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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01526 |
| Opus 5 | $0.00024 | $0.00763 |
| Sonnet 5 | $0.00010 | $0.00305 |
| Haiku 4.5 | $0.00005 | $0.00153 |
Grade A, and why
presentations 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 4d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Presentation Strategy and Best Practices
Structured frameworks for planning, structuring, and designing effective presentations for any audience.
Core Frameworks
Problem-First Framing (Pyramid Principle)
Lead with the answer or recommendation first, then supporting evidence. Never open with "how we did it" — open with "what the problem is and what we recommend."
SCQA Structure:
- Situation — the stable context the audience already knows
- Complication — what changed or went wrong
- Question — the question the complication raises
- Answer — the recommendation (state this first, then support it)
Apply SCQA to the opening slide before revealing methodology or detail.
See references/frameworks.md for worked SCQA examples and Pyramid Principle depth.
Rule of Threes
Limit each presentation to 3 key messages. Structure each key message with 3 supporting arguments. Use a 3-act arc: setup → confrontation → resolution.
- Cognitive basis: working memory handles 3 items reliably
- Apply at the deck level (3 sections) and the slide level (3 bullets max)
- When you have more than 3 points, find the grouping pattern, not more slides
Assertion-Evidence Slide Design
Every slide follows this structure:
- Top of slide: A single declarative assertion — 2 lines maximum, ~10-15 words
- Body: Visual evidence supporting the assertion (diagram, chart, image, table)
- Target ~20 words total per slide (assertion + any labels)
- Replace bullet lists with visual evidence wherever possible
Bad assertion (topic label): "Q3 Performance" Good assertion (claim): "Q3 latency dropped 40% after cache rollout"
Guy Kawasaki 10/20/30 Rule
- Maximum 10 slides per deck
- Maximum 20 minutes of speaking time
- Minimum 30pt font size
Apply as a constraint check after structuring the deck. If a draft exceeds 10 slides, identify which slides can merge, become appendix, or be cut.
Nancy Duarte Sparkline
Frame the narrative as a contrast between "what is" (current reality) and "what could be" (future vision). Make the audience the hero of the transformation, not the presenter or product.
What ships with it
7 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.

presentations is a skill published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 1,526 once invoked, about $0.0002 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 2026-09-04.
