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 | $0.08103 | $0.08103 |
| Opus 5.5 | $0.03241 | $0.03241 |
| Sonnet 5.5 | $0.01621 | $0.01621 |
| Haiku 4.5 | $0.00810 | $0.00810 |
Grade B, and why
julie AGENTS.md scanned grade B with 1 finding 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- **One-time setup**: `cargo build --release && cargo xtask dev-link` — replaces the bundled `julie-server` inside `~/.claude/plugins/cache/julie-plugin/julie/<v>/bin/<arch>/` with a symlink to `target/release/julie-serv Copies of this mod

Julie — 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 39 user-facing language and manifest formats 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: Machine service (Streamable HTTP MCP + JSON API + dashboard) with stdio shim. The no-args
julie-serverserves as a lightweight stdio shim, auto-starting the background service if missing. Service control:julie-server service status|stop|restart. - Origin: Native Rust implementation for true cross-platform compatibility
- Crown Jewels: 39 user-facing language and manifest formats across 42 parser inventory labels, maintained in the external
anortham/julie-extractorsrepo and consumed here as a pinned git dependency
🏆 Current Language Support (39 user-facing formats, 42 parser labels)
The 39 user-facing language and manifest formats map to 42 parser inventory labels. JSX and TSX are aliases; qmldir is a container format, not an additional language. The extractors live upstream in anortham/julie-extractors (consumed as a pinned git dep). Language and parser work — adding languages, upgrading parsers, golden fixtures, capability tests — happens there. Re-pin Julie's julie-extractors git dep in Cargo.toml and sync SEMANTIC_INDEX_ENGINE_VERSION in crates/julie-facts/src/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, F# 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.

julie AGENTS.md is an instructions file published in the GitHub repository anortham/julie (6 stars, last pushed 27d ago), licensed MIT. It adds 8,103 tokens to every session, about $0.0324 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
