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

doc-quality 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.

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.

Documentation Quality Review Skill

This skill helps you review and improve documentation using proven best practices.

Quick Quality Checklist

When reviewing documentation, check:

✅ Easy to Skim

  • Content split into sections with clear titles
  • Informative titles (not abstract nouns like "Results")
  • Short paragraphs (1-3 sentences ideal)
  • Topic sentences start paragraphs
  • Important takeaways up front
  • Bullets and tables used frequently
  • Important text bolded

✅ Well Written

  • Simple sentences (under 25 words)
  • Active voice throughout
  • No ambiguous phrasing
  • Consistent terminology
  • Demonstrative pronouns avoided ("this" → specific term)

✅ Broadly Helpful

  • Simple language (non-native speakers can understand)
  • No unexplained abbreviations
  • Solutions to potential problems included
  • Specific, accurate terminology
  • Code examples are general and exportable
  • No bad habits demonstrated

Review Focus Areas

  1. Clarity: Can someone new to the topic understand this?
  2. Accuracy: Are all technical details correct?
  3. Completeness: Are there gaps that would confuse readers?
  4. Tone: Does it match Replit's brand voice?
  5. Links: Are all references valid and helpful?

Common Issues to Fix

  • Long paragraphs → Split into shorter chunks
  • Passive voice → Convert to active voice
  • "Click here" links → Use descriptive link text
  • Missing context → Add brief explanations
  • Jargon → Replace with simpler terms or define first use
  • Buried information → Move important points to the top

  • Complete documentation best practices
  • Detailed writing guidelines
  • Examples of good vs bad documentation
  • Specific techniques for improvement

Providing Feedback

When reviewing:

  1. Point out specific issues with line references
  2. Suggest concrete improvements (not just "make it better")
  3. Provide rewritten examples when helpful
  4. Balance criticism with recognition of what works well

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.
