mir-skills-install

mir-skills-install is a skill for Claude Code, Codex from mir-am/skills-agents-ai-coding. It costs 37 tokens per session (370 once invoked), scanned A, original, MIT.

A command-line setup workflow that installs every skill in a repository for Codex, Claude Code, GitHub Copilot, and OpenCode. It uses npx, a tool that runs packages from the Node.js ecosystem.

In plain words
What is it for?
Use it when you want to install this repository's skills globally for all four supported coding assistants.
Why use it?
It avoids installing each skill and each supported coding assistant separately. It also reports missing prerequisites or installation errors instead of claiming success.

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.

Security

Grade A, and why

mir-skills-install 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 14d 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 actually says

What I do

  • Check that npx is available
  • Install all repository skills globally for four explicit agent targets
  • Report success or the install command's error

When to use me

Use when the user wants to install this repository's skills, including newly added skills, for Codex, Claude Code, GitHub Copilot, and OpenCode. Invocation authorizes the global installation without another confirmation prompt.

Workflow

Run this exact command after checking for npx:

(
set -e
if ! command -v npx >/dev/null 2>&1; then
  echo 'Error: npx not found. Install Node.js and npm, then retry.' >&2
  exit 1
fi

npx -y skills@latest add mir-am/skills-agents-ai-coding \
  -g --skill '*' -a codex claude-code github-copilot opencode -y
)

Keep the quoted '*', both -y flags, global scope, and all four explicit agent targets; do not replace them with --all.

  • On exit code 0, report that the repository skills were installed globally for Codex, Claude Code, GitHub Copilot, and OpenCode.
  • If npx is missing, report the prerequisite error and stop.
  • On any other failure, report the exit code and command error without claiming success or silently retrying with different flags.
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.
