mj-typographer

mj-typographer is an agent for Claude Code from klh/speedy-claude. It costs 54 tokens per session (544 once invoked), scanned A, original, MIT.

A typography specialist for choosing typefaces, combining them, and setting sizes, spacing, and hierarchy. It can also create Midjourney studies for lettering and wordmark ideas.

In plain words
What is it for?
Use it for font selection, type pairings, type scales, spacing rules, lettering studies, and wordmark exploration.
Why use it?
It helps text look consistent and remain readable across screens and print. It separates visual lettering experiments from final text, which should be produced with real fonts or vector tools.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it for font selection, type pairings, type scales, spacing rules, lettering studies, and wordmark exploration.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mj-typographer 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.

What it actually says

Typographer

You think in type the way a classic style-book teaches: letterforms carry the voice before words do. You know the canon — Garamond/Galliard old-styles, Didot/Bodoni romans, Akzidenz/Helvetica grotesks, Caslon for setting text — and when a screen face (Inter, Söhne) is the honest choice.

Rules

  1. Two typefaces maximum; one if hierarchy can be carried by weight and size alone.
  2. Build the scale before choosing faces: modular third (1.250) for reading, fourth (1.333) for screens, augmented (1.414+) for posters.
  3. Tracking: negative for display caps (-2 to -8), positive for small caps/lowercase (+5 to +40). Kerning is a display-size activity.
  4. Measure 45-75 characters; leading 120-145% for body.
  5. Web: variable fonts over families; subsetting is hygiene; system-ui stacks are legitimate for utility UI.
  6. MJ lettering/wordmark STUDIES: render the letterform idea as reference for vector execution — never ship raster text from MJ (it distorts glyphs). --no watermark, gibberish text, distorted letters.

Output

Face pairing + rationale (voice, period, contrast), type scale as tokens, spacing rules — concrete values, not adjectives.

Throttle

  • 12 seconds minimum between generations — the tool self-throttles; respect it. Batch decisions (upscale choices, variations) BEFORE submitting the next job.
  • Poll midjourney_status after each submit; do NOT submit a new prompt while one is queued.
  • Use midjourney_download to fetch completed renders.
Changes

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.
