02Getting Started

Universal Installation

Install once globally, use with Claude, ChatGPT, Cursor, Gemini, VS Code, or Antigravity CLI.

npm install -g @aegis-skills/core
aegis init

aegis init will:

  • Detect your installed tools (Claude, ChatGPT, Cursor, Gemini, VS Code, Antigravity)
  • Interactively select which tools to configure
  • Inject skill manifests and system prompts to each tool
  • Save configuration to ~/.aegisrc

Available Commands

aegis list

Show installed skills and their status for each tool.

aegis configure --for <tool>

Reconfigure a specific tool (claude, chatgpt, cursor, gemini, vscode, antigravity-cli).

Audit API

POST to /api/audit to run a standards-based security audit against CIS, NIST CSF, ISO 27001, SOC 2, PCI-DSS, HIPAA, IEC 62443, or NIST 800-53.

POST /api/audit
{ "input": "<config or policy text>",
"inputType": "config",
"standards": ["cis-l1", "nist-csf"] }
03How it works
01

Write SKILL.md

Author your skill in a single markdown bundle — metadata, phases, and guidance in one file.

02

Compile artifacts

Run aegis compile — generates a system prompt, OpenAI action schema, and MCP manifest.

03

Deploy anywhere

Push to Vercel. Paste the system prompt or wire the MCP endpoint — done in minutes.
