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

html-deck 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 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.

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

Treat $1 as the presentation brief, topic, or source file path. If $1 is missing, ask the user for the deck topic, audience, target slide count, and preferred visual system (Product Grid v2 by default).

Find <skill-dir> before starting. @citedy/skills only — AdClaw uses ~/.adclaw/active_skills/html-presentation-deck instead (see SKILL.md).

  • .codex/skills/html-presentation-deck when this command lives under .codex/commands/.
  • .claude/skills/html-presentation-deck when this command lives under .claude/commands/.
  • If both exist, prefer the namespace that matches the invocation; otherwise use the one that exists.

Read <skill-dir>/SKILL.md and follow the workflow.

Create a standalone HTML deck at deck/index.html, then validate:

python3 <skill-dir>/scripts/validate_html_deck.py deck/index.html
python3 <skill-dir>/scripts/validate_deck_quality.py deck/index.html

Run validate_deck_quality.py only for Product Grid v2 decks (data-system="product-grid").

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.
