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

setup-github 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 6d 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.

GitHub App Setup

Guide the human through creating and configuring a GitHub App for their wolt. Step by step, one at a time.

This skill is idempotent — safe to run again. If things are already configured, validate and skip.

Step 0: Check existing config

Check if GitHub App credentials are already configured:

grep -c "GITHUB_APP_ID" "$WOLTSPACE_WOLT_DIR/.env" 2>/dev/null && echo "found" || echo "not found"

If already configured: Validate the credentials work:

gh-app-token >/dev/null 2>&1 && echo "✓ GitHub App auth working" || echo "✗ Auth failed"

If working, tell the human and stop. If auth fails, continue to help fix it.

Step 1: Create a GitHub App

Tell the human:

Go to https://github.com/settings/apps/new and fill in:

  • App name: anything unique (e.g. woltspace-yourusername)
  • Homepage URL: https://github.com/jerpint/woltspace (or your fork)
  • Webhook: uncheck "Active" — we don't need webhooks
  • Permissions → Repository:
    • Issues: Read & write
    • Pull requests: Read & write
    • Contents: Read & write (for pushing branches)
  • Click Create GitHub App

Wait for confirmation before continuing.

Step 2: Generate a private key

Tell the human:

On your new App's settings page, scroll down to Private keys and click Generate a private key.

A .pem file will download. Open it in a text editor and copy the full contents (including the BEGIN/END lines).

Paste it here.

Once they paste it, format for .env — replace actual newlines with \n so it fits on one line:

# The key should look like: -----BEGIN RSA PRIVATE KEY-----\nMIIE...\n...\n-----END RSA PRIVATE KEY-----

Add to .env:

GITHUB_APP_PRIVATE_KEY=-----BEGIN RSA PRIVATE KEY-----\nMIIE...\n-----END RSA PRIVATE KEY-----

Step 3: Get the App ID

Tell the human:

On your App's settings page, near the top you'll see App ID — it's a number. Paste it here.

Add to .env:

GITHUB_APP_ID=<app_id>
