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

third-party-bloat 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 10d 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.

Third-Party Bloat

Find out which third-party scripts are weighing your page down. No signup required.

Prerequisites

  • Playwright MCP (comes with Claude Code)

Trigger

  • "What third-party scripts are slowing my site?"
  • "Third-party bloat audit https://..."
  • "Which trackers are on my page?"

Workflow

  1. Navigate to the URL using mcp__playwright__browser_navigate

  2. Wait for load to settle, then pull every request with mcp__playwright__browser_network_requests

  3. Classify each request as first-party (same registrable domain as the page) or third-party. Group third-party requests by their domain and sum transfer size + request count per domain.

  4. Label well-known vendors by domain so the report is readable, e.g.:

    • google-analytics.com, googletagmanager.com → Analytics / Tag Manager
    • doubleclick.net, googlesyndication.com → Ads
    • connect.facebook.net → Meta Pixel
    • intercom, crisp.chat, hotjar, fullstory → Chat / Session replay
    • optimizely, launchdarkly → A/B / Flags
  5. Estimate main-thread cost: count third-party <script> resources and note any loaded synchronously in <head> (these block parsing). Flag session-replay / heatmap tools specifically — they tend to be the most expensive.

  6. Output:

## Third-Party Bloat Report: [URL]

**18 third-party requests across 7 domains — 1.4 MB (44% of page weight)**

### Heaviest offenders
| Vendor                  | Size   | Requests | Note |
|-------------------------|--------|----------|------|
| Hotjar (session replay) | 620 KB | 5        | Loaded sync — blocks main thread |
| Google Tag Manager      | 310 KB | 4        | Fans out to 3 more tags |
| Intercom (chat)         | 280 KB | 3        | Could lazy-load on scroll |
| Meta Pixel              | 90 KB  | 2        | —    |

### Recommendations
1. Defer Hotjar until after `load`, or sample fewer sessions.
2. Lazy-load the Intercom widget on first scroll / click.
3. Audit GTM — it's pulling tags you may not still use.

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.
