hello

hello is a skill for Claude Code, Codex from jjanczur/tyran. It costs 24 tokens per session (133 once invoked), scanned A, original, Apache-2.0.

An installation check for the Tyran plugin. It confirms the plugin is loaded, reports its version, and shows where it is installed.

In plain words
What is it for?
Use it to run a quick Tyran installation smoke test with `/tyran:hello`. It does not perform other work.
Why use it?
It helps verify that the plugin is installed, correctly namespaced, and resolving its installation path as expected.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the tyran plugin — 15 skills, 5 agents, 5 hooks shipped together

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.

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

hello 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 5d 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

Hello (installation smoke test)

Reply with exactly one short paragraph:

  1. Confirm the Tyran plugin is loaded and state its version by reading ${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json.
  2. State the resolved value of ${CLAUDE_PLUGIN_ROOT} so the user can see where the plugin is installed from.

Do not perform any other action. This skill exists only to verify installation, namespacing, and path resolution.

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.
