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

igniter-js writing-style.instructions.md 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 2mo 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.

✍️ Unified Documentation Style Guide (for LLMs & Authors)

This guide defines the writing standards for all Igniter.js content: documentation, blog posts, templates, and updates.

🎯 Core Style Principles (Applies to All Documentation)

  1. Clarity Over Cleverness
    Use simple, direct language. Favor short words and short sentences. Avoid jargon unless it's essential—and if it is, define it once.

  2. Speak Developer
    Write the way you'd speak to a smart, curious engineer sitting next to you. Friendly, confident, and precise.

  3. Show, Don't Just Tell
    Use examples liberally. Explain ideas with real code, not abstract theory. Every key concept should be backed by a working snippet.

  4. Write in Active Voice
    ✅ "Click the button to save your changes."
    ❌ "The button should be clicked in order for changes to be saved."

  5. Present First, Explain Later
    Get the reader to success as quickly as possible. After they've seen something work, then explain how/why it works.

  6. Be Honest and Human
    If something is tricky, say so. If you're recommending a workaround, explain why. Transparency builds trust.

  7. Use consistent terminology
    Always refer to concepts, components, and APIs by the same name. Don't mix "endpoint" and "route" if they mean the same thing.


📘 Documentation (Docs): Writing Style

Tone: Clear, technical, and helpful
Voice: An expert engineer sharing knowledge directly

✅ Style Rules:
  • Use second person ("you") to address developers directly
  • Always include conversational introduction paragraphs at the start of major sections explaining what, why, and how
  • Keep explanations focused and concise but provide enough context
  • Start with working examples, then explain concepts
  • Use <Callout> for important notes and warnings
  • Include complete, runnable code examples
  • Structure with <Steps> for sequential instructions (wrap in <Card> when representing complete guides)
  • Use <Tabs> for package manager commands (with groupId="package-manager")
  • Add <TypeTable> for API reference documentation
  • Show file structures with <Files>, <Folder>, <File> components
  • Convert lists to Accordions for "Best Practices", "Limitations", "Common Use Cases", and similar sections
  • Never include "Next Steps" sections in documentation articles (only in blog posts/tutorials)
  • Expand "Complete Example" sections with detailed introductory paragraphs explaining what the example demonstrates

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.
