Openrouter Install Auth

What it does

When your agent uses it

• Starting a new OpenRouter integration
• Troubleshooting auth issues

Example prompts

• “openrouter setup”
• “openrouter api key”
• “configure openrouter auth”
• “/openrouter-install-auth”

Requirements

• Python 3
• Node.js
• A credential in OPENROUTER_API_KEY
• A credential in MGMT_KEY
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Bash(python3:*), Bash(node:*), Bash(pip:*), Bash(npm:*)

Workflow steps

5 steps, taken from the step headings in SKILL.md.

1. 1Generate an API Key
2. 2Configure Environment
3. 3Initialize the Client
4. 4Verify Authentication
5. 5Send a Test Request

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Grep
  • Bash(python3:*)
  • Bash(node:*)
  • Bash(pip:*)
  • Bash(npm:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • pip
  • npm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • openrouter.ai

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • OPENROUTER_API_KEY
  • MGMT_KEY
  • OPENROUTER_MGMT_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Openrouter Install Auth loads about 1.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 399 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~68

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
