deep-research

deep-research is a skill for Claude Code from coreyhaines31/makerskills. It costs 201 tokens per session (1,346 once invoked), scanned B, original, MIT.

Instructions for a multi-source research skill that investigates a question, combines findings, and saves the results for later use. It can use web search, recent online discussions, specific pages, browser access, and stored research.

In plain words
What is it for?
Use it for competitor research, market research, partnership checks, technology decisions, or any topic that needs several sources and a clear synthesis.
Why use it?
It helps turn a broad research request into a focused question and a deliberate source plan. Saving the results makes previous research available for future work.

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 B, and why

deep-research scanned grade B with 1 finding 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.

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.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/deep-research — Multi-source research with archive

Plans, executes, and synthesizes research from multiple sources. Archives the output so the corpus compounds.

Step 1 — Frame the question

Restate the research question in one tight sentence. If ambiguous, ask the user:

  • What's the decision this research will inform?
  • What's the minimum useful answer? (Saves over-researching.)
  • Any sources to prioritize or avoid?

Output: **Research question:** <one sentence>

Step 2 — Plan the sources

Pick from this menu based on the question type. Note which sources you'll hit and why.

Source When to use Tool
Web search (Google) Authoritative articles, docs, official statements WebSearch
/last30days What people are actually saying right now — Reddit, X, YouTube, HN, web recency Skill({skill: "last30days", args: "<topic>"})
Specific URLs When the user hands over starting URLs WebFetch
Browsable pages (auth-walled, JS-heavy) Pricing pages, product tours, profiles agent-browser via the compound-engineering:agent-browser skill
Memory Prior research / decisions / context the user already captured grep ~/.claude/memory/
Notion If the topic touches a known Notion workspace Direct Notion API (key in $NOTION_API_KEY, see reference_notion_api.md)
Research archive Prior /deep-research runs that touched this topic grep ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/deep-research/archive/

Run discovery passes in parallel where possible. Sequential only when one source needs another's output (e.g., agent-browser a URL discovered by WebSearch).

Step 3 — Execute discovery

Run each chosen source. For each result, capture:

  • The source (URL or system)
  • 1–3 sentence summary of what was said
  • Date / recency
  • Confidence in the source (high/medium/low)

Don't synthesize yet — just collect.

Step 4 — Synthesize

  1. Group findings by theme or sub-question
  2. Contradiction check — flag anywhere sources disagree. Don't average them; surface the disagreement.
  3. Confidence: high (multiple independent sources agree), medium (one strong source or several weak), low (single anecdote or speculation)
  4. Gaps: what would change the answer? What's NOT in the corpus?

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.
