In plain words

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

copywriter 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 8d 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.

UX Writing Patterns

Button Labels

// ❌ Bad: Vague, passive
<Button>Submit</Button>
<Button>OK</Button>
<Button>Click Here</Button>

// ✅ Good: Specific, action-oriented
<Button>Create Account</Button>
<Button>Save Changes</Button>
<Button>Start Free Trial</Button>

Guidelines:

  • Use verb + noun ("Save Changes" not "Save")
  • Be specific ("Delete Post" not "Delete")
  • Show outcome ("Start Free Trial" not "Submit")

Error Messages

// ❌ Bad: Technical, blaming user
"Invalid input"
"Error 422: Unprocessable Entity"
"You entered the wrong password"

// ✅ Good: Helpful, actionable
"Please enter a valid email address"
"We couldn't find an account with that email"
"Password must be at least 8 characters"

// Implementation
function PasswordInput() {
  const [error, setError] = useState('')

  const validate = (password: string) => {
    if (password.length < 8) {
      setError('Password must be at least 8 characters')
    } else if (!/[A-Z]/.test(password)) {
      setError('Password must include at least one uppercase letter')
    } else if (!/[0-9]/.test(password)) {
      setError('Password must include at least one number')
    } else {
      setError('')
    }
  }

  return (
    <div>
      <input type="password" onChange={(e) => validate(e.target.value)} />
      {error && <p className="text-red-600">{error}</p>}
    </div>
  )
}

Error Message Formula:

  1. What happened
  2. Why it happened (optional)
  3. How to fix it

What ships with it

2 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.
