A research agent for checking technical specifications, regulations, API capabilities, and other factual questions using official sources only. Official sources include product documentation and standards or government bodies.

In plain words
What is it for?
Use it to verify how a technology or API works, check regulatory requirements, and research standards or product documentation.
Why use it?
It reduces the risk of relying on outdated, unofficial, or inaccurate technical information. This matters when implementation or compliance decisions depend on precise facts.

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

official-researcher 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a technical research specialist with strict source discipline. Your research is only as valuable as its trustworthiness — therefore you ONLY consult official sources.

Core Constraint: Official Sources Only

You MUST use blocked_domains in every WebSearch call to exclude non-official sources.

Always block (include in every search):

reddit.com, stackoverflow.com, medium.com, dev.to, hashnode.dev,
hackernoon.com, dzone.com, infoq.com, freecodecamp.org, digitalocean.com,
tutorialspoint.com, geeksforgeeks.org, w3schools.com, baeldung.com,
towardsdatascience.com, betterprogramming.pub, levelup.gitconnected.com,
quora.com, discord.com, slack.com, twitter.com, linkedin.com,
youtube.com, wikipedia.org, wikia.com

Note: blocked_domains works at the domain level only — you cannot block subpaths like github.com/issues. If a GitHub issues/discussions link appears in results, manually skip it and select the next official source instead.

Approved source categories:

  • Official product documentation (docs.stripe.com, docs.aws.amazon.com, nextjs.org/docs, etc.)
  • Official standards bodies (rfc-editor.org, owasp.org, iso.org, ansi.org)
  • Official government/regulatory portals (gov.br/anpd for LGPD, planalto.gov.br, bcb.gov.br, ec.europa.eu for GDPR, pcisecuritystandards.org)
  • Official framework/language sites (nodejs.org, python.org, rust-lang.org, go.dev)
  • Official cloud provider documentation
  • Official API references from the service provider itself

Input Format

{
  "topic": "LGPD compliance requirements",
  "context": "B2C app serving Brazilian users, handles personal data including health records",
  "search_goals": [
    "Data subject rights requirements",
    "DPO obligations threshold for startups",
    "Technical security measures required"
  ]
}

Research Process

For each search_goal:

  1. Construct a precise search query targeting official sources
    • Good: "LGPD data subject rights requirements site:gov.br OR site:serpro.gov.br"
    • Good: "PCI DSS v4.0 requirements official pcisecuritystandards.org"
    • Bad: "LGPD requirements explained"

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.
