deep-research

deep-research is a skill for Claude Code, Codex from airvalona/antigravity-like-claude-code. It costs 68 tokens per session (422 once invoked), scanned A, original, MIT.

A multi-step research workflow for broad questions, comparisons, and investigations. It breaks the subject into smaller questions, searches each angle, follows up on gaps, and combines the findings into a synthesis.

In plain words
What is it for?
It helps investigate products, technologies, migrations, comparisons, and other questions that require several focused searches and a structured final analysis.
Why use it?
A single search often gives shallow or incomplete coverage of a complex topic. This workflow helps expose missing angles and favors original sources such as official documentation and research papers.

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 9d 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 — Multi-Step Research Workflow

Port of Claude Code's bundled deep-research skill.

When to use

Broad or multi-part questions, comparisons, or anything where a single search would only give a surface-level answer — not simple factual lookups.

Steps

  1. Break the topic into sub-questions. Before searching, list the distinct angles that need covering (e.g. for "should we migrate to X", that's: what X is, current adoption/maturity, migration cost, comparison to current stack, known pitfalls).

  2. Search each angle separately. Don't combine multiple sub-questions into one search query — it returns shallow results for all of them. Use short, specific queries (2-6 words), starting broad and narrowing based on results.

  3. Follow up on gaps. After the first pass, check which sub-questions are still thin and search again with reformulated queries or more specific terms.

  4. Prefer primary sources (official docs, source repos, original announcements) over aggregator/blog summaries when both are available.

  5. Synthesize, don't just list. The final answer should be organized around the sub-questions, not around which search produced which fact. Note where sources disagree rather than silently picking one.

  6. Cite sources by name/link so the user can verify anything load-bearing.

Notes

Scale the number of searches to the complexity of the question — a handful for a medium comparison, more for something genuinely open-ended. Stop once every sub-question is actually grounded in something retrieved, not just plausible.

Changes

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.
