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

vulcan 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.

Origin

This is a copy

100% identical to vulcan — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Vulcan Skill Pack

Canonical source: ../../vulcan-cli-master/skills/vulcan/SKILL.md

Load order for solana-clawd perps work:

  1. Read ../../vulcan-cli-master/CONTEXT.md.
  2. Read ../../vulcan-cli-master/skills/INDEX.md.
  3. Read this entry skill's canonical source.
  4. Load focused skills from skills/vulcan-* as needed.

Non-negotiable runtime rules:

  • Paper and dry-run modes must never require wallet signing.
  • Live/dangerous operations require explicit user approval and Vulcan --yes or MCP acknowledged=true.
  • Before opening exposure, inspect market, margin, and current positions.
  • Never guess lot sizes; use vulcan-lot-size-calculator.
  • Never read, print, export, or infer private keys, wallet passwords, or MCP config secrets.
  • Report every execution event and full transaction signature immediately.

This wrapper exists so solana-clawd exposes the bundled Vulcan skill pack from its own skills/ catalog while preserving Vulcan's upstream docs as authoritative.

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.
