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 | $0.00110 | $0.01742 |
| Opus 5.5 | $0.00044 | $0.00697 |
| Sonnet 5.5 | $0.00022 | $0.00348 |
| Haiku 4.5 | $0.00011 | $0.00174 |
Grade A, and why
presentation-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.

Presentation Builder
Overview
This skill turns a topic, document, or rough idea into a tight, persuasive presentation outline. It enforces three rules that separate good decks from forgettable ones:
- One core message — the whole deck exists to make ONE point land.
- A narrative arc — slides progress like a story (tension → resolution), not a list of facts.
- One idea per slide — each slide advances the argument by exactly one step, with spoken-word speaker notes.
Keywords: presentation, slide deck, slides, pitch deck, keynote, talk, lecture, demo, storytelling, narrative arc, speaker notes, outline, slide outline, deck structure, conference talk, sales pitch.
The output is a structured outline (slide-by-slide), NOT a visually rendered deck. Hand the outline to PowerPoint, Google Slides, Keynote, or a tool like Marp/reveal.js.
When to use vs. not use
- USE for: structuring a new deck, converting a document/report into slides, reordering a rambling deck, writing speaker notes, sharpening a pitch.
- DON'T over-engineer for: a single status slide, or when the user already has a finished deck and only wants visual styling (that's a design task, not a structure task).
Workflow
Follow these steps in order. Do not skip the discovery step — a deck built without knowing the audience and the ask is the #1 cause of bad presentations.
Step 1 — Discover the four anchors
Before writing any slide, establish (ask the user if unknown, max 3-4 crisp questions):
| Anchor | Question to answer |
|---|---|
| Audience | Who is in the room? What do they already know, care about, and fear? |
| Goal / Ask | What should they DO or DECIDE after the talk? (One verb.) |
| Core message | The single sentence they should remember tomorrow. |
| Constraints | Time limit, slide count, format (live/async), tone. |
If the user gave a document, infer drafts of these from it, then confirm the core message before proceeding.
What ships with it
5 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.

presentation-builder is a skill published in the GitHub repository JayRHa/AgentSkills (12 stars, last pushed 2mo ago), licensed MIT. It adds 110 tokens to every session and 1,742 once invoked, about $0.0004 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 2026-08-31.

cost-optimizer
Trigger when the user asks to audit Claude Code costs, reduce token spend, says "my Claude bill is too high", "optimize my CLAUDE.md", "why is this project burning tokens", or "/cost-optimizer". Scans a project for the common Claude Code cost leaks and returns a prioritized fix list.
excalidraw-architecture
Trigger when the user asks for an architecture diagram, says "draw the system", "update the architecture diagram", "give me an excalidraw of this codebase", or "/excalidraw-architecture". Generates or updates an Excalidraw JSON file at docs/architecture.excalidraw by reading the codebase's key entry points.
model-cost-compare
Trigger when the user asks which model to use, wants to compare model costs, says "what's cheapest for this task", "should I use Opus or Sonnet", "can a smaller model handle this", or "/model-cost-compare". Estimates token cost across Opus 4.6, Sonnet 4.6, GLM-5.1, Minimax M2.7, and local Gemma 4, then recommends the…
openclaw-debugger
Trigger when an OpenClaw agent is broken, silent, crashing, stuck, not responding, returning empty output, or the user says "my agent is down", "agent not working", "/openclaw-debugger". Walks through the standard OpenClaw 2026.4 diagnosis checklist and prints a report.
git-commit-writer
Trigger when the user asks to write a commit message, generate a commit from staged changes, review a diff before committing, or says "/commit". Reads git diff --staged and produces an opinionated, convention-matching commit message.
