style-guide-generator

style-guide-generator is an agent for coding agents from animalzinc/claude-plugins. It costs 19 tokens per session (1,141 once invoked), scanned A, original, MIT.

An article-analysis agent that studies published blog posts and turns their recurring writing patterns into a brand style guide.

In plain words
What is it for?
Use it to document voice, grammar, punctuation, formatting, technical standards, content patterns, industry terms, and a quick-reference checklist.
Why use it?
It makes editorial rules explicit instead of leaving writers to infer them from past articles.

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/animalzinc/claude-plugins/style-guide-generator
Clone the repo
git clone --depth 1 https://github.com/animalzinc/claude-plugins

Or install blog-style-guide-creator, the plugin that ships this one along with the rest of its 5 commands, 9 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

style-guide-generator 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 5d 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.

Analysis Methodology

For each section:

  • Identify patterns with 95%+ consistency → These become rules
  • Identify patterns with 70-95% consistency → These become preferences
  • Note intentional variations → These become exceptions

Analyze and document:

  • Em dash usage and spacing patterns
  • Quotation mark style (American vs. British)

4. Formatting

Analyze and document:

  • Heading hierarchy (H1, H2, H3, H4)
  • List types and when to use each (bulleted vs numbered)
  • Bold and italics usage patterns
  • Hyperlink anchor text style
  • Image caption formatting

5. Technical Standards

Analyze and document:

  • Date formats
  • Time formats
  • Percentage formatting
  • Read time indicators
  • Currency formatting
  • Number formatting in data/statistics

6. Content Patterns

Analyze and document:

  • Article title structure and optimal length

  • Byline and author bio formats
  • Article structure patterns

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.
