Deep Research (multi-source research with archive)

A multi-pass research workflow that plans sources, cross-checks them, and outputs a cited brief with contradictions and gaps — then archives every run for later grepping.

What it does

Turns a vague ask into one sharp research question, and asks what decision the research will inform so it doesn't over-research.
Picks sources deliberately: web search for authoritative docs/articles, user-supplied URLs, a browser CLI for auth-walled or JS-heavy pages, last30days for what people are actually saying on Reddit/X/YouTube/HN, prior memory and past research archives, plus Notion when relevant.
Runs discovery in parallel where possible, recording source, a 1–3 sentence summary, date, and confidence for each hit.
Synthesis groups findings by theme, surfaces contradictions instead of averaging them, assigns confidence levels, and names the gaps that would change the answer.
Emits a templated brief (TL;DR, key findings, contradictions, gaps, next steps, numbered sources) and writes it to ~/.config/makerskills/deep-research/archive/ with an INDEX.md line so the corpus compounds.

Who it's for

Sales/BD folks prepping competitor or account intel before a call.
Founders and PMs validating a market or testing positioning angles.
Engineers and tech leads documenting a DB/auth decision with evidence.
Anyone doing due diligence on a partner, investment, or podcast guest.

Example uses

"Do a deep dive on competitor A" → cross-checks the official pricing page, recent Reddit/HN complaints, and review articles into a strengths/weaknesses brief.
"Validate this market" → compares market-size reports against real user chatter, flags conflicting numbers on both sides, and lists what to verify next.
"Clerk vs Supabase Auth?" → pulls official docs plus community experience from the last 12 months into a confidence-tagged comparison, archived for future reference.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/coreyhaines31/makerskills/HEAD/skills/deep-research/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)

Download the ZIP with the button below.
In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

↓ Download ZIP

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/deep-research folder from the GitHub repo coreyhaines31/makerskills into my ~/.claude/skills/coreyhaines31-deep-research/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/coreyhaines31/makerskills.git && mkdir -p ~/.claude/skills && cp -r makerskills/skills/deep-research ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

Open a terminal.
Clone the repo: git clone https://github.com/coreyhaines31/makerskills.git
Create the skills folder: mkdir -p ~/.claude/skills
Copy the skill in: cp -r makerskills/skills/deep-research ~/.claude/skills/
(Optional) Pre-create the archive dir: mkdir -p ~/.config/makerskills/deep-research/archive
(Optional) For Notion push, add export NOTION_API_KEY=... to your shell profile; for community recency, also install the last30days skill from the same repo.
Restart Claude Code, then try research competitor X or /deep-research to confirm it triggers.
