodex

Written for Claude Code and Codex: ${CLAUDE_PLUGIN_ROOT} variable, but also reads ~/.codex or $CODEX_HOME. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is anortham/julie's own configuration. It tells Claude Code and Codex how to work on julie 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 julie configures β†’

Runs only inside a plugin β€” its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

Reuse

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 B, and why

julie CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories β€” prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency β€” measured 8d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Julie β€” Development Guidelines

All AI coding agents (Claude Code, Copilot, Cursor, Windsurf, Cody, Gemini CLI, aider, etc.) must follow these guidelines.


Project Overview

Julie is a cross-platform code intelligence server built in Rust. LSP-quality features across 36 languages via tree-sitter, Tantivy full-text search, and instant search availability.

Key Project Facts

  • Language: Rust (native performance, cross-platform)
  • Purpose: Code intelligence MCP server (search, navigation, editing)
  • Architecture: Tantivy full-text search + SQLite structured storage + KNN vector search (embeddings)
  • Mode: Stdio MCP server (JSON-RPC over stdin/stdout). The no-args julie-server serves in-process over rmcp stdio, leader-locked per workspace. There is no forked daemon, stdio adapter, HTTP MCP bridge, or julie daemon runtime.
  • Origin: Native Rust implementation for true cross-platform compatibility
  • Crown Jewels: 36 tree-sitter extractors with comprehensive test suites, now maintained in the external anortham/julie-extractors repo and consumed here as a pinned git dependency

πŸ† Current Language Support (36 - Complete)

The 36 extractors live upstream in anortham/julie-extractors (consumed as a pinned git dep). Language and parser work β€” adding languages, upgrading parsers, golden fixtures, capability tests β€” happens there. Re-pin julie's julie-extractors git-dep in Cargo.toml and sync SEMANTIC_INDEX_ENGINE_VERSION (in src/tools/workspace/indexing/engine_version.rs) to the new tag's EXTRACTION_CONTRACT_VERSION to pick up a new release.

Core Languages: Rust, TypeScript, JavaScript, Python, Java, C#, VB.NET, PHP, Ruby, Swift, Kotlin, Scala Systems Languages: C, C++, Go, Lua, Zig Functional: Elixir, Erlang Specialized: GDScript, Vue, Razor, QML, R, SQL, HTML, CSS, Regex, Bash, PowerShell, Dart Documentation: Markdown, JSON, TOML, YAML, XML

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.
