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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00074 | $0.01011 |
| Opus 5 | $0.00037 | $0.00505 |
| Sonnet 5 | $0.00015 | $0.00202 |
| Haiku 4.5 | $0.00007 | $0.00101 |
Grade A, and why
design-simple-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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Simple Deck Skill
Produce a single-file horizontal-swipe HTML deck using the seed and layout library.

Workflow
Step 0 — Pre-flight
- Read
assets/template.htmlend-to-end through the<style>block AND the<script>block. The script solves five iframe-specific bugs (real scroller detection, dual capture-phase listeners, auto-focus, noscrollIntoView, position persistence) — do not rewrite it. - Read
references/layouts.mdso you know the 8 layouts. Pay special attention to the "Theme rhythm" section — it's the rule that prevents the deck from feeling sleepy. - Read the active DESIGN.md — map its tokens to the six
:rootvariables in the seed.
Step 1 — Copy the seed
Copy assets/template.html to the project root as index.html. Replace the six :root variables with the active design system's tokens. Replace the page <title>.
Step 2 — Decide slide count + theme rhythm BEFORE writing any slide
Default: 6 slides unless the brief says otherwise.
| Audience / format | Slides |
|---|---|
| Product overview / lightning talk (5–10 min) | 6 |
| Pitch deck (15 min) | 8–10 |
| Investor update / longer talk (20–30 min) | 12–18 |
Then write out the rhythm before any HTML — for example, 8 slides:
01 hero light center Cover
02 light Problem
03 hero dark center Big stat
04 light Three points
05 dark Pipeline
06 hero light center Quote
07 light Before / after
08 hero dark center Ask
A healthy sequence has:
- No 3+ same theme in a row
- ≥ 1
hero darkAND ≥ 1hero light(for 8+ slides) - Alternating breath every 3–4 slides
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-simple-deck is a skill published in the GitHub repository the-sid-dani/second-brain-os (2 stars, last pushed 29d ago), licensed MIT. It adds 74 tokens to every session and 1,011 once invoked, about $0.0004 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.

dr-fanout
One command to fan a Deep Research prompt out to several external LLMs at once (ChatGPT / Gemini / Grok / others) through the operator's logged-in browser, then collect the reports, archive the originals, and synthesize a consensus. Trigger on "/dr-fanout", "fan out the DR", "distribute the research prompt". Automates…
journey
Resurrect and continue a build-in-public BOOK — the serialized story of a founder + AI- cofounder journey. One command: pick up state (which days are written in which languages, what's uncommitted, where the gaps are), then continue writing via the established pipeline. Trigger on "/journey", "the book", "continue the…

Onboard a NEW family/team machine as a FOLLOWER-CONSUMER joining the multi-machine Claude+vault network. A follower READS the shared vault + canon + skills + memory as RECEIVE- ONLY data, runs nothing heavy locally (no RAG/reindex/GPU), and the hub never pushes executable hooks to it. Trigger on "/follower-onboard "…
