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

thrunt-update 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 9d 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

  • Version detection (local vs global installation)
  • npm version checking
  • Changelog fetching and display
  • User confirmation with clean install warning
  • Update execution and cache clearing
  • Restart reminder

<execution_context> @.github/thrunt-god/workflows/update.md </execution_context>

The workflow handles all logic including:

  1. Installed version detection (local/global)
  2. Latest version checking via npm
  3. Version comparison
  4. Changelog fetching and extraction
  5. Clean install warning display
  6. User confirmation
  7. Update execution
  8. Cache clearing

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.
