What is aghub CLAUDE.md?

A project guide for aghub, a command-line tool that manages settings for multiple AI coding agents.

Finding common development commands, running individual or integration tests, checking code quality, and trying aghub with different agents.

It gives contributors the project background and the exact commands for building, testing, checking, formatting, running, and installing the tool.

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	$0.05671	$0.05671
Opus 5.5	$0.02268	$0.02268
Sonnet 5.5	$0.01134	$0.01134
Haiku 4.5	$0.00567	$0.00567

Security

Grade A, and why

aghub 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 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.

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.

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

Project Overview

aghub is a CLI tool (aghub-cli) for managing AI coding agent configurations. It supports 22 agents (Claude, OpenCode, Cursor, Windsurf, Copilot, RooCode, Cline, Gemini, Codex, Zed, Warp, and more), handling MCP servers and skills through a unified interface. Full agent list: crates/core/src/models.rs or aghub-cli --help.

Common Commands

Use just for task running:

# Build
just dev          # Debug build
just build        # Release build

# Test
just test         # Run all tests
just integration-test  # Run integration tests only
just test-with-validation  # Tests requiring real CLI tools installed (claude, opencode, etc.)

# Lint/Format
just lint         # Run clippy with warnings as errors
just fmt          # Format code

# Run
just start -- --help                    # Run with cargo
just start -- -a claude get skills      # List skills
just start -- -a claude get mcps        # List MCP servers
just install                            # Release build → ~/.cargo/bin/

Run a single test: cargo test --package aghub-core test_name -- --exact

Architecture

Workspace Structure

crates/core (aghub-core): Core library with models, config management, and agent adapters
crates/cli (aghub): CLI binary (aghub-cli) with clap-based commands
crates/skills-sh: HTTP API client for skills.sh registry (SKILLS_API_URL env var overrides base URL)
crates/skills-ref (skills-ref): Parses SKILL.md files, validates SkillProperties, generates XML prompt blocks via to_prompt()
crates/skill (skill): Extends skills-ref with .skill zip format; parse() auto-detects directory/zip/SKILL.md. Called by manager.add_skill_from_path()
crates/prompt (aghub-prompt): Local prompt-library storage — Prompt model plus a JSON-file PromptStore (CRUD over prompts.json in the app data dir) and {{variable}} extraction
crates/api: Rocket-based HTTP API server exposing agent config operations over HTTP

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.
