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

web-reader 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.

What it actually says

Web Reading

Purpose

Converts any URL into clean Markdown text, removing ads, navigation, styling, and other distractions. Suitable for:

  • Reading API documentation (tushare, OKX, yfinance, and similar)
  • Reading technical articles and blogs
  • Retrieving research reports and announcements
  • Reading GitHub README / Wiki pages

Usage

Call the read_url tool directly (do not use bash + requests, call the tool directly):

read_url(url="https://tushare.pro/document/2?doc_id=27")

Returns JSON:

{
  "status": "ok",
  "title": "Page title",
  "url": "Original URL",
  "content": "Page content in Markdown format",
  "length": 12345
}

Notes

  • Content longer than 8000 characters will be truncated, with the total length noted at the end
  • Dynamically rendered SPA pages may return only skeleton HTML
  • Chinese content is supported normally

Privacy & freshness

  • Third-party dependency: read_url forwards the full target URL (including any query string) to the external Jina Reader service (r.jina.ai). Do not pass URLs containing credentials, tokens, or private/internal addresses — they would leave this host.
  • Caching/staleness: results may be a cached snapshot, not live data. When stale, the JSON includes "cached": true; pass no_cache=true to force a fresh fetch (slower — use only when freshness matters).
  • Bash fallback caveat: if a site blocks the reader (e.g. HTTP 451) a manual bash + requests fetch is possible, but it bypasses this tool's URL safety guard and the Jina layer — use sparingly and never for internal/authenticated URLs.

Common Usage

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.
