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 | $0.00045 | $0.00759 |
| Opus 5.5 | $0.00018 | $0.00304 |
| Sonnet 5.5 | $0.00009 | $0.00152 |
| Haiku 4.5 | $0.00005 | $0.00076 |
Grade A, and why
sg-build 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slide Generator: Build Step
Assemble the final PowerPoint file (.pptx) from the presentation markdown and generated images. Uses python-pptx to create a professional slide deck with the selected template.
Pre-loaded Context
Working directory:
!pwd
Available presentation files:
!ls -la *.md 2>/dev/null | grep -i pres || echo "No presentation files found"
Available images:
!ls images/ 2>/dev/null | wc -l || echo "0"
Available templates:
!sg list-templates 2>&1 || echo "Cannot list templates"
Prerequisites
- Preflight:
sg --versionmust succeed before proceeding — ifsgis missing, stop and tell the user this requires the privatedavistroy/slide-generatorengine (owner-only; see ADR-0008) slide-generatorpackage installed- A
presentation.mdfile with slide content - Generated images in
images/directory (optional — builds without images if missing)
Input Validation
Required:
<presentation.md>- Path to presentation markdown file
Optional:
--template <name>- Template to use (default:generic). Usesg list-templatesto see options--style <path>- Custom style JSON file for colors, fonts, sizing--output <path>- Output .pptx file path
Instructions
- Verify input: Confirm presentation markdown and images exist
- List templates (if user hasn't specified):
sg list-templates - Run build:
sg build presentation.md --template generic - Verify output: Confirm .pptx file was created
- Report results: Show file path, file size, slide count
How It Works
The build step:
- Parses markdown into structured slide data (titles, bullets, notes, image refs)
- Classifies each slide type (title, content, two-column, image-heavy, etc.)
- Applies template layout rules for each slide type
- Embeds generated images at appropriate positions
- Adds speaker notes, slide numbers, and footers
- Uses dynamic year detection for copyright footers
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.

sg-build is a skill published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 19d ago), licensed MIT. It adds 45 tokens to every session and 759 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 2026-09-04.
