html-deck

A workflow for creating a browser-based presentation as a standalone HTML file. It accepts a topic, brief, or source file and validates the finished deck with provided checks.

In plain words
What is it for?
Use it to create and validate an HTML slide deck from a topic, brief, or source file.
Why use it?
It turns presentation requirements into a web page that can be opened in a browser and checks the result for technical and, where applicable, visual quality issues.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 266 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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").

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.

html-deck is a command published in the GitHub repository citedy/skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 7 tokens to every session and 266 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
