deep-research

deep-research is a skill for Claude Code from tuan3w/obsidian-vault-agent. It costs 186 tokens per session (3,380 once invoked), scanned A, original, MIT.

A research workflow for investigating complex or contested topics through multiple rounds and sources. It explores different perspectives, checks for contradictions, and records citations and confidence levels.

In plain words
What is it for?
Use it for thorough research, complex decisions, comparisons supported by evidence, and topics that need more than a short answer.
Why use it?
A quick search can miss important viewpoints or leave conflicting claims unresolved. This organizes a deeper investigation before producing a comprehensive research note.

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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/search_papers.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

The architecture is inspired by Stanford's STORM (perspective discovery + outline-first), Anthropic's multi-agent research system (parallel exploration + intelligent critique), and pi-autoresearch (living state files that survive context resets).

<Use_When>

  • User wants DEEP understanding, not a quick summary
  • Topic is complex, contested, or multi-faceted
  • User needs to make a decision based on the research
  • User wants to compare competing approaches with evidence
  • User explicitly asks for /deep-research or "thorough research" </Use_When>

<Do_Not_Use_When>

  • User wants a quick answer (use /research instead)
  • User wants to find academic papers specifically (use /paper-discover)
  • User wants to process an existing vault note (use /process)
  • User wants cross-domain vault synthesis (use /synthesize) </Do_Not_Use_When>

Stage 0: SETUP

Parse $ARGUMENTS for the topic and optional depth flag:

  • --quick: faster, fewer rounds, sonnet everywhere, no perspective discovery
  • --deep: more rounds, opus for critic and synthesis, outline reviewed by user
  • Default (no flag): balanced — perspective discovery, 2-4 rounds, opus for synthesis

Create the workspace:

TOPIC_SLUG=$(echo "$TOPIC" | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/-/g' | sed 's/--*/-/g' | cut -c1-30)
WORK_DIR="temp/research-${TOPIC_SLUG}"
mkdir -p "$WORK_DIR"/{findings,gaps}

Resume check: Before creating, check if the workspace already exists:

ls "$WORK_DIR/state.md" 2>/dev/null

If state.md exists, read it and ask the user: "Found incomplete research on [topic] (round N). Resume or start fresh?" If resuming, read state.md to determine which stage to skip to.

Tell the user what's happening:

Deep researching "{topic}" ({depth mode}).
Setting up workspace at {WORK_DIR}...

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

deep-research is a skill published in the GitHub repository tuan3w/obsidian-vault-agent (39 stars, last pushed 5mo ago), licensed MIT. It adds 186 tokens to every session and 3,380 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings.
