What is julie-plugin CLAUDE.md?

Instructions for packaging Julie, a Rust-based code-intelligence server that connects to coding assistants through MCP. The repository contains the plugin package and prebuilt programs, not Julie’s source code.

Maintaining the Claude Code plugin, its launcher, platform binaries, manifests, and bundled skills.

They clarify where packaging changes belong and how to update the bundled programs and skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01241	$0.01241
Opus 5	$0.00620	$0.00620
Sonnet 5	$0.00248	$0.00248
Haiku 4.5	$0.00124	$0.00124

Security

Grade A, and why

julie-plugin 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 7d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Is

This is the plugin distribution repo for Julie, a Rust-based code intelligence MCP server. This repo does not contain Julie's source code. It packages pre-built binaries and skills for installation as a Claude Code plugin.

The actual Julie server source lives at anortham/julie. Changes to server behavior, MCP tools, or language support happen there, not here.

Architecture

.claude-plugin/        Plugin manifest and marketplace metadata
  plugin.json          MCP server definition (command: node hooks/run.cjs)
  marketplace.json     Registry entry for /plugin marketplace
bin/
  archives/            Compressed platform binaries (committed via LFS-like workflow)
hooks/
  run.cjs              Node.js launcher: platform detection, extraction, and exec
  hooks.json           Empty hook registration; behavior hooks are intentionally not shipped
skills/                4 SKILL.md files copied from anortham/julie during updates
package.json           Plugin identity and version

Key Design Decisions

No build step. Binaries ship as compressed archives in bin/archives/. run.cjs extracts on first use and re-extracts when the archive is newer (plugin updated).
Cross-platform via Node.js. run.cjs handles platform detection, archive extraction, and binary exec entirely in Node (which Claude Code guarantees). On Windows, it uses the system bsdtar (%SystemRoot%\System32\tar.exe) for zip extraction to avoid MSYS2/Git Bash's GNU tar which can't handle zip. Launcher scripts must use LF line endings (enforced via .gitattributes).
No behavior hooks. The plugin intentionally avoids SessionStart/PreToolUse/PostToolUse coaching hooks. Julie's MCP server and skills are the stable integration surface; hook-driven nudges caused too much per-client config drift.
Skills are copied, not authored here. The update-binaries.yml workflow clones the julie source repo at a given tag and copies skills/ wholesale. Edit skills in anortham/julie, not here.
Extracted binaries are gitignored. Only the archives in bin/archives/ are tracked. Platform-specific extraction dirs (bin/aarch64-apple-darwin/, etc.) are in .gitignore.

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.

julie-plugin CLAUDE.md is an instructions file published in the GitHub repository anortham/julie-plugin (2 stars, last pushed 18d ago), licensed MIT. It adds 1,241 tokens to every session, about $0.0062 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
