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

file-upload-patterns 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 4d 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.

What it actually says

File Upload Patterns

Upload Patterns

Single File

  • Button: "Choose File" or styled dropzone.
  • Show filename + size after selection.
  • Progress bar during upload.
  • Success: checkmark + filename. Error: red text + retry.

Multi-File

  • Drag and drop zone with file list below.
  • Individual progress bars per file.
  • Allow removing files before/during upload.
  • Show total progress: "3 of 7 files uploaded."

Image Upload

  • Preview thumbnail after selection.
  • Crop/resize tool for profile photos.
  • Max size warning before upload starts.
  • Format validation: show accepted formats.

Validation

  • Check file type on selection (before upload).
  • Check file size on selection (before upload).
  • Show accepted formats near the upload control.
  • Server-side validation as backup (never trust client only).

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.
