A web-research workflow for facts that people may rely on, such as dates, prices, rules, versions, statistics, and news. It requires opening primary or official pages rather than trusting search-result summaries.

In plain words
What is it for?
Use it to verify deadlines, fees, eligibility, schedules, software versions, scientific or public facts, and other time-sensitive claims.

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

verified-research scanned grade A with 1 finding 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 26d 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.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use search results to find pages, and take facts only from the pages. A snippet is an engine's summary of a page as it looked when it was crawled: it drops qualifiers, merges editions, and is often years old. Use this workflow whenever someone will rely on the answer.

Tool names below are the bare names on the search MCP server; your host may show them with a prefix.

0. Fix today's date

Know today's date before judging anything as current. Take it from your system context. Failing that, the retrieved … stamp on a fresh (uncached) search result is the server's clock. "Latest", "this year" and "upcoming" are relative to it. Do not infer the current year from search results or from memory.

1. Locate: search is for URLs only

  • search(query) finds candidate pages. Add freshness="month" (or "day"/"week"/"year") when recency matters, include_domains=[...] once you know the official domain, category= for papers, filings, news, datasets.
  • Some facts have a registry, and the search asks it on its own when the question names the thing plainly: a package ("latest fastapi version"), a CVE id, two currencies ("100 usd to cny"), a place and a weather word, a country and an indicator ("china gdp"), a city and a time word, a domain, a coin, an iOS app. The record comes back as the first result with the publisher's date, marked "Record sources", and can be cited as it is. category= ("software", "security", "weather", "finance.fx", "stats", "calendar", "reference") asks the same sources explicitly.
  • Pick the primary source: the organizer's, vendor's, regulator's or author's own page, the filing, the paper, the repository. Aggregators, listicles, reposts, forums and AI-written summaries are useful only for finding it.
  • Never copy a date, amount, name, rule or number from a snippet or the Lead: line into your answer.
  • Search in the language of the source. A Chinese query is routed to a Chinese index automatically; to force more of them use engines=["so360", "baidu"].

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.
