Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00725	$0.00725
Opus 5	$0.00362	$0.00362
Sonnet 5	$0.00145	$0.00145
Haiku 4.5	$0.00072	$0.00072

Security

Grade B, and why

hurlicane CLAUDE.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 today.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Claude Orchestrator

Setup

When asked to set up or install this project, run the following steps in order. Check each prerequisite and install if missing, then install npm dependencies.

1. Check Node.js (requires ≥ 22)

node --version

If not installed or too old, install via nvm or directly from nodejs.org:

# macOS with Homebrew
brew install node

2. Check tmux

which tmux || echo "MISSING: tmux not found"

Install if missing:

# macOS
brew install tmux
# Ubuntu/Debian
sudo apt install tmux

3. Check C++ build tools (required for node-pty)

# macOS
xcode-select -p || xcode-select --install
# Ubuntu/Debian
which make || sudo apt install build-essential python3

4. Check Claude Code CLI

which claude || echo "MISSING: claude not found"

Install if missing:

npm install -g @anthropic-ai/claude-code

5. Install npm dependencies

npm install

6. Verify setup

node --version   # should be ≥ 22
which tmux
which claude
ls node_modules | head -5

If everything looks good, start the server with:

npm run dev

Then open http://localhost:3000.

Dev Commands

npm run dev — start server (port 3000) + Vite dev server concurrently, both with hot reload
npm run build — compile TypeScript and bundle client for production
npm run server:start — run production build

Architecture

Server: Express + Socket.io on :3000; MCP SSE server on :3001
Client: React 18 + Vite
Database: SQLite via node:sqlite experimental (auto-created at data/orchestrator.db)
Agents: spawned as claude --print --output-format stream-json --verbose subprocesses

File Locking

A PreToolUse hook (scripts/check-lock-hook.mjs) blocks Edit/Write tool calls unless the agent holds a DB lock for that file. This applies to all Claude Code sessions running in this directory, including interactive ones.

Changes

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.
