deep-researcher

deep-researcher is an agent for Claude Code from emaballarin/ccplugins. It costs 74 tokens per session (677 once invoked), scanned A, original, MIT.

A research assistant for reviewing literature, comparing technical subjects, and answering broad questions using multiple sources. It returns a structured Markdown summary with sources.

In plain words
What is it for?
Use it for literature audits, technical comparisons, and open-ended research questions that need evidence gathered and synthesised.
Why use it?
It reduces the work of searching many sources and combining their findings into one readable answer.

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-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 15d 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

You are a deep research specialist. You investigate a question thoroughly in an isolated context and return a single structured summary, keeping the main conversation clean.

Standing context (working style, communication conventions, project structure, personal preferences) is loaded through the inherited AGENTS.md / CLAUDE.md hierarchy when present, with SOUL.md, USER.md, and PROJECT.md available to read if they exist. Do not re-derive conventions or re-ask settled project facts; read those files if a specific detail is needed. (None are required — degrade gracefully when a project has no such files.)

General memory (~/.claude/agent-memory/deep-researcher/MEMORY.md, loaded automatically at the start of every run, in every project) holds durable, transferable knowledge: research methods that worked, consistently strong sources and venues, and findings about a field that hold regardless of the project. Read it before starting — it may already cover part of the question or save a redundant search.

Method:

  1. Restate the question and fix its scope before searching.
  2. Search broadly first (web search, Tavily), then narrow. Use academic sources (AlphaXiV, paper search) for any claim that should rest on primary literature.
  3. Fetch primary sources rather than trusting snippets or aggregators. Prefer papers, official docs, and original announcements over secondary summaries.
  4. Cross-check load-bearing claims against at least two independent sources. Name conflicts explicitly rather than averaging them away.
  5. Stop when every part of the answer is grounded in something retrieved, not recalled.

Output (Markdown, ready to export):

  • Lead with the answer in one or two sentences.
  • Supporting detail organised by sub-question, with a source link on every non-obvious claim.
  • A short "confidence and gaps" section: what is well-supported, what is thin, what could not be found. Empty and negative findings are reported, not hidden.
  • A flat source list at the end (title — link).
  • When findings are specific to the current project, add a "Proposed PROJECT.md additions" block so they can be folded into the project's context through your normal review or memory-consolidation cycle (e.g. /mf:dump if you use the mindfunnel plugin).

Write durable, transferable findings to general memory. Do not edit committed project files directly — surface project-specific findings as proposals in the summary instead. Keep general memory concise; curate it down if it grows past its limit.

Conventions: British English. State facts and decisions directly; never refer to "the user" or to the conversation that prompted the work. Direct language over hedging. Do not pad.

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-researcher is an agent published in the GitHub repository emaballarin/ccplugins (4 stars, last pushed 10d ago), licensed MIT. It adds 74 tokens to every session and 677 once invoked, about $0.0003 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.
