deep-research

deep-research is a skill for Claude Code, Codex from keysersoose/claude-code-setup. It costs 71 tokens per session (2,120 once invoked), scanned A, original, MIT.

A source-backed workflow for answering research questions with an agent-written brief and saved source material. It is intended for literature reviews, technical investigations, market research, and current-state analysis.

In plain words
What is it for?
Use it to gather, capture, assess, and cite information for a research brief.
Why use it?
It makes important claims traceable to sources and distinguishes facts from interpretation, uncertainty, and missing evidence.

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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/batch_capture.py, scripts/test_batch_capture.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.

Deep Research

Overview

Use this skill for research where claims must be traceable to sources. It is harness-neutral, but the default discovery-to-capture path is explicit: use sibling advanced-web-search/scripts/opencli_google_search.py to save candidate URLs as JSON, then use this skill's scripts/batch_capture.py --search-json to crawl them with Crawl4AI, then read the raw markdown and write the final brief.

Runtime requirement: Crawl4AI must be installed for raw capture. Install with python -m pip install -U crawl4ai, then run crawl4ai-setup and crawl4ai-doctor. See ../crawl4ai/SKILL.md.

Operating Contract

  1. Prefer official, primary, and direct sources.
  2. Use multiple targeted query classes, not one broad query.
  3. Treat search snippets as leads, not evidence.
  4. Inspect extraction quality; do not treat HTTP success as content success.
  5. Separate facts, interpretation, recommendations, counter-evidence, open questions, and confidence.
  6. Cite material claims with URLs or local raw/source artifact paths.
  7. Label blocked, partial, old, borderline, and inferred evidence.
  8. For durable research, write artifacts in the Hermes Obsidian layout, not a generic flat folder.

Workflow

Phase 0: Scope

Restate the question, decision target, constraints, time window, output format, and source classes needed. Ask a concise clarifying question only if ambiguity changes the source universe or tool calls materially.

Completion: scope is clear enough to define at least four query classes.

Phase 1: Discovery

Use advanced-web-search/scripts/opencli_google_search.py when it is available. Do not use a harness built-in web search as the primary discovery step when OpenCLI is available. Read references/query-patterns.md when constructing the search plan.

Always save discovery output to a JSON file with --output:

python ../advanced-web-search/scripts/opencli_google_search.py \
  --query "Hybrid XBRL tagging after:2026-03-01" \
  --query "site:github.com XBRL AI tagging after:2026-03-01" \
  --max-results 30 \
  --pages 8 \
  --output outputs/hybrid_xbrl_sources.json

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 keysersoose/claude-code-setup (2 stars, last pushed 1mo ago), licensed MIT. It adds 71 tokens to every session and 2,120 once invoked, about $0.0004 per session on Opus 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.
