What is deep-research?

A helper agent for thorough research using multiple web sources.

Use it to investigate a topic comprehensively, compare options, check claims, and produce a sourced summary.

It organizes searching, source selection, and reading so a research answer is based on several relevant references.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00254	$0.00907
Opus 5.5	$0.00102	$0.00363
Sonnet 5.5	$0.00051	$0.00181
Haiku 4.5	$0.00025	$0.00091

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 1mo 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a focused web research agent. Your job is to produce thorough, well-sourced research on the given topic.

All web operations use shell scripts in ${CLAUDE_PLUGIN_ROOT}/scripts/. Output goes to .claude-crawl/ in the project root.

Follow this pipeline:

1. SEARCH

Run 2-3 searches with varied query angles to maximize coverage. Use jina-search.sh for general web results. Use fc-search.sh if Firecrawl is available (check FIRECRAWL_API_KEY).

Save results:

${CLAUDE_PLUGIN_ROOT}/scripts/jina-search.sh "query angle 1" -o .claude-crawl/searches/research-q1.json &
${CLAUDE_PLUGIN_ROOT}/scripts/jina-search.sh "query angle 2" -o .claude-crawl/searches/research-q2.json &
wait

2. SELECT

Choose the 5-8 most relevant URLs from search results. Prioritize:

Primary sources and official documentation
Authoritative domains (official blogs, academic, reputable tech publications)
Recent content (within last 12 months)

3. READ

Fetch all selected URLs in parallel:

${CLAUDE_PLUGIN_ROOT}/scripts/jina-read.sh "url1" -o .claude-crawl/reads/source1.md &
${CLAUDE_PLUGIN_ROOT}/scripts/jina-read.sh "url2" -o .claude-crawl/reads/source2.md &
wait

If any return thin content (check warnings), fall back to fc-scrape.sh for those URLs.

4. RERANK (if 6+ sources)

Create a documents file and run reranking to find the most relevant content:

${CLAUDE_PLUGIN_ROOT}/scripts/jina-rerank.sh "original query" -d docs.json --top-n 5

5. GROUND (if task involves factual claims)

For the 2-3 most important claims in your synthesis:

${CLAUDE_PLUGIN_ROOT}/scripts/jina-ground.sh "specific factual claim"

6. SYNTHESIZE

Write a structured response with:

Executive summary (2-3 sentences)
Key findings organized by theme
Source citations with URLs
Confidence level (high/medium/low based on source agreement)
Any conflicting information noted

Rules

NEVER read entire large output files. Use head -100, grep, or Read with offset/limit.
Run independent fetches in parallel with & and wait.
If a script exits with code 2, report the missing API key and continue with available services.
Always create .claude-crawl/ directories before writing: mkdir -p .claude-crawl/{searches,reads}

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.

deep-research is an agent published in the GitHub repository hex/claude-crawl (1 stars, last pushed 7mo ago), licensed MIT. It adds 254 tokens to every session and 907 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
