What it does
Deep Research is an agent skill from coreyhaines31/makerskills. When you want multi-source, multi-step research on a topic — competitor research before a sales call, market research for a new business idea, positioning angles, due diligence on a partnership or podcast guest, tech decision research (which DB, which auth), or any "I need to actually understand X." Combines web search, URL fetch, agent-browser, last30days (Reddit/X/YouTube/HN/web recency), memory, and Notion. Outputs a structured brief with citations, contradictions, gaps, and recommended next steps. Archives…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Deep research, Web search and Browser automation. It works with Notion, Reddit and YouTube. The repository describes itself as: AI agent skills for the personal operator's craft — decisions, research, second-brain, content rotation, scenario modeling, and meta-skills to author more. Works with Claude… The licence is MIT.
When your agent uses it
- Do a deep dive on X
- Whats actually happening with X
- Due diligence on X
- Validate this market. Differs from a one-shot web search: this is multi-pass with verification
Example prompts
- “I need to actually understand X.”
- “/deep-research,”
- “research X,”
- “/deep-research”
Requirements
- A credential in NOTION_API_KEY
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cc31579. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
NOTION_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Deep Research loads about 1.4k tokens when it runs. Until then it costs about 220 tokens; SKILL.md has 536 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

/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 | How (tool names vary by agent) |
|---|---|---|
| Web search (Google) | Authoritative articles, docs, official statements | Your agent's web search (e.g. WebSearch in Claude Code) |
/last30days | What people are actually saying right now — Reddit, X, YouTube, HN, web recency | The last30days skill, if installed. Otherwise skip it and note the gap |
| Specific URLs | When the user hands over starting URLs | Your agent's URL fetch (e.g. WebFetch), or curl + defuddle |
| Browsable pages (auth-walled, JS-heavy) | Pricing pages, product tours, profiles | agent-browser CLI (any agent with a shell) |
| Memory | Prior research / decisions / context the user already captured | your agent's memory, or grep ${MAKERSKILLS_MEMORY:-${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/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 web search).
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
- Group findings by theme or sub-question
- Contradiction check — flag anywhere sources disagree. Don't average them; surface the disagreement.
- Confidence: high (multiple independent sources agree), medium (one strong source or several weak), low (single anecdote or speculation)
- Gaps: what would change the answer? What's NOT in the corpus?
Show full SKILL.md (209 more words)Show less
Step 5 — Output the brief
Use this template:
# Research: <question>
**Date:** <YYYY-MM-DD>
**Decision this informs:** <one line>
**Confidence overall:** high / medium / low
## TL;DR
<2–4 sentences with the answer>
## Key findings
### 1. <Finding>
<2–4 sentences>. Sources: [1], [3], [5]
### 2. <Finding>
...
## Contradictions / uncertainty
- <where sources disagree, with each side cited>
## Gaps
- <what's missing from the corpus>
- <what to research next to close the gap>
## Recommended next steps
1. <action>
2. <action>
## Sources
[1] <Title> — <URL or system> (<date>) — <confidence>
[2] ...Step 6 — Archive
Archives live in ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/deep-research/archive/ (create the directory if missing). Never write archives inside the skill's own folder — skill installs and upgrades re-sync from source and wipe anything saved there. Migration: if this skill's folder contains an old references/research-archive/ with user entries, move those files into the archive directory first.
Write the brief to <archive dir>/<YYYY-MM-DD>-<slug>.md so it's grep-able forever. Slug = kebab-case of the topic.
Also append a one-line entry to <archive dir>/INDEX.md (create if missing):
- 2026-06-15 — [<topic>](./<filename>.md) — <one-line TL;DR>Step 7 — Surface
After archiving:
- Show the full brief in chat
- Tell the user the archive path
- Offer: "Push to Notion or save to a project's docs?"
Composes with
business-brainstorm— calls this skill during the market validation step/domain— when research includes "is the .com available"/last30days— one of the data sources
Notes on quality
- Always cite. Every claim in the brief needs a source pointer.
- Recency matters — note dates on each source. For fast-moving topics (AI, startups), de-weight sources >12 months old.
- Don't trust a single source for high-stakes claims. Re-search until you have at least 2 independent corroborations or surface the uncertainty.
- No padding. If the answer is one paragraph, return one paragraph. The template is a maximum, not a minimum.
