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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00060 | $0.00363 |
| Opus 5 | $0.00030 | $0.00181 |
| Sonnet 5 | $0.00012 | $0.00073 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
demo-slideshow-edit 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 6d 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
Demo Slideshow Edit
Overview
Use this skill when the best output is a curated still-frame or segment-based reel rather than a full narrated playback. The slideshow must remain source-backed and evidence-linked.
Inputs
- storyboard frames or screenshots
- selected spans from
video.shots.json,segment.evidence.json, orevents.json - source
.demo.yamlor QA flow/report - target duration, aspect ratio, and audience
Workflow
- Select frames or spans that show state changes clearly.
- Reject frames that expose secrets, private data, or unreadable UI.
- Define the sequence with durations, crop/zoom notes, and transition notes.
- Prefer simple transitions and stable framing over decorative effects.
- Record the source path, evidence links, and output path in the artifact manifest when available.
- Produce a render plan or command. Do not claim the MP4 is approved until evidence and safety checks pass.
Output
Return:
- source run directory
- ordered frame/span list
- duration and aspect ratio
- output media path
- review surface path, if generated
- checks needed before handoff
Guardrails
- Do not fabricate app states that were not captured.
- Do not crop away failures, warnings, or key context.
- Do not use external stock or music unless the user explicitly asks and licensing is recorded.
- Keep generated slideshow media out of git unless explicitly promoted.
What ships with it
1 file 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.

demo-slideshow-edit is a skill published in the GitHub repository 45ck/skill-harness (15 stars, last pushed 2mo ago), licensed MIT. It adds 60 tokens to every session and 363 once invoked, about $0.0003 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 2026-08-30.
Other skills, from other repositories
post-acceptance
This skill should be used when the user asks to "prepare conference presentation", "create presentation slides", "design poster", "make academic poster", "write promotion content", "create Twitter thread", or mentions post-acceptance conference preparation. Provides comprehensive workflow for presentation, poster, and…
sc-skill
Capture deterministic macOS screenshots for testing, docs, release notes, and marketing assets. Use when asked to automate app screenshots, batch-generate screenshot sets, standardize window sizing/composition, or choose between Peekaboo and native macOS screenshot tooling.
presentation
Turn a tech-spec directory into an interactive, marketing-grade web presentation — built so engineers understand the design, the reader is convinced of the why, and the result is shareable in public. Use when someone wants a spec turned into a deck.
talk-stage5-script
Produces a complete 5-act pitch with speaker notes, a slide-by-slide specification, and a ready-to-paste Kimi prompt for AI slide generation. Requires validated angle and title from Stage 4. Use when you have a confirmed talk angle and need the full script, slide spec, and AI-generated presentation prompt.
do-it-architecture
Use when authority, ownership, contracts, dependency boundaries, migration, recovery, or structural deletion can change a design.
do-it-code-quality
Use when designing, changing, or debugging code to locate causal ownership and close the affected behavior.
