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 | $0.00041 | $0.01328 |
| Opus 5.5 | $0.00016 | $0.00531 |
| Sonnet 5.5 | $0.00008 | $0.00266 |
| Haiku 4.5 | $0.00004 | $0.00133 |
Grade A, and why
draft-illustration 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.
This is a copy
97% identical to draft-illustration — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Post Visual Style (Cross-Repo)
Use this skill whenever you create or generate hero images, OG/social preview images, or any post artwork so that assets have the same visual style across repositories. The style is mandatory for blog/post imagery; repo-specific paths and scripts are documented per project.
Visual style (mandatory)
All hero and post imagery MUST follow this style. Apply it when prompting image generation (e.g. GenerateImage, DALL·E, Midjourney) or when briefing a designer.
Visual rules:
| Rule | Requirement |
|---|---|
| Background | Solid black only. No gradients, no white sections, no mixed backgrounds. |
| Foreground | White line-art. Subtle edge shading for dimensionality is encouraged; large filled areas and color gradients are not. |
| Line work | Polished, refined white outlines with consistent stroke weight. Lines should feel engraved or blueprint-quality — smooth curves, clean joints, slight dimensional depth on edges. Not sketchy or rough. |
| Color | Monochromatic black and white only. No gray tones or other colors outside of subtle edge shading for depth. |
| Composition | Scene-based or centered. Objects may sit on surfaces with perspective (e.g. an angled desk, a platform). Generous negative (black) space around the subject. |
| Aesthetic | Polished, dimensional, iconic. Technical engraving or refined blueprint feel. Not flat/clip-art, not photorealistic. Symbolic objects should feel like they have weight and presence. |
| Typography | None. No text, labels, or captions within the image. |
Focal brand: When the post is about a specific product or brand (e.g. Notion, Claude, OpenAI), focus the hero on that brand using recognizable shapes or motifs in the same white line-art style. No logos or wordmarks; the image should read as "this post is about X" at a glance.
Prompt template for image generation
When generating a new hero or post image, use a prompt that enforces the style. Example structure:
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.

draft-illustration is a skill published in the GitHub repository markmhendrickson/foundation (2 stars, last pushed 2mo ago), licensed MIT. It adds 41 tokens to every session and 1,328 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to draft-illustration, differing in 7 lines, and is treated as a copy.
