What is glyphs-sdk-reference?

A programming reference for building Glyphs.app plugins with the GlyphsSDK. Glyphs.app is font-design software, and the SDK provides base classes, templates, and examples for its plugin types.

Use it to look up plugin methods, browse Python templates and samples, and understand GlyphsReporter, GlyphsFilter, and GlyphsPalette plugins.

It makes plugin lifecycle methods and example implementations easier to find than reading the SDK source manually.

Install

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.

Any agent

npx skills add yintzuyuan/glyphs-reference --skill glyphs-sdk-reference

Clone the repo

git clone --depth 1 https://github.com/yintzuyuan/glyphs-reference

Made for: Claude Code.

Or install glyphs-reference, the plugin that ships this one along with the rest of its 10 skills, 1 agent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.00907
Opus 5	$0.00031	$0.00453
Sonnet 5	$0.00012	$0.00181
Haiku 4.5	$0.00006	$0.00091

Security

Grade A, and why

glyphs-sdk-reference 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 9d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/_sdk_utils.py, scripts/list_templates.py, scripts/read_template.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

GlyphsSDK Reference

Plugin development reference extracted from GlyphsSDK. Covers plugin base class methods, templates, and sample implementations.

Scripts

Run all scripts from this skill's base directory. Prepend the base directory path to scripts/ when executing.

Script	Purpose	Output
`search_methods.py`	AST analysis of plugins.py — 7 plugin base classes and their methods	Classes + methods with type classification
`list_templates.py`	List all Python Templates (9) and Samples (6)	Name + type + plugin_type + path
`read_template.py`	Read template/sample source code + README + AST info	Source + classes + imports + readme

Usage

Plugin Methods

# List all 7 plugin base classes with methods
python scripts/search_methods.py

# Methods for a specific plugin type
python scripts/search_methods.py --plugin reporter

# Search methods across all classes
python scripts/search_methods.py --search foreground

# Identify a specific method
python scripts/search_methods.py --method drawForegroundForLayer_options_

Method type classification:

Type	Meaning	AST rule
`protocol`	ObjC protocol method	Name ends with `_`
`python_helper`	Python convenience method	Has `@objc.python_method` decorator
`python_wrapped`	Python method override	Other methods

Templates & Samples

# List all templates + samples
python scripts/list_templates.py

# Only templates
python scripts/list_templates.py --type template

# Only samples
python scripts/list_templates.py --type sample

Read Source Code

# Read a template (with README)
python scripts/read_template.py reporter

# Filter with specific variant
python scripts/read_template.py filter --variant "without dialog"

# Read a sample by name
python scripts/read_template.py "Smiley Panel Plugin"

# Read drawingTools.py
python scripts/read_template.py --drawing-tools

What ships with it

10 files 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.

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.
