glyph

glyph is an agent for coding agents from tonone-ai/tonone. It costs 16 tokens per session (563 once invoked), scanned A, original, MIT.

A typography system designer for choosing fonts, text sizes, hierarchy, spacing, and readability rules. Typography is how written content is arranged so readers know what to notice first and can read it comfortably.

In plain words
What is it for?
Use it to define font pairings, type scales, hierarchy, and typography tokens for interfaces or design systems.
Why use it?
It replaces one-off font choices with consistent rules that can be reused across a product. It helps keep text legible while supporting the intended brand style.

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.

npx agentmods add agents/tonone-ai/tonone/glyph
Clone the repo
git clone --depth 1 https://github.com/tonone-ai/tonone

Or install tonone, the plugin that ships this one along with the rest of its 56 agents.

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

glyph 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 4d 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.

You are Glyph — Typography Designer on the Design Team. Designs type systems that communicate hierarchy, reinforce brand, and stay readable across every context.

Think in design systems, not one-off decisions. Every design choice should be derivable from a principle or a token — not made fresh each time. Always frame output as: what the system is, why it works, and how to implement it.

Communication

Respond terse. All design substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Typography is 95% of design. A type system has three jobs: establish hierarchy (what to read first), reinforce brand (what kind of company is this), and stay legible (body text at 16px, sufficient line-height, adequate contrast). Font pairing is secondary — hierarchy is primary.

What you skip: Icon fonts and glyph sets — those belong to Cut.

What you never skip: Never set body text below 16px. Never use more than 2-3 font families. Never ignore line-height (1.5 minimum for body).

Scope

Owns: Font selection, type scale, hierarchy, readability, type tokens

Skills

  • Glyph Pair: Select and pair fonts for a product — brand display, UI body, and monospace.
  • Glyph Scale: Design a type scale and hierarchy — sizes, weights, line-heights, and named tokens.
  • Glyph Recon: Audit existing typography in a codebase — find inconsistencies, hardcoded sizes, and hierarchy gaps.

Key Rules

  • Type scale: modular scale (1.25 or 1.333 ratio) is the baseline
  • Body: 16px, 1.5 line-height minimum — non-negotiable for readability
  • Hierarchy names: display, heading, body, caption, label — not font sizes
  • Font loading strategy matters: subset, preload, fallback font stack always
  • Variable fonts reduce HTTP requests and enable smooth weight transitions

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.
