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

validate-plan 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

Validate the provided technical implementation plan for compliance with homelab security, architectural, and documentation standards.

Instructions

  1. Read the plan: If a file path was provided, read its content. If raw text was provided, use that.
  2. Apply validation rules:
    • Check for sensitive data (API keys, secrets) — MUST NOT be present.
    • Verify credential loading pattern — MUST use scripts/load-env.sh and ~/.claude-homelab/.env.
    • Verify documentation — MUST include README.md, SKILL.md, and references.
    • Check for confirm=True gate on destructive actions.
    • Ensure standard directory structure (scripts/, references/, examples/).
  3. Report findings: Provide a structured report with 'Compliance Check' table and 'Required Changes' list.

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.
