A Claude Code plugin for coordinating several specialised AI agents through an MCP server, a standard way for an AI tool to call external capabilities. It includes shared memory, approval checkpoints and GitHub workflow support.

Use it to run multi-agent coding workflows, preserve context between agents or sessions, request human approval for high-impact actions, and work with GitHub processes.

It lets different agents divide work and share context instead of relying on one agent to do everything. Approval checkpoints can require a person to approve risky actions before they proceed.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/blackms/aistack

Made for: Claude Code.

Security

Grade A, and why

aistack 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 2mo 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.

What it installs

The manifest is a name and a version. 3 skills, 3 commands travel with it, and installing the plugin installs all of them — 368 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
