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

chat-messaging 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.

What it actually says

Chat & Messaging Patterns

Message Bubbles

  • Sent messages: Right-aligned, brand/accent color background
  • Received messages: Left-aligned, neutral/gray background
  • Status indicators: Sent (single check), Delivered (double check), Read (blue/colored check)
  • Timestamps: Show for each message or group by time (messages within 5 minutes share a timestamp)

Input Area

  • Multi-line text input that grows with content (up to ~4 lines, then scroll)
  • Attachment button (files, images, audio)
  • Emoji picker
  • Send button (enabled only when input has content)
  • Shift+Enter for new line, Enter to send

Typing Indicator

  • Show "[Name] is typing..." with animated dots
  • Position: bottom of message list, left-aligned
  • Show for 3-5 seconds after last keystroke
  • Multiple users: "[Name] and [Name] are typing..."

Real-Time

  • New messages appear at the bottom
  • Auto-scroll to bottom on new message (only if already at bottom)
  • "New messages" indicator if user scrolled up
  • Optimistic send (show message immediately, confirm silently)

Message Types

Type Display
Text Bubble with rendered markdown
Image Thumbnail with lightbox on click
File File icon + name + size, click to download
Audio Mini waveform player
Link Rich preview (OG image, title, description)
System Centered, muted text, no bubble

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.
