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 B, and why

cyrus-setup-github scanned grade B with 2 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 349 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CRITICAL: Never use Read, Edit, or Write tools on ~/.cyrus/.env or any file inside ~/.cyrus/. Use only Bash commands (grep, printf >>, etc.) to interact with env files — secrets must never be read into the conversation context.

Setup GitHub

Configures GitHub CLI and git so Cyrus can create branches, commits, and pull requests. Optionally creates a GitHub App so Cyrus can receive and respond to @mentions in PR comments and reviews, automate rebases and merges, and auto-fix based on CI failures (coming soon).


Part A: GitHub CLI + Git Config (Outbound)

Step 1: Check Existing Configuration

Check if gh is already authenticated:

gh auth status 2>&1

If authenticated, check git config:

git config --global user.name
git config --global user.email

If both gh auth and git config are set, inform the user:

GitHub is already configured. Skipping to webhook setup.

Skip to Part B.

Step 2: Authenticate GitHub CLI

If gh is not authenticated:

gh auth login

This opens an interactive browser flow. Let the user complete it.

After completion, verify:

gh auth status

Step 3: Configure Git Identity

If git user name or email are not set, ask the user for their preferred values:

What name should appear on commits made by Cyrus? (e.g., your name, or "Cyrus Bot")

What email should appear on commits? (e.g., your email, or a noreply address)

Then set them:

git config --global user.name "<name>"
git config --global user.email "<email>"

Step 4: Verify

gh auth status
git config --global user.name
git config --global user.email

Part B: GitHub App + Webhooks (Inbound — Optional)

Ask the user:

Do you want Cyrus to respond to GitHub @mentions in PR comments and reviews?

  • Yes — enable @mentions: Creates a GitHub App so Cyrus can receive PR comments and reviews via webhooks, respond when @mentioned, and act on "changes requested" reviews.
  • No — PRs only: Cyrus will create branches, commits, and PRs but won't respond to comments.

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.

cyrus-setup-github is a skill published in the GitHub repository cyrusagents/cyrus (856 stars, last pushed 2d ago), licensed Apache-2.0. It adds 54 tokens to every session and 3,301 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
