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 5.1 | $0.00054 | $0.00319 |
| Opus 5.5 | $0.00022 | $0.00128 |
| Sonnet 5.5 | $0.00011 | $0.00064 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
slide-deck-builder 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
Slide Deck Builder
Build a coherent deck whose narrative and visual output both survive review.
Workflow
- Identify source decks, template or theme, audience, duration, aspect ratio, required slides, assets, and output format.
- Inspect layouts, masters, fonts, notes, charts, links, media, and existing slide dimensions. Reuse established components and styles where possible.
- Outline the narrative before editing. Keep claims, source notes, speaker guidance, and open questions distinguishable; do not invent data or citations.
- Create or modify slides with consistent hierarchy, readable text, aligned objects, meaningful alt text when supported, and sensible fallback for missing assets.
- Render the full deck and inspect title, dense, chart, image, transition, and final slides. Check for overflow, clipping, missing fonts, contrast, broken links, and unwanted blank slides.
- Report the output path, narrative changes, render checks, sources, and items requiring human review.
Boundaries
- Do not overwrite the only source deck or fetch copyrighted or external assets without authorization.
- Do not treat a successfully generated presentation as visually validated until it has been rendered or structurally checked.
- Keep secrets and personal data out of slide notes, screenshots, logs, and examples.
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.

slide-deck-builder is a skill published in the GitHub repository lfyxhappy/lfcode (2 stars, last pushed 1mo ago), licensed MIT. It adds 54 tokens to every session and 319 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-05.
