deep-research

deep-research is a skill for Claude Code, Codex from omnigent-ai/omnigent. It costs 31 tokens per session (478 once invoked), scanned A, original, Apache-2.0.

A procedure for answering questions with thorough web research, source checking, and citations. It uses focused searches, reads the full pages, and compares independent sources.

In plain words
What is it for?
Use it for current or otherwise verifiable questions that need a research report. It helps plan search topics, gather relevant pages, cross-check important claims, and cite the evidence.
Why use it?
It reduces the risk of relying on outdated information, search-result snippets, or a single unverified source.

About the project

Omnigent is an open-source orchestration layer for running and coordinating different AI coding agents through one system. It is for developers who want to combine agents, apply policies and sandboxing, and continue sessions across devices. The catalogue add-ons extend its agent workflows.

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

deep-research 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 6d 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

deep-research — cited, cross-checked web research

Use this for any question that needs current, verifiable information from the web. The deliverable is a synthesized answer where every load-bearing claim is backed by a source you actually read.

Tools

  • search_web_pages(query, [site], [published_after], [published_before], [mode]) — discover candidate sources. Write the query as a natural-language description of the ideal page, not keywords. Use mode: pro (default).
  • fetch_page_content(url, [max_chars]) — read the full page (markdown). A search snippet is NEVER sufficient evidence — fetch before you cite.

Procedure

  1. Plan. Break the question into 3-6 focused sub-queries that together cover it. For contested or high-stakes questions, plan at least two independent angles.
  2. Search. Run search_web_pages per sub-query. Prefer primary sources; use published_after for anything time-sensitive.
  3. Read. fetch_page_content on the 2-3 most promising results per sub-query. Quote/cite only what you read, not what a snippet implied.
  4. Cross-check. Verify every load-bearing claim against ≥2 INDEPENDENT sources (independent = different owners, not mirrors of one another). When sources disagree, surface the disagreement rather than picking silently.
  5. Synthesize. Write a structured answer. Each non-obvious claim gets an inline citation to the URL you fetched. Separate "well-supported" from "uncertain / single-source".
  6. Cite. End with a Sources list of the URLs you actually fetched.

Notes

  • Don't answer from prior knowledge with a disclaimer — search and read first.
  • If coverage is thin or sources conflict irreconcilably, say so explicitly; an honest "the evidence is mixed" beats false confidence.
  • Keep each sub-query narrow enough that a couple of fetches resolve it.

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.
