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 | $0.00016 | $0.01876 |
| Opus 5 | $0.00008 | $0.00938 |
| Sonnet 5 | $0.00003 | $0.00375 |
| Haiku 4.5 | $0.00002 | $0.00188 |
Grade A, and why
draw-your-font 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 11d 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
100% identical to draw-your-font — 0 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
draw-your-font
Photo of handwritten letters in → installable font out. You do the seeing (find and label letters, judge quality); the CLI does all geometry (trace, metrics, font assembly). Never edit SVG paths or coordinates yourself.
Setup in Hermes (once per session)
The CLI is the pinned npm package [email protected] — run it via npx (Node ≥ 18 required, no global install needed):
npx -y [email protected] --help
Wherever the examples below show $DYF, use npx -y [email protected]. Shell variables do not persist between tool calls, so paste the full command each time. Everything runs locally; the user's handwriting never leaves the machine.
Photos arrive in Hermes either as a file path in the message or via the gateway image cache — use the actual file path with the CLI. When a photo lands in the conversation with no path, ask the user for the file (the CLI needs a real file, not your memory of the image).
Do the visual steps (contact sheets, previews, glyph sheets) by loading the PNGs with vision_analyze.
Decide the flow
- User has no photo yet → offer the template: print, write, photograph.
- User shares photo(s) of handwriting → main flow below.
- User pasted an image but there is no file path → you can see it, but the CLI needs a file. Ask them to drag the image file into the terminal (that inserts its path) or give the path directly. Do not proceed from memory.
- User wants changes to a font built this session → Refine section.
Template flow (best quality)
$DYF template -o template.pdf --charset minimal # or: spanish
Tell the user: print it, write one character per box with a dark pen (0.5 mm+), keep the letter sitting on the solid line, then photograph each page from above in good light and share the file paths. The grid prints in light grey and vanishes during processing - only their ink survives.
Main flow: photo(s) → font
1. Segment. Works for template pages and freeform photos alike:
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.
